The Problem

80% of app privacy
labels are false.
We never built
the pipes.

“We don't collect data because we never built servers to receive it. The app cannot transmit your data even if we wanted it to — it has no network permissions.”

How It Works

Privacy by architecture,
not by promise.

Traditional App
Your Data App Their Servers Third Parties
Hackable Subpoenable Sellable
vs
OnlyOffline
Your Data Your Device × Nowhere
AES-256 Encrypted Your Control Only
01

Zero Network Permissions

The app declares no network permissions in its manifest. It physically cannot connect to the internet.

02

AES-256 Encryption

All data encrypted on-device with keys stored in your device's secure enclave. Only you can access it.

03

No Servers Exist

We never built infrastructure to receive your data. There's nothing to hack, subpoena, or sell.

04

Open Source Core

Privacy-critical components are open-sourced on GitHub for anyone to audit and verify.

Safety Features

Built for people who need
real protection.

In a world where personal data can be weaponized, we built features that go beyond privacy into active safety.

Critical Safety

Decoy Mode

A secondary PIN opens a fake version of the app with empty or realistic-looking decoy data. No visual indicator reveals which mode is active. In jurisdictions where personal data could be used against you, plausible deniability matters.

Real data
Decoy data

Quick Purge

Emergency data deletion with configurable triggers. Shake pattern, specific PIN, widget button. Immediate, irrecoverable. Speed is safety.

Anonymous Icon

Disguise the app as a calculator, notes app, or generic utility. No one looking at your phone will know it's a private app.

Open Export

Your data in JSON, CSV, FHIR R4, or PDF. Standard formats you can take anywhere. No lock-in, ever.

Privacy Policy

We don’t collect data.
There’s nothing to collect.

OnlyOffline apps have no servers, no analytics, no crash reporting, no telemetry, and no network permissions. Your data lives on your device and nowhere else. This is the entirety of our privacy policy because there is nothing else to say.
