Poolbook — Delete your data
Poolbook is published on Google Play by The Alchemist Code. The app has no accounts: we never ask for your name, email or password.
Data stored on your phone
- Open Poolbook.
- Go to Settings › Delete all my data.
- Tap Delete to confirm.
Your pools and spas, water tests, chemical products, the doses you added, maintenance tasks and chemical spending are erased immediately and for good, and pending task reminders are cancelled. Uninstalling the app also removes them.
Files you exported yourself (CSV or backup) are not touched: they are yours, wherever you saved or sent them. If your phone backs up to your Google account, Android may still hold an older device backup; you can delete it in your Google account under Google Drive › Backups.
Deleting your data does not cancel a subscription or undo a purchase: your Premium stays linked to your Google Play account. Cancel a subscription in the Google Play Store under Payments & subscriptions › Subscriptions.
Data held by the services the app uses
Crashlytics, Analytics and AdMob tie their records to anonymous identifiers, not to your name. Google Play keeps your subscription and purchases under your Google account.
| Service | What is kept | For how long |
|---|---|---|
| Firebase Crashlytics | Crash reports | 90 days, then deleted automatically |
| Google Analytics for Firebase | Usage events linked to an app-instance ID | Deleted automatically after the retention period set in Google Analytics |
| Google AdMob | Ad interactions and the Android advertising ID | Under Google's retention policy. Reset or delete the advertising ID in Android settings › Privacy › Ads |
| Google Play | Your subscription, your purchases, purchase history and payment details | Kept by Google under its privacy policy. We never receive your payment details |
We don't run servers of our own and keep no copy of your data, your subscription or your purchases. For anything else, write to contact@thealchemistcode.org.
