Lintel Privacy Policy

Last updated: 31 October 2026 (phone version added)

Lintel is an unofficial Chrome extension and phone userscript that gives students a faster way to use the room booking system of the Singapore Institute of Technology (SIT). It is not affiliated with, endorsed by, or operated by SIT.

The short version

Lintel has no server of its own and no analytics, advertising or tracking. It does not send your data to the developer or to any third party, unless you choose to submit a problem report.

What Lintel handles

Lintel only runs on rbs.singaporetech.edu.sg, in your own logged-in session. It reads and displays what that site already shows you, including:

• rooms, equipment, time slots and photos;
• your bookings and support requests;
• the names and IDs of people who booked a slot, where the site shows them.

Lintel never sees your password. It does not sign in for you, and login stays on the site itself. A booking or cancellation only happens when you confirm it.

Where your data goes

Requests go only to rbs.singaporetech.edu.sg, the same site you are already using. The only exception is a problem report, if you choose to submit one.

What is saved on your device

The Chrome extension uses Chrome's local extension storage. The phone version uses your browser's storage for the booking site. Both stay on your device and are not encrypted by Lintel. Lintel saves:

• your settings, such as theme and display mode;
• your most recent search and filter options;
• copies of your bookings and support requests, so pages open quickly;
• room photos and help page content.

Slot data that includes other people's names is kept in memory only and is cleared when the page closes.

Deleting your data

Uninstalling the Chrome extension removes everything it saved. On a phone, remove the userscript and clear your browser's site data for rbs.singaporetech.edu.sg.

Reporting a problem

The "Report a problem" link opens a Google Form, filled in with the Lintel build, the page you are on, and your browser details. You can edit any of it first. Nothing is sent unless you submit the form. Submitted reports are stored in Google Forms, under Google's privacy policy, and are used only to fix problems. Please do not include other people's names or IDs.

Sharing

Lintel does not sell or share your data, or use it for advertising, creditworthiness or lending. Its use of data is limited to providing the booking features described here.

Changes

If this policy changes, the date above will be updated.
