Your data and how to delete it

Last updated November 6, 2026

Practitioner's Atlas, published by Base Nine Studios, has no accounts. Almost everything you make stays on your phone, and you can delete it yourself. This page explains what we hold and how to ask us to delete it.

Data on your phone

Your chart, the people you work with, their notes and sessions, and everything you save are kept only on your device. We never receive them, so we can't delete them for you. Uninstalling the App or clearing its storage removes all of it. To delete it:

• Delete any chart, person, item, or session in the App.
• Or clear everything: Android Settings → Apps → Practitioner's Atlas → Storage → Clear data, or uninstall the App.

To keep a copy first, use Settings → Your data → Export everything in the App (free for everyone).

Data we hold

• Your RevenueCat customer record. If you subscribed or started a trial, RevenueCat holds your purchase history (product, transaction identifiers, purchase and renewal dates, country) under an anonymous app user ID.
• Redemption records. If you redeemed a code, Cloud Firestore holds a record of it: the code, your anonymous app user ID, and the time.
• Your cloud backup. If you switched on backup, Cloud Firestore holds an encrypted copy of your saved work under your app user ID. It is encrypted with your passphrase, so we can't read it. You can delete it yourself in the App: Settings → Your data.

We hold no name, email address, payment details, location, or anything you entered in the App in readable form.

How to request deletion

Email apps@baseninestudios.com with the subject “Delete my Practitioner's Atlas data”. Because there are no accounts, include something that lets us find your records:

• your Google Play order number (it starts with “GPA.” and is in your Google Play purchase receipt), and/or
• the code you redeemed.

What gets deleted, and when

• We delete your RevenueCat customer record any redemption records, and any cloud backup tied to your app user ID.
• We confirm by email within 30 days of your request.
• Google keeps its own records of your Google Play purchases under Google's Privacy Policy. Records required for tax and accounting may be kept for as long as the law requires, isolated from any other use.
• Service providers' standard request logs (such as IP addresses) expire on their own schedules.
