Terms of Service

Last updated: 29.05.2026

These Terms of Service ("Terms") govern your use of dmskey.com and related services provided by VALERY GROMOV ("DMS", "we", "us", "our").

By accessing or using the service, or by purchasing a paid plan or add-on, you agree to these Terms.

If you do not agree, do not use the service.

1. The service

DMS is a digital inheritance and recovery-preparation tool designed to help users prepare encrypted vault materials and split recovery authority across trusted people.

The service is designed so that core cryptographic operations take place in the user's browser. In the standard flow, DMS does not take custody of your plaintext vault contents, recovery shares, or decryption keys.

2. Eligibility

You may use the service only if you are legally capable of entering into a binding agreement under the laws that apply to you.

If you use the service for a business or organization, you represent that you have authority to bind that entity.

3. No legal, fiduciary, financial, or estate-planning advice

DMS is a software product, not a law firm, fiduciary, trustee, executor, financial adviser, or notary.

Any legal letter, template, recovery instructions, jurisdiction field, or consent language provided through the service is offered as a practical supporting tool only. It does not replace a will, trust, power of attorney, probate process, notarial act, or advice from qualified local counsel.

You are solely responsible for determining whether your plan, document set, and designated people are appropriate for your situation and local law.

4. Your responsibilities

You are responsible for:

  • the accuracy of the information you enter;
  • the security of your devices, browser, downloads, printouts, and local storage;
  • choosing trustworthy custodians, heirs, and executors;
  • verifying that your recovery plan works for your situation;
  • complying with laws that apply to your digital assets, accounts, and estate plan;
  • keeping copies of materials you may need in the future.

You must not rely on DMS as your only recordkeeping system.

5. Acceptable use

You may not:

  • use the service for unlawful, fraudulent, deceptive, or abusive purposes;
  • attempt to interfere with the service or bypass security controls;
  • use automated means to scrape, overload, or disrupt the service;
  • misrepresent your identity or payment information;
  • use the service in a way that infringes others' rights;
  • upload or submit malicious code.

6. Purchases, pricing, and payment

Paid plans and add-ons are offered at the prices shown at checkout. Payments are processed by third-party payment providers such as Stripe.

We may change pricing for future purchases, but price changes will not retroactively affect completed purchases unless required by law or clearly stated at the time of sale.

You authorize us and our payment providers to process the payment method you provide for the amount shown at checkout, including applicable taxes where relevant.

7. Digital products, activation, and delivery

DMS provides digital features such as expanded K-of-N options, watermark removal, legal-letter generation, and related entitlements.

Delivery may occur by activation of features, entitlement issuance, token delivery, or other digital fulfillment methods.

You are responsible for supplying accurate purchase and recovery information, including the email address used at checkout where applicable.

8. Refunds and cancellation

Unless otherwise stated at checkout or required by mandatory law, purchases of digital products are final once the digital feature has been delivered, activated, accessed, or made available.

Where the service or a paid digital feature is made available immediately after purchase, you request immediate performance of the contract. Where applicable law requires it, you also acknowledge at checkout that immediate performance of digital content or digital services may affect or end your right of withdrawal once delivery has begun.

If you believe you were charged in error, purchased the wrong plan, or could not access the paid feature because of a technical problem, contact support@dmskey.com and include the email address used at checkout together with any relevant order or license reference.

Unless mandatory law provides otherwise, refunds are generally not available after the paid digital feature has been delivered, activated, accessed, or made available. We may, at our discretion, offer a refund or credit in individual cases, including duplicate purchases, accidental payments, or verified technical failures.

Approved refunds are issued through Stripe or the original payment method. After we submit a refund, the time it takes to appear on your statement depends on your bank or payment provider.

Nothing in these Terms limits any non-waivable consumer rights you may have under applicable law.

9. License to use the service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the service for its intended purpose.

We retain all rights, title, and interest in the service, including all software, branding, text, design, and documentation, except for rights we expressly grant to you.

10. Your content

As between you and DMS, you retain rights in the information you create or prepare using the service.

If you choose to contact support and share information with us in doing so, you grant us the limited rights needed to receive, store, and process that information for the purpose of responding to your request.

You represent that you have the right to use any information you submit.

11. Availability and changes

We may change, suspend, or discontinue any part of the service at any time.

We do not promise uninterrupted availability, permanent feature support, or error-free operation. Recovery success may depend on factors outside our control, including the completeness of your materials, the integrity of third-party files or printouts, device condition, and whether the required number of custodians can participate.

12. Important disclaimers

The service is provided on an "as is" and "as available" basis to the maximum extent permitted by law.

To the maximum extent permitted by law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, quiet enjoyment, and any warranty that the service will meet your needs or produce a legally effective estate-planning result.

Without limiting the above:

  • we do not guarantee that any legal letter or instruction packet will be valid or sufficient in your jurisdiction;
  • we do not guarantee that any specific custodian, heir, executor, court, bank, exchange, or service provider will accept or act on your materials;
  • we do not guarantee recovery if materials are incomplete, inaccurate, damaged, lost, or mishandled;
  • we do not guarantee uninterrupted service availability.

13. Limitation of liability

To the maximum extent permitted by law, DMS and its officers, directors, employees, contractors, and affiliates will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, goodwill, use, data, business opportunities, digital assets, or expected inheritance, even if we were advised that such damages were possible.

To the maximum extent permitted by law, our total liability arising out of or relating to the service or these Terms will not exceed the greater of:

  • the amount you paid us for the specific paid feature giving rise to the claim during the 12 months before the event giving rise to the claim; or
  • €50.

Some jurisdictions do not allow certain exclusions or limitations, so some parts of this section may not apply to you.

14. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless DMS and its affiliates, personnel, and service providers from claims, losses, liabilities, and expenses arising from:

  • your misuse of the service;
  • your violation of these Terms;
  • your violation of applicable law;
  • your infringement of another person's rights.

15. Privacy

Our Privacy Policy governs how we collect, use, and disclose personal data.

16. Third-party services

The service may depend on or link to third-party services, including payment processors, hosting providers, analytics providers, or storage providers. We are not responsible for third-party services except as required by law.

17. Suspension and termination

We may suspend or terminate access to the service if we reasonably believe you violated these Terms, created security risk, engaged in fraud or abuse, or if suspension is needed to protect the service, users, or third parties.

You may stop using the service at any time.

Sections that by their nature should survive termination will survive, including sections on disclaimers, liability, indemnity, governing law, and dispute resolution.

18. Governing law and disputes

These Terms are governed by the laws of Poland, excluding its conflict-of-laws rules.

Any dispute arising out of or relating to these Terms or the service will be resolved exclusively in the courts of Poznan, Poland, unless mandatory consumer law provides otherwise.

19. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will update the "Last updated" date and provide notice where required.

Your continued use of the service after the updated Terms become effective means you accept them, except where applicable law requires additional consent.
