Privacy Policy

Short version

Pink Cinder uses the iPhone's rear camera to capture a photo and a depth map simultaneously through AVCapturePhotoOutput and AVCaptureDepthDataOutput, then renders a false-color depth visualization on-device. The HEIC photo, the depth visualization PNG, the minimum and maximum depth in meters, 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 Cinder 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. Pink Cinder never records audio.
• No Photos library access. Pink Cinder does not read or write to your Photos library; cinders live only inside the app.
• No location, no contacts, no calendar.
• No HealthKit, no Health data.

Camera permission

Pink Cinder requests Camera access (the NSCameraUsageDescription permission) so it can capture a photo together with depth data through Apple's AVFoundation stack. The camera is opened only while you are inside the capture screen and is released as soon as you back out.

Depth capture requires an iPhone with a dual-camera system or a LiDAR scanner (iPhone 7 Plus, 8 Plus, X, and later Pro/Pro Max models). On devices without a supported depth-capable camera, the capture screen will display a notice and the depth map step is skipped.

Pink Cinder does NOT run any face detection, body pose, scene classification, or other computer-vision pipeline on what the camera sees. The only processing is the device's built-in depth estimation surfaced by AVFoundation plus the false-color mapping the app applies to render the visualization.

What stays on your device

• Your cinder entries (the HEIC photo bytes, the rendered false-color depth visualization PNG, the minimum and maximum depth values in meters, an optional note you typed, and the created-at timestamp). Stored in on-device SwiftData with the photo and visualization 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 the day-three gift screen has been acknowledged.

The photo and depth map are written only to Pink Cinder's private container. The app does not save the capture to your Photos library and does not upload it anywhere.

All of the above lives on your device and never leaves it. Uninstalling the app deletes everything Pink Cinder has stored.

On-device depth rendering

The depth map produced by the camera is processed in-memory by the app, mapped to a false-color visualization, and written to disk as a PNG. The rendering uses Core Graphics and runs entirely on your device. No depth data is uploaded anywhere and no machine-learning model is contacted off-device.

Lock Screen widget

Pink Cinder Pro includes a Lock Screen widget that shows today's cinder count. The widget reads only the count and the timestamp of the most recent capture from an App Group container on your device. No photo or depth 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 Cinder 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 Cinder 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 Cinder does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke Camera permission, use iOS Settings → Privacy & Security → Camera. 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.
