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

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

5) Storage, security & retention
