ATOMIC NOTES
Notes that stay on your device
A privacy-first notes app. No ads, no trackers, no reading your notes. Optional encrypted cloud sync, powered by a renewable energy allowance.
PHASE 5 · ENERGY + NOTIFICATIONS
Atomic Energy, Coins, and the Notification Center are live.
Opt-in end-to-end encryption, in-app OTP email, the Atomic Energy economy, and an in-app Notification Center have shipped. Payments (coin purchases) and this community platform are next.
LOCAL-FIRST
Your device, first
Notes save instantly and work fully offline. The cloud is optional and under your control.
END-TO-END
Encrypted with a phrase
Turn on a vault and your notes are sealed with a 6-word recovery phrase only you hold.
NO TRACKING
No ads, no analytics
Zero trackers, ad SDKs, or telemetry. The business never reads your notes.
ATOMIC ENERGY
Sync, your way
A renewable energy allowance powers cloud sync. Local note-taking is always free.
