PRIVATE, SMART & SECURE
Privacy-First: Your journey is private. No mandatory accounts, no cloud tracking. Your data and your progress stay on your device, exactly where they belong.

Ownership of Data: You worked hard for your vocabulary. Export and import your custom "My Words" lists. Share them with loved ones, or move them to another device.

ACCESSIBILITY SERVICE API DISCLOSURE
To provide the core functionality of D’Blocker and Practice at Block, this app requires the use of the AccessibilityService API:

How it works: We use this API to detect when a user-selected "monitored app" (such as social media) is launched or scrolled.

Why it is used: This is necessary to trigger educational overlays and enforce your chosen focus boundaries, helping you transition from mindless scrolling to active learning.

Data Privacy: We value your privacy. D’Cards & Focus Engine does not collect, store, or transmit any personal data, keystrokes, messages, or browsing history through the AccessibilityService API. All monitoring is processed 100% locally on your device. ## Rankings - #3,073,413 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK` - `android.permission.FOREGROUND_SERVICE_SPECIAL_USE` - `android.permission.INTERNET` - `android.permission.PACKAGE_USAGE_STATS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.cabcode.doomblockerfocus.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [FocusNPlay - Study to Scroll](https://chrome-stats.com/d/com.focusnplay.phasetimer) — 739 users - [CardGate: Learn then Scroll](https://chrome-stats.com/d/com.cardgate) — 268 users - [FluentMode: Earn Your Scroll.](https://chrome-stats.com/d/com.fluentmodeapp) — 23 users - [DeepL: Focus & App Blocker](https://chrome-stats.com/d/com.brilliantcorp.focushabit) — 2,214 users - [Focards](https://chrome-stats.com/d/com.studybattle.studybattle_app) — 34 users - [Lucid: App Blocker & Focus](https://chrome-stats.com/d/app.lucidfocus) — 25 users - [Study Timer for Focus - Regain](https://chrome-stats.com/d/im.ai.regainapp.regainfocus.focus) — 105 users - [Nemia: Study Lock Flashcards](https://chrome-stats.com/d/app.nemia.android) — 94 users - [Decklio](https://chrome-stats.com/d/de.lits.decklio) — 3 users - [Languager: Learn Language Fast](https://chrome-stats.com/d/uk.co.highapp.audiobook.ebooks) — 11,903,845 users, 4.56 / 5 - [LingoLock](https://chrome-stats.com/d/com.lingolock.app) — 18 users - [Detour – Focus Challenges](https://chrome-stats.com/d/com.xaesion.detour) — 16 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.cabcode.doomblockerfocus)
