About Offgrid

A private writing space built to feel calm, discreet, and personal. No servers, no accounts — everything lives on your device.
The AI never reads your diary unless you explicitly ask it to. Your data stays local.

Location

Your location
Not set — used only for personalised greetings

Community

Let us know you exist Sends one anonymous count — no ID, no device info, no diary content. Just +1 to a global counter so we know the app is used. Optional, reversible at any time.

UX Analytics (local only)

Anonymous button-usage counts stored on this device. Never sent anywhere. Helps us understand what features matter most.

A 30-day survival writing game
The Regime is watching.

Every day, The Regime selects a set of forbidden words. You don't know what they are. You must write your daily entry without triggering them.

You must also stay in character — this is a surveillance state. Write as a citizen under watch. If The Regime's analysis detects non-compliance, or if you use a forbidden word, it's GAME OVER.

Survive all 30 days without detection to earn your freedom.
