Privacy Policy

Short version

Pink Hue lets you pick a photo from your own Photos library and uses Apple's Core Image framework (CIKMeans k-means clustering) on-device to extract a five-color dominant palette. The five hex swatches, a 512-pixel thumbnail, and the note you typed 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 Hue 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 Hue 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 Hue requests Photos access (the NSPhotoLibraryUsageDescription permission) so that the system picker can show you photos to choose from. The permission is used only to read the photos you explicitly pick through Apple's PhotosPicker.

Pink Hue does NOT scan your broader library, does NOT build an index of your photos, does NOT extract face data, and does NOT read EXIF or location metadata beyond what is intrinsic to the frame you share with the app.

What stays on your device

• Your hue entries (a 512-pixel thumbnail of the picked photo, five dominant colors expressed as hex values in JSON, and the note you typed, plus 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-hue free window). Stored in UserDefaults.
• Whether the paywall has been acknowledged.

The original photo continues to live in your Photos library. Pink Hue keeps only the 512-pixel thumbnail plus the five hex values. Pink Hue 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 Hue has stored.

On-device palette extraction (Core Image)

Color clustering is performed by Apple's Core Image framework through the public CIKMeans filter. The filter clusters the photo's pixels into five dominant colors using the standard k-means algorithm. The computation runs entirely on your iPhone's GPU through Metal. No image data and no color result is transmitted off the device.

The output is a list of five RGB values that Pink Hue converts to hex strings (for example, #3F5B8C). No machine learning model, no face detection, and no biometric analysis is involved.

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 Hue 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 Hue 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 Hue 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.
