Privacy Policy

Anonymous verification

AVAT.app does not store any data about who submitted a query. In the verification logs (verification_logs and account_verification_logs) we never store:

• the requester's IP address
• the browser's User-Agent
• a session ID
• any other identifier of the requester

What we do store

We only store anonymous aggregated statistics — the number of checks per day, cache hit ratio, the number of rate-limited requests — with no link to any individual query or person.

Rate limiting

To prevent abuse, we use a short-lived fingerprint sha256(IP address + secret salt) as a Redis key with an automatic expiry (TTL). This fingerprint:

• exists only in Redis, nowhere else,
• is never stored in verification_logs,
• cannot be used to trace back to a specific query.

Cookies

The site uses only technical cookies required to run the admin area (editor login). No tracking or marketing cookies.

Accounts

The public verification tools require no registration or account. Accounts exist only for internal content administration.
