How NBubble handles your information — in plain language.
NBubble is an Android utility that displays a floating chat bubble on your screen, allowing you to access recent notifications at a glance. It can show notification summaries, upcoming events, music controls, and other app-specific information in customizable floating bubbles. This Privacy Policy explains what the app does and does not do with information on your device.
NBubble processes the following information locally on your device only. None of it is transmitted to external servers.
To display notifications in the floating bubble, NBubble uses Android's Notification Listener service. When you grant notification access, the app reads the title, text, and metadata of incoming notifications to display them in the bubble. This content is processed locally and never sent off your device. You grant this permission explicitly in Settings → Notification access.
The app queries your device for installed applications to allow you to customize which apps' notifications appear in the bubble. This information is used locally for filtering and preference management only.
Recent notifications (up to 50 items) may be stored locally in the app for quick access. This history remains on your device and can be cleared by you at any time.
Your settings — such as bubble size, theme, position, blocked apps, and notification filters — are stored locally on your device.
NBubble does not access your messages, contacts, location, photos, microphone, camera, or call logs.

NBubble does not request internet access. It holds no INTERNET permission, so no data of any kind can leave your device. All notification processing happens locally.
Information accessed by the app is used solely to provide its core function: displaying a floating bubble with notification summaries, allowing customization, and maintaining user preferences. We do not use your information for advertising, analytics profiling, or any purpose unrelated to the features you see in the app.
We do not share, sell, rent, or disclose your information to anyone. Notification content and app data never leave your device. No cloud storageNo analytics trackingNo third-party services
All data remains on your device under your control. You can:
All processing happens on-device. Notification data is kept in Android's private per-app storage, which other apps cannot access. Since nothing is uploaded or transmitted, there is no server-side database that could be breached. You remain in control through Android's permission system at all times.
NBubble is a utility app and is not directed to children under 13. It does not knowingly collect personal information from children. Since the app collects no personal data and has no online component, it poses no data-collection risk to users of any age.
NBubble does not integrate advertising networks, analytics tracking, social login, or third-party trackers. It operates as a standalone utility on your device.
Depending on where you live, you may have rights under privacy laws such as the GDPR or CCPA. Since NBubble does not collect personal data on external servers, there is nothing for us to access, correct, export, or delete on your behalf — full control rests with you on your device.
We may update this Privacy Policy if the app's features change. When we do, we will revise the "Effective" date above and publish the updated policy at this address. Continued use of the app after changes take effect constitutes acceptance of the revised policy.
