What Levend keeps
Version 2026-11-04-beta-v16. These periods apply to the invited Levend beta. Cloud history, sync diagnostics and sharing band data for testing 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, and the daily step counts made from them | 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. |
| With Apple Health as your source: the nights, scores, activities, steps and burn worked out from what Levend read | On your iPhone only, like a band's results; never uploaded. The readings themselves stay in Apple Health, which Levend reads again when needed. |
| 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 Levend 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 history: for a 4.0 or 5.0 band, a code for the band you use (made from its serial number, not the number itself) and the date you first paired it | With that band's history in your account. Deleted when you forget the band in the app, delete that band's history, withdraw cloud consent or delete your account. |
| Optional cloud history: your profile answers (birth date, sex, height and weight, blank where skipped), including earlier answers you changed | In your Levend account while cloud history is on and you keep your profile there. Deleted when you stop keeping your profile, withdraw cloud consent or delete your account. |
| Optional cloud history: your entries (check-ins, weight log, daily calories eaten and Nutrition goal), including earlier versions of an entry you changed | In your Levend account while cloud history is on and you keep your entries there. An entry you delete on your iPhone is deleted from cloud history too. Also deleted when you withdraw cloud consent or delete your account. |
| Optional cloud history: each finished day's calorie burn per band (resting and activity calories, the part during logged activities, and measured time) | In your Levend account while cloud history is on and you keep your calorie burn there. Deleted with that band's history or a period you delete, and when you withdraw cloud consent or delete your account. |
| Optional cloud history: each finished day's step count per band (the day's steps, steps per hour and hours not fully recorded) | In your Levend account while cloud history is on and you keep your step counts there. Deleted with that band's history or a period you delete, and when you withdraw cloud consent or delete your account. |
| 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, connection and analysis status, no measurements or scores) | 7 days, then deleted. |
| Optional data shared for testing (each day's band recordings second by second, the app's results and what you logged; or, under an earlier choice, sleep and naps only) | 14 days after upload, then deleted, including the founders' working copies. Deleted within 7 days when you turn the choice off or withdraw health consent. Ends at public launch. |
| App-generated export package | Removed from the app 24 hours after it is prepared, or sooner when you prepare a new one or remove it, or when the data, consent or account it came from changes. 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.
