About

Withinon is a privacy-first social app: posts that fade on their own, chats sealed end to end on your phone, and Glow, our own camera effects.

This blog is where we write about how it's built: the encryption design, how fading media works, how we keep a social app useful without tracking people, and the mistakes we fix along the way.

We never read your chats and we don't track you outside Withinon. Personalised ads are off unless you switch them on.
