Why Comma exists

We built Comma after seeing a constant stream of news about privacy breaches. We believe that period tracking apps are useful tools, and that you should be able to trust them not to pass around your most sensitive data.

Why it's different

🔒

Private by design

Built from the ground up with privacy in mind. No tracking, no analysis, no third-party data sharing. Payments are handled securely and anonymously.

✨

No rough edges

Cozy theming and a simple, intuitive interface. Everything just works.

🔔

Early warnings

Comma calculates when your next period is expected and notifies you beforehand so you can be prepared.

Is Comma right for you?

✓ You want to keep your information super private

✓ You want something with a more human than clinical feeling

✓ You want something built by a small trustworthy team rather than a big corporation
