Privacy

Last updated: July 16, 2026

What we store

• Your email address, from Google sign-in. Used to identify your account and nothing else.
• The video metadata you import: video IDs, titles, channel names, durations, and playlist positions from the Watch Later list you chose to export.
• AI classifications of those videos (category, one-line reason, confidence, topics).
• Your taste profile, if you filled in the optional quiz.

Your YouTube data

• Laterlist never receives your YouTube password, cookies, or session. The extension uses your signed in YouTube tab in your own browser.
• Your watch history, subscriptions, or any other YouTube data.
• The extension reads your Watch Later playlist. When you remove a video in Laterlist, it also removes that video from Watch Later if the setting is on. The setting is on by default when available, and you can turn it off in Settings. Nothing else on YouTube is changed.

The Chrome extension

The extension reads your YouTube Watch Later list when you sync, from your own signed in browser. It removes only the videos you clear in Laterlist when the setting is on. It sends video titles, channels, durations, and caption text to your own Laterlist account and nowhere else. Your access token is stored locally in your browser. The extension never reads other sites, never collects browsing history, and never sells or shares data.

How classification works

Video titles and metadata are sent to Anthropic's Claude API to be sorted into categories. Anthropic does not train on this data. No other third parties see your library.

Deleting your data

Settings → Delete everything removes your account and every imported video immediately and permanently. No grace period, no soft delete.
