## What is Comma?

Comma: Privacy First Period Tracking

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 is Comma different to other period apps?

- We built Comma from the ground up with privacy in mind. We don't analyze our users, track any data, or give sensitive information to third parties. Even when accepting payments, we make sure to handle them through secure means.
- No rough edges - Comma has a cozy theming and is simple to use
- Early warnings - Comma calculates when your next period is expected to arrive, and notifies you beforehand so that you can be prepared
- Cozy design - our icon packs add a more personalized feeling

What are some key Comma features

- Symptom prediction: We have a system which analyzes your past cycles and predicts what you are likely to experience in the days leading up to, and throughout your period
- Early warning notifications: we have notifications to give you early warning on when we predict your next period will start so that you aren’t caught unaware
- Custom symptoms: track things that matter to you that may not traditionally be covered
- Cute icon packs: Have a more comfortable experience with a lighter feeling logger
- Data exports: Share your cycle information quickly with your healthcare provider, or analyze it yourself

What makes Comma the best period app for you?

- If you want to keep your information super private, this is the app for you
- If you want something with a more human than clinical feeling, then we've got you covered
- If you want something built by a small trustworthy team rather than a big corporation, then get downloading!
