Extension Metadata

About this extension
NUSMods Sync adds cross-device syncing and multiple timetable tabs to NUSMods.

• Automatically sync timetable changes between paired browsers.
• Save, rename, duplicate, reorder, and switch between multiple timetables.
• Share an encrypted, read-only timetable with friends.
• Overlay friends’ lessons and highlight shared classes.
• Restore recent timetable versions and handle conflicting edits.

No account is required. Timetable information is encrypted locally before being sent to the sync relay. The relay stores encrypted data and does not receive the encryption key.

NUSMods Sync does not collect analytics, advertising identifiers, credentials, payment information, or general browsing history. It only runs on NUSMods and connects to the NUSMods API and the NUSMods Sync relay.
