These terms are the agreement between you and LT Telecom (UAB "LT telekomunikacijos") for the use of Proof Holdings, the verification service at https://proof.holdings and its API ("the Service"). They are written for businesses and developers. If you use the Service as a consumer, the rights your law grants you are not reduced by anything here.
1. Parties and acceptance
The Service is operated by LT Telecom (UAB "LT telekomunikacijos"), a company registered in Lithuania under code 304043870, VAT number LT100009427918, with its registered office at Buivydiškių g. 118, Zujūnai, LT-14162 Vilniaus r., Lithuania ("we", "us"). You accept these terms by creating an account or by using an API key. If you accept on behalf of a company, you confirm you may bind it. If a business asks you to verify something or approve a request through the Service, you are that business's user and not a party to these terms; how your data is handled is in the Privacy Policy.
2. The Service
Proof Holdings verifies that a person or an agent controls a phone number, an email address or a domain, lets the holder of a domain state which published artifacts act for it, and records approvals made by a person. A successful verification issues a signed proof token whose signature anyone can check offline against our published keys; whether it has since been revoked is published by our status endpoints. The proofs we offer today, and those still planned, are listed at proof.holdings/verify and in the documentation.
3. Accounts, API keys and sub-accounts
You are responsible for everything done with your account and your API keys, including keys you bind to a sub-account (called a project in the dashboard). Keep keys secret; rotate a key you believe exposed; tell us at [email protected] if you believe an account has been misused. We may suspend a key or an account that is being used in breach of these terms, and we will tell you why unless the law prevents it. Write to [email protected] to contest a suspension; we restore access once the breach is cured.
4. Acceptable use
You agree to:
- verify only assets you control or are authorised to verify;
- provide accurate information during verification;
- keep API keys and credentials secure;
- comply with the laws that apply to you and to the people you verify.
You may not use the Service to:
- verify assets you do not control, or impersonate another person or organisation;
- commit or facilitate fraud, money laundering or any other crime;
- send approval requests or messages to people you have no lawful basis to contact;
- interfere with the Service, probe or bypass its security, or work around the rate limits of your plan;
- resell access to the Service without our written agreement (branding the messages your own users receive, as your plan allows, is not reselling);
- copy the Service: reverse-engineer, decompile or extract the source of any part of it that is not published as open source; crawl, scrape or bulk-download its pages, documentation, registry or API responses beyond your own account's use; or use the Service, its documentation or its outputs to build, train or improve a service that competes with it.
5. Customer data and the Data Processing Agreement
When you send us an identifier belonging to one of your users — a phone number, an email address, a domain — you are the controller of that personal data and we process it on your behalf. Our Data Processing Agreement is part of these terms and governs that processing. If these terms and the Data Processing Agreement conflict on a matter of data protection, the Data Processing Agreement prevails. You confirm that you have a lawful basis for the identifiers you send and for the messages the Service delivers to the people behind them. The categories of third parties we use are published at proof.holdings/subprocessors.
Our own processing of your account data as a controller is described in the Privacy Policy.
6. Proof tokens
A proof token is a signed statement that a verification succeeded at a point in time, under the conditions stated in it. It carries a hash of the identifier, not the identifier. Tokens expire and can be revoked; a token is not a permanent statement of control, and a verified result does not say anything about the person's identity beyond what the token states. You are responsible for how you rely on a token.
7. Fees and payment
The pay-as-you-go plan, its free monthly allowance, and the paid plans are described on the pricing page. Paid plans are charged in advance for each billing period. Usage above what your plan includes is deducted from a prepaid balance you buy in the dashboard, at the prices published there; when the balance is used up, new proof requests pause until you top it up. Post-paid invoicing, where usage is charged on an invoice after the billing period, is available only under a separate written agreement and is enabled for your account by us. Prices exclude VAT where it applies. We may change prices with 30 days' notice; the change applies from your next billing period. If a payment fails we may limit the Service until it is settled.
8. Availability and support
We run the Service with care but do not promise uninterrupted availability, and these terms contain no service-level commitment. We publish service status at status.proof.holdings and announce planned maintenance there when we can. Support is by email at [email protected].
9. Intellectual property
The Service, its software, documentation, design and brand belong to us or our licensors; the parts we publish as open source are licensed under the terms stated in each package. You receive a non-exclusive, non-transferable right to use the Service under these terms, and nothing here transfers any of our intellectual property to you. You keep all rights in the data you send us and in what you build on the Service. You may use our name and logo only as the brand kit allows, and you may not present a product of your own as ours or as endorsed by us.
10. Confidentiality
Each side keeps the other's non-public information confidential and uses it only for this agreement. This does not cover information that is public, that the receiving side already knew or developed on its own, or that the law requires to be disclosed.
11. Warranties
The Service is provided as is. We do not warrant that it will be error-free or meet every requirement you have. Nothing in these terms excludes a warranty that cannot be excluded by law.
12. Liability
To the extent the law allows, neither side is liable to the other for indirect or consequential loss, loss of profit, or loss of data. Our total liability under this agreement, for all claims together, is limited to the fees you paid us in the three months before the event giving rise to the claim. These limits do not apply to liability for intentional misconduct or gross negligence, for breach of the confidentiality clause, or for anything else that cannot be limited under the law that governs this agreement.
13. Term and termination
This agreement lasts while you have an account. You may end it at any time by asking us to delete your account, from the dashboard or by email to [email protected]. Deletion follows the steps in the Privacy Policy — a 7-day grace period, then deletion within 30 days — and the agreement ends when it completes; what we keep afterwards is listed there. We may end it with 30 days' notice by email to your account address, or at once if you materially breach these terms and do not cure the breach within 14 days of being told. Clauses that by their nature should survive — fees owed, proof tokens, intellectual property, confidentiality, liability, governing law — survive termination.
14. Changes to these terms
We may change these terms. Changes to wording, links or contact details take effect when published. For any other change we will tell you by email or in the dashboard at least 30 days before it takes effect; if you do not agree, you may end the agreement before that date. The version and date at the top of this page identify the terms in force.
15. Governing law and venue
This agreement is governed by the laws of the Republic of Lithuania. Disputes are brought before the courts of Vilnius, Lithuania. If you are a consumer, the mandatory rules of the country where you live, and your right to bring a claim there, are not affected. Nothing here limits your rights under the General Data Protection Regulation.
