What Patterns stores
Patterns stores journal entries, OCD event notes, obsession or compulsion category, distress ratings, strategy notes, dates, timestamps, and basic app preferences such as theme and onboarding completion.
Local storage
Patterns does not create accounts, upload journal entries or OCD records, provide cloud sync, or include advertising and third-party analytics. The app keeps a small set of product-usage counters and recent events on your device to improve the first-session experience; these are not uploaded as remote telemetry. Patterns does not sell, share, or send your entries to third parties. Manual exports go only where you choose to save them.
Purchases
Apple App Store and Google Play process in-app purchases under their own terms. Patterns receives the purchase result needed to unlock Pro and stores that entitlement locally. Patterns does not use purchase information for advertising, analytics, or profiling, and your journal and OCD records are never included.
Export and import
Manual export creates a JSON backup file in the location you choose. After export, that file may be handled by your device, cloud storage, email, or another document provider. Importing a backup replaces the current local journal and OCD entries in the app.
Health and safety
Patterns is for personal reflection and self-tracking. It does not diagnose, treat, prevent, or cure any condition, and it is not a replacement for care from a qualified clinician.
Data deletion
You can delete individual OCD events in the app. Settings also includes a Wipe all data action that deletes local journal entries, OCD events, and app preferences from the device.
