Privacy policy
Last updated 29 August 2026.
tubem3 is a personal YouTube client that runs entirely on your own device. This policy describes what it handles and what leaves the device. It is short because the application does little that needs describing.
1. There is no server, and no account with us
tubem3 talks to YouTube’s API directly from your device, using your own Google sign-in. We operate no service that your use of the application passes through. We do not have an account for you, we cannot see what you watch, and there is nothing for us to hand over or lose.
2. What is stored, and where
Everything the application knows is kept in a database on your device, encrypted with a key held in the device’s own secure keystore. That includes:
| Data | Why it exists |
|---|---|
| Your subscriptions and the videos in them | To show the feed without asking YouTube again on every scroll |
| What you have watched, and how far | To resume, and to hide what you have finished if you ask it to |
| Your rules, filters and parental settings | They are the point of the application |
| Your Google access and refresh tokens | To stay signed in without asking again |
None of it is transmitted to us or to anyone else.
3. What the application asks Google for
| Permission | What it is used for |
|---|---|
youtube.readonly | Reading your subscriptions, playlists and video details. Requested when you sign in. |
youtube.force-ssl | Only requested if you ask the application to change something — create or edit a playlist. It is not requested at sign-in. |
The application asks for the narrower permission first and the wider one only when you use a feature that needs it.
4. What we do not do
- No analytics. No usage statistics, no event tracking, no advertising identifiers.
- No crash reporting to a third party. Errors are written to a log on your device, which you can read.
- No profile of you. Recommendations, where offered, are computed on your device from your own history and are never sent anywhere.
- No cookies or trackers on this website. These pages load nothing from another host.
5. The parts that are not absolute
Two honest qualifications, because a policy that claimed perfection would be untrue:
- YouTube sees your requests. The application fetches from Google’s servers and plays video through YouTube’s own embedded player. Google therefore sees that activity, under Google’s own privacy policy, exactly as it would if you used YouTube directly. We have no control over that and do not claim otherwise.
- This website keeps ordinary web-server logs. If your device fetches an update from this domain, the server records the request in the usual way — including the IP address it came from — for operating the site. Those logs are not linked to any account, because there are no accounts.
6. Deleting your data
Signing out revokes the application’s access to your Google account and clears the stored tokens. Uninstalling the application removes the encrypted database and everything in it. Neither requires our involvement, because we hold nothing.
You can also remove tubem3’s access at any time from your Google account permissions.
7. Children
tubem3 includes a parental gate and a kids mode, which restrict what can be browsed and played on a shared device. These are local settings on that device and involve no data leaving it.
8. Changes
If this policy changes, the date at the top changes with it.
