Privacy Policy

Last Updated: August 10, 2026

Your plan is stored in your browser’s localStorage and stays on your device. There are no accounts, and we hold no copy of it. Clearing your browser’s data for this site deletes the plan.

Crash reports go to Sentry on the production site so breakage gets fixed. Your figures are stripped out of the error text before a report is sent, and the usage-count switch below turns crash reports off too.

Anonymous Analytics

We use privacy-respecting analytics (Umami, first-party and cookieless) to count page views and feature usage — no identifiers, no cookies, no plan data, and nothing you typed.

A page view records the page’s path without its query string, the site that linked you here, your browser language, a coarse screen size, and an approximate country that Umami derives from your IP address at the moment of the request and we never store.

Counts are on by default and you can opt out at any time: open Settings → General and switch off “Share anonymous usage counts.” It takes effect immediately on your device.

Email

Backups you request are delivered as email attachments via Resend, our email provider. Your plan goes to the address you type; we do not store it, and Resend keeps its record of the message it sent, like any mail service.

If you tick the updates box on that form, the address joins our updates list at Resend straight away. The backup email says so and carries a one-click unsubscribe link, as does anything we send you afterwards.

Who else is involved

  • Vercel — hosting; serves the site’s files to your browser.
  • Umami — the page views and feature counts described above.
  • Web3Forms — delivers the feedback form, if you use it.
  • Resend — email, as described above.
  • Sentry — crash reports, with your figures stripped out.

Questions, or to have an address deleted: use the Feedback link in the page footer. If any of this changes, the date at the top changes with it.
