Privacy Policy

Short version

Pink Quiver lets you pick two photos from your Photos library (a “before” and an “after”) so Apple's on-device Vision framework can compute the motion vectors between them. The resulting optical-flow field is rendered as a colored overlay on top of the two source frames and saved as a dated entry. The two source PNGs and the flow field PNG 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 Quiver 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 Quiver reads only photos you explicitly pick.
• No location, no contacts, no calendar.
• No HealthKit, no Health data.
• No face detection, no person identification, no object recognition. Pink Quiver only computes pixel-level motion vectors between two frames.

Photos permission

Pink Quiver requests Photos access (the NSPhotoLibraryUsageDescription permission) so that the system picker can show you photos to choose from. The permission is used only on the two images you explicitly pick for a given quiver entry, through Apple's PhotosPicker.

Pink Quiver does NOT scan your broader library, does NOT build an index of your photos, does NOT extract face data, EXIF, or location metadata, and does NOT read any image other than the two you pick for a given quiver entry.

On-device optical-flow computation (Vision)

Pink Quiver uses Apple's Vision framework, specifically VNGenerateOpticalFlowRequest, to compute the motion vector field between the two picked images. The request runs entirely on your iPhone's Neural Engine. The two images are held in memory for the duration of the request and are then saved alongside the rendered flow field as part of the quiver entry. Vision is not asked to detect faces, classify objects, or identify any person; it produces only a dense field of pixel-displacement vectors.

What stays on your device

• Your quiver entries (the two source PNGs that you picked as the before/after frames, the rendered flow-field PNG drawn from the motion vectors, an optional label you type, and the created-at timestamp). Stored in on-device SwiftData with the image 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.

All of the above lives on your device and never leaves it. Uninstalling the app deletes everything Pink Quiver has stored, including the saved copies of the source photos.

In-app purchases

Pink Quiver is free for the first three quiver entries lifetime. After that, you may subscribe (Monthly $4/month with a 14-day intro, Annual $25/year) or unlock the Lifetime tier ($59 one-time) to compute unlimited flow fields. The 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 Quiver 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 Quiver 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 Quiver 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, including the saved copies of the source photos, 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.
