Daymoz & Deimos

Deimos is the outer moon of Mars — small, quiet, always in orbit. It never drifts away. That's the idea behind DayMoz: the people in your life, always close, always on your orbit.

🌑
Deimos
Moon of Mars. Orbital period: 30 hours. Never leaves its orbit.
DayMoz
DayMoz
Your contacts, groups and notes. Always in orbit around you.

You decide who sees what

Notes are encrypted before they leave your device. The server stores only the encrypted result. A database breach exposes nothing readable.

Privacy →
Private: only you
Encrypted on your device with a key derived from your account. Sign in on any phone and access restores automatically. Nobody else can read it.
Group: members only
Encrypted with a group key that every member computes locally. No key is transmitted. Nobody outside the group can read it.
Local storage encrypted
All local data is encrypted with a random key stored in the device keystore: Android Keystore or iOS Keychain.
HTTPS + Certificate Pinning
All traffic is TLS-encrypted. The app pins the server certificate and rejects MITM attempts, including corporate proxies.
