Local Only, iCloud, and Synk Cloud Sync Explained
A plain-English guide to Synk AI storage modes: local-only tracking, optional iCloud sync, and Pro Synk Cloud sync.
Key takeaways
- Local Only keeps tracking private on the device by default.
- iCloud can support Apple ecosystem sync when users choose it.
- Synk Cloud is the Pro sync option backed by Supabase systems.
- Auth, subscriptions, and AI can exist separately from cloud data sync.
Local-first is the default mental model
Synk AI starts from a local-first model. Goals, activities, logs, journals, and progress history can live on the device as the source of truth.
That matters because users should not need cloud sync before the app becomes useful. They can build a plan, complete activities, journal, and review progress locally.
Local Only is for private device-based tracking
Local Only is the simplest mode. It is useful for people who want private health and wellness tracking on one device and do not need cross-device sync.
This mode supports the core value of Synk AI: daily actions, progress, journaling, and local history without making cloud storage a requirement.
iCloud and Synk Cloud serve different needs
iCloud can be a natural fit for users who want Apple ecosystem sync. Synk Cloud is the Pro option for users who want Supabase-backed sync, realtime behavior, and broader cloud storage features.
Both are optional. The user can choose based on how much portability and sync they need.
- Local Only: private on-device tracking.
- iCloud: Apple ecosystem sync for users who choose it.
- Synk Cloud: Pro cloud sync with account-scoped storage.
- Offline queueing helps local changes sync later when sync is enabled.
Sync is not the same as identity
Supabase can support identity, subscriptions, and AI flows even when Synk Cloud data sync is not enabled. That distinction helps users understand why an account may exist without forcing every piece of personal wellness data into the cloud.
This separation is important for a privacy-conscious health app.
Build the daily plan behind your wellness goals
Synk AI turns goals, activities, journals, and HealthKit-derived progress into a clear daily action plan.
