Privacy Policy
Effective Date: February 8, 2026
Open Zero Launcher ("we", "us", "our", or "the App") is an open-source, free, and ad-free Android launcher application developed by PrimeDeploy. This Privacy Policy explains how we collect, use, and protect information when you use our App. We are committed to protecting your privacy and being transparent about our data practices.
Information We Collect
1. Location Data
The App requests access to your device's location (coarse and fine location) solely to display local weather information on your home screen. Location coordinates (latitude and longitude) are sent to the Open-Meteo API to retrieve current weather data. Your location data is:
- Not stored on any external server.
- Not shared with any third party other than Open-Meteo for weather retrieval.
- Used only in real-time to fetch weather data and is not persisted beyond the current session.
You may deny location permission at any time; the App will continue to function normally without weather information.
2. Locally Stored Data
The App stores the following data locally on your device only using SQLite and AsyncStorage:
- App usage statistics — how often and when you open installed apps, used to display your most-used apps.
- Favorite apps — the apps you select as favorites and their order.
- Hidden apps — apps you choose to hide from the app list.
- App lock configuration — whether app locking is enabled and a SHA-256 hash of your password (your plaintext password is never stored).
- Locked apps — apps you have chosen to lock.
- First launch status — whether the initial setup has been completed.
All of this data remains entirely on your device. We do not have access to it, and it is never transmitted to any server.
3. Installed App Information
The App reads your list of installed applications to display them in the launcher interface, provide app shortcuts, and enable launching, uninstalling, or viewing app info. This data is:
- Not transmitted to any external server.
- Not shared with any third party.
- Processed entirely on-device.
4. Notification Access
If you grant notification access permission, the App reads notification counts from other apps to display notification badges on the home screen. The App:
- Does not read the content of your notifications.
- Only counts the number of active notifications per app.
- Does not store or transmit notification data externally.
You may revoke notification access at any time through your device settings.
Information We Do NOT Collect
- We do not collect personal information such as your name, email address, phone number, or account details.
- We do not use analytics, tracking, or advertising SDKs.
- We do not collect device identifiers, advertising IDs, or fingerprinting data.
- We do not use cookies or similar tracking technologies.
- We do not sell, rent, or share any user data with third parties.
- We do not have user accounts or registration.
Third-Party Services
The App uses the following third-party service:
| Service | Purpose | Data Sent | Privacy Policy |
|---|---|---|---|
| Open-Meteo | Weather data | Latitude & longitude coordinates | Open-Meteo Privacy Policy |
Open-Meteo is a free, open-source weather API that does not require API keys and does not track users.
Data Security
- All user data is stored locally on your device using SQLite and AsyncStorage.
- Passwords for the app lock feature are hashed using SHA-256 with a salt before storage; plaintext passwords are never stored.
- No data is transmitted to our servers because we do not operate any servers.
- The App's source code is publicly available on GitHub for full transparency and independent review.
Children's Privacy
The App does not knowingly collect any personal information from children under the age of 13. Since the App does not collect personal data from any user, it is inherently compliant with children's privacy regulations.
Permissions Explained
| Permission | Purpose |
|---|---|
INTERNET | Required to fetch weather data from Open-Meteo API |
QUERY_ALL_PACKAGES | Required to list installed apps for the launcher interface |
ACCESS_COARSE_LOCATION | Used to determine approximate location for weather data |
ACCESS_FINE_LOCATION | Used to determine precise location for weather data |
RECEIVE_BOOT_COMPLETED | Allows the launcher to be available after device restart |
VIBRATE | Provides haptic feedback for user interactions |
POST_NOTIFICATIONS | Allows the App to post notifications if needed |
REQUEST_DELETE_PACKAGES | Enables the app uninstall feature from within the launcher |
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Effective Date" at the top of this document and by publishing the updated policy in the App's repository. We encourage you to review this Privacy Policy periodically.
