Privacy Policy

Short version

Pink Haiku does not collect, store, or transmit any personal data. You type a single seed word; Apple's on-device Foundation Models writes a three-line haiku from it; Apple's on-device Image Playground paints a distinct scene for each line; the app then composes the three scenes into a nine-second MP4 using AVAssetWriter with the haiku text drawn as an on-screen overlay. The seed word, the haiku text, the scene images, and the resulting MP4 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 Haiku 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 camera, no photo library access. The app generates scene images on-device; it does not import or capture any photo.
• No audio input or output. The app composes haiku videos as silent visuals with text overlay; it does not record, synthesize, or play any sound.
• No location, no contacts, no calendar. The app does not request any sensitive iOS permission.
• No HealthKit, no Health data.

System permissions

Pink Haiku requests no iOS system permissions. The app does not call any consent-gated API. You can confirm this in iOS Settings → Pink Haiku, where no permission toggles will appear.

What stays on your device

• Your haiku entries (the seed word you typed, the three lines of haiku text produced by the on-device language model, the filename of the nine-second MP4 stored inside the app sandbox, and a small thumbnail used by the year feed widget). Stored as HaikuVideoEntries records in on-device SwiftData. Larger payloads such as the thumbnail data use SwiftData externalStorage attributes so the store stays compact.
• The composed nine-second MP4 file for each haiku. Stored as a regular file inside the app's sandbox documents directory. The MP4 contains the three Image Playground scenes morphed together with the haiku lines drawn as a text overlay.
• 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 it.

On-device language model (Apple Intelligence)

The haiku-writing step uses Apple's on-device Foundation Models, accessed through the public LanguageModelSession API on iOS 26. This model executes on your iPhone's Neural Engine. Your seed word is passed to the model in-process and never leaves the device. The app does not use Apple's Private Cloud Compute fallback for this feature.

The three scene images come from Apple's on-device Image Playground, accessed through the public ImagePlaygroundConcept and ImageCreator APIs on iOS 26. Image generation also runs on-device. The three rendered images and your original seed word never leave your iPhone.

Pink Haiku is available only on Apple Intelligence-capable devices (iPhone 15 Pro, iPhone 16, or newer) running iOS 26 or later. On older or unsupported devices, the app cannot generate haikus.

Video composition

Once Foundation Models has written the three lines and Image Playground has painted three scenes, Pink Haiku composes the nine-second MP4 entirely on-device using AVAssetWriter. Each scene holds for three seconds with a brief morph between them, and the corresponding haiku line is drawn as a Core Graphics text overlay on top. No frames, audio, or metadata are uploaded anywhere; the MP4 is written directly to your app sandbox.

In-app purchases

Free use includes up to three haiku videos lifetime. Pink Haiku Pro unlocks unlimited haiku generation, the year feed of all your composed videos, and the Lock Screen widget. 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 Haiku 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 Haiku 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 Haiku does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke all access and remove all on-device state, including every composed MP4, simply delete the app.

Changes

If we ever introduce a feature that involves any data leaving the device (for example, cloud sync of composed videos), this page will be updated and the “Last updated” date at the top will change. For v1.0, no such feature exists.
