Terms of Service

1. Agreement to Terms

By using Rhythm ("the Service"), you agree to these Terms of Service. If you don't agree, that's okay, but you won't be able to use Rhythm.

We may update these terms from time to time. For material changes, we'll give you at least 30 days notice via the email associated with your account (see Section 11).

2. Eligibility

You must be at least 18 years old to use Rhythm. If you're between 13 and 17, you can use Rhythm with a parent or guardian's permission and supervision.

Important: Rhythm is designed for use by adults. It is a tool for parents and caregivers to track information about children, not for use by children. We don't knowingly collect personal information from children under 13.

3. Your Account & Security

When you create an account, you're responsible for keeping your login credentials secure. Use a strong, unique password. If you think someone has accessed your account without permission, let us know immediately.

If you invite others to your household, you're vouching for them. Choose your household members carefully. They'll have access to your shared data.

4. Your Data

You own your data. The feeding times, sleep logs, and notes you enter belong to you. We don't sell it, mine it, or use it to train AI models.

We need a limited license to operate the service: storing your data, syncing it between your devices, and displaying it back to you. That's it. You can export all your data anytime in JSON format, no subscription required.

When you delete your account, we delete your data. See our Privacy Promise for the full picture.

5. Subscription & Billing

Rhythm has a free tier that includes unlimited event logging and local storage. Premium features like household sync require a paid subscription.

We use Stripe to process payments. Your payment details go directly to Stripe. We never see or store your full card number.

Subscriptions renew automatically. You can cancel anytime from your account settings. When you cancel, you keep access until the end of your billing period.

6. Acceptable Use

Please don't:

Use Rhythm to store or transmit illegal content
Attempt to access other users' data without permission
Reverse engineer, decompile, or disassemble the service
Use automated systems (bots, scrapers) to access the service
Interfere with the service's operation or other users' access
Use Rhythm for any commercial purpose without our written consent

We reserve the right to suspend or terminate accounts that violate these rules.

7. Household Sharing

When you create a household and invite members, all members share access to the household's data. This is by design. Coordinating care requires shared information.

All household members are jointly responsible for the data in the household. If someone in your household violates these terms, the whole household may be affected.

You can leave a household at any time. If you're the household owner, you can remove members or delete the household entirely.

8. Disclaimers

Rhythm is not medical advice. We're a tracking tool, not healthcare providers. Our suggestions (like wake windows or nap timing) are based on patterns in your data, not medical expertise. Always consult your pediatrician for health-related decisions.

The service is provided "as is" without warranties of any kind. We do our best to keep Rhythm running smoothly, but we can't guarantee it will be available 100% of the time or that predictions will be accurate.

Every baby is different. What our algorithm suggests may not work for your child. Trust your instincts. You know your baby better than any app.

9. Limitation of Liability

To the maximum extent permitted by law, Rhythm's liability is limited to the amount you've paid us in the 12 months preceding any claim.

We're not liable for indirect, incidental, or consequential damages, including lost data, lost sleep (sorry, we can't help with that one), or decisions made based on our suggestions.

10. Termination

You can leave anytime. Delete your account from the settings page, and we'll remove your data.

We can terminate or suspend your account if you violate these terms, engage in illegal activity, or abuse the service. We'll try to give you notice, but in cases of serious violations, we may act immediately.

11. Changes to Terms

We may update these terms to reflect changes in the service or legal requirements. For material changes, we'll email you at least 30 days before they take effect.

If you disagree with updated terms, you can close your account before they take effect. Continuing to use Rhythm after changes go live means you accept the new terms.
