Terms of service

Last updated: 15 July 2026

1. These terms, in plain English

This is the agreement between you (and any organisation you act for) and plaingraph OÜ ("plaingraph", "we", "us") for use of the plaingraph service. By signing up, signing in, or using the service or its APIs, you agree to these terms. If you are agreeing on behalf of a company, you confirm you are allowed to bind it. If you do not agree, please do not use the service.

2. What plaingraph does

plaingraph turns public company-registry records and filed accounts into clean, machine-readable company fundamentals — financials, implied valuation, charges, filing-compliance signals, and corporate group structure — designed to be used by developers and AI agents through a hosted MCP server or a REST API. The service may not be reliable, complete, or available at any given time.

3. The service: subscriptions, trial, and changes

Paid subscription plans are set out on our pricing page. Payments are handled by Lemon Squeezy as merchant of record; the fees, plan limits, and any trial terms shown at checkout and on the pricing page form part of this agreement. A trial, where offered, requires a payment method and converts to a paid subscription unless you cancel before it ends. You can cancel at any time; the service is provided "as is", and:

• we make no promise about uptime, performance, or support;
• features, endpoints, data coverage, and limits can change or be removed at any time, with or without notice;
• we may suspend or end the service, or your access to it, at any time; and
• you should not rely on the service as your only source for any decision that matters.

The service carries no service-level agreement by default. If we offer a service-level commitment — for example a target availability or support response — for a particular plan, it will be stated separately and in writing; absent that, uptime, support, and performance are provided on a reasonable-efforts basis only.

4. Results are evidence, not advice

Some outputs are derived and probabilistic — for example an implied valuation, a governance hygiene score, or an "overdue" filing flag. These carry a confidence or coverage signal and the source they were derived from; they are estimates built from public records, not financial, investment, credit, or compliance advice. You are responsible for any decision you make, and for reviewing the underlying evidence and source before you act. plaingraph does not "verify", "clear", or "approve" any company. Registry and accounts data can be out of date, incomplete, or wrong at source, and we do not guarantee its accuracy.

5. Where the data comes from

The service is built on public sources, including UK Companies House, the Estonian e-Business Register, ESEF filings, the FCA National Storage Mechanism, and GLEIF (the Global Legal Entity Identifier Foundation). Each value carries its source and an as-of timestamp. You agree to use the data in line with those sources' own terms and with the law that applies to you — including data-protection law. We may add or change sources over time.

6. Using the service responsibly

Your use of the service is also governed by our Acceptable Use Policy, which forms part of these terms and covers automated and agent access, prohibited uses, and sanctions and export-control restrictions.

You agree not to:

• break any law that applies to you, including data-protection law;
• use the data to unlawfully profile, harass, or discriminate against any individual, or to make a legally significant decision about someone by automated means alone where the law requires human involvement;
• resell, redistribute, sublicense, or otherwise make the data available to others as a standalone dataset, feed, or data product, or use the service to build, train, or populate a dataset or model that substitutes for or competes with the service;
• scrape, overload, probe, or try to break the service or its security, or get around any limit or access control; or
• misrepresent plaingraph's output as a guarantee or as your own original source data.

You may, though, build on the service. You can incorporate its output into your own applications, products, or services that add material functionality of their own, and make the resulting output available to your end users as an integral part of that service — for example, enriching your own company or portfolio records with plaingraph fundamentals. What you may not do is pass the data through on a standalone basis, or in a form that lets someone extract or re-use it as a substitute for the service itself. You are responsible for your end users' use of anything you build on the service, and where output carries a source attribution (for example the Estonian register, provided under a CC-BY licence), you must preserve that attribution downstream.

You may store and cache the output your plan returns to run your own service — you do not have to re-fetch a value each time you use it. But the data is point-in-time and can be restated at source, so you must not present a stale cached value as current, and you must refresh or expire it within a reasonable period. If we tell you that a value has been suppressed or corrected — for example following a data-protection request (see our privacy policy) — you agree to apply that update in your own copy without undue delay. When your access ends, you must stop using and delete the output you have cached, except where the law requires you to keep it.

Where you submit personal data to the service (for example in what you look up) and we process it on your behalf, our Data Processing Addendum applies and forms part of these terms.

7. Your access and API keys

Keep your sign-in details and API keys secret. You are responsible for everything done with your account or keys. Tell us promptly at [email protected] if you think a key has been exposed, and we will help you rotate it.

8. Who owns what

plaingraph (and its licensors) own the service, the software, and the way we structure, normalise, and present the data. We give you a limited, non-exclusive, non-transferable, non-sublicensable (except to your end users to the extent section 6 allows) right to use the service and its output for your own business while you use the service, including to build the value-added services described in section 6. The underlying public records belong to their original sources. Anything you send us to run the service (your queries) stays yours; we only use it to provide and protect the service, as set out in our privacy policy. If you give us feedback, we may use it freely to improve the service.

9. No warranties

The service is provided "as is" and "as available", with no warranties of any kind. To the fullest extent the law allows, we disclaim all implied warranties — including accuracy, completeness, timeliness, fitness for a particular purpose, title, non-infringement, and uninterrupted or error-free operation. We do not warrant that the data is correct or that the service will meet your needs or any legal or regulatory requirement that applies to you.

10. Limitation of liability

Nothing in these terms limits liability that cannot be limited by law — for example, liability for death or personal injury caused by our negligence, or liability for our own fraud, intent, or gross negligence.

Subject to that, and to the fullest extent the law allows:

• we are not liable for any indirect, incidental, special, or consequential loss, or for any loss of profit, revenue, business, goodwill, data, or anticipated savings, however it arises;
• we are not liable for any decision you make, or fail to make, based on the service's output, including any onboarding, compliance, or risk decision; and
• our total liability to you for all claims arising out of or relating to the service or these terms is limited, in aggregate, to the greater of the fees you paid us for the service in the 12 months before the claim and €100.

11. You cover claims from your misuse

If someone brings a claim against us because you used the service in breach of these terms or the law, you agree to cover the reasonable costs, damages, and expenses we incur from that claim, to the extent it was caused by your breach.

12. Suspension and ending access

You can stop using the service at any time. We may suspend or end your access — or the service as a whole — at any time, especially if you breach these terms or the law, or to protect the service or other users. The sections that by their nature should survive (for example sections 4, 8, 9, 10, 11, and 14) continue to apply after access ends.

13. Changes to these terms

We may update these terms as the service develops. If a change is material, we will give users reasonable notice (for example by email or in the dashboard). Continuing to use the service after a change takes effect means you accept the updated terms.

14. Governing law and disputes

These terms, and any dispute arising out of or relating to them or the service, are governed by the laws of Estonia. The courts of Estonia (Harju County Court as the court of first instance) have jurisdiction, unless mandatory law that protects you as a consumer gives you the right to bring a claim elsewhere. Nothing here affects your mandatory rights under the law that applies to you.

15. General

These terms, together with the pricing page and any plan terms shown at checkout, are the whole agreement between you and plaingraph about the service, and replace anything said before. If any part is found unenforceable, the rest stays in force. If we do not enforce a right straight away, that is not a waiver of it. You may not transfer your rights or obligations under these terms without our consent; we may transfer ours to a group company, or in connection with a merger, acquisition, or sale of assets, on notice to you.
