Privacy Policy

Last updated: March 2026

Core Principles

ZenNotify was built on the principle of extreme privacy. We believe that your focus is your most valuable asset, and that managing it shouldn't come at the cost of your personal data.

Data We Access & Collect

To provide its core functionality, ZenNotify accesses and processes the following data entirely on your device. None of this data is transmitted, uploaded, or shared with any server, third party, or external service.

Data Type	What We Access	Why We Need It
Notification Content	App name, notification title, text, and category of incoming notifications	To evaluate your rules and decide whether to filter, batch, mute, or allow each notification
Location Data	GPS coordinates (foreground and background)	Used ONLY for geofencing filters — to activate or deactivate rules when you enter or leave a specific area. We do not store a history of your location.
Activity Recognition (Health Data)	Physical activity state (e.g., walking, driving, biking, still)	Used to detect when you are driving or biking for automated safety silencers. This data is classified as Health Data by Google. It is processed entirely on-device using Android's Activity Recognition API and is never stored or transmitted.
Usage Statistics	Currently active/foreground app package name	Used to identify which app is currently in use so smart filters can be applied contextually
Bluetooth Device Names	Names of paired/connected Bluetooth devices	Used for proximity-based rules (e.g., silence notifications when connected to car Bluetooth)
WiFi Network Names	SSID of currently connected WiFi network	Used for location-based rules that trigger based on specific WiFi network connections

Health Data Disclosure

ZenNotify accesses Activity Recognition data, which Google classifies as Health Data. Specifically, the app uses Android's Activity Recognition API to detect your current physical activity (driving, biking, walking, or still). This data is:

• Processed entirely on your device — never transmitted to any server
• Used only to automatically activate safety silencer rules when you are driving or biking
• Never stored — the activity state is evaluated in real-time and immediately discarded after the rule check
• Never shared with any third party, analytics service, or advertising network

Permissions & Usage

To provide its core functionality, ZenNotify requires specific permissions. Here is exactly why we use them:

• Notification Access: Essential for intercepting and filtering incoming alerts according to your rules. This permission is managed strictly by the Android system and is never processed off-device.
• Location Access: Used ONLY for Geofencing and WiFi-based filters. This allows the app to activate rules when you enter or leave a specific area. We do not store a history of your location.
• Background Location: Allows location-based and WiFi-based rules to continue working when the screen is off or the app is in the background.
• Foreground Service: Required to keep the protection system running consistently in the background to guard your focus.
• Activity Recognition: Used to detect when you are driving or biking for automated safety silencers. This is classified as Health Data and is processed entirely on-device.
• Usage Stats: Used to identify the currently active app for context-aware smart filters.
• Bluetooth: Used to detect connected Bluetooth devices for proximity-based rules.
• WiFi / Nearby Devices: Used to detect connected WiFi networks for network-based rules.
• Post Notifications: Required to show batched notification summaries and status alerts.
• Camera: Used only for the flashlight feature in rule actions.

Data Security

Any settings or rule metadata stored by the app is kept in an encrypted local database. Since there is no internet access, there is no remote server that can be breached to access your information.

Data Retention & Deletion

ZenNotify stores all data exclusively on your device. Here is how long data is retained and how you can delete it:

Data	Retention Period	How to Delete
Notification history (Vault)	User-configurable: 3, 7, 14, or 30 days, or until manually cleared. Default is forever (until cleared).	Go to Settings → Vault Auto-Cleanup to set automatic deletion, or use Settings → Delete My Data to clear everything immediately.
Rules & Settings	Stored until user deletes them or clears app data	Delete individual rules from the Rules screen, or use Settings → Delete My Data to clear everything.
Activity Recognition data	Not stored — evaluated in real-time only	No deletion needed; data is never persisted.
Location data	Not stored — used for real-time geofencing only	No deletion needed; data is never persisted.
Dashboard statistics	Stored until user clears app data	Use Settings → Delete My Data to clear everything.

How to Delete Your Data

You can delete all your data at any time using one of these methods:

• In-App: Open the app → go to Settings → tap "Delete My Data". This will permanently erase all notification history, rules, settings, and preferences from your device.
• Android System: Go to your device's Settings → Apps → ZenNotify → Storage → Clear Data. This removes all app data from your device.
• Uninstall: Uninstalling ZenNotify automatically removes all stored data from your device.

Since ZenNotify is 100% offline and stores no data on any server, deleting the app or clearing app data guarantees complete and permanent removal of all your information.

Third-Party Services

There are no third-party SDKs, tracking pixels, or advertisement networks integrated into ZenNotify. The app is 100% ad-free. The only third-party integration is Google Play Billing, which is used solely for processing premium subscription purchases through the Google Play Store.

Children's Privacy

ZenNotify does not knowingly collect any personal information from children under 13. The app does not target children and does not collect age-related information.

Changes to this Policy

We may update this policy from time to time as we add new features. However, our commitment to keeping ZenNotify offline and private will never change. We will update the "Last updated" date at the top of this page when changes are made.
