Privacy Policy
This policy explains what data the Subtitle Converter Android app ("the app") and this website use, and why. In short: your videos and audio are processed on your phone and are never uploaded to us. The app shows ads, and the ad provider collects some device data as described below.
Your videos, audio and subtitles
- Speech recognition and translation run on your device. Your media files, the text recognised from them, and the subtitles you make are not sent to us or stored on our servers.
- Files you create are saved only where you choose on your phone. You can delete them at any time.
- The app reads only the files you pick or share to it.
Language files the app downloads
The first time you use a language, the app downloads the AI model or translation files it needs. Translation files are provided by Google ML Kit. These downloads send your device's IP address and basic request details to the server that hosts the files, as with any download. They do not include your media.
Ads
The app is free because it shows ads through Google AdMob. To show and measure ads, and to prevent fraud, Google may collect:
- your device's advertising ID,
- your IP address and approximate location derived from it,
- device and app information such as model, operating system and app version,
- how you interact with ads.
If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent before personalised ads are shown, using Google's consent tool. You can change your choice at any time from the app's settings. On any Android phone you can reset or delete your advertising ID in your device settings under Google › Ads.
Learn more in how Google uses information from apps that use its services.
Crash reports and usage statistics
To fix bugs, the app may send anonymous crash reports and basic usage counts (for example, which features are used). These contain no media, no subtitles and no personal contact details.
Permissions the app asks for
- Media and files: to open the video or audio you choose and save the results.
- Notifications: to show progress while long files are processed in the background.
- Internet: to download language files and show ads. Making subtitles works offline.
This website
This website does not use cookies or analytics trackers. It loads fonts from Google Fonts, which receives your IP address when the page loads. Our hosting provider keeps standard server logs for security.
The online subtitle generator
- Your video or audio file is processed inside your browser. It is not uploaded to us or anyone else.
- The first time you use it, your browser downloads the speech recognition software from jsDelivr and the AI model from Hugging Face, and stores them on your device. Like any download, these services receive your IP address. They do not receive your file.
- If you choose a subtitle language other than the spoken language or English, the translation is done by the translator built into your browser (for example Chrome), under that browser's privacy policy.
- The subtitles you make stay in your browser until you download them. Closing the page deletes them.
Children
The app is not directed at children under 13, and we do not knowingly collect personal data from them.
Data sharing and sale
We do not sell your personal data. Data is shared only with the service providers named above, for the purposes described.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data, or to object to its use. Because we do not store your media or an account for you, most data related to the app is held by Google for ads. Contact us and we will help with any request.
Changes
If this policy changes, we will update the date at the top of this page and, for important changes, tell you in the app.
