SleepShred is designed so that your data stays on your device. This page explains exactly what the app does and does not do.

What we collect

Nothing is sent to us. Nights, days, caffeine, weight, screening answers, experiments and notes are stored locally on your iPhone in the app's private database. There is no SleepShred account and no analytics SDK.

Apple Health

If you choose to connect Apple Health, SleepShred reads sleep analysis, resting heart rate, HRV, respiratory rate, blood oxygen, dietary caffeine, body mass, body fat, waist, steps, active energy and dietary energy/protein — only to display them and compute your own trends on-device. Nights you log manually can optionally be written back to Health. You can revoke access at any time in the Health app; the app works fully without it.

Microphone

The bedroom noise meter reads the live sound level only while you run it. Nothing is recorded, saved or transmitted.

Notifications

Reminders (morning check-in, caffeine cutoff) are scheduled locally on the device.

Export & deletion

You can export your data as CSV at any time and delete everything from Settings. Deleting the app deletes all data.

Third parties

The website and app do not use advertising or tracking cookies. Links to PubMed open in your browser.

Not medical advice

SleepShred is an educational self-tracking tool, not a medical device. Screening questionnaires are not diagnoses. If a score is elevated or you feel unwell, talk to a clinician.
