1. The Service

Blockchain Explorer is a public, read-only verification service for inspecting cryptographic record integrity anchors published by the myAviationTools platform. It allows anyone to verify that a given aviation record hash matches an on-chain anchor without revealing the underlying record content. The Service does not store personal data for public (unauthenticated) lookups.

2. Eligibility

Public verification lookups are available to anyone without an account. Authenticated features (batch history, saved searches) require an account and that you be at least 18 years old with legal capacity to enter into binding contracts.

3. Account

You are responsible for safeguarding your account credentials and for all activity under your account. Notify us immediately if you suspect unauthorized use. Sessions expire after 30 days and are refreshed daily while you are active; you may end a session at any time by signing out.

4. Fees

Public verification on Blockchain Explorer is free. Blockchain Explorer has no separate paid plan and does not charge fees of its own. Paid plans are the myAviationTools Pro and Fleet plans described at myaviationtools.com/pricing; they are billed and governed under the terms of those plans, not these.

5. Nature of the Verification Service

The Blockchain Explorer confirms only whether a submitted hash matches a previously anchored value on the Sepolia Ethereum test network. A positive verification result confirms hash integrity, not the factual accuracy of the underlying record. We make no representations as to the accuracy, completeness, or legal sufficiency of any record whose hash appears on-chain. Use of verification results as legal or regulatory evidence is the responsibility of the relying party.

6. Acceptable Use

• Do not submit automated bulk verification requests beyond documented API rate limits.
• Do not reverse-engineer or scrape the Service.
• Do not attempt to de-anonymize records from on-chain hashes.
• Do not use the Service to make false claims about record integrity.

7. Your Data

Public verification lookups are stateless — we do not log the hashes you submit for anonymous queries. Authenticated users' query history may be stored for their own reference. See our Privacy Policy for details.

8. Termination

You may delete your account at any time from Settings → Delete account. When you delete your account, your name and email are replaced with dummy values and you are signed out everywhere. We still keep your original name and email, and your files, so the account can be restored. We do not automatically erase them on a schedule. To have them erased, email [email protected]. Some records are kept where the law requires. Hashes already written on-chain cannot be removed. We may suspend or terminate accounts for violation of these Terms with notice where practicable.

9. Disclaimers

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. We do not warrant uninterrupted service, error-free operation, or the continued availability of any specific on-chain anchor. Blockchain networks are outside our control; testnet anchors may be subject to network deprecation.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (a) $100 USD or (b) the fees you paid us in the 12 months preceding the claim.

11. Governing Law

These Terms are governed by the laws of the State of Texas, without regard to its conflict-of-laws provisions. Any dispute will be resolved exclusively in the state or federal courts located in Texas.

12. Changes

We may update these Terms; if we make material changes we will notify you by email or in-app at least 30 days before they take effect.

13. Contact

Questions about these Terms: [email protected]. We reply by email, usually within a few days.
