What Shuen keeps
Version 2026-10-08-beta-v1. These periods apply to the invited Shuen beta. Cloud history and sync diagnostics apply only if you turn them on.
| Information | Retention |
|---|---|
| Saved daily health summaries, Sleep, Readiness and Load results, compact calculation context, profile settings, and any corrections, habits or journal entries you choose to keep | On your iPhone until you delete the relevant records, reset the app or remove the app. We do not promise to recover data lost with the phone. |
| Minute Body Activation, five-minute heart-rate charts, sleep-stage intervals and detailed workout timelines | Up to 90 days in the app. |
| Original sensor and history frames, per-second heart-rate, beat interval, movement and temperature detail | Up to 90 days on the phone; no routine raw cloud upload. |
| Compact live inputs and per-second movement summaries used to fill recent gaps | Up to 14 days on the phone. |
| Battery, charging, signal and connection state | Current operation only; no cloud series. |
| Optional cloud history: supported summaries, scores with their calculation context, measurements you choose to keep and your entries | In your Shuen account while it is active, intended for up to ten years after you last use or renew it. Automatic deletion for inactivity is not switched on during the beta. Withdrawing cloud consent or deleting your account removes it. |
| Optional cloud copies of recent detail (charts, sleep stages, workout timelines) | Up to 90 days. The raw band stream is not routinely uploaded. |
| Cloud database backups | Our provider keeps seven days of database backup history. |
| Optional sync diagnostics (app and connection events, no health data) | 7 days, then deleted. |
| App-generated export package | Removed from the app within 24 hours and when you leave the export screen. A copy you save or share is under your control. |
Scores and future changes
Saved scores reflect the calculation used when they were created. A later algorithm may give a different number; we will not silently rewrite old results. We keep compact explanation and method information where available, but short-lived raw detail cannot always be used to recalculate an old day. Exact stored measurements may evolve. Before reducing an existing history commitment, we will explain the affected fields, old history, timing, and export or other options.
Deletion and lost devices
Deleting or withdrawing consent stops the relevant processing and removes the applicable information. A deletion made while offline is applied when the phone reconnects. We cannot erase a phone that stays permanently offline or copies you exported. Only history confirmed as saved to your account can be restored on another phone; keep a separate export while testing.
