Privacy Policy
Short version
Pink Rune lets you pick one photo from your own Photos library and runs Apple's on-device Vision framework (VNDetectRectanglesRequest) over it to find quadrilaterals such as doors, windows, signs, and paintings. The thumbnail with the rectangle overlay, the four corner coordinates of each detected rectangle, the rectangle count, and any note you type all stay on your device. There are no accounts, no analytics, and no third-party SDKs that contact a server. 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 Rune is published by Danielius Studio LLC, a Wyoming limited liability company at 30 N Gould St, Suite #5280, Sheridan, WY 82801, USA (“we”, “us”).
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 microphone, no camera. Pink Rune never opens the camera or records audio; it only reads photos you explicitly pick.
- No location, no contacts, no calendar.
- No HealthKit, no Health data.
Photos permission
Pink Rune does not ask for access to your Photos library. It uses Apple's system photo picker, which shows your photos without giving the app access to them, and the app reads only the photo you pick.
Pink Rune does NOT scan your broader library, does NOT build an index of your photos, does NOT extract face data, does NOT read EXIF or location metadata, and does NOT analyze any photo you have not handed to it through the picker.
What stays on your device
- Your rune entries (a downscaled thumbnail of the picked photo with the detected rectangles drawn on top, the four corner coordinates of each rectangle as JSON, the rectangle count, an optional note you typed, and the created-at timestamp). Stored in on-device SwiftData with the thumbnail bytes held as external storage.
- The date the app was first launched (used to time the three-day no-strings free window). Stored in
UserDefaults. - Whether you have Pro, so a paying customer opens the app unlocked.
The original photo continues to live in your Photos library untouched. Pink Rune keeps only the rendered thumbnail and the corner coordinates so it can show you the detection result when you open an entry. Pink Rune never modifies, deletes, or writes back to the original.
All of the above lives on your device and never leaves it. Uninstalling the app deletes everything Pink Rune has stored.
On-device Vision framework
Rectangle detection runs through Apple's Vision framework (VNDetectRectanglesRequest) and executes entirely on your iPhone. The pixel data is passed to Vision in-process and never leaves the device. Pink Rune does not contact any machine-learning service, does not send the photo to a server, and does not use any cloud fallback.
Pink Rune does NOT use any face-recognition, person-detection, text-recognition, scene-classification, or image-generation API. Only the rectangle-detection request is run.
Lock Screen widget
Pink Rune includes a Home Screen and Lock Screen widget that shows how many rectangles your runes found today. The widget reads only that count and the date it was saved from an App Group container on your device. No image data is rendered on the Lock Screen and nothing is sent off the device for the widget to function.
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 Rune 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 Rune 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 Rune does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke Photos permission, use iOS Settings → Privacy & Security → Photos. To remove all on-device state, delete the app.

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