Privacy
Last updated 24 September 2026
This policy covers the Colugo family of Android apps, currently Colugo Scan. It explains what stays on your device, what leaves it, and who receives it.
The short version
Colugo apps have no accounts and no sign-in. Scanning is done entirely on your device, and your scan history never leaves it. The one thing that does send data off your device is advertising, which is served by Google AdMob.
Scanning
Colugo Scan reads codes using the camera. The recognition model is bundled inside the app, so decoding happens on your device and works with no network connection.
- Camera frames are used only to detect a code and are not saved.
- Camera images and decoded contents are not uploaded anywhere.
- The app does not take or keep photographs.
What is stored on your device
- History — the text of codes you scan or generate, with a timestamp and type. Stored only in the app's private storage, capped at the most recent entries.
- Settings — your theme, Material You and accent choices.
- Images you save — when you tap Save, the code image is written to your device gallery. Nothing is uploaded.
None of it leaves the device. Delete a single history entry with the bin icon beside it, or remove everything by uninstalling the app.
Wi-Fi codes
A scanned Wi-Fi code contains the network password. Colugo Scan does not display it — it shows the network name and keeps the password available only through the "Copy password" action. The scanned text is held in your on-device history like any other code, and is never transmitted.
Advertising
Colugo Scan shows ads served by Google AdMob. AdMob is operated by Google and collects data for advertising, including:
- your device's advertising ID and other device or app identifiers;
- device information such as model, operating system version and language;
- your IP address, from which an approximate location can be derived;
- interaction with the ads shown, such as views and taps.
This collection is carried out by Google, not by Colugo. Colugo receives aggregate reporting only, and never sees these identifiers. Google's handling of this data is described in Google's Privacy Policy and in how Google uses data from partner sites and apps.
You can reset or delete your advertising ID at any time in Settings → Privacy → Ads on your Android device.
Permissions
- Camera — to read codes. Requested the first time you open the Scan tab; the app works without it apart from scanning.
- Internet — used to load ads.
- Advertising ID — used by AdMob as described above.
Children
Colugo apps are not directed at children, and no data is knowingly collected from them.
Changes
If this policy changes, the date at the top changes with it. Material changes will be described here rather than made quietly.
