ThinkLeft ("the app") is designed with your privacy in mind. This policy explains what data we collect, how it is used, and your rights.
All data you enter into the app — decisions, mood check-ins, behavioral signals, and daily logs — is stored locally on your device using Apple's SwiftData framework. We do not operate servers or databases that store your personal information.
The app may request access to motion and fitness data (via CoreMotion) to enrich your fatigue score. This data is processed on-device and is never shared or transmitted off your device.
If you add the home screen widget, it reads data from the same local on-device store via an App Group shared container. No network requests are made.
Your app data may be included in iCloud backups if you have iCloud Backup enabled on your device. This is governed by Apple's iCloud Terms of Service, not ours.
The app is not directed at children under 13. We do not knowingly collect data from children.
If this policy changes, we will update the date at the top of this page. Continued use of the app constitutes acceptance of any updated policy.
