Website Terms of Use

These terms govern your use of proof.ag and the public website services provided by PROOF AG LTD.

Please read them before using the website.

By using proof.ag, you agree to these terms.

If you do not agree to them, you should not use the website.

Separate terms apply to Proof Records, contributor accounts, commercial services and other Proof products where those services are used.

1. Who we are

proof.ag is operated by:

PROOF AG LTD
A private limited company registered in England and Wales.
Company number: 17211914

Registered office:
Grosvenor House
11 St Pauls Square
Birmingham
England
B3 1RB

ICO registration reference: ZC145363

Email: ct@proof.ag

In these terms, “Proof”, “we”, “us” and “our” mean PROOF AG LTD.

2. What these terms cover

These terms apply to:

• proof.ag;
• its public pages;
• public written content;
• illustrative Proof Record examples;
• interactive demonstrations made available through the website;
• public downloadable material unless separate terms are stated;
• Contact and Careers pages;
• published Proof findings and public redacted views of Proof Records when those become available.

These terms do not govern:

• production Proof Records;
• contributor accounts;
• Proof Accredited Contributor status;
• commercial Proof services;
• Proof Network programmes;
• Proof Intelligence;
• Proof Recorded licences;
• Proof Attestations;
• APIs or integrations.

Where those services are used, they are subject to their relevant terms and agreements.

3. Current website status

Proof is currently pre-launch.

The website may show:

• a working interactive demo;
• illustrative Proof Records;
• synthetic or demonstration data;
• example group evidence;
• prototype workflows;
• proposed or developing product functionality.

Unless a page clearly states otherwise, illustrative content is not:

• a live farm record;
• customer evidence;
• real customer activity;
• production platform data;
• a validated commercial outcome;
• evidence of adoption;
• evidence of revenue;
• evidence that a product or practice works.

Illustrative Proof Records must be clearly labelled:

Do not rely on illustrative material as if it were real agricultural evidence.

4. Proof provides evidence infrastructure, not advice

The website is provided for general information about Proof, its approach to agricultural evidence and its developing products.

Nothing on proof.ag constitutes:

• agronomic advice;
• crop-management advice;
• product recommendation;
• scientific or statistical advice for a particular decision;
• investment advice;
• financial advice;
• lending advice;
• insurance advice;
• legal advice;
• regulatory advice;
• compliance advice;
• certification;
• an assurance decision;
• a guarantee of an agricultural outcome.

Proof may present:

• recorded information;
• observations;
• measurements;
• derived calculations;
• comparisons;
• methods;
• limitations;
• contextual evidence.

The meaning, interpretation and decision made from that evidence remain the responsibility of the relevant user and, where appropriate, their professional advisers.

Proof does not rank products, farms, advisers or farming systems through the public website.

5. No guarantee that evidence proves causation

Agricultural evidence can arise from:

• field observations;
• commercial practice;
• machinery;
• laboratory testing;
• farm comparisons;
• demonstrations;
• formal trials;
• historical records;
• third-party sources.

Different evidence designs support different conclusions.

A recorded association or observed outcome does not necessarily mean that one action caused another.

Unless expressly stated with an appropriate method and qualification, website content should not be understood as establishing:

• causation;
• efficacy;
• universal applicability;
• statistical representativeness;
• regulatory compliance;
• safety;
• commercial value.

Where Proof uses words such as “verified”, “validated”, “independent” or “representative”, the relevant page should explain what was checked and what the term means in that context.

6. Accuracy and availability of website information

We take reasonable care over the information published on proof.ag.

However:

• website information may change;
• developing product descriptions may evolve;
• illustrative material may simplify a future workflow;
• external information may become outdated;
• errors may occur;
• content may be incomplete.

We do not promise that every page will always be:

• accurate;
• complete;
• current;
• uninterrupted;
• free from errors.

Where we become aware of a material error, we may correct the website.

This does not allow Proof to silently rewrite the history of a published Proof Record where the Proof Record Rules require an addendum or other visible correction mechanism.

7. Website availability

We may:

• update the website;
• change its structure;
• add or remove features;
• suspend parts of it;
• restrict access;
• withdraw a demonstration;
• carry out maintenance;
• change URLs.

We do not guarantee that proof.ag or any particular page will always be available.

We may restrict access where reasonably necessary for:

• security;
• privacy;
• legal compliance;
• maintenance;
• abuse prevention;
• protection of Proof Records;
• protection of third-party rights.

8. Accounts and restricted demonstrations

Some demonstrations or materials may be made available only to invited or authorised users.

If Proof gives you login details, an access link or another restricted-access method:

• it is for the authorised recipient only;
• you must keep it confidential;
• you must not share it without permission;
• you must not attempt to expand the access granted;
• you must notify Proof if you believe access has been compromised.

Restricted demo access does not give you permission to:

• access production systems;
• inspect private data;
• circumvent technical restrictions;
• access information belonging to another user;
• test vulnerabilities outside an agreed security-testing process.

Proof may withdraw restricted access at any time.

9. Acceptable use

You may use proof.ag for lawful purposes, including:

• learning about Proof;
• evaluating whether Proof may be relevant to you or your organisation;
• contacting Proof;
• applying for a role;
• viewing material that has been intentionally made public;
• sharing ordinary links to public Proof pages;
• citing public Proof material in accordance with these terms.

You must use the website responsibly and lawfully.

10. Prohibited use

You must not use proof.ag to:

• break any applicable law;
• commit or facilitate fraud;
• impersonate another person or organisation;
• submit deliberately false authority or identity information;
• introduce malware or malicious code;
• interfere with the operation of the website;
• overload or disrupt the service;
• bypass authentication or security controls;
• access data without authorisation;
• probe restricted systems without written permission;
• attempt to obtain credentials belonging to another person;
• use a vulnerability to access information beyond what is necessary to report it;
• interfere with a Proof Record or audit history without authority.

Unauthorised access to computer material may also engage the Computer Misuse Act 1990.

12. Automated access and scraping

You must not use automated systems to access proof.ag in a way that:

• circumvents access controls;
• ignores technical restrictions;
• imposes an unreasonable load;
• extracts restricted or private information;
• attempts re-identification;
• reconstructs a protected dataset;
• copies the site at scale for a competing evidence service;
• interferes with normal operation.

This includes:

• bots;
• crawlers;
• scrapers;
• automated agents;
• bulk-download tools;
• automated query systems.

Ordinary search-engine indexing may take place where it respects:

• robots.txt;
• published crawler rules;
• authentication boundaries;
• rate limits;
• other technical controls.

Proof may block automated access that is abusive, unsafe or inconsistent with these terms.

13. AI and model training

Public availability does not give permission to copy Proof’s website, taxonomy, record structures, protected datasets or other substantial content at scale for:

• training a machine-learning model;
• creating a competing agricultural evidence product;
• reproducing the Proof recording standard;
• building a substitute database;
• systematic extraction of Proof Records.

Where you want to use Proof material for research, machine learning, model evaluation or automated analysis beyond ordinary website use, contact Proof for written permission.

Nothing in this clause restricts a right that applicable law expressly gives you and which cannot lawfully be excluded.

14. Intellectual property

Unless otherwise stated, intellectual-property rights in proof.ag and its original content belong to PROOF AG LTD or its licensors.

This may include rights in:

• text;
• designs;
• graphics;
• user interfaces;
• product presentation;
• website code;
• diagrams;
• documentation;
• taxonomies;
• schemas;
• identifiers;
• methodologies;
• trade marks;
• logos;
• Proof Record presentation;
• Proof product names.

“Proof”, the Proof logo, “Proof Recorded” and other Proof names or marks may not be used in a way that:

• suggests endorsement;
• suggests accreditation;
• suggests certification;
• suggests partnership;
• causes confusion about the source of a product or service.

No intellectual-property right is transferred to you merely because you can view material on the website.

15. Permitted copying

You may:

• print or save reasonable extracts for your own internal reference;
• quote short passages with appropriate attribution;
• link to public Proof pages;
• cite a published Proof output where it is intended to be publicly citable.

You must not:

• reproduce substantial parts of the website commercially without permission;
• remove copyright, attribution or provenance notices;
• present Proof material as your own;
• materially alter a Proof citation in a way that changes its meaning;
• copy public content in a way that falsely implies endorsement;
• use Proof branding outside the permissions given.

Where third-party material is identified, separate rights may apply.

16. Linking to Proof

You may link to public pages on proof.ag provided that the link:

• is lawful;
• is accurate;
• does not imply a relationship that does not exist;
• does not misrepresent Proof;
• does not frame Proof content in a misleading context.

You must not state or imply that Proof:

• endorses your organisation;
• endorses a product;
• endorses an agronomic recommendation;
• certifies an outcome;
• approves a claim;

unless Proof has expressly authorised that statement.

Proof may request removal of a misleading or abusive link.

17. Citations of published Proof outputs

The standard public output of Proof is an aggregate or cohort finding, produced under the applicable permissions and privacy protections.

A public redacted view of an individual Proof Record exists only where that publication has been deliberately created, reviewed and permissioned. Locking a record does not publish it.

When published Proof outputs become available, they may be designed to remain citable over time.

Where you cite one, you should preserve:

• the output or Proof Record ID;
• the relevant version or date where provided;
• the status;
• material limitations;
• any visible addendum relevant to the point being cited.

You must not knowingly cite an earlier state in a way that conceals a later correction, dispute or removal notice.

A citation to a published Proof output does not mean Proof endorses the interpretation you place on it.

18. Proof Recorded and other status marks

You must not use:

• Proof Recorded;
• Proof Accredited;
• a Proof Attestation;
• a Proof credential;
• any similar Proof status or mark;

unless the relevant status genuinely applies and you have permission to use the mark where permission is required.

Payment does not itself create any of these statuses.

A status may be restricted, suspended or withdrawn in accordance with the relevant rules.

Do not use a Proof mark in a way that suggests:

• certification;
• product efficacy;
• regulatory approval;
• universal validation;
• recommendation;

unless that meaning is expressly authorised under a separate applicable Proof rule.

19. Information you send through the website

When you submit information through:

• Contact;
• Careers;
• email;
• another public website form;

you confirm that:

• you are entitled to provide it;
• it is not deliberately false or unlawful;
• its submission does not knowingly infringe another person’s rights.

Do not submit through a general public form:

• passwords;
• identity documents;
• raw private farm records;
• exact field boundaries;
• confidential commercial documents;
• sensitive evidence;
• special-category personal information;

unless Proof specifically asks for it through an appropriate process.

Personal information is handled in accordance with the relevantPrivacy Notice.

20. Feedback and ideas

You are welcome to give Proof feedback about the website, demo or product.

Unless Proof has agreed otherwise in writing:

• ordinary feedback is not confidential;
• Proof may consider and use ideas, suggestions or observations without an obligation to develop them;
• submitting feedback does not make you an inventor, partner, employee or owner of Proof’s resulting product.

This clause does not transfer ownership of material that you already own.

If you need information to be treated as confidential, agree that with Proof before providing it.

21. Third-party websites and services

proof.ag may link to websites or services operated by other organisations.

A link does not automatically mean that Proof:

• endorses the organisation;
• endorses its product;
• agrees with its content;
• controls its privacy or security practices.

Third-party websites are governed by their own terms and privacy practices.

Proof is not responsible for third-party content merely because it is linked from proof.ag.

22. Security

We take reasonable steps to protect proof.ag.

You are responsible for protecting:

• your own device;
• browser;
• network;
• passwords;
• authentication credentials.

If you discover a suspected vulnerability, privacy failure or access-control problem, use /legal/security.

Do not:

• exploit it;
• access unnecessary information;
• retain private information obtained accidentally;
• publicly disclose the vulnerability before responsible investigation is possible.

A good-faith security report made in accordance with the Security and Responsible Disclosure Policy will be handled under that policy.

23. Viruses and malicious software

We take reasonable measures to operate the website securely, but we cannot guarantee that every online service will always be completely free from:

• bugs;
• malware;
• vulnerabilities;
• harmful third-party activity.

You should use appropriate security protection on your own systems.

You must not knowingly introduce malicious software into Proof systems.

24. Liability

Nothing in these terms excludes or limits liability where it would be unlawful to do so.

In particular, nothing excludes liability for:

• death or personal injury caused by negligence;
• fraud;
• fraudulent misrepresentation;
• another liability that cannot legally be excluded or limited.

If you use Proof for business purposes

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

• loss of profit;
• loss of revenue;
• loss of business;
• loss of anticipated savings;
• loss of goodwill;
• loss of business opportunity;
• indirect or consequential loss;

arising from ordinary use of, or inability to use, the public website.

You are responsible for obtaining professional advice before making agronomic, commercial, lending, insurance, regulatory or other consequential decisions based on website information.

These website terms do not limit liability under a separate signed commercial agreement where that agreement provides otherwise.

If you are a consumer

Nothing in these terms affects your statutory consumer rights.

Proof is responsible for losses that are a foreseeable result of its breach of these terms or failure to use reasonable care and skill where the law requires that responsibility.

Proof is not responsible to a consumer for business losses arising from use connected with a trade, business, craft or profession.

25. No reliance on future product statements

The website may describe:

• intended functionality;
• future products;
• product concepts;
• planned integrations;
• developing services.

These are descriptions of direction, not contractual commitments, unless incorporated into a separate written agreement.

Proof may change:

• product scope;
• names;
• design;
• sequencing;
• launch dates;
• functionality;

as the platform develops.

Nothing on the public website guarantees that a proposed product or feature will launch.

26. Changes to these terms

Proof may update these terms where necessary to reflect:

• changes to the website;
• changes to law;
• security requirements;
• new public functionality;
• changes to how published Proof outputs or public redacted views operate.

The current version will show:

• version number;
• effective date;
• last-reviewed date.

Previous versions will be available at /legal/archive.

Where a material change affects a restricted or account-based service, Proof will provide appropriate notice where required.

A change to these Website Terms does not retrospectively widen a Proof Record permission.

27. Suspension and enforcement

Proof may restrict or suspend access where it reasonably believes that a user has:

• breached these terms;
• attempted unauthorised access;
• attempted re-identification;
• misused Proof branding;
• interfered with service security;
• misrepresented Proof evidence or status;
• created a material risk to another person or organisation.

Where appropriate, Proof may also:

• preserve relevant logs;
• investigate the activity;
• notify an affected party;
• report unlawful activity to a competent authority;
• seek legal remedies.

28. Severability

If a court or competent authority finds part of these terms unlawful or unenforceable, the remaining provisions continue to apply to the extent permitted by law.

29. No waiver

If Proof does not immediately enforce a provision of these terms, that does not mean it has permanently given up the right to enforce it.

30. No third-party rights

Unless these terms expressly state otherwise, a person who is not a party to these terms has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce them.

This does not affect any right or remedy that exists independently of that Act.

31. Governing law and courts

Business users

These terms and any non-contractual dispute relating to them are governed by the law of England and Wales.

The courts of England and Wales have exclusive jurisdiction over disputes involving business users, unless Proof and the relevant party have agreed otherwise in writing.

Consumers

These terms are governed by the law of England and Wales, subject to any mandatory protections that apply to you.

Nothing in these terms removes a right you may have under applicable consumer law to bring proceedings in another court with jurisdiction over the dispute.
