PUPSync Privacy Policy

Last updated: August 1, 2026

PUPSync is a Chrome extension that helps Polytechnic University of the Philippines (PUP) students work with their SIAS schedule and grades. This policy explains what data the extension accesses and how it is used.

Who we are

PUPSync is an independent student/alumni project and is not an official PUP product. Contact the developer via the Chrome Web Store listing support email.

Data we access

• SIAS pages on *.pup.edu.ph — When you open the extension on a schedule, grades, or home page, it reads information already shown in your browser (class schedule, grades, and your displayed student name) to show it in the popup.
• Google Calendar — If you choose Import to Calendar, PUPSync requests permission to create calendar events on your primary Google Calendar (calendar.events scope). Events are created only when you start an import.
• Local extension storage — Preferences such as subject colors, semester date overrides, a cached first name for greeting, and a temporary OAuth access token may be stored in Chrome’s local extension storage on your device.

What we do not do

• We do not operate a PUPSync backend server that receives your schedule or grades.
• We do not sell, rent, or share your personal data with advertisers.
• We do not use your Google account for advertising or unrelated Google APIs.
• We do not collect analytics beyond what Chrome or Google may show you in their own products.

How Google data is used

Calendar access is used solely to create recurring class events you preview and confirm. PUPSync’s use of Google user data complies with the Google API Services User Data Policy, including Limited Use requirements.

Data retention

Data stays on your device (Chrome storage) until you clear site/extension data, remove the extension, or revoke Google access at Google Account permissions. OAuth tokens expire and can be refreshed only when you use import again.

Children

PUPSync is intended for university students managing their own SIAS account. It is not directed at children under 13.

Changes

If this policy changes in a material way, we will update the “Last updated” date on this page and the version notes on the Chrome Web Store listing when applicable.
