App settings
Open Settings with the gear icon in the top-right corner of any screen.
Appearance
Choose how the app looks:
| Option | Effect |
|---|---|
| System | Follows the phone's light/dark setting. This is the default. |
| Light | Always light. |
| Dark | Always dark. |
Language
| Option | Effect |
|---|---|
| System default | Follows the phone's language. This is the default. |
| English | Always English. |
| Čeština | Always Czech. |
The change applies immediately — you do not need to restart the app.
Security
Lock app with Face ID / passcode — Require authentication on launch and when returning to the app. Off by default.
When it is on, the app asks for your biometrics or device passcode each time you open it and each time you switch back to it from another app. Switching it on does not lock the app straight away; it takes effect the next time you launch or return to the app.
If the phone has no screen lock of its own, the app opens normally rather than locking you out.
STICKER change log
How long to keep the config-change history for each saved STICKER. Off stops logging (existing logs are kept).
| Option | Effect |
|---|---|
| Off | Stop recording. Logs already recorded are kept. |
| 30 days | The default. |
| 60 days | |
| 90 days |
The change log records every configuration read and every successful write for a saved device. See Device change log for how to read, export and reapply entries.
Debug mode
Tapping the HARDWARIO logo at the bottom of the Settings screen five times turns Debug mode on or off. A counter appears after the first tap to show how many taps are left.
Debug mode adds the NFC Console to the STICKER Tools menu — a low-level
console for raw NFC commands — and shows a thin debug mode strip under the
header so you always know it is on. It is a diagnostic aid; leave it off for
normal use.
Debug mode is remembered, so it stays on until you turn it off again.
