Privacy Policy

Short version

Pink Frost lets you pick one face photo from your Photos library so your iPhone can find the facial landmark points (eyes, brows, nose, lips, face contour). Pink Frost renders those points as a constellation diagram and saves the diagram with the underlying landmark coordinates. The face photo itself is discarded as soon as detection finishes — only the geometric landmark vectors persist. Pink Frost is not facial recognition, not identity verification, and does not match faces against any database. 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 Frost is published by Danielius Studio LLC, a Wyoming limited liability company at 30 N Gould St, Suite #5280, Sheridan, WY 82801, USA (“we”, “us”).

What Pink Frost is NOT

• Not facial recognition. Pink Frost does not compute a face print, face embedding, or identity vector. The landmark coordinates are not used to identify or re-identify any person.
• Not identity verification. Pink Frost cannot be used to confirm who anyone is, log anyone in, or authenticate against any system.
• Not a face database. Pink Frost does not search for, compare, or match the detected face against any other face, on or off your device.
• Not age, gender, mood, or attribute classification. Pink Frost only saves the geometric landmark positions and the constellation drawing.

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 Frost reads only the photo you explicitly pick.
• No location, no contacts, no calendar.
• No HealthKit, no Health data.

Photos permission

Pink Frost 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 single image you explicitly pick through Apple's PhotosPicker.

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

On-device face-landmark detection (Vision)

Pink Frost uses Apple's Vision framework, specifically VNDetectFaceLandmarksRequest, to estimate the facial landmark points (eyes, brows, nose, lips, and face contour) of a single face in the picked photo. The request runs entirely on your iPhone's Neural Engine. The image is held in memory only for the duration of the request and is then released; the source face photo is not written to disk by Pink Frost and is not kept after the constellation has been rendered.

What Pink Frost saves for each frost entry is the array of landmark coordinates that were found, the constellation PNG drawn from those coordinates, the number of faces found in the photo, an optional one-line note you type, and the created-at timestamp. The source face photo itself is discarded.

The landmark coordinates persist on-device only, as part of the entry; they are never compared against any other landmark set, on or off your device.

What stays on your device

• Your frost entries (the landmark coordinates, the constellation PNG drawn from those coordinates, the number of faces found, the optional note, and the created-at timestamp). Stored in on-device SwiftData with the constellation 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.
• A copy of your latest constellation, your latest note, your frost count and streak, and which of the last seven days have a frost, kept in a shared container on your device so the Pink Frost widget can show them.
• If you allow reminders, the time of day you usually open the app, so a few tips and reminders arrive at a good moment in your first week. They are scheduled on your device and nothing is sent to us.

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

In-app purchases

Everything in Pink Frost is unlocked for the first three days. After that, you can keep up to three frost entries for free. You may subscribe (Monthly $4/month, Annual $25/year) or unlock the Lifetime tier ($59 one-time) to draw unlimited constellations. 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 Frost 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 Frost 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 Frost 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.
