Terms of use
Tiny Rhythm is a planner for tired parents. It is not a medical device.
Last updated August 31, 2026.
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. Optional iCloud sync and caregiver sharing use your Apple account. We do not run a server that receives baby logs. See the privacy policy for the full picture, including what happens if you lose your phone.
Waitlist
Until Nicolas approves a send path, the website waitlist saves on your device only. If a first-party waitlist is later approved, we will store your email and the optional “what do you wish the expensive apps did” answer so we can send one confirmation when the App Store listing is live. We will not sell those emails or use them for third-party ads.
Premium
Core predictions and logging stay free. Premium is optional: US$3.99 a month or US$24.99 a year, billed by Apple. Cancel in your App Store settings. Apple’s terms apply to the purchase.
Coming soon
The App Store listing is not live yet. This site does not offer a download that 404s. Join the waitlist instead.
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.
