Short version: your birth date and focus never leave your device.
Your birth date, lifespan, focus line and deadline are calculated and stored in your browser's local storage. They are never sent to us or anyone else. We use no cookies and no third-party analytics. We count anonymous page events (for example "wallpaper downloaded") with no personal data attached.
If you sign up for the Monday note, we store your email address only, to send that note. Every email has a one-click unsubscribe, which deletes your address.
Payments are processed by Stripe. We receive your email address and purchase record so we can deliver your license. We never see or store your card details.
The Mac app, browser extension and iPhone Shortcut store your settings on your own devices. They make no network requests other than checking your license.
