Privacy
Short version: this website collects your email only if you join the waitlist. The app collects nothing.
In the app · Your data stays hereOn this phone, encrypted. No account, no server, no analytics or ad SDK. We can't see your data, and no one else can either.
This website
- Waitlist email. If you join, we store your email, the page and language you joined from, the time, and your phone type if you choose to tell us. It is kept in our website host’s storage (Cloudflare), only so we can send one email at launch. We do not store your IP address; to stop abuse, a counter derived from your network and the date is kept for two days. Ask at [email protected] and we delete your address.
- Visit counts. We count page visits with Plausible, which uses no cookies and stores no personal data.
- No tracking. No advertising pixels, no social media trackers, no selling or sharing of data.
The Weekmark app
- No account, no server and no third-party analytics, advertising or crash-reporting SDKs.
- Your log lives in an encrypted database on your phone. Progress photos are encrypted too.
- Apple Health and Health Connect data is read and written on your phone, only for the types you allow.
- Purchases go through the App Store or Google Play; we receive no payment details.
- Backups and exports are files you create and keep. Backups are encrypted with your passphrase.
- Reminders are scheduled on your phone. You can hide medicine names from notification text.
The honest exceptions
- Apple/Google process your purchase.
- Exports you create are yours. They go only where you send them.
- Your log is not included in phone backups. To move to a new phone, use a Weekmark backup (Pro) or export your data as CSV.
- Backups are encrypted with your passphrase before they leave the app. Without it, nobody — including us — can open them.
- If you turn on Apple Health / Health Connect, the values you choose are shared with Apple Health / Health Connect, which handles them under its own settings.
- If you add the Weekmark home-screen widget, your next dose (medication name, amount, time, site and supply) is stored for the widget outside the encrypted log and, on iPhone, included in backups.
- On iPhone, if you add only the lock screen widget, the times of your next and last dose, whether maintenance mode is on, your Pro status and the app language (no medication name, amount or site) are stored for the widget outside the encrypted log and included in phone backups.
- Reminders you turn on show the medicine name unless you turn off "Show medication names in reminders" in Settings. Your phone keeps upcoming reminder text outside the encrypted log until it fires.
The app’s Settings › Privacy screen lists the few places where text is stored unencrypted on your phone (for example, scheduled reminder text and the home-screen widget).
