Privacy Policy
Last updated: October 5, 2026
The short version
We collect nothing. Lattice has no accounts, no sign-in, and no server or database of its own. It never asks for your VTOP password.
What stays on your device
- Your subjects — stored in your browser's own storage (IndexedDB). They're never sent to us or anyone else.
- The app's files — saved by your browser so Lattice opens fast and works offline.
- Timetables are generated on your device. Nothing you enter leaves it.
What we don't do
No cookies, no analytics, no advertising, no trackers, no third-party fonts or scripts. We don't sell or share data — we don't have any.
Links to other sites
Links to Instagram, LinkedIn, or email open those services, which have their own privacy policies.
Deleting your data
Delete a subject in the app, or clear this site's data in your browser settings to remove everything at once. If you installed Lattice as an app, choose to clear its data when you uninstall it.
Changes
If this policy changes, the date above will change with it.
