Help & support

Support and privacy contact for Cotton, provided by Moimaere OU: destek@sirada.com. Please include your app version, iOS version and a description of the issue. Avoid attaching Health data or audio unless you intend to share it.

Missing sleep or recovery readings

Wear your compatible watch or band overnight, allow it to sync, and check that its records appear in Apple Health. Enable the desired read permissions and choose the correct sleep source in Cotton. Sleep stages and recovery metrics appear only when your source provides enough data.

Tracking with your iPhone

Open Today → Track and choose where the phone sleeps. By your pillow, place it on the mattress near your pillow for a sleep estimate, movement and sounds; on the nightstand it listens for snoring and talking only. Charging overnight is recommended. If tracking cannot start, allow the microphone in iPhone Settings → Cotton. Quiet wake time is hard to notice from a phone, so a wearable gives the more complete night; when you use both, Cotton combines them into one morning score.

Backup and account

Use Sign in with Apple on the entry screen. Existing local profiles are preserved. Cloud backup is optional and off by default. Enable it in Settings → Settings → Account to synchronize your private records. Phone-tracked nights and clips stay on the iPhone. Offline edits retry when connected. To remove a cloud copy, turn backup off and complete removal; other devices with backup on can upload again. Account deletion is available in Settings → Settings → Account.

Subscriptions and purchases

Use Restore purchases with the Apple Account used to purchase. For renewal or cancellation, open Apple subscription settings. For refund requests, use Apple’s Report a Problem. Deleting Cotton or your app account does not cancel a subscription. Lifetime access is a non-recurring purchase. No free trial is offered.

Experiments and exports

Experiments compare your own observations and are not medical research or proof of causation. Export app-owned data from Settings → Settings before account deletion. Apple Health originals remain in Health.
