Privacy Policy

Last updated: July 2026. We will note any changes at the top of this page.

Calculator inputs stay in your browser

  • All calculations run instantly in your browser — no data leaves your device.
  • No account is required to use any tool on this site.
  • Values you enter are never sent to our servers.
  • Do not enter confidential personal, medical, or financial information into any calculator.

Technical data

  • Hosting and CDN providers may log standard request data: IP address, browser type, requested pages, and timestamps.
  • We use Sentry for error monitoring, performance tracing, and diagnosing technical problems.
  • Sentry may receive technical details such as page URLs, browser and device information, error details, and interaction data when enabled.
  • Logs are retained according to the hosting provider's standard retention policy.
  • Technical data is used for delivery, reliability monitoring, security, and abuse prevention, not advertising.

Cookies and tracking

  • The core site does not use advertising or personalization cookies.
  • Sentry Session Replay may record page interactions to help reproduce errors. Text and input values are masked, and images and other media are blocked before replay data is sent.
  • Error replays are retained when a technical error occurs; a sample of other sessions may also be retained for reliability analysis.
  • Browser localStorage is used only to save your display preferences (decimal precision, favorites).

Data storage

  • All calculations run locally in your browser.
  • Calculator input text is masked from Session Replay before data is sent to Sentry.
  • If you submit the feedback form, the message you provide is sent to Sentry so we can respond to and diagnose the report.
  • No user accounts or server-side profiles are maintained.

Data retention

  • Favorite conversions and history are stored in your browser's localStorage.
  • This data never leaves your device and is deleted when you clear browser storage.
  • We do not maintain user accounts or server-side profiles.
