Privacy Policy - Silence Cutter

Last Updated: 26 April 2026
Effective: 26 April 2026

This Privacy Policy describes how Silence Cutter (the "App"), published by BinaryScript ("we", "us", "our"), handles information when you use the App.

The short version: Silence Cutter does not collect personal data. All video processing — silence detection, transcription, and export — happens entirely on your device. Subscriptions are processed through Google Play Billing; we never see your payment details.

1. Who We Are

Silence Cutter is published by BinaryScript.

Email: [email protected]

2. Information We Collect

We do not collect any personal information.

We do not gather:

  • Your name, email address, phone number, or any account details
  • Your device's IMEI, advertising ID, MAC address, or other identifiers
  • Your location, IP address, or network information
  • Your contacts, calendar, photos (other than what you explicitly pick), SMS, call logs, or any other personal content
  • Cookies, tracking pixels, or any web-style tracking technology

We do not have a backend server. We do not run analytics services. We do not embed third-party SDKs that phone home. We do not have a marketing pipeline.

3. What the App Accesses on Your Device (and Why)

The App requests only the permissions strictly needed to run, listed below with the corresponding purpose.

READ_MEDIA_VIDEO (Android 13+) / READ_EXTERNAL_STORAGE (Android 12 and below, max API 32)

Granted automatically when you pick a video through the system Photo Picker. Used solely to read the file you explicitly select.

POST_NOTIFICATIONS (Android 13+)

Used to display the export-progress notification while the video is being processed in the background. Without it, exports still run, but you will not see the progress notification.

FOREGROUND_SERVICE / FOREGROUND_SERVICE_MEDIA_PROCESSING

Required by Android to keep a long-running export alive when the App is not in the foreground. The service stops as soon as the export finishes.

WAKE_LOCK

Prevents the device from sleeping mid-export so the encoding pipeline completes. Released the moment the export finishes.

BILLING

Used by Google Play Billing to process subscription purchases. Payment information is handled entirely by Google Play; we never see or store your credit card, UPI, or other payment details.

The App does not request: CAMERA, RECORD_AUDIO, READ_CONTACTS, ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION, SEND_SMS, READ_PHONE_STATE, GET_ACCOUNTS, BLUETOOTH, NFC, or any other sensitive permission.

4. What the App Does With Your Files

When you pick a video, the App reads it from your device's storage to analyze the audio track and identify silent regions and (optionally) speech segments. The App then writes a new video file containing the edited result to:

/storage/emulated/0/Android/data/com.binaryscript.silencecutter/files/Movies/SilenceCutter/

and, on Android 10 (API 29) and later, also publishes the file into the device's gallery via MediaStore at:

/storage/emulated/0/Movies/SilenceCutter/

The App also writes:

  • A .srt subtitle sidecar file alongside the exported video, when you have transcribed the source.
  • A small JSON project-state file under /data/data/com.binaryscript.silencecutter/files/projects/ which remembers your silence toggles per source video so you can resume editing later. This file never leaves your device.
  • Settings preferences via Android's DataStore.

You can delete any of these files at any time using a file-manager app.

5. On-Device Transcription (Optional)

If you choose to install a Whisper GGML model file via Settings, the App copies that file into its own private storage and runs speech-recognition inference locally using whisper.cpp.

The model file, the audio it processes, and the resulting transcript all remain on your device. They are never uploaded.

You may remove the model at any time from Settings → Transcription model → Remove.

6. Subscriptions and Google Play Billing

Silence Cutter offers paid subscription tiers processed through Google Play Billing. When you subscribe:

  • Google Play handles the entire payment flow. We never see, store, or transmit your credit card, UPI, or other payment details.
  • The App receives only a subscription status token from Google Play that tells it whether your subscription is active.
  • Subscription records held by Google Play are retained by Google according to Google's policies.

7. Children's Privacy

The App is rated for general audiences. We do not knowingly process the personal data of any minor, because we do not process anyone's personal data — full stop.

8. Third-Party Services

The App is not integrated with any third-party analytics, advertising, crash-reporting, or marketing service.

The App uses these open-source libraries that run entirely on-device:

  • AndroidX (Compose, Media3 ExoPlayer, Media3 Transformer, DataStore)
  • Kotlin standard library and coroutines
  • whisper.cpp (MIT license, used for optional on-device transcription)
  • ggml (MIT license, the tensor library whisper.cpp depends on)

The only network behavior in the App is the Google Play Billing communication required to verify your subscription status.

9. Security

Because we do not collect, transmit, or store user data anywhere outside of your own device, there is no remote data store to breach. Your videos and edits are protected by the standard sandboxing of the Android operating system. Communication with Google Play Billing is secured via TLS.

10. Changes to This Policy

If we ever update this policy, we will:

  • Bump the "Last updated" date at the top
  • Bump the App's version number in the corresponding release
  • Highlight the change in the Play Store "What's new" section

Material changes (anything that would alter our no-collection stance) would require an explicit App update; you would have to install the new version for any change to take effect.

11. Your Rights Under Privacy Law

GDPR (EU), CCPA (California), DPDP Act (India), and similar laws give you rights over your personal data. Since we do not collect any of your personal data, those rights are automatically satisfied:

  • Right to access — there is nothing to access
  • Right to deletion — there is nothing to delete
  • Right to data portability — there is nothing to port
  • Right to opt out of sale — we do not sell anything

You may also delete the App at any time, which removes all of its on-device data along with it.
