How to delete everything HatLab holds about you. There is very little, and most of it never leaves your device.

App and publisher

HatLab, published by Safiye Meram, Esenler/Istanbul, Türkiye. Contact: gelistirbizi@gmail.com.

1. Data on your device

Your sheets, your scores, your nib calibration and your settings are stored on the device only.

• To erase them inside the app: Settings, then Erase progress and sheets. This is immediate and cannot be undone.
• To erase them by removing the app: delete HatLab from the device. Everything it stored goes with it.

2. Purchase record

If you have bought Premium, a purchase record exists at RevenueCat, Inc., our purchase processor: a random anonymous identifier, the store receipt, the store country and the app version. It contains no name and no email address.

• To have it deleted, write to gelistirbizi@gmail.com with the subject "HatLab data deletion" and the store receipt or order number.
• It is deleted within 30 days of the request.
• Deleting it ends the entitlement: Premium stops working on every device, and restoring it afterwards will no longer be possible.

3. What we cannot delete

Apple and Google keep their own record of the transaction under their own policies and their legal obligations. Ask them directly through your store account. The publisher has no access to those records and cannot remove them.

4. Retention

Device data: until you erase it or delete the app. Purchase record: for as long as the entitlement needs to be verifiable, and deleted on request as described above.
