Terms of use
Tiny Rhythm is a planner for tired parents. It is not a medical device.
Last updated October 12, 2026.
Tiny Rhythm is published by Nicolas Hesson.
By using tinyrhythm.app or the Tiny Rhythm iOS app, you agree to these terms. If you do not agree, do not use them.
What this is
Tiny Rhythm helps you log sleep and see the next nap or bedtime window from today’s wake windows. It is general scheduling support. It does not diagnose, treat, or prevent any condition, including SIDS. It does not replace your clinician.
Who it is for
The app is for parents and caregivers. Children do not create accounts. You are responsible for the information you enter about your child.
Your data
The app is local-first. When iCloud is available, owned records and photos can sync automatically to your private iCloud using your Apple account, independently of caregiver invitations. Invited caregivers access shared records through Apple CloudKit. We do not run a server that receives baby logs. See the privacy policy for the full picture, including device backups and exports.
Settings → Delete all data clears local routine records and queues deletion of owned iCloud data and leaving joined shares. Cloud cleanup may remain pending; reopen online with the same iCloud account so it can finish. Deletion cannot recall exports, screenshots or other copies saved outside the app, or device backups. Deleting data or uninstalling does not cancel Premium.
Waitlist
The current website waitlist saves your email, optional question and submission time only in that browser’s local storage. It does not send those fields to us, register you with an email service or enable us to send a launch notification. Entries have no automatic expiry and remain until the browser removes them or you clear Tiny Rhythm website data in your browser settings. We will not sell those emails or use them for third-party ads. See the privacy policy for the separate website analytics information.
Premium
Core sleep predictions and logging stay free. Premium is an optional auto-renewable subscription with monthly and annual options, billed by Apple. The App Store shows the local price and any eligible introductory offer before purchase. Payment is charged at confirmation or after an eligible free trial unless cancelled. The subscription renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel it in your Apple subscription settings. Apple’s terms apply to the purchase.
Coming soon
Tiny Rhythm is preparing for public release. Public download availability has not yet been confirmed. Contact support for current availability; the current waitlist page does not register you for launch emails.
Acceptable use
Do not misuse the site or app, scrape it, or try to break it. Do not use it to give medical advice as if it were a clinician.
No guarantees
Every baby is different. We do not promise more sleep, fewer wakes, or any health outcome. The service is provided as-is.
Liability
To the extent the law allows, Tiny Rhythm is not liable for indirect or consequential loss from using a sleep planner. Nothing here limits liability that cannot be limited under applicable law.
Law
These terms are governed by the laws of British Columbia, Canada, without regard to conflict-of-law rules.
