Privacy Policy

Short version

Pink Drift does not collect, store, or transmit any personal data. Your steps, walking asymmetry, and reflections all stay on your device. The app has no accounts, no analytics, no third-party SDKs that contact a server, and does NOT read from or write to Apple Health. The only network calls the app makes are to Apple's StoreKit when you choose to subscribe or unlock the Lifetime tier.

Who we are

Pink Drift is published by Danielius Studio LLC, a Wyoming limited liability company at 30 N Gould St, Suite #5280, Sheridan, WY 82801, USA (“we”, “us”).

Motion permission (CoreMotion)

Pink Drift uses Apple's CoreMotion framework to read your step count and, where the iPhone provides it, your walking-asymmetry percentage. iOS will prompt you to allow Motion & Fitness access the first time you open the daily log. You can revoke this at any time in iOS Settings → Pink Drift → Motion & Fitness. Without the permission, the app still works for reflections; the step and asymmetry fields stay blank.

No HealthKit, no Apple Watch required

Pink Drift does NOT request HealthKit access. It reads only from CoreMotion (which is the same source Apple Fitness uses for step counting). Walking asymmetry is computed by iOS using your iPhone's motion sensors; an Apple Watch is not required.

Data we do NOT collect

• No account, no email, no password — the app has no signup.
• No analytics, no telemetry, no event tracking.
• No advertising identifiers (no IDFA, no fingerprinting).
• No usage data sent off the device.
• No HealthKit data.
• No camera, no microphone, no photos.
• No location, no contacts, no calendar.

What stays on your device

• Your daily drift entries (steps, distance, asymmetry%, your reflection text, the date). Stored in on-device SwiftData.
• The date the app was first launched (used to time the three-day no-strings free window). Stored in UserDefaults.
• Whether the day-three gift screen has been acknowledged.

All of the above lives on your device and never leaves it. Uninstalling the app deletes it.

In-app purchases

If you choose to subscribe (Monthly, Annual) or buy the Lifetime unlock, that transaction is handled by Apple's StoreKit. Apple processes the payment and shares only the receipt with the app so we can verify your entitlement. We never see your card number, billing address, or any personal information beyond Apple's opaque transaction identifier.

Subscription receipts are stored on-device by iOS and used to validate your entitlement when you re-open the app. They are not sent to any server we operate.

Family Sharing

Pink Drift Pro purchases (Monthly, Annual, Lifetime) are Family-Shareable through Apple's standard Family Sharing mechanism. Apple handles eligibility checks; we do not see who is in your family group.

Children

Pink Drift is rated 4+ in the App Store. Because the app collects no data at all, it complies with COPPA and similar children's-privacy regulations by design.

Your rights

Because Pink Drift does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke all access and remove all on-device state, simply delete the app.

Changes

If we ever introduce a feature that involves any data leaving the device (for example, cloud sync), this page will be updated and the “Last updated” date at the top will change. For v1.0, no such feature exists.
