Privacy Policy

Short version

Pink Echo lets you type a one-to-three-line reflection seed once a day. Apple's on-device Foundation Models expand the seed into an 80–120 word reflective letter, and AVSpeechSynthesizer synthesizes that letter using the Personal Voice you previously set up in iOS Settings. The seed, the letter, and the synthesized audio are saved as today's entry 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 Echo 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. Pink Echo never records audio. It only synthesizes the letter using a Personal Voice you already set up in iOS.
• No camera, no photos, no location.
• No contacts, no calendar.
• No HealthKit, no Health data.

Personal Voice authorization

Pink Echo synthesizes today's letter using the Personal Voice feature introduced in iOS 17. Personal Voice is set up by you, in iOS Settings, by recording samples on your own device. Pink Echo does not record those samples and never has access to the underlying voice model — it only asks the system to play back synthesized speech in the voice you chose.

The first time you tap Speak, Pink Echo calls AVSpeechSynthesisVoice.requestPersonalVoiceAuthorization so the system can ask whether you want to allow this app to use your Personal Voice. You can revoke that permission at any time in iOS Settings → Accessibility → Personal Voice. If no Personal Voice is set up or authorization is denied, Pink Echo falls back to a standard system voice; the letter still saves either way.

What stays on your device

• Your echo entries (the one-to-three-line seed you typed, the 80–120 word letter the on-device model produced, the synthesized audio bytes, and the created-at timestamp). Stored in on-device SwiftData with the audio 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.
• 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 everything Pink Echo has stored.

On-device language model (Apple Intelligence)

The reflective letter is generated by Apple's on-device Foundation Models, accessed through the public LanguageModelSession API on iOS 26. The model executes on your iPhone's Neural Engine. The seed you typed is passed to the model in-process and never leaves the device. Pink Echo does not use Apple's Private Cloud Compute fallback for this feature.

Letter generation is available only on Apple Intelligence-capable devices running iOS 26 (iPhone 15 Pro, iPhone 16, or newer with the A17 Pro chip or later). On unsupported devices the entry still saves with the seed and the synthesized speech of the seed itself, but the letter expansion step is skipped.

Speech synthesis

Speech is produced by Apple's AVSpeechSynthesizer using the Personal Voice (or fallback system voice) on your device. Synthesis runs on-device. The audio buffer is captured to a local file and stored alongside the letter. Pink Echo does not stream audio to any server and does not use any third-party text-to-speech service.

Lock Screen widget

Pink Echo Pro includes a Lock Screen widget that shows today's letter count or the date of the most recent entry. The widget reads only the count and the timestamp from an App Group container on your device. No letter text and no audio is exposed on the Lock Screen, and nothing is sent off the device for the widget to function.

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 Echo 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 Echo 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 Echo does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke Personal Voice authorization, use iOS Settings → Accessibility → Personal Voice. 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.
