Just an Offline Toolbox Privacy
Just an Offline Toolbox 1.0 runs its core features on your device. It does not require an account and includes no ads or analytics SDKs.
On-device processing
Text you enter and images or PDFs you select are processed on the current device by default. The app does not upload tool content to our servers.
Ash messages
On iOS, one-time private keys are stored in the device-only Keychain. An opened message is shown for 30 seconds, hidden immediately in the background, and removed from app state when the timer ends or you leave. The first Android release can send Ash messages but does not store receiving keys.
A recipient can still copy, screenshot, or photograph content before the timer ends. Burn-after-reading cannot prevent deliberate retention.
Permissions and network access
- Camera or photo access is requested only when you choose or capture a QR code or image.
- Opening this website, privacy notice, or support page leaves the app and requires an internet connection.
- Destinations selected in the system share sheet process shared files under their own policies.
