Local-First Privacy for Sleep Apps: What It Actually Means

When an app says “privacy-first,” the implementation details matter.
Local-first in practice
Local-first means your primary session data is stored on your device.
Benefits:
- Works offline
- Faster access
- Less exposure risk from centralized storage
Optional sync should be explicit
If cloud sync exists, users should be able to opt in and opt out clearly.
For Apple users, CloudKit is a common way to sync across devices while staying inside the Apple account boundary.
What to verify before installing
- Is account creation mandatory?
- Is sync optional or forced?
- Are third-party analytics SDKs present?
- Is there a clear deletion path?
Privacy claims are only useful when behavior matches the claim.
