Privacy Policy
Last updated: 2026-08-16
The short version
Your projections are computed in your browser and are never stored by us. We store your account email and the plan facts you save — nothing else — and we never sell data or run advertising trackers.
What we store
Account: your email address (and a Google account identifier if you sign in that way). Plans: the calculator inputs you save — the wizard's facts and balances, plus check-in history. Growth events: anonymous rows recording that a card was downloaded or the planner was opened, with an optional referral code and locale; they never contain plan values.
What never leaves your browser
All simulation and solving runs locally in a background worker. Results — success probabilities, projections, solved answers — are computed on open and are not persisted anywhere.
Providers we rely on
Hosting and database (Neon Postgres, where plan inputs live), email delivery for sign-in links (Resend), sign-in with Google, scrubbed error monitoring (Sentry, configured with personal data stripped), and Google Analytics for page-level traffic (paths and referrers — plan values are never sent; they do not appear in URLs or events). If you are signed in, Google Analytics also receives your opaque account identifier to unify your visits across devices — it is not an email, name, or any other personal data. No advertising.
Cookies
A session cookie when you sign in, plus your theme and language preferences. Google Analytics, when enabled, sets its own measurement cookies (_ga and related) — they record page paths and referrers, never anything you type into the planner.
Retention and deletion
Plan data is kept while your account exists. Deleting your account in Settings hard-deletes your plans, check-ins, and account rows immediately and permanently — there is no soft-delete and no grace period.
Changes and contact
Material changes to this policy are posted here with a new date. Questions about your data can be sent from the email address on your account.
