Privacy Policy

Humble Media · Effective March 19, 2026

Privacy is a core design principle of Humble Zen — not an afterthought. On-device transcription means your audio never leaves your phone. Here's exactly what we collect, what we don't, and why.

1. What We Collect

Humble Zen collects only what's necessary to provide and improve the service:

  • Account data — When you sign in with email, Google, or Apple, we store your user ID, email address, and display name via Firebase Authentication (Google Cloud). Anonymous accounts are created automatically on first launch and store no personal identifiers.
  • Note content — Your transcripts, summaries, flashcards, quiz results, and other note data are stored in Firestore (Google Cloud) when you are signed in, so they sync across devices. This data is associated with your user ID.
  • Purchase data — In-app purchase status and credit balances are managed by RevenueCat, a third-party payment infrastructure provider. RevenueCat receives your App Store receipt and purchase history to verify and fulfill your purchase. See RevenueCat's privacy policy for details.
  • Usage data — We may collect anonymous, aggregated usage analytics to understand how the app is used and improve the product. This data cannot identify you.

2. What We Never Collect

  • Your audio recordings — Transcription runs entirely on-device using an embedded Whisper model. Your audio files are never uploaded to Humble Media servers or any third-party transcription service.
  • Voice or biometric data — We do not collect, store, or analyze your voice for any purpose beyond on-device transcription.

3. AI Features

When you use AI-powered features — summaries, flashcards, quizzes, chat, or cheat sheets — the text of your transcript is sent to our AI processing provider (Cloudflare Workers AI) to generate the result. Only the transcript text is transmitted. Your audio is never sent.

Each AI action consumes credits. The transcript text sent for AI processing is used solely to generate the requested output and is not retained or used to train AI models.

4. Data Storage and Sync

Your notes are stored locally on your device using SwiftData. When you are signed in, they are also synced to Firestore (Google Cloud / Firebase) so you can access them across devices and protect against data loss.

Firebase Storage is used to store audio file references associated with your account. All Firebase data is stored in Google Cloud infrastructure and subject to Google's data security standards.

5. How We Use Your Data

We use the data we collect to:

  • Provide and sync the Humble Zen service across your devices
  • Process in-app purchases and manage AI credit balances
  • Respond to support requests
  • Improve the app through anonymous usage analytics

6. Data Sharing

Humble Media does not sell your personal data. We share data only with the third-party service providers necessary to operate the app:

  • Firebase (Google) — Authentication, database, and storage
  • Cloudflare Workers AI — AI feature processing (transcript text only)
  • RevenueCat — In-app purchase management

We may disclose information if required to do so by law or in response to a valid legal request.

7. AI Training

Humble Media does not use your notes, transcripts, or any personal data to train AI models. Your content is yours.

8. Data Retention and Deletion

Your data is retained as long as your account is active. You can delete individual notes within the app at any time. To delete your account and all associated data, contact us at hello@humblezen.app and we will process the deletion promptly.

9. Your Rights

You have the right to access, correct, and delete your personal data. If you have questions or requests regarding your data, contact us at hello@humblezen.app.

If you are located in the European Economic Area, you may have additional rights under GDPR, including the right to data portability and the right to lodge a complaint with a supervisory authority.

10. Children's Privacy

Humble Zen is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

11. Changes to This Policy

We may update this privacy policy from time to time. When we do, we'll update the effective date above. We encourage you to review this page periodically. Continued use of Humble Zen after changes are posted constitutes your acceptance of the revised policy.

Our bottom line: your audio never leaves your phone, your notes are yours, and we don't sell your data. We built Humble Zen to earn your trust — and that starts with being honest about how your data is handled.
