Ryan here (co-founder of YC-backed Muzz). I’m now building Onin, an end-to-end encrypted calendar and chat app that makes organising your personal and social life simple and secure.
I’ve been building technology businesses for 10+ years and have witnessed the reoccurring problem that digital calendars were built for companies, not people. They feel cold, transactional, and anti-social — not the thing of dreams for planning your personal life. They also lack the security we now come to expect from consumer products.
Onin is the first calendar to be fully E2EE, protecting not just your events, but your messages and even your profile. Unlike existing E2EE calendars, you cannot share Onin events to others without the protection of E2EE. When you consider how much personal information your calendar stores about you and your loved ones’ lives, we think this is essential.
With such a focus on security and privacy, it’s only fitting that we host our Privacy Policy and Terms of Service on GitHub to be as transparent as possible with our users.
But beyond security, how is Onin so different?
Our research found that 84% of events are planned entirely in chats. But our calendars are disconnected from these conversations, leaving our schedules constantly out of sync.
To fix this, we’ve collapsed and combined calendar and chat into one secure app, eliminating the fragmentation between events and the conversations that form them.
Some of our unique features include:
- Calendar keyboard: Access your calendar from within the chat
- Event chats: Creating a new event generates a dedicated chat
- Just phone numbers: No more searching for your friend’s email
- End-to-end encryption: All our events and chats are E2EE, even your profile too
Onin is proudly the world’s most private calendar by default:
- End-to-end encrypted events, profiles, and messages
- Two-Factor Authentication required
- Chat without revealing your phone number
- (Coming soon) Your unique link to invite people, no need to share your number
We’re exactly 4 weeks away from launching the public beta to our waitlist community. You can check out all the features we have coming here and join too at the link above.
I’d love to hear your feedback and answer any questions!
