Frequently Asked Questions

Where is my data stored?

All tanks, water test readings, water changes, reminders, and photos are stored locally on your device. TankLog does not require an account and does not sync your data to any server.

How do I back up my data?

Open Settings and use the backup feature to export a JSON file of your full tank history, which you can save or share using your device's share sheet. Use the same screen to restore from a backup file.

What does TankLog Pro unlock?

TankLog Pro is a one-time purchase ($4.99) that unlocks unlimited tanks, every water parameter chart with 2-parameter overlay, CSV export, and multiple reminder schedules. The free version lets you track 1 tank with unlimited logging, the pH chart, and 1 reminder.

How do I restore my purchase on a new device?

Open Settings and tap Restore Purchases. This re-verifies your TankLog Pro purchase with the App Store or Google Play and unlocks it again — no account needed.

How do I request a refund?

Purchases are processed by the Apple App Store or Google Play, so refunds must be requested through them directly, not through us.

I found a bug or have a feature request.

Email [email protected] with details (device, OS version, and what happened) and we'll take a look.
