Google and YouTube data
Watch Later Manager uses YouTube API Services and requests permission to view and manage your YouTube account. It accesses playlist names and IDs plus video IDs, titles, channels, thumbnails, durations, dates, and playlist order. The app uses this data only to find or create your private __WL__ playlist, display it to you, and perform the add, remove, refresh, and reorder actions you request.
Storage and processing
Your Google OAuth access and refresh tokens and __WL__ playlist ID are encrypted in a secure, HTTP-only cookie that expires after one year. Your browser sends that cookie to the app over HTTPS so the Vercel-hosted server can call Google on your behalf. Tokens are decrypted only in server memory and are unavailable to browser JavaScript. The app has no user database and does not persist your playlist or video data on its server.
Sharing
The app does not sell your Google user data, use it for advertising, or share it with other users. Data is transmitted only to Google and YouTube to fulfill your requests and to Vercel as the app’s hosting provider. Vercel may retain standard operational logs under its own policies.
Retention and deletion
Playlist and video data is fetched fresh from YouTube and retained only in your current browser page. Disconnecting YouTube deletes the encrypted session cookie. To revoke the app’s access at Google, remove Watch Later Manager from your Google Account permissions.
Google policies
Use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements. Google’s handling of data is described in the Google Privacy Policy.
