Common questions
Do I need an account?
No. Drinkyin works fully offline without an account, and your logs stay on your device. An account is optional and only needed to sync your logs across devices.
I did not receive my sign-in code
- Check your spam or junk folder.
- Codes expire. Wait a minute, then request a new one.
- Make sure the email address is typed correctly.
My logs are not syncing
- Check that you are signed in: tap your avatar (top right) → Account.
- Make sure you are online, then close and reopen Drinkyin — it syncs when the app opens or comes back to the foreground.
Reminders do not appear
- Allow notifications for Drinkyin in your device's system settings.
- On iPhone, check that a Focus mode is not silencing them.
- On Android, turn off battery optimization for Drinkyin if reminders arrive late.
A drink's nutrition information is wrong
Email us the drink name (and barcode, if it has one). Scanned products come from Open Food Facts, which anyone can also correct directly. Nutrition values in Drinkyin are informational and not medical advice — see our Terms of Use.
How do I delete my data or my account?
See Delete your Drinkyin account. In short: Settings → Account → Delete account removes your account and everything synced to it, and Settings → Data → Clear data / Reset clears the data on one device.
