Privacy Policy
Last updated: September 19, 2026
This policy explains what YT Wallpaper (“the app”) and its sync service at api.ytwallpaper.com collect, why, and how you can remove it. The app works fully without an account; everything below applies only if you choose to sign in.
What we collect
- Account details from Google or Apple: your name, email address (Apple may give a private relay address) and profile picture URL, plus the account identifier and sign-in tokens the provider issues. We request only the basic
openid,emailandprofilescopes and never access your Google Drive, YouTube account, contacts or any other data. - Your Macs: the computer name, hardware model (for example “Mac15,3”), a random identifier the app generates, when each Mac was last active, and which wallpaper it is currently showing.
- Your wallpapers and saved videos: YouTube video IDs, titles, channel names, durations and the start/end times of your trims.
We do not upload or store video files, screenshots, your desktop contents, or your browsing history. We do not use analytics or advertising trackers.
How we use it
Solely to sign you in and to show the same wallpapers and saved videos on each Mac you use. We do not sell, rent or share your data with anyone, and we do not use it for advertising.
Google user data
YT Wallpaper's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Storage and security
Data is stored in a PostgreSQL database hosted by Railway. Connections use HTTPS. The access token the app keeps is stored in the macOS Keychain; the server stores only a SHA-256 hash of it, and tokens expire after 90 days without use.
Your choices and deletion
- Sign out in the app to revoke that Mac's access token.
- Remove another Mac from your account in the app's account panel.
- Deleting a wallpaper or saved video in the app deletes it from the server.
- To delete your account and all associated data, email thangpn19@gmail.com from the address you signed in with. We delete it within 30 days.
- You can also revoke the app's access at any time from your Google Account (Security → Third-party connections) or your Apple ID settings.
Children
The service is not directed to children under 13 and we do not knowingly collect their data.
Changes
If this policy changes, we will update the date above and post the new version here.
