Privacy Policy
Last updated: October 2026
Short version: EchoChamber is a local-first journaling app. Your notes never leave your device unless you explicitly choose to sync them. We do not have servers that store your journal content. We do not read, sell, or share what you write.
What We Collect
Nothing by default. EchoChamber does not require an account. You can use the entire app without providing any personal information. No email, no name, no device identifier is sent to any server.
Your Data Stays on Your Device
All journal entries, messages, media, and settings are stored locally on your device. This data is not transmitted to us or any third party.
- No cloud sync of journal content
- LAN sync is peer-to-peer between your own devices only
- Encrypted export goes wherever you choose — not to us
Optional Cloud Services
Some features are optional and require an account:
- Cloud sync — syncs encrypted data across your devices via Supabase
- Crash reporting — anonymous diagnostics that help fix bugs (can be disabled)
- In-app purchases — processed by RevenueCat / Google Play / Microsoft Store
These services process data under their own privacy policies. We do not share your journal content with them.
Third-Party Services
If you enable optional features, the following providers may process limited data:
- Supabase — encrypted cloud sync storage (optional)
- RevenueCat — subscription management (optional)
- Sentry — crash reporting (optional, anonymized)
Your Rights
- Export — export all your data at any time, encrypted, to any location
- Delete — delete individual notes or your entire journal locally
- Account deletion — if you created an account, you can delete it entirely
Children's Privacy
EchoChamber does not knowingly collect data from children under 13 (or the applicable age in your region). The app does not require an account, so no age verification is needed.
Changes to This Policy
We will post any changes to this page and update the date above. Continued use of the app after changes constitutes acceptance.
