FocusGuard — Privacy Policy

Effective date: 2026-05-28 · Developer: CoreSpark Apps

Short version: All data stays on your device. We collect nothing, upload nothing, sell nothing. No account required.

1. Data We Access

1.1 App Usage Statistics

FocusGuard uses Android's UsageStats API (PACKAGE_USAGE_STATS permission) to read how long each app has been used in the foreground.

Purpose: Display per-app screen time, enforce daily limits, compute your Focus Score.
Storage: Stored locally in an on-device database. Never transmitted to any server.
Retention: Kept on your device until you uninstall the app or clear app data.

1.2 Foreground App Detection (Accessibility Service)

FocusGuard uses Android's AccessibilityService to detect which app is currently in the foreground.

Purpose: Detect when a blocked or limited app is opened so the Mindful Intercept or Focus Session screen can be shown.
What is read: Only the foreground application's package name (e.g. com.instagram.android). No text content, no keystrokes, no passwords, no screen content of any kind.
Storage: Package names are used transiently to trigger the intercept overlay and immediately discarded — not stored.

1.3 Installed App List

FocusGuard queries installed applications (QUERY_ALL_PACKAGES) to populate the app-limit picker and resolve app icons and names.

Purpose: Let you choose which apps to limit.
Storage: Not stored persistently. Queried fresh each time the app list is displayed.

1.4 User-Created Data

The following data is created by you inside the app and stored locally on your device only:

Data	Purpose
App limits (app, daily limit)	Enforce limits
Focus sessions (start time, duration, completion)	Focus Score, session history
Streaks (consecutive days within a limit)	Focus Score, motivation
Preferences (bedtime window, onboarding state)	App configuration

2. Data We Do NOT Collect

FocusGuard does not:

Create or require user accounts
Transmit any data to our servers (we have no servers)
Share data with third parties, advertisers, or data brokers
Use any analytics SDK
Track your location
Access your contacts, microphone, camera, or files
Read the content of any app you use

3. Crash Reporting (Optional)

A future version of FocusGuard may include Firebase Crashlytics for crash reporting. If and when this is added, crash reports will contain only device model, Android version, app version, and a stack trace — no usage data, no limits, no personally identifiable information. You will be notified in the app and can opt out. Until then, no crash data is sent.

5. Children's Privacy

FocusGuard is not directed at children under 13. We do not knowingly collect any personal information from children.

6. Data Security

All data is stored on your device and protected by Android's application sandbox and your device's lock screen. FocusGuard does not implement additional encryption beyond what Android provides by default. We recommend using a strong device lock screen.

7. Your Rights

Since we hold no data about you on our servers, there is nothing for us to delete or export on our end. You can:

Delete all app data: Android Settings → Apps → FocusGuard → Storage → Clear Data
Uninstall the app to remove all locally stored data permanently

8. Changes to This Policy

We may update this policy from time to time. The effective date at the top reflects the latest revision. Continued use after an update constitutes acceptance. We will notify you of material changes via an in-app notice.
