Sojourn is committed to protecting your privacy. This policy explains what information we collect and how we use it.
Information We Collect
Account Data
When you sign in with Apple, we store:
- Your Apple ID token (for authentication)
- Your display name (if provided by Apple)
- Your email address (may be an Apple relay address)
You can use Sojourn without signing in. Anonymous sessions are created automatically and do not require any personal information.
Story Data
Your reading progress, choices, and listener profile preferences are stored on our servers (hosted by Supabase) so they can sync across your devices. This data is private to your account and is not shared with anyone.
Generated Content
Story sessions are generated in real-time using AI (Claude by Anthropic). The prompts sent to the AI include your story context and listener preferences but do not include your name, email, or any personally identifying information.
Local Data
App preferences and reading progress are stored locally on your device using standard iOS storage.
Analytics Data
We use Mixpanel to collect app usage data. This helps us understand which features are used and how to improve the app. Analytics data includes:
- Feature usage events (e.g. session started, session completed, choice made)
- App name and version
Analytics data is associated with an anonymous identifier. It does not include:
- Your name, email address, or Apple ID
- Your story choices or reading history
- Any generated story content
We do not use advertising identifiers (IDFA) or track you across apps.
See Mixpanel’s Privacy Policy for details on how they handle data.

Supabase
We use Supabase for authentication, data storage, and serverless functions. Supabase’s infrastructure is hosted on AWS. See Supabase’s Privacy Policy for details.
