Privacy Policy

Effective: June 2026 · Marksheet v1.0

Marksheet does not collect, store, or transmit any of your personal data. There is no backend server, no database, no analytics, and no telemetry of any kind.

What Marksheet can and cannot do

✅	Write rows to the Google Sheet you choose
✅	Read URLs from that sheet to detect duplicates
❌	See any other files in your Google Drive
❌	Access your Google account details or profile
❌	Send your data to any server or third party
❌	Track what pages you visit
❌	Run analytics or telemetry of any kind

Data stored on your device

The following is saved in your browser's local storage only. It never leaves your machine. Uninstalling the extension deletes it permanently.

Your sheet configurations — spreadsheet URL, tab name, column layout
A cached list of URLs already saved, used for instant duplicate detection
A short-lived Google OAuth token issued by Google, expires automatically

Google account access

Marksheet requests a single Google OAuth scope:

https://www.googleapis.com/auth/spreadsheets Read and write access to Google Sheets only. No Gmail, no Drive, no Calendar, no profile data.

You can revoke this access at any time at myaccount.google.com/permissions.

How data flows

When you click save, your browser sends the tab URL, title, and timestamp directly to the Google Sheets API using your own credentials. The data goes from your browser to your sheet — nowhere else.

Third parties

Marksheet has no third-party dependencies, no tracking scripts, and no CDN calls at runtime. The only external service it communicates with is the Google Sheets API.
