Summary
Constant Change is designed as a local-first app. It has no user accounts, no ads, no third-party tracking, and no server upload feature in the current version.
What data the app processes
Photos and sequences
The app stores the photos you capture, recorded-change titles and descriptions, template choices, alignment transforms, and video export settings locally on your device.
Photo metadata
Each photo can store date, notes, place text, measurement labels, and measurement values that you enter or choose to add.
Camera
If you grant camera access, Constant Change uses the camera to capture photos for your recorded changes. Camera access is only used while taking photos.
Health data
If you select Apple Health metadata for a recorded change, the app can read the Health values you approve, such as weight, and attach them to photos or video annotations. This is useful for body-focused recordings such as weight loss or muscle gain. Health access is optional, not needed for recordings such as plants, and the app does not write Health data.
Location
If you grant location access and choose the location button, the app can use your current location to fill the place field for a photo. You can also type any place text manually.
Exports and sharing
You can export MP4 videos or Constant Change archive files and share them through the iOS share sheet. Sharing only happens when you explicitly start an export/share action.
Protected changes and Face ID
You can protect sensitive recorded changes with a password. This is useful when photos document private physique progress, pregnancy, weight loss, muscle gain, or other body-focused changes that may show you partially unclothed. Face ID or Touch ID can be used as an optional on-device convenience for unlocking protected changes. Biometric authentication is handled by iOS; Constant Change receives only whether unlocking succeeded or failed.
What Constant Change does not do
No advertising
Constant Change does not show ads and does not use advertising SDKs.
No tracking
Constant Change does not use third-party tracking for marketing or cross-app profiling.
No account required
You do not need to create an account to use the app.
No app server
The current version has no server feature and no public upload or gallery feature.
No face data collection
Constant Change does not collect, store, process, transmit, retain, delete, sell, or share face data. Face ID and Touch ID are provided by Apple's LocalAuthentication framework. The app never receives face images, Face ID sensor data, depth data, face geometry, biometric templates, or biometric identifiers.
Your control
Permissions
You can change or revoke camera, Health, location, and Face ID permissions at any time in iOS Settings.
Deletion
You can delete photos and recorded changes inside the app. Removing the app from your device also removes locally stored app data, subject to normal iOS backup behavior.
Backups
App data is stored locally in the app container and may be included in normal device backups depending on your iOS and iCloud backup settings.
