Privacy Policy

Short version

Pink Brush turns one feeling word into a small painted MP4. You type a single word; Apple's on-device Image Playground generates a painterly still from it; the app then composes a six-second video with a slow Ken Burns zoom using AVAssetWriter. The MP4 and its thumbnail stay on the 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 Brush 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, no photos, no contacts.
• No location, no calendar, no Health data.
• No language model. Pink Brush does not use Apple's Foundation Models. It only uses Image Playground for painting generation.

Permissions used

None. Pink Brush requests no iOS permissions. It does not access the microphone, camera, Photos library, contacts, calendar, location, or Health. Saving the MP4 to the Photos app is something you can do manually through the standard iOS share sheet; the app itself never reaches into your library on its own.

What stays on your device

• Your painting entries (the feeling word you typed, the MP4 filename, a small thumbnail of the painted still, the duration in seconds, and the date created). Stored in on-device SwiftData as PaintingEntry records.
• The MP4 files themselves, written to the app's sandbox container by AVAssetWriter.
• 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 image generation (Apple Intelligence)

Pink Brush paints each still with Apple's on-device Image Playground, accessed through the public Image Playground API on iOS 26. The painterly image is produced on your iPhone's Neural Engine. The feeling word you typed is passed to Image Playground in-process and never leaves the device. Pink Brush does not use Apple's Private Cloud Compute fallback for this feature.

Painting generation is available only on Apple Intelligence-capable devices running iOS 26 or later (iPhone 15 Pro, iPhone 16, or newer). On older devices, the app surfaces a friendly fallback explaining that the painting step requires Apple Intelligence and is not available.

The Ken Burns zoom and the MP4 packaging step are done by AVAssetWriter, which is part of Apple's AVFoundation framework. This step is fully local and uses no network.

Free vs Pro

Pink Brush is free for the first three days after install with every feature unlocked. After that, the Free tier allows up to three paintings lifetime. Pro unlocks unlimited paintings, a year-in-review animated wall MP4 export, and the Lock Screen widget. Pricing is $4/month, $25/year, or $59 one-time Lifetime.

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 Brush 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 Brush 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 Brush 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, simply delete the app.

Changes

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