Privacy Policy

Our core promise

Your input and results never leave your browser. Every tool computes locally; we have no endpoint that receives them.

What we collect

  1. Anonymous usage analytics: how often a tool is opened, execution counts, success/failure, duration ranges, and input size buckets (e.g. 1-10KB). Session identifiers rotate daily. We do not store raw IP addresses — only a country/region derived from the IP.
  2. No-result search queries: used to discover tools users need that we don't have yet. Aggregated and anonymous, with no user identifier.
  3. Account data (signed-in users only): email, display name, plus the tool slugs you favorite and non-sensitive option preferences. We never store sensitive values such as keys or private keys.

What we never collect

  • Input content, results, or file contents
  • Full URLs (only the tool identifier)
  • Raw IP addresses

Cookies and local storage

We use localStorage for theme, language, favourites and recent tools (under the devutils: namespace). Sign-in sessions use an httpOnly cookie for the refresh token. You can turn off analytics in settings.

Retention

Tool usage details are kept for 90 days, daily aggregates are kept indefinitely, and ad statistics for 180 days.

Your rights

You can export all personal data or delete your account at any time from the account page (data is fully erased within 30 days).
