Last updated: January 7, 2026

Introduction

Threadmark ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application, browser extension, and website (collectively, the "Service").

Information We Collect

Account Information

When you create an account, we collect:

  • Email address
  • Name (from your Google account if you sign in with Google)
  • Profile picture (from your Google account if you sign in with Google)

Bookmark Data

When you use the Service, we collect:

  • URLs you save as bookmarks
  • Page titles and descriptions
  • Notes and comments you add to bookmarks
  • Collections you create and their sharing settings
  • Messages you send in shared collections

Usage Information

We automatically collect certain information when you use the Service:

  • Device information (device type, operating system)
  • Log data (access times, features used)
  • Push notification tokens (for sending notifications)

How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve the Service
  • Create and manage your account
  • Sync your bookmarks across devices
  • Enable collaboration features with other users
  • Send you notifications about activity in your collections
  • Respond to your comments, questions, and requests
  • Monitor and analyze trends, usage, and activities

Information Sharing

We do not sell your personal information. We may share your information in the following situations:

  • With other users: When you share collections or collaborate with others, they can see the bookmarks, comments, and messages you share
  • Service providers: We use third-party services (such as Supabase for data storage and Google for authentication) that may process your data on our behalf
  • Legal requirements: We may disclose your information if required by law or in response to valid legal requests

Data Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

Data Retention

We retain your personal information for as long as your account is active or as needed to provide you the Service. You can delete your account at any time, which will remove your personal data from our systems. Some information may be retained in backups for a limited period.

Your Rights

Depending on your location, you may have certain rights regarding your personal information:

  • Access and receive a copy of your data
  • Correct inaccurate personal information
  • Request deletion of your personal information
  • Object to or restrict certain processing
  • Data portability

To exercise these rights, please contact us using the information below.

Browser Extension

Our Chrome extension accesses the current tab's URL and title only when you choose to save a bookmark. The extension uses Google Sign-In for authentication. The extension periodically checks for new notifications to update the badge count. We do not track your browsing history or collect data from pages you do not explicitly save.

Children's Privacy

The Service is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we learn we have collected personal information from a child under 13, we will delete that information.

Changes to This Policy

We may update this 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.
