Short version

Pink Cat listens for a short cat sound through the iPhone microphone while you hold the record button. It classifies the sound on-device using Apple's built-in SoundAnalysis framework (the version1 system classifier recognizes labels such as cat, cat_meow, and cat_purr), measures the dominant frequency with Apple's Accelerate framework (vDSP), and then asks Apple's on-device Foundation Models for a 1-2 sentence plain-English translation of what your cat is likely saying. The short m4a audio clip, the sound-type label, the dominant frequency in hertz, the duration, the on-device translation text, and any context note you type 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 Cat 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. Pink Cat never opens the camera.
• No Photos library access. Pink Cat does not read or write to your Photos library.
• No location, no contacts, no calendar.
• No HealthKit, no Health data.
• No speech recognition. Pink Cat does not transcribe human speech and is not designed to capture voices.
• No cloud LLM calls. The translation is generated entirely on your iPhone's neural engine using Apple Foundation Models.

Microphone permission

Pink Cat requests Microphone access (the NSMicrophoneUsageDescription permission) so that Apple's AVAudioEngine can capture a short audio buffer while you hold the record button. The microphone is opened only while you are holding the button on the capture screen and is released as soon as you let go.

The captured buffer is fed to Apple's SNClassifySoundRequest to detect whether it sounds like a meow, a purr, or another cat call, and to a real FFT (vDSP_fft_zrip) to find the loudest frequency bin. Pink Cat does NOT run speech recognition, voice-print analysis, speaker identification, or any other intelligence intended for human voices.

On-device sound classification

The sound-type classifier is Apple's bundled SNClassifierIdentifier.version1, which ships with iOS and runs entirely on your device. Pink Cat reads the top-confidence label (for example cat_meow or cat_purr) along with its confidence score. No audio is uploaded to any classifier service, and no third-party model is contacted.

On-device translation (Apple Foundation Models)

Pink Cat uses Apple's LanguageModelSession API from the FoundationModels framework (iOS 26+, Apple Intelligence) to turn the sound type, dominant frequency, duration, and your optional context note into a 1-2 sentence translation of what your cat is likely saying. The prompt is handed to Apple's on-device large language model, which runs on your iPhone's neural engine. The reply is delivered back to the app and saved with the entry.

Apple has documented that Foundation Models inference happens locally on supported devices and does not require a network connection. Pink Cat does not enable Private Cloud Compute or any opt-in cloud routing. We do not see your prompts, your translations, or your audio because they never touch a server we control.

Pink Cat requires an Apple-Intelligence-capable device with Apple Intelligence enabled in Settings: iPhone 15 Pro, the iPhone 16 or 17 series, or an M1+ iPad on iOS 26 or later. On unsupported devices the translation step displays a clear notice and is disabled; the classifier and frequency readout still work, but no translation text is generated.

What stays on your device

• Your cat entries (the short m4a audio clip, the sound-type label such as cat_meow, the dominant frequency in hertz, the duration in seconds, the 1-2 sentence translation produced by Foundation Models, an optional context note you typed, and the created-at timestamp). Stored in on-device SwiftData with the audio bytes held as external storage.
• How many lifetime translations you have used (used to enforce the free tier of three lifetime translations). Stored in UserDefaults.
• Whether the introductory cards and the day-three gift screen have been acknowledged.

The audio clip, the classifier output, and the translation are written only to Pink Cat's private container. The app does not upload the audio anywhere and does not save it to any shared location.

All of the above lives on your device and never leaves it. Uninstalling the app deletes everything Pink Cat has stored.

Year cat book PDF export

Pink Cat Pro can render your year of entries into a PDF keepsake on your device. The PDF is built locally using Core Graphics from your own saved entries; nothing is sent off the device to render it. You choose where to save or share the PDF using the standard iOS share sheet.

Lock Screen widget

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

In-app purchases

The free tier includes three translations lifetime. 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 Cat 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 Cat 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. Note that the on-device language model may, like any LLM, produce unpredictable text; parents should supervise children using generative AI tools.

Your rights

Because Pink Cat does not collect data, there is nothing for us to export, correct, or delete on your behalf. To revoke Microphone permission, use iOS Settings → Privacy & Security → Microphone. 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, optional 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.
