Privacy Policy

Last updated February 20, 2026

Belay ("we," "our," or "the app") is a pregnancy and postpartum companion app for partners. Your privacy matters to us. This policy explains what data we collect, how we use it, and your rights.

How We Use Your Data

What We Don't Do

Where Your Data Lives

Your data is stored securely on Supabase (cloud infrastructure hosted on AWS in the United States). Data is encrypted in transit (HTTPS/TLS) and at rest. Access to the database is restricted by row-level security policies, meaning you can only access your own data.

Some data (contraction sessions, mood check-ins, checklist progress) is also stored locally on your device so the app works when you don't have an internet connection.

Third-Party Services

We use the following services to operate Belay. Each has their own privacy policy:

Service Purpose
Supabase Database and authentication
Anthropic (Claude API) AI-powered Ranger responses
PostHog Anonymous usage analytics
Expo / EAS App delivery and push notifications
Google (OAuth) Sign-in with Google
RevenueCat Subscription management and purchase processing
Sentry Crash reporting

We do not share your personal data with any services beyond what is necessary to operate the app as described above.

Sensitive Data

We understand that some data in Belay is particularly personal:

Your Rights

You can:

Data Retention

Security

Children's Privacy

Belay is designed for adults (partners and parents ages 18 and older). We do not knowingly collect data from anyone under 13 years of age. The baby-related data in the app (name, birth date) is provided by the parent, not the child. If you believe a child under 13 has created an account, please contact us and we will delete it immediately.

Changes to This Policy

We may update this policy from time to time. If we make significant changes, we will notify you through the app or via email. The "last updated" date at the top always reflects the most recent revision.

Contact Us

If you have questions about this privacy policy, your data, or anything else:

Belay is an independent app built by a solo developer. We are not affiliated with any hospital, medical provider, insurance company, or government agency.
