I built ourRegla because every period app we tried wanted the same thing: an account that keeps your cycle history on their servers. For data that personal, that felt backwards.

So the cycle data stays on the phone. The cloud only helps two phones find each other; what partners share is encrypted on the device (X25519 + AES-GCM), and the relay only ever sees ciphertext.

The partner side is the part I'm proudest of. You invite your partner with a one-time code — no shared passwords, no seeing each other's whole app. They get a heads-up before the period starts (so "why are you so moody?" becomes "want me to bring chocolate?"), and you can both send stickers.

And then there are the invitation cards: a cartoon couple, a hand-written note — "Movie night in!!?", "Want to grab a coffee!!?" — and everyone knows it isn't really about the coffee. Some things are easier to send than to say. 🔥🧯

Solo project. What would you want your partner to see — and what should never leave your phone?
