What this website and the Plimova app store in your browser, and why.
Draft for legal review. Written to match what Plimova does today, but not yet checked by a solicitor. Highlighted items still need filling in.
On this page
01This website
This website doesn't set any cookies and doesn't use analytics, advertising or tracking. That's why there's no cookie banner. Its typefaces are hosted on our own server, so your browser doesn't contact any third party.
02The Plimova web app
When you sign in to the Plimova web app, we use only the cookies the app needs to work:
| Name | What it's for | How long |
|---|---|---|
| better-auth.session_token | Keeps you signed in | Up to 30 days, or until you sign out |
| better-auth.session_data | A signed copy of your session, so pages load quickly | Up to 1 day |
On the live site these names start with __Secure-, which means browsers only send them over secure connections. Because these cookies are strictly necessary, the law doesn't require us to ask for consent.
03Storage on your device
The web app also keeps a few things in your browser's local storage, which never leave your device:
- Your colour theme (light, dark or system).
- An unsent workout and workouts waiting to sync, so nothing is lost if you lose signal or close the page. They're removed once sent.
The iPhone and Apple Watch apps keep your sign-in in the device's secure keychain, and a copy of recent screens so they work offline. Signing out clears them.
04Crash reporting (Sentry)
When something breaks, we want to know so we can fix it. Plimova uses Sentry, a crash-reporting service, in its EU data region (Frankfurt, Germany). A report holds the error, where in our code it happened, the app version and the kind of device, operating system or browser. We remove anything about you before it's sent: never your name, email address, health or training data, what you typed, or the contents of any request. Sentry doesn't store IP addresses for us, and screen recordings (Sentry's "Session Replay") are off.
| Where | What it keeps on your device | Why |
|---|---|---|
| The web app | Nothing. No cookies or local storage; reports are sent straight to our own server, which passes them on to Sentry. | To find and fix errors in the web app |
| The iPhone app | If the app crashes, the report is saved in the app's own storage and sent the next time you open it, then deleted. Sentry also keeps a few small housekeeping files there, such as whether the last run ended in a crash. They aren't cookies, aren't used to track you, and no other app can read them. | A crash stops the app, so the report can only be sent on the next open |
| The Apple Watch app | Nothing. The watch app doesn't send crash reports. |
Crash reporting doesn't use cookies and isn't used for analytics or advertising.
