Privacy Policy

Last updated: September 2025

Privacy at a Glance

What we collect

Encrypted journal entries, limited metadata (dates, word counts, keywords), optional voice recordings for transcription, crash diagnostics, and—only if you sign in—your email.

What we don’t collect

No advertising profiles, no precise location, no third-party ad trackers, no access to your journal content.

Why we collect

To provide core journaling, optional transcription and sync, improve stability, and manage purchases/subscriptions.

Your control

Export, delete entries, or delete your account in the app. We can’t decrypt your journal content.

1) Who we are

Zero Vector Labs LLC (“we”, “us”) operates the Maat Journal app and this website.

Contact: dev@zerovectorlabs.com

Address: 30 N Gould St, STE R, Sheridan, WY 82801, USA

2) Data we process

Journal entries

Your entries are encrypted on your device and, if you enable sync, stored encrypted on our servers. We cannot read your journal content once encrypted.

Voice recordings (optional)

If you use voice journaling, audio is transmitted securely for transcription and then deleted. The resulting text is encrypted on your device.

Metadata

We process limited metadata (e.g., dates, word counts, keywords) to enable features like search, prompts, and insights. Metadata does not include your journal content.

Crash diagnostics

We collect limited technical information when errors occur (e.g., device/app state, timestamps) to improve stability. Journal content is never included.

Account & purchases

If you sign in with Apple or Google, we receive your email. Purchases and subscriptions are handled by the app stores via RevenueCat.

3) Why we use this data

  • Provide journaling, transcription, sync, and AI-assisted features
  • Maintain and improve security and stability
  • Process subscriptions and provide support

We do not sell or use your data for third-party advertising.

4) Legal bases (GDPR)

  • Contract: To provide the app and its features you choose to use
  • Consent: For optional features like voice transcription
  • Legitimate interests: To keep the app secure and reliable

5) Storage, security & retention

We use industry-standard encryption in transit and at rest. Entries are end-to-end encrypted and decryptable only with your recovery phrase, which we cannot access.

  • Voice recordings: deleted after transcription
  • Entries & metadata: kept until you delete them (or delete your account)
  • Crash diagnostics: retained for troubleshooting and then removed

6) Third-party services we use

  • Supabase: encrypted data synchronization/storage
  • Sentry: crash diagnostics (no journal content)
  • RevenueCat & app stores: subscription management
  • Apple / Google Sign-In: optional authentication

These providers act on our instructions and do not receive your journal content.

7) International data transfers

We primarily host services in the EEA. Some providers may process limited data outside your country. When transfers occur, we rely on appropriate safeguards (e.g., Standard Contractual Clauses) to protect your information.

8) Your rights

Depending on where you live, you may have rights to access, export, correct, delete, restrict or object to processing.

  • Use in-app settings to export or delete data (including account deletion)
  • Or contact us at dev@zerovectorlabs.com

We do not sell or share personal information as defined by applicable law.

9) Children

Maat Journal is not intended for children under 13. If you believe a child provided personal data, contact us to delete it.

10) Changes to this policy

We may update this policy. We will post changes here and update the “Last updated” date. If changes are significant, we will notify you in the app.
