Privacy Policy for Mainote
Last Updated: May 21, 2026
Welcome to Mainote, a cross-browser extension designed to help you capture and organize your thoughts efficiently. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our extension for Google Chrome and Mozilla Firefox.
We respect your privacy and are committed to protecting your personal data. Mainote is designed with data minimization in mind; your notes belong to you.
1. Information We Collect
A. Personal Data via Authentication
To synchronize your notes across devices, Mainote utilizes Supabase for user authentication. When you sign in using your Google Account, we receive:
Your email address
Your basic profile information (such as your name and profile picture URL)
This data is used solely to securely identify your account and maintain your user session.
B. User Content (Notes)
The text, titles, and timestamps of the notes you create are stored securely within our database infrastructure managed by Supabase. We do not read, analyze, or monetize your notes.
C. Extension Local Storage
Mainote uses chrome.storage.local to store local application settings, temporary session tokens, and cached configurations on your device.
2. Google API Data Usage (Google Drive Integration)
Mainote offers an optional cloud backup feature using the Google Drive API.
A. Scopes Requested
We request the specific, restricted
B. How We Use Google Drive Data
Limited Access: This scope ensures that Mainote cannot see, read, or modify your existing Google Drive files or folders. It only grants access to files that Mainote creates itself.
Backup & Sync: Mainote uses this permission exclusively to create, read, and overwrite a specific backup file (e.g., notes_backup.json) to allow you to manually or automatically export and import your notes.
No Sharing: Google user data obtained via this API is never transferred, sold, or shared with third-party tools, advertising platforms, or data brokers. It remains strictly inside your personal Google Drive environment and the extension.
3. How We Share Your Information
We do not sell, trade, or rent your personal information to others. Your data is only transmitted to the following essential infrastructure providers necessary to run the service:
Supabase / PostgreSQL: For securing your user account and hosting your database entries.
Vercel: For hosting our authentication handling code and web assets.
Google: To process OAuth logins and store your backup files on your command.
4. Data Security
We implement industry-standard security measures to maintain the safety of your personal information. All communications between the Mainote extension, Supabase, and Google Drive APIs are strictly encrypted using Transport Layer Security (TLS/HTTPS).
5. Your Choices & Data Deletion
You are in complete control of your data:
Local Backups: You can bypass cloud sync entirely and use the built-in local import/export feature to download your notes to a native JSON file.
Data Deletion: You may request the deletion of your account and all associated notes at any time by contacting us directly.
Revoking Access: You can revoke Mainote’s access to your Google Account and Google Drive at any moment through your Google Security Settings page (
https://myaccount.google.com/permissions ).
6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top.
