Privacy Policy
Short version
Pink Lull is an evening-before bedtime app. You grant read-only access to a few Apple Health categories you choose (for example steps, active energy, heart rate variability, sleep). The app reads today's values, Apple's on-device Foundation Models write a soft four-to-six-paragraph sleep story over the numbers, and Apple's built-in AVSpeechSynthesizer renders the story to audio at a slow, calm rate. The story text and the audio file both stay on your iPhone. 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 buy the Lifetime tier.
Not a medical device. Not medical advice.
Pink Lull is a personal sleep journal. It does not diagnose, treat, cure, or prevent any condition, including insomnia or any other sleep disorder. The bedtime stories are creative reflections written over your Health metrics, not clinical interpretations. Pink Lull is not a substitute for professional medical advice, diagnosis, or treatment. If you have sleep concerns, consult a qualified clinician. Do not use Pink Lull to make medical decisions.
Who we are
Pink Lull 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 location, no contacts, no calendar.
- No third-party servers of any kind. Your Health data is never transmitted to us or to anyone else.
HealthKit (read-only)
Pink Lull requests read-only access to the specific Apple Health categories you select on the permission screen. Typical categories are steps, active energy, heart rate variability, and sleep, but you may grant only a subset. The app reads today's values in-process to write the bedtime story.
Pink Lull never writes to Apple Health. The app does not create, modify, or delete any Health sample. The app does not share Health data with anyone, including us, Apple beyond the on-device HealthKit API, or any third party.
You can revoke any HealthKit category at any time in iOS Settings → Health → Data Access & Devices → Pink Lull. Revoking access means new sleep stories cannot be generated; sleep stories that already live on your device remain playable.
A note about an iOS quirk: Pink Lull's Info.plist declares NSHealthUpdateUsageDescription because Apple's upload tooling requires it whenever NSHealthShareUsageDescription is present. The purpose string for the update key makes the truth explicit: the app does not actually write to Health.
What stays on your device
- Sleep story entries (the story text, the audio filename inside the app's sandbox, the duration in seconds, the summary of which Health metrics were used, and the creation timestamp). Stored in on-device SwiftData and the app's audio sandbox.
- 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 Foundation Models (Apple Intelligence)
The bedtime story is written by Apple's on-device Foundation Models, accessed through the public LanguageModelSession API on iOS 26. The model executes locally on your iPhone's Neural Engine. Your Health values are passed to the model in-process and never leave the device. The app does not use Apple's Private Cloud Compute fallback for this feature.
Story generation is available only on Apple Intelligence-capable devices (iPhone 15 Pro, iPhone 16, or newer) running iOS 26 or later. On older devices the app does not generate new stories.
Audio (AVSpeechSynthesizer)
Once the story text is written, Pink Lull uses Apple's built-in AVSpeechSynthesizer to render it to audio at a slow, calm speech rate. The synthesis runs on-device. The rendered audio file is saved inside the app's sandbox so you can play it back later. It is not uploaded anywhere.
In-app purchases
The free tier lets you generate up to three sleep stories lifetime. Pink Lull Pro unlocks unlimited sleep stories, a year-long audio archive, and a Lock Screen widget.
If you choose to subscribe (Monthly, Annual) or buy the Lifetime unlock, 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 Lull 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 Lull 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 Lull 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. To revoke HealthKit access without deleting the app, use iOS Settings → Health → Data Access & Devices.

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.
