This privacy policy covers all apps published by Thorbjørn Bonvik, including Stronq, Prāṇa, ChromoTune, Overdubber, Simple Habits, and Strophe. Your privacy matters. This policy explains what these apps access and how it is handled.
App data — such as workout history, breathing session records, habit tracking, and settings — is stored locally on your device using Apple's SwiftData framework. This data is never transmitted to any server we operate.
Some apps offer optional iCloud sync as a premium feature. When enabled, your data syncs through Apple's iCloud service under your own Apple Account. We do not have access to your iCloud data.
Some apps can read and/or write data to Apple Health with your permission — for example, logging bodyweight entries or completed workouts. Health data stays on your device and in iCloud (if you have Health syncing enabled). We never send Health data to any external service.
Some apps use your device's microphone for real-time, on-device audio analysis — for example, pitch detection for tuning or capturing a recording you initiate. Audio is processed on your device; it is never uploaded, saved without your action, or transmitted anywhere by us.
In-app purchases are handled entirely by Apple through the App Store. We do not process or store any payment information.
Free versions of these apps may display ads served by Google AdMob. All ads are non-personalized — these apps never use App Tracking Transparency and do not ask for permission to track you. AdMob may still collect device identifiers and usage data to serve and measure non-personalized ads. You can learn more in Google's Privacy Policy. Premium/paid upgrades, where available, remove ads.
Beyond what the ad provider collects to serve non-personalized ads, these apps include no additional analytics SDKs or tracking frameworks. No personal data is collected, shared, or sold to third parties by the developer.
If an app offers reminders, notifications are scheduled locally on your device. No push notification service or external server is involved.
These apps are not directed at children under the age of 13. We do not knowingly collect personal information from children.
Since app data is stored locally on your device (or in your personal iCloud account), you have full control over it. Deleting an app removes all associated local data.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date. Since this single policy covers all apps, an update here applies to every app that links to it.
