Privacy Policy

Last Updated: 22/04/2026

1. Overview

Matt is designed with privacy as a core principle. Audio is never sent to external servers and transcription happens entirely on your device. The transcription process itself does not transmit any user data outside the device. We do not require an account: no email, name, or personal information is collected. The sections below describe exactly which data leaves your device, when, and why.

2. Key Privacy Points

• Audio never leaves your device — transcription is performed on-device and no user data is sent outside during the transcription process.
• Transcribed text is sent to our servers only in two cases: when you explicitly request a summary, or — for automatic title generation — only when you save the audio inside the app. It is not linked to any personal identity.
• No user accounts — no email, name, or personal information collected.
• Firebase Analytics collects only anonymous usage data.
• RevenueCat handles payments — purchase data is processed through the Apple App Store.
• All your data stays on your device — no proprietary cloud backups.

3. RevenueCat (Subscription Management)

Purpose: manages in-app subscriptions and purchases.

Data transmitted: subscription status (free/Pro), purchased plan type (weekly/yearly/lifetime), free trial eligibility, purchase history, billing issues.

User identifier: anonymous (generated by RevenueCat).

See the RevenueCat Privacy Policy for details.

4. Firebase Analytics (Google)

Purpose: tracks app usage events to improve the product.

Data transmitted: anonymous behavioral events with no personally identifiable information.

Tracked events include:

• Onboarding completed / step reached
• Paywall shown (with reason), dismissed, plan selected
• Purchase started / completed
• Transcription completed (duration in seconds + language)
• Share Extension opened / closed
• Actions used (copy, save, translate, summarize)

Identifier: anonymous Firebase Instance ID.

See the Google Privacy Policy for details.

5. Supabase + OpenAI (Summaries and Auto Titles)

Purpose: generates summaries and automatic titles for your transcriptions.

When it is used:

• Summaries: only when you explicitly request a summary.
• Automatic title generation: happens automatically only when you save the audio inside the app. If you do not save the audio, no title generation is performed and no text is sent.

Data sent to Supabase (intermediate server):

• Transcribed text (max ~120,000 characters for summaries, max 1,500 for titles)
• Transcription language
• Requested level of detail

Supabase then forwards the text to OpenAI for processing.

Authentication: anonymous (no account, no email).

Note: the transcribed text is NOT associated with any personal identifier.

See the OpenAI Privacy Policy for details.

6. Apple Speech Framework (Transcription)

Processing: entirely on-device.

No audio or text data is transmitted to external servers during transcription.

7. Apple Intelligence / FoundationModels (Alternative Summaries)

Processing: entirely on-device on iOS 26+.

Used as a local fallback when there is no internet connection or OpenAI is unavailable.

No data is transmitted.

8. Local Data (Never Transmitted)

• All transcriptions, audio recordings, summaries, and translations are saved only on your device (SwiftData).
• Preferences, language settings, and Pro status are stored locally (UserDefaults).

9. Permissions Requested

• Microphone — to record audio.
• Speech Recognition — to transcribe audio.
• Notifications — optional, used for feedback reminders.

10. User Rights

Since Matt does not collect personally identifiable data and does not require an account, there are no personal records to access, correct, or delete on our side. Anonymous data sent to RevenueCat, Firebase, Supabase, or OpenAI is governed by their respective privacy policies linked above.
