SubLib: Privacy Policy
Last updated: 26 October 2026
SubLib organizes your YouTube subscriptions into folders. It is not made by, endorsed by or affiliated with YouTube or Google.
What SubLib accesses
When you sign in with Google, SubLib asks for read-only access to your YouTube account (the youtube.readonly permission). It uses it only to read the list of channels you subscribe to, the topics YouTube gives those channels (when you ask SubLib to suggest folders), and the length and upload lists of their videos. SubLib never posts, likes, comments, subscribes or unsubscribes for you.
SubLib also reads your name, email address and profile picture from Google to show them in the app.
How SubLib uses it
SubLib uses this data only to show you your own subscriptions, sort them into folders, suggest folders, and show new videos from your channels. It is not used for anything else.
Where your data is kept
Everything SubLib stores (your channel list, folders and their cover images, watched videos and saved videos) stays on your phone. SubLib has no server and does not send your data to the developer or to anyone else. New videos are loaded directly from YouTube's public channel feeds. If Android backup is on for your phone, Android may include SubLib's data in your own Google account backup.
SubLib has no ads, no analytics and no tracking, and does not sell or share any data with anyone.
How your data is protected
Your Google data never leaves your phone except to talk to Google: SubLib connects only to Google and YouTube, always over encrypted HTTPS connections. The sign-in token Google gives SubLib is kept in the app's private storage on your phone, which other apps cannot read, and it expires after about an hour. Signing out removes it, and "Delete all SubLib data" also cancels it at Google. SubLib never sees or stores your Google password.
SubLib does not create any aggregated or anonymized data from your Google data.
How long data is kept
Data read from YouTube is refreshed or deleted within 30 days. Your folders and settings stay on your phone until you delete them, sign out and delete your data, or uninstall the app.
Deleting your data
In SubLib, open Settings and choose "Delete all SubLib data". This removes everything from your phone, signs you out and takes back SubLib's access to your YouTube account. Uninstalling the app also removes it. Because we keep no copy, there is nothing else to delete. You can also remove SubLib's access at any time at https://myaccount.google.com/permissions
Limited Use
SubLib's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Your Google data is used only to provide SubLib's features to you. It is never used for advertising, never sold, never transferred to anyone else, and never used to train AI or machine learning models.
Purchases
SubLib Pro is bought through Google Play. Google handles the payment; SubLib never sees your card or payment details. The app only asks Google Play whether your account owns SubLib Pro.
YouTube and Google
SubLib uses YouTube API Services. By using SubLib you agree to the YouTube Terms of Service. Google's handling of your data is described in the Google Privacy Policy.
