Privacy Policy
Linux Commands is an offline reference guide for Linux commands, published by Vivek Kumar. This policy explains what the app collects, why, and what control you have over it.
The short version
The app has no accounts and no sign-in, and never asks for your name, email address, phone number, contacts, photos, location, or files. The entire command library is bundled in the app and works offline. What is collected is limited to anonymous usage and stability data, plus advertising identifiers used to serve ads.
What the app collects
The app itself stores two things on your device only, and never transmits them:
- Which commands you mark as favourites
- Your theme preference and whether you dismissed the in-app tip
These are removed when you uninstall the app.
Third-party services
The app uses the following Google services, which collect data on their own terms:
- Google Analytics for Firebase — anonymous usage events (for example, opening a screen, copying or sharing a command, running a search), together with device model, operating system version, app version and approximate region derived from IP address.
- Firebase Crashlytics — crash and error reports, including stack traces and device state at the time of the crash, used to diagnose and fix defects.
- Google AdMob — serves the advertising in the app. AdMob may access your device's advertising identifier and information about ad interactions in order to deliver and measure ads, including personalised ads where you have permitted them.
These services act as data processors for the app and also process data under Google's own policies. See Google's Privacy Policy and Firebase's privacy documentation.
Advertising identifiers
Ads are supported by your device's advertising ID, a resettable identifier that is not tied to your name or account. You can reset it, or opt out of personalised advertising entirely, in your Android settings under Settings → Privacy → Ads. Opting out does not remove ads; it makes them less relevant.
What is never collected
- No personal or contact information
- No precise location
- No access to your files, photos, camera, microphone or contacts
- No commands you view or copy are transmitted anywhere
Sharing and sale of data
Data is not sold, and is not shared with anyone beyond the Google services listed above, which process it to provide analytics, crash reporting and advertising. Information may be disclosed if required by law.
Retention
Analytics and crash data are retained according to Google's default retention periods for Firebase, which are configured in the Firebase console. Data stored on your device persists until you clear the app's data or uninstall it.
Children
The app is a technical reference intended for a general audience and is not directed at children under 13. It does not knowingly collect data from children.
Your choices
- Reset or delete your advertising ID, or opt out of ad personalisation, in Android settings
- Clear the app's stored data from Settings → Apps → Linux Commands → Storage
- Uninstall the app, which removes everything stored on your device
Changes to this policy
This policy may be updated as the app changes. The effective date at the top of this page reflects the most recent revision.
