Your cycle, symptom, and journal logs live in private iCloud—not on Red Tent servers. Learn what syncs across devices, what stays on this device only, where Settings states the boundary, and what happens when iCloud is unavailable.
🔒Health data you log in Red Tent syncs through your Apple ID's private iCloud database—not Red Tent company servers. Optional Research Data Sharing is a separate, revocable choice.
What syncs through your private iCloud
- Cycle and period anchors, daily logs, and the symptom and life-factor values you save each day.
- Journal entries from Add Notes and other health-related records tied to your tracking.
- Tracking preferences, check-in configurations, profile and account settings, and notification preferences.
- Each save writes to Core Data on your device and mirrors to your iCloud Private Database (iCloud.com.redtentpmdd.RedTentPMDD).
- Only your Apple ID can access that private database—Red Tent cannot read or export your private iCloud data from the cloud.
What stays on this device only
- Bundled education articles and other seeded resource content ship with the app and stay in a separate local store.
- Community feed caches and related on-device copies used for faster loading do not sync through your private iCloud.
- That local store has no CloudKit mirroring—content may refresh when you open Resources or Community again.
- Your logged health data is unaffected when local caches refresh; only the editorial and feed copies are device-local.
Sync across your devices
- Sign in with the same Apple ID on each iPhone or iPad where you use Red Tent PMDD.
- After the initial CloudKit import on a new device, changes you make on one device appear on your other signed-in devices when iCloud is available.
- Offline logging still saves on the device first; sync catches up when the device reconnects to iCloud.
Signing in with a different Apple ID keeps each account's health data in that Apple ID's private iCloud. See Switching Apple ID.
Where Settings says this
01
Settings
On the Home tab, tap the gear in the date header. The navigation title reads Settings.
02
Research Data Sharing
In the Data Management section, this row sits above Your Data—optional research opt-in, not daily iCloud sync.
03
Your Data
The row below shows the subtitle Import · Export · Delete.
04
Footer
Below both rows, read: Your data is stored securely on your device and synced privately with your iCloud.
When iCloud is unavailable
- Before sign-in — Red Tent checks CloudKit account status and blocks sign-in until iCloud is ready on the device. See Sign in with Apple.
- While signed in — if iCloud becomes unavailable, Red Tent signs you out automatically for data safety.
- Health data already in your private iCloud is not deleted. Sign in again with the same Apple ID when iCloud is available.
For step-by-step fixes—welcome-screen status messages, sign-in failure alerts, and device Settings checks—see iCloud or Apple ID errors.
Research sharing is separate
- Research Data Sharing is optional anonymized contribution—not the same path as daily iCloud sync. See Research data sharing settings.
- Daily tracking still syncs through your private iCloud whether or not research sharing is on.
- Revoke research sharing anytime from Settings without affecting your private iCloud logs.
✦Your Data is for export, import, and selective delete on your device—a backup path, not iCloud sync or research consent. See Your data in Settings.
