Privacy Policy

Short version

Pink Bright lets you pick one photo a day from your own Photos library. Apple's on-device Vision framework extracts contour vectors using VNDetectContoursRequest and the app renders them into a line-art PNG. The app saves the source PNG, the rendered line-art PNG, the count of contours Vision found, an optional note, and the date. Everything stays 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 Bright 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 Bright never opens the camera or records audio; it only reads photos you explicitly pick.
• No location. Pink Bright does not request location permission and does not read EXIF GPS metadata from your photos.
• No contacts, no calendar.
• No HealthKit, no Health data.

Photos permission

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

On-device Vision (contour detection)

The contour vectors are extracted by Apple's on-device Vision framework using VNDetectContoursRequest (available since iOS 14). The request executes inside your iPhone, returns vector paths describing the edges Vision found, and the pixels of your photo never leave the device. Pink Bright then renders those vectors into a single line-art PNG locally.

Pink Bright does NOT use Apple's Foundation Models, Image Playground, or any other generative model. The line-art is a direct render of contours Vision returned for the photo you picked; nothing about the image is synthesized or hallucinated.

What stays on your device

• Your bright entries (the source PNG you picked, the rendered line-art PNG, the count of contours Vision returned, an optional note you typed, 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.

The original photo continues to live in your Photos library. Pink Bright keeps only its own copy of the still plus the rendered line-art so it can show the entry without re-running Vision. Pink Bright 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 Bright has stored.

Lock Screen widget

Pink Bright Pro includes a Lock Screen widget that shows today's bright count. The widget reads only the count and the timestamp of the most recent entry 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 Bright 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 Bright 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 Bright 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.
