Terms of Use
Last updated: September 12, 2026By using Tonight you agree to these terms.
The service
Tonight records your sleep with Apple Watch, suggests a bedtime, tries to wake you during light sleep before your chosen latest time, and offers explanations and suggestions generated by software. It is a wellness tool, not a medical device, and it may be wrong. Always keep a backup alarm for anything important.
Your account
You are responsible for the devices you sign in on. You may delete your account at any time in the app. We may suspend accounts that abuse the service (for example automated or excessive AI requests).
Acceptable use
Do not attempt to access other users' data, reverse engineer the service, or use it to harm others. Family sharing is for people who have agreed to share with each other.
Availability and changes
The service is provided as is, during a testing period, and may change or be interrupted. Features that depend on Apple platform permissions (Sign in with Apple, Screen Time) become available as Apple grants them.
Liability
To the extent permitted by law we are not liable for indirect damages, missed alarms, or decisions made based on the app's estimates.
