Legal, privacy and data rights.

Overview

Proof is an independent evidence ledger for arable systems. These legal pages explain how Proof operates, how records become public, what stays private, and the rules that govern contributors, evidence, website use and commercial access.

Every locked Proof Record creates two linked artefacts:

The public redacted record. A public, citable record showing what was tested, against what control, under what conditions, what happened, what evidence supports it, what conflicts exist, and what changed after lock.

The private envelope. A controlled data layer containing exact farm identity, exact field data, raw evidence files, EXIF data, private notes and commercially sensitive material.

Public Proof Records are append-only. Corrections and clarifications happen through visible addenda, redaction updates and Evidence Queries — not silent edits.

Proof does not sell farm data, run paid product rankings, accept advertising on public record pages, or allow records to be hidden because an outcome is commercially inconvenient.

The documents below form the legal and operational framework for Proof.

How to make a privacy or data rights request.

Proof respects the data rights set out in UK data protection law. You can ask to access, correct, delete, restrict or receive a copy of your personal data where those rights apply.

1. 01Email ct@proof.ag with the subject line "Privacy request".
2. 02Tell us which right you want to exercise and the personal data your request concerns.
3. 03If your request relates to a Proof Record, contributor account, application, farm contact or private envelope, include any relevant reference, such as a record UID, account email or organisation name.
4. 04We may need to verify your identity, or your authority to act for someone else, before responding.
5. 05We will respond within the time required by UK data protection law. In most cases, this means without undue delay and within one calendar month of receiving a valid request.

For the full procedure, see Privacy Notice — How to make a privacy request →

Separate terms apply.

Contributor accounts and commercial access to Proof are governed by separate terms in addition to the Website Terms.

The Contributor Terms apply to people and organisations who create, manage or contribute to Proof Records. They cover contributor eligibility, farm authority, record creation, evidence uploads, public redacted publication, private envelope handling, conflict declarations, addenda, Evidence Queries, exports, account status and misuse.

The Commercial Terms apply where Proof provides commercial access, including attestation, analytics, infrastructure and API access, research partnerships or other scoped commercial services.

Commercial access does not change the public ledger. It does not permit record suppression, paid ranking, advertising, private envelope access without authorisation, or control over public evidence.

How to reach Proof on legal matters.

Please do not send identity documents, raw evidence files, exact farm data or confidential commercial material by email unless Proof asks you to do so. We will tell you if we need further information to handle your request.

Privacy Notice

This notice explains how Proof handles personal data under UK data protection law. It covers website visitors, contributor applicants, contributors, authorised farm contacts and personal data held inside Proof workflows.

Proof is operated by PROOF AG LTD, a company registered in England and Wales with company number 17211914.

In this notice, "Proof", "we", "us" and "our" mean PROOF AG LTD.

Proof is the data controller for personal data processed in the course of operating the Proof website, contributor applications, contributor accounts, commercial relationships, public Proof Records and related Proof workflows.

Please do not send identity documents, raw evidence files, exact farm data or confidential commercial material by email unless Proof asks you to do so.

The personal data Proof collects depends on how you interact with the service. The categories below are organised by role so you can see what may be collected in each context.

Website visitors

Contributor applicants

Contributors

Farm contacts and authorised parties

Private record and evidence data

Special category data

Proof does not knowingly collect or require special category personal data, such as health information, ethnicity, religion, political opinions, trade union membership, biometric or genetic data, sex life or sexual orientation data, in the course of operating the evidence ledger.

Please do not submit special category data through Proof workflows.

Proof collects personal data in the following ways:

1. 01Directly from you when you submit a contact form, send an email, apply to contribute, create an account, configure your profile, upload evidence, create a record or take part in Proof workflows.
2. 02Automatically through the website through essential cookies, server logs and security monitoring.
3. 03From contributors acting on behalf of farms or organisations where an agronomist, farm manager, researcher or trial partner records information under a permission or access relationship.
4. 04From authorised third parties where you or an authorised organisation instructs an integration, support workflow or data import.
5. 05From public sources where needed to assess contributor applications, conflicts, affiliations, commercial context or Evidence Queries.

Proof uses personal data for the following purposes.

Under UK data protection law, Proof must have a lawful basis for processing personal data. The lawful basis depends on the purpose.

Where Proof relies on legitimate interests, it considers the purpose of the processing, whether the processing is necessary, and the impact on the individual. Privacy controls, redaction, private envelopes, access permissions and limits on commercial access are part of that balancing exercise.

Proof keeps personal data only for as long as needed for the purpose for which it was collected, including record integrity, contributor services, legal obligations, security, dispute resolution and the permanent nature of public Proof Records.

Some records may be retained for longer where required by law, where necessary to establish, exercise or defend legal claims, or where required to preserve the integrity of a locked Proof Record.

Proof shares personal data only where necessary and lawful.

Proof does not sell personal data. Proof does not share personal data with advertising networks. Proof does not sell or license private farm envelope data to commercial customers.

Some of Proof's service providers may process personal data outside the United Kingdom.

Where personal data is transferred outside the UK, Proof uses safeguards recognised under UK data protection law. These may include UK adequacy regulations, the UK International Data Transfer Agreement, the UK Addendum to EU Standard Contractual Clauses, or another lawful transfer mechanism.

Proof aims to use reputable service providers with appropriate security, contractual and transfer safeguards.

Proof uses technical and organisational measures designed to protect personal data against unauthorised access, accidental loss, destruction or damage.

These measures include:

• ·access controls on contributor accounts;
• ·separation of public records from private envelope data;
• ·permissioned access to farm, field and raw evidence data;
• ·encryption in transit;
• ·hashing of evidence files and locked records;
• ·audit logging for sensitive actions;
• ·redaction workflows for public projections;
• ·restricted internal access to private envelope material.

No system can be made absolutely secure. Proof's commitment is to operate reasonable controls appropriate to the sensitivity of the data, to reduce risk, and to handle incidents transparently.

For the plain-English explanation of the public/private boundary, see /data-and-privacy.

Under UK data protection law, you may have the following rights.

Limits on rights · record integrity

Some rights may be limited where the personal data concerned forms part of an immutable Proof Record, where retention is required by law, or where deletion would compromise the integrity of the public ledger.

Any limitation will be assessed case by case and explained. The Proof model is permanent public evidence with addenda, redaction and Evidence Queries where appropriate — not silent deletion of locked public records.

To exercise any of the rights set out in section 11:

1. 01Email ct@proof.ag with the subject line "Privacy request".
2. 02Tell us which right you want to exercise and the personal data it concerns. Be as specific as you can.
3. 03Include any relevant reference, such as a record UID, account email, organisation name, application email or farm relationship.
4. 04We may need to verify your identity, or your authority to act for someone else, before responding.
5. 05We will respond within the time required by UK data protection law. In most cases, this means without undue delay and within one calendar month of receiving a valid request.

There is no charge for making a privacy request, except in narrow circumstances permitted by law where a request is manifestly unfounded or excessive.

If you believe Proof has mishandled your personal data, you can complain to the UK Information Commissioner's Office.

You do not need to contact Proof before complaining to the ICO, but we would welcome the opportunity to address your concern.

Proof may update this notice from time to time.

Material changes will be notified by reasonable means, such as a visible website notice, in-product notification or email to registered contributors where appropriate.

The version field at the top of this notice records the current version.

Cookie Notice

This notice explains the cookies and similar storage technologies Proof uses, and the position Proof takes on non-essential tracking.

Essential cookies only. No advertising, no retargeting, no marketing trackers.

Proof's launch position is to use only cookies and similar storage technologies that are necessary for the website and contributor workflows to function.

Proof does not run advertising or marketing analytics. There are no advertising pixels, retargeting tags or third-party behavioural tracking scripts on Proof surfaces.

This position aligns with Proof's wider commitments: no advertising on the public ledger, no paid placement, no product leaderboards, and no monetisation of farmer or contributor identity.

Small files and storage entries set by the website.

A cookie is a small file stored on your device by a website. Similar technologies include local storage, session storage and other small browser storage entries.

These technologies allow a website to remember information about your session, your preferences or the way you have interacted with the service.

UK cookie rules apply to cookies and to similar technologies that store information on, or access information from, a user's device.

The cookies needed for the service to work.

These cookies are necessary for the Proof website, contributor accounts and security controls to function. They are not used for advertising or cross-context tracking.

What Proof does not use at launch.

Proof does not currently use:

• ·advertising cookies;
• ·retargeting cookies;
• ·behavioural profiling cookies;
• ·ad network tags;
• ·Meta pixel;
• ·Google Ads tag;
• ·LinkedIn Insight tag;
• ·TikTok pixel;
• ·third-party social media widgets that set tracking cookies;
• ·heatmap or session replay cookies.

Proof does not currently run web analytics on the public website.

If Proof later adds any non-essential cookie or analytics technology, it will be disclosed in this notice and consent controls will be provided before the relevant non-essential cookie is set.

Because Proof uses essential cookies only at launch, there is no non-essential cookie consent panel to manage.

You can manage cookies through your browser. Browsers allow you to block cookies, block third-party cookies, clear stored cookies, or receive prompts before cookies are set.

Blocking essential cookies may prevent the contributor Workbench, login, saved work, security controls or other authenticated parts of Proof from functioning.

Proof may update this notice from time to time.

Material changes — especially the addition of any non-essential cookie or analytics technology — will be disclosed in this notice and, where required, through a consent control before the relevant cookie is set.

Website Terms of Use

These terms govern use of the Proof website and public Proof content.

Contributor accounts, the contributor Workbench and commercial access to Proof data are governed by the Contributor Terms and Commercial Terms in addition to these Website Terms.

These terms apply when you visit the Proof website at proof.ag, including any subdomains, and when you read or interact with public Proof Records, the Records Explorer, the Trust Model, Data & Privacy pages or other public Proof content.

By using the website, you agree to these terms.

If you do not agree, please do not use the website.

Proof is operated by PROOF AG LTD, a company registered in England and Wales with company number 17211914.

Proof is building permanent public evidence infrastructure for agriculture. Public Proof Records describe what was tested in real fields, under stated conditions, with stated evidence and stated limits.

Proof Records are evidence descriptions. They are not product endorsements, product rankings, agronomic recommendations, regulatory approvals or guarantees of future performance.

You may use the Proof website to:

• ·read public Proof Records and public redacted projections;
• ·search public records through the Records Explorer;
• ·understand the Trust Model and public/private boundary;
• ·apply to contribute records;
• ·make commercial, research, press, support, legal or privacy enquiries;
• ·cite public Proof Records in accordance with these terms.

You must use the website lawfully, responsibly and in a way that does not compromise the public ledger, contributors, farms, private data or Proof's service.

Public Proof Records describe what was recorded under stated conditions, in a structured format. They may include:

• ·crop, season, broad region and soil class;
• ·product category and treatment/control design;
• ·application timing and method;
• ·outcome and measurement method;
• ·evidence manifest;
• ·conflict declarations;
• ·addenda;
• ·Evidence Query state;
• ·schema version;
• ·canonical hash.

Public Proof Records do not contain exact farm or field identity by default. Exact farm data, raw evidence files and private record material sit in the private envelope.

Public Proof Records are intended to be permanent. Corrections happen through addenda, redaction updates and Evidence Queries — not silent deletion or quiet rewriting.

Proof does not provide agronomic advice.

Proof Records describe what was recorded under stated conditions. They are not:

• ·product recommendations;
• ·agronomic instructions;
• ·regulatory approvals;
• ·product rankings;
• ·"best product" lists;
• ·guarantees of performance;
• ·statements that a product will perform the same way in another crop, soil, region, season or system.

You should not rely on Proof content as the sole basis for a decision affecting a farm business. Decisions about product choice, application, treatment, crop management, trial design or regulatory compliance require qualified professional advice for your specific conditions.

A recorded outcome is not a product verdict.

Public Proof Records are intended to be citable and inspectable.

You may cite a public Proof Record by using its UID, public URL and canonical hash, provided you do not misrepresent the record's meaning, evidence state, outcome, scope, conflicts or limits.

When citing a Proof Record, you should cite:

• ·the record UID;
• ·the public URL;
• ·the canonical hash where available;
• ·the evidence state;
• ·the date accessed where relevant.

You must not use a Proof Record to imply a broader product claim than the record supports.

The Proof name, brand, website design, page content, software, interface, copy, data structures and other Proof-created materials are owned by PROOF AG LTD or its licensors.

Public Proof Records and public redacted projections may be read, cited, linked to and quoted in short attributed extracts for academic, regulatory, journalistic, research and professional discussion purposes, provided that you:

• ·cite the relevant record by UID and public URL;
• ·do not misrepresent the record;
• ·do not remove context, conflicts, addenda or Evidence Query state;
• ·do not use the record as a general product endorsement;
• ·do not scrape, bulk-download or republish the public ledger except through access Proof has expressly provided.

Bulk access, commercial analytics, API access, commercial publication, commercial reuse and structured export are governed by separate Commercial Terms.

You may use the Proof website for reasonable, good-faith purposes that are consistent with these terms.

You must not interfere with the operation, security, availability, integrity or privacy commitments of Proof.

You must not:

1. 01use the website or its content in a way that violates applicable law;
2. 02scrape, crawl, mass-download, harvest or otherwise extract public record content except through structured access Proof has expressly provided;
3. 03attempt to re-identify farms, fields, contributors or private parties behind public redacted projections;
4. 04combine Proof data with external datasets for the purpose of defeating redaction or identifying farms or fields;
5. 05misrepresent Proof Records as product endorsements, product rankings, agronomic advice, regulatory approvals or guarantees of performance;
6. 06use Proof content to make general product claims that the underlying records do not support;
7. 07remove or hide conflict labels, Evidence Query status, addenda, redaction notes or record limitations when quoting or referencing Proof content;
8. 08submit false evidence, falsify contributor identity or compromise the integrity of the ledger;
9. 09interfere with the security or operation of Proof, attempt unauthorised access, probe for vulnerabilities outside any published responsible-disclosure programme, or bypass technical controls;
10. 10use Proof content for unsolicited marketing, harassment, intimidation, targeting of farmers or contributors, or any purpose intended to harm contributors, farms or third parties;
11. 11use Proof public content to build a competing database through automated extraction without permission;
12. 12use Proof content for paid placement, product ranking, advertising or endorsement claims not authorised by Proof.

Particular emphasis is placed on the prohibition against re-identification of farms or fields behind redacted public projections. This is a core Proof commitment to contributors and farm clients. Attempts to defeat that commitment are taken seriously.

The website may contain links to third-party websites.

Those links are provided for convenience and context. They do not constitute endorsement by Proof.

Proof is not responsible for the content, accuracy, availability, security or privacy practices of third-party websites.

Proof aims to keep the website available, but does not guarantee uninterrupted availability.

Proof may change, update, suspend or withdraw parts of the website from time to time.

Proof may revise these terms. Material revisions will be notified by reasonable means. Continued use of the website after revised terms take effect means you accept the revised terms.

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot be excluded under English law.

To the fullest extent permitted by law, Proof is not liable for:

• ·loss of profit;
• ·loss of revenue;
• ·loss of business;
• ·loss of goodwill;
• ·loss of data;
• ·indirect or consequential loss;
• ·loss arising from reliance on Proof content as agronomic advice;
• ·loss arising from product, crop, treatment or farm management decisions made using Proof content without appropriate professional advice.

Proof Records are evidence descriptions, not recommendations. Decisions taken in reliance on Proof content are at the user's own risk and should be supported by qualified professional advice.

These terms are governed by the laws of England and Wales.

Disputes arising from these terms are subject to the courts of England and Wales, subject to any non-waivable consumer rights that may apply.

For the plain-English explanation of how Proof handles public records, private envelopes and farm data, see /data-and-privacy.

For the structural rules of the ledger, see the Trust Model.

Contributor Terms

These terms apply to people and organisations who apply to contribute, create drafts, upload evidence, manage farms or records, lock records, respond to Evidence Queries or otherwise participate in Proof contributor workflows.

These Contributor Terms apply in addition to the Website Terms and Privacy Notice.

By applying for, accessing or using a contributor account, you agree to these Contributor Terms.

If you contribute on behalf of an organisation, farm, client or research body, you confirm that you have authority to do so.

Proof may require contributors to provide information about their identity, professional context, organisation, role, farm authority and evidence activity.

Proof may accept, refuse, suspend or remove contributor access where necessary to protect the integrity of the public ledger, the privacy of farms, contributors or clients, or the security of the service.

Contributor access is a privilege attached to accountability. It is not an automatic right.

Proof may describe contributors by status, role or attribution mode. Public contributor status supports accountability and eligibility. It is not a claim that every record produced by that contributor is true.

A verified or credentialed contributor is a contributor whose identity, professional context or authority has been checked to the level Proof requires for the relevant workflow.

The record still stands on its own evidence.

You must only create, manage or lock records for farms, fields, organisations or clients where you have authority to do so.

Authority may come from:

• ·your own farm business role;
• ·an agronomist-client relationship;
• ·a research agreement;
• ·a trial agreement;
• ·an organisation membership;
• ·a recorded Proof access grant;
• ·another documented authorisation accepted by Proof.

You must not upload exact farm data, raw evidence or private client material unless you have authority to do so.

Revoking access stops future work where the revocation applies. It does not erase locked public Proof Records that were lawfully created before revocation.

Draft records are mutable. Locked records are not.

You are responsible for taking reasonable care that the information you enter into a draft record is accurate, complete and not misleading.

You must not knowingly submit false evidence, misstate a control arm, hide a material conflict, fabricate a protocol, backdate a methodology, falsify a contributor identity, or otherwise compromise the integrity of a record.

Proof may run validation checks before a record can be locked.

Validation is structural. It does not mean Proof has proven that the product works, that the outcome is correct, or that the record is scientifically conclusive.

Every locked Proof Record produces a public redacted projection.

By locking a record, you authorise Proof to publish and maintain the public redacted projection of that record.

The public projection may include:

• ·crop;
• ·season;
• ·broad region;
• ·soil class;
• ·product category;
• ·treatment/control structure;
• ·application timing and method;
• ·outcome;
• ·evidence manifest;
• ·conflict declarations;
• ·addenda;
• ·Evidence Query state;
• ·schema version;
• ·canonical hash.

The public projection does not include exact farm identity or raw evidence files by default.

Locked public records are intended to be permanent. Corrections, clarifications and privacy updates happen through addenda, redaction updates and Evidence Queries, not silent deletion.

Private envelope data may include exact farm identity, exact field references, field boundaries, raw GPS data, EXIF metadata, raw evidence files, private notes, invoices, unredacted lab reports and sensitive commercial material.

You must handle private envelope data carefully.

You must not upload private envelope data unless you have authority to do so.

You must not mark evidence or derivatives as public unless the material is appropriate for public display and does not expose private farm, client or commercially sensitive information.

Proof may block, delay, redact or remove public display of material where it reasonably believes publication could expose private data, breach these terms, create legal risk or compromise a farm or contributor.

Evidence is more than file storage. Evidence items must be linked to the part of the record they support.

When you upload evidence, you confirm that:

• ·you have authority to upload it;
• ·the evidence is not knowingly false or misleading;
• ·the evidence does not unlawfully infringe third-party rights;
• ·the evidence does not contain material that should not be uploaded;
• ·any public visibility setting is accurate and appropriate;
• ·you understand raw evidence is private by default.

Proof may process evidence to generate metadata, hashes, redacted derivatives, previews and public manifest entries.

You must declare material conflicts and affiliations connected to a record.

These may include:

• ·manufacturer employment or consultancy;
• ·product sponsorship;
• ·free or discounted product supply;
• ·distributor or reseller relationships;
• ·sales commission or commercial incentive;
• ·research funding;
• ·family or business relationships;
• ·other material interests that could affect how a reader interprets the record.

A declared conflict changes interpretation. It does not automatically invalidate a record.

A hidden conflict is a record integrity issue.

Locked records do not silently change.

Corrections, clarifications and additional evidence after lock must be added through addenda or other Proof-supported append-only processes.

Evidence Queries are structured questions about a record. They are not comment threads, product debates or general complaints.

If an Evidence Query is raised on a record you contributed to, you may be required to respond, clarify, add evidence, post an addendum or accept that the record should carry a qualification.

Proof may moderate, close, merge, reject or escalate Evidence Queries where necessary to protect the integrity of the process.

Individual contributors can create, view and export their own records in accordance with Proof's available product features and these terms.

Export rights do not override privacy, farm authority, third-party confidentiality, legal retention or public record integrity.

Proof may limit, delay or refuse an export where it would expose data the requester is not authorised to receive.

Proof may suspend, restrict or terminate contributor access where it reasonably believes that a contributor has:

• ·submitted false or misleading evidence;
• ·hidden a material conflict;
• ·attempted to expose private farm data;
• ·attempted to re-identify farms from public projections;
• ·breached farm authority or access permissions;
• ·uploaded unlawful or unauthorised material;
• ·misused Evidence Queries;
• ·attempted to manipulate public records;
• ·breached these terms or the Website Terms.

Account action does not erase locked public records. Public record corrections are handled through the record history.

You retain your rights in material you upload, subject to any rights held by farms, clients, organisations or third parties.

You grant Proof the rights needed to operate the service, including rights to:

• ·store and process draft records;
• ·process and hash evidence;
• ·create public redacted projections;
• ·publish locked public Proof Records;
• ·maintain record history;
• ·generate addenda, Evidence Query displays and record metadata;
• ·provide authorised exports and Client Evidence Packs;
• ·operate security, audit and integrity controls.

For private envelope material, this licence is limited to operating Proof and providing authorised services. It does not permit Proof to sell private envelope data to commercial customers.

Proof may update these Contributor Terms from time to time.

Material changes will be notified by reasonable means. Continued use of contributor services after revised terms take effect means you accept the revised terms.

Where a change materially affects contributor rights, Proof will take reasonable steps to bring the change to the attention of affected contributors.

Commercial Terms

These Commercial Terms provide the framework for commercial access to Proof. Specific commercial services may be governed by an order form, statement of work, data agreement, API agreement, research agreement or other written agreement.

Commercial access sits above the public record. It does not change the record layer.

Proof may provide commercial services including:

• ·attestation references;
• ·analytics;
• ·cohort queries;
• ·infrastructure and API access;
• ·research partnerships;
• ·data partnerships;
• ·integration work;
• ·reporting tools;
• ·assurance or supply-chain workflows.

Each commercial engagement is scoped separately.

Companies pay for depth, integration, attestation and partnership.

They cannot pay to control, suppress, rewrite, rank or hide the evidence.

Commercial access does not:

• ·suppress records;
• ·remove records;
• ·rewrite locked records;
• ·hide conflicts;
• ·create paid product rankings;
• ·create paid placement;
• ·create advertising inventory;
• ·give access to private envelope data without authorisation;
• ·allow control over public evidence.

If a commercial product would compromise these limits, the product is not built.

The Proof Recorded mark, where available, indicates that a product, trial, claim or reference appears in one or more locked Proof Records.

It does not mean Proof endorses the product.

It does not mean the product works generally.

It does not mean the product will produce the same outcome in other crops, soils, seasons or regions.

Any commercial use of a Proof mark must follow Proof's usage rules and the scope of the relevant commercial agreement.

Commercial analytics may provide structured access to public redacted records, cohort summaries, filters, dashboards or exports.

Commercial analytics operate on the public record layer unless a separate written agreement and recorded authorisation permit additional access.

Cohort outputs must respect Proof's privacy thresholds and redaction commitments.

Proof does not provide commercial product leaderboards, paid "best product" lists or paid outcome rankings.

API and infrastructure access are provided only under a written commercial agreement.

Commercial API access may be rate-limited, scoped, monitored and restricted.

API access does not permit:

• ·scraping beyond agreed limits;
• ·re-identification attempts;
• ·private envelope access without authorisation;
• ·republication of public records without required context;
• ·removal of conflicts, addenda, Evidence Query state or record limitations;
• ·use of Proof data for unauthorised product claims.

The private envelope is not part of standard commercial access.

Private envelope data includes exact farm identity, field boundaries, raw GPS, raw evidence files, EXIF metadata, private notes, invoices, unredacted lab reports and sensitive commercial material.

A commercial customer receives private envelope data only where explicit recorded authorisation exists from the relevant authorised party and the commercial agreement permits that access.

Paying Proof does not create private data access.

Permitted commercial use depends on the written scope of the engagement.

It may include:

• ·cohort analysis of public redacted records;
• ·authorised reports;
• ·attestation references;
• ·API access to public record data;
• ·structured exports;
• ·research collaboration;
• ·integration into assurance or supply-chain workflows;
• ·reference to specific Proof Records in commercial documents.

All permitted commercial use must preserve the record's UID, context, evidence state, conflicts, addenda, Evidence Query state and limitations.

Commercial users must not:

1. 01use Proof data to suppress, hide or attack records;
2. 02pay for placement, ranking or favourable display;
3. 03imply Proof endorsement where none has been granted;
4. 04make general product claims not supported by the cited records;
5. 05remove conflict labels, qualifications, addenda or Evidence Query state;
6. 06attempt to identify farms, fields or contributors behind redacted public projections;
7. 07combine Proof data with other datasets for re-identification purposes;
8. 08resell Proof data except where expressly permitted in writing;
9. 09use Proof content for advertising without written permission;
10. 10use Proof content in a way that harms contributors, farmers or third parties;
11. 11interfere with Proof systems, security, rate limits or access controls.

Proof may enter research partnerships with institutions, levy bodies, universities, manufacturers, supply-chain organisations or other parties.

Research partnerships must respect:

• ·public/private separation;
• ·contributor and farm authority;
• ·redaction;
• ·conflict declarations;
• ·record integrity;
• ·applicable data protection law;
• ·the Trust Model.

Research outputs must not turn individual Proof Records into claims they do not support.

Fees, deliverables, usage limits, timelines, support levels, data scope, confidentiality obligations and termination rights are set out in the relevant commercial agreement.

If there is a conflict between these Commercial Terms and a signed commercial agreement, the signed commercial agreement controls for that engagement, unless it would compromise Proof's non-negotiable public record and private envelope commitments.

Proof may suspend or terminate commercial access where a customer breaches these terms, breaches an engagement document, creates security risk, misuses data, attempts re-identification, misrepresents Proof Records or compromises the public/private boundary.

Suspension or termination of commercial access does not remove public Proof Records.

Proof may update these Commercial Terms from time to time.

Commercial agreements may specify how changes apply to an existing engagement. Where no specific agreement applies, continued use of commercial access after revised terms take effect means the revised terms apply.
