Privacy Policy

Stillwise has no accounts. We don't ask for your name, email or phone number. For the coach (AI) to say the right thing at the right moment it needs the information below, and we process only that.

1. What we process

• A random device identifier and secret created on your device the first time you open the app. The server stores only a hash of the secret. It is not linked to your real identity.
• Your settings: goals, coach style, block schedule, quiet hours, and your daily screen-time estimate.
• Names of the apps you chose and minutes of use: on Android, the name and package name of the chosen app and how many minutes you have used it in a row and today. On iPhone, Apple does not reveal app names, so we only receive that today's combined time in your chosen apps passed a number of minutes.
• Your conversation with the coach: the coach's notifications, the buttons you tap (I'll stop, Lock, etc.) and anything you write to the coach.
• Access logs (IP address, time of request), kept briefly for security and troubleshooting, then deleted automatically.
• Purchases: payments are handled by the App Store or Google Play; we never see card details. RevenueCat processes your receipt and the device identifier above to check your subscription.

We do not collect screen contents, messages, photos, contacts, location or browsing history.

2. Android accessibility service

On Android the app uses an accessibility service only to know which app is in the foreground (its package name), so it can block your chosen apps during your scheduled hours and let the coach check in when you have been scrolling for a while. It does not read text on the screen or what you type (canRetrieveWindowContent=false) and uses this for nothing else.

3. iPhone Screen Time

On iPhone the app uses Apple's Screen Time APIs (FamilyControls, DeviceActivity). The apps you choose are given to us only as encrypted tokens, so we cannot tell which apps they are, and your usage history never leaves the device.

4. Why

To apply your block schedule, write the coach's nudges, remember the plans you tell the coach, check your subscription and prevent abuse.

5. AI processing and service providers

• Google LLC (Gemini API, USA) receives the settings, app names, minutes and conversation described above to write the coach's nudges and replies. The app asks for your consent before this. We use the paid API; Google does not use this data to train its models, but may keep requests for a limited period (up to 55 days) to detect policy violations.
• RevenueCat, Inc. (USA): subscription status.
• Google Cloud (Seoul region, South Korea): hosting and storage.

6. Retention

Conversation history is kept for 90 days; plan notes are removed when their time passes. Everything for a device unused for 180 days is deleted. Disaster-recovery backups are kept for 7 days.

7. Your rights and deletion

Tap Settings → Delete all my data in the app to erase your data from our server immediately (backups expire within 7 days). Settings stored on your device disappear when you delete the app. Already deleted the app? See how to delete your data.

8. Children

The app is not directed to children under 14, and we do not knowingly collect their information.

9. Ads and tracking

No advertising SDKs and no cross-app tracking (ATT).
