Privacy Policy

Short version

Pink Vein lets you type three numbers (systolic, diastolic, pulse) plus an optional memo. Every entry stays on your device via SwiftData. The app does NOT use HealthKit, does NOT read from any sensor, and does NOT diagnose any condition. There are no accounts, no analytics, and no servers. The only network calls the app makes are to Apple's StoreKit when you choose to subscribe or unlock the Lifetime tier.

Not a medical device. Pink Vein does NOT diagnose, treat, cure, or prevent any condition. The numbers come from whatever monitor you use; the app is a journal, not a sensor. For health concerns, consult a qualified clinician. Pink Vein is intended for personal record-keeping only and is not a substitute for professional medical advice, diagnosis, or treatment.

Who we are

Pink Vein 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 HealthKit, no Health data, no integration with any health framework.
• No on-device or cloud language model. The app contains no LLM.
• No microphone, no camera, no photos.
• No location, no contacts, no calendar.
• No usage data sent off the device.

Permissions used

None. Pink Vein requests no iOS permissions. It does not prompt for Health access, notifications, microphone, camera, location, contacts, calendar, or any other sensitive resource.

What stays on your device

• Your ReadingEntries: systolic, diastolic, pulse, an optional memo, and the createdAt timestamp. Stored in on-device SwiftData.

All of the above lives on your device and never leaves it. Uninstalling the app deletes it.

Free vs Pro

The Free tier shows the last 7 days of your history. Pink Vein Pro unlocks the full year of history, the trend chart PDF export, and the Lock Screen widget.

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 Vein 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 Vein 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 Vein 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.
