Privacy
Droid Sentence Miner is designed to work on the device. There is no account, no analytics SDK and no advertising.
On the phone
Section titled “On the phone”- Screen frames are read in memory by the OCR engine. They are not uploaded.
- Recognized lines, screenshots and clip timestamps are stored in a local Room database.
- Dictionaries are imported into a local database.
- Settings live in Android DataStore.
- Anki cards are sent only to the backend you configure: AnkiDroid on the same phone, or your own AnkiConnect server on the local network.
Clearing the app’s data removes all of the above. Settings → Dictionaries → Delete removes one dictionary. The text log has its own controls.
Network requests
Section titled “Network requests”The app makes a network request only for a feature you use:
| Request | When |
|---|---|
| GitHub Releases | One-tap dictionary installs (Jitendex, JMdict, Kanjium accents, Pixiv Light); the app update check when the app opens (turn it off in Settings → About) and the APK download when you tap Update. |
| Google Drive | When you open a shared Drive link on Settings → Dictionaries (folder listing and download). Files picked with Browse my Drive are read by the Google Drive app. |
| Hugging Face | One-time meikiocr model download (31 MB). |
| Your AnkiConnect URL | When mining with the AnkiConnect backend. |
| JapanesePod101, Jisho | Word audio lookup when Word audio is enabled. |
| Your custom audio URL | If you configure one. |
Google ML Kit runs on-device. Model updates, if any, are managed by Google Play services under Google’s terms, not by Droid Sentence Miner.
Permissions
Section titled “Permissions”- Screen capture — Android MediaProjection consent, granted per session. The app sees only what you choose to share.
- Microphone — needed for playback capture on Android and for the optional microphone fallback. Audio is processed locally.
- Notifications — keeps the foreground capture service visible.
- Display over other apps — draws the bubble, live text window and screen dictionary.
- AnkiDroid API — creates notes and media through AnkiDroid’s provider.
Diagnostics
Section titled “Diagnostics”Release builds have no remote logging. Debug builds expose a localhost-only HTTP API on port 9099 for development; it is not present in release APKs. Logcat output stays on the device unless you capture it yourself.
Third-party services
Section titled “Third-party services”Links to GitHub, Anki, Yomitan, Jitendex, Hugging Face and the audio sources open in your browser or are contacted by the app only as listed above. Their privacy policies apply to those requests.
License
Section titled “License”The app is GPL-3.0. The source is public, so these claims can be checked rather than trusted.
