Privacy Policy

Overview

Sourdough Journal is a local-first app. Your data - starter logs, feed history, formulas, and photos - lives entirely on your device. We do not operate servers, we do not store your personal information, and we do not sell data to third parties.

Data stored on your device

• Starter profiles and feed logs (stored in a local SQLite database)
• Bread formulas you create or copy
• Photos you attach to feed logs (stored in app sandbox)
• App preferences (stored in device keychain via AsyncStorage)

None of this data leaves your device unless you explicitly export or share it.

Analytics

We use PostHog for anonymous, aggregated usage analytics. This helps us understand which features are used and improve the app. PostHog collects:

• Anonymous event names (e.g. "feed_logged", "formula_created")
• Device type and OS version
• App version

No personally identifiable information is sent to PostHog. You can opt out by disabling analytics in Settings.

In-App Purchases

Sourdough Journal offers a one-time lifetime purchase ("Sourdough+"). Payments are processed entirely by Apple via the App Store. We never see your payment details. Purchase status is verified locally via Apple's StoreKit framework.

Photos

If you attach photos to your feed logs, those images are stored locally in the app's sandbox. They are never uploaded to any server. If you delete the app, the photos are deleted with it.

Push Notifications

If you enable feed reminders, notifications are scheduled locally on your device. No notification data is sent to external servers.

Children

Sourdough Journal is not directed at children under 13 and does not knowingly collect data from children.

Changes to this policy

Any material changes to this policy will be communicated via an app update. The latest version is always available at this URL.
