Privacy: AI Sub Video Player

AI Sub Video Player — Privacy Policy

Last updated: 4 November 2026

AI Sub Video Player (“the app”) is made by Invisible Space. This policy says what the app does with your information. The short version: your videos and the subtitles made from them never leave your phone. There are no accounts, and we run no servers of our own, so nothing you do in the app is ever sent to us.

What stays on your phone

• Your videos. The app plays only the folders and videos you choose through Android’s own file picker. It does not ask for access to the rest of your storage.
• Subtitles. Speech recognition and subtitle writing run entirely on your phone. The subtitles are saved in the app’s private storage so they are ready next time.
• Your library and history. The folders you added, where you stopped in each video, your watch history and your settings are kept in the app’s private storage.

Removing a video or a folder from the library never deletes it from your phone. Clearing the app’s data in Android’s settings, or uninstalling the app, deletes everything listed above.

What goes over the internet, and to whom

• Speech models are downloaded from Hugging Face (huggingface.co) when you choose one. As with any download, Hugging Face’s servers see your IP address and a standard web request. Nothing about your videos is sent. See the Hugging Face privacy policy.
• Translation languages other than English use Google ML Kit, which Google Play delivers to your phone together with the first language you download. Translation runs on your phone; the text being translated is not sent anywhere. ML Kit does send Google diagnostic and usage information: your device model and Android version, the app’s name and version, performance measurements and error codes, the languages you translate between, and an identifier for this installation. Google uses it to keep ML Kit working, and says it does not pass this data to third parties. It is sent encrypted.
• Updates and reviews. The app can offer a new version, and occasionally ask for a rating, through Google Play. Those screens are run by the Google Play Store app, under Google’s privacy policy.

Advertising

If the version of the app you are using shows ads, they are served by Google AdMob. To show and measure ads, and to prevent ad fraud, AdMob collects your IP address (which can indicate your general location), how you interact with the app and its ads, app performance information, and your device’s advertising ID and app set ID. This data is sent encrypted to Google, and is handled under how Google uses information from apps that use its services.

• In the European Economic Area, the UK and Switzerland, the app asks for your consent before personalised ads are shown, and you can change your choice at any time in the app’s settings.
• You can reset or delete your advertising ID in Android’s settings, under Privacy → Ads (the exact place varies by phone).

What we don’t do

• We do not sell your information, and we do not share it with anyone beyond what is described above.
• The app does not ask for your location, contacts, camera, microphone or accounts.
• We hold no data about you, so there is nothing for us to keep, hand over or delete.

Children

The app is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes

If the app’s handling of data changes, this page will be updated and the date at the top will change.
