Navmark Extension — Privacy Policy

Effective Date: November 1, 2025
Product: Navmark Browser Extension
Developer: Applied Information Design (Portland, Oregon)
Notice of Name Change: Navmark is the current name of the browser extension formerly known as “Tabmark”. This policy applies to the same software under its current name.

1. Overview

Navmark is designed with privacy as a core principle.

The extension keeps your bookmarks, tab information, and browsing behavior on your device, unless you choose to share selected information with external services.

We do not collect analytics, tracking data, or personal usage metrics, and we collect personal information only when required to provide a paid license that the user explicitly activates.

This Privacy Policy describes what the extension does and does not transmit.

2. Data Stored and Processed Locally

Navmark stores all functional data locally on your device, including:

  • Bookmarks
  • Folder structures
  • Tab information
  • Browsing activity used by the extension

We do not collect or transmit:

  • Browsing history
  • Click data
  • Usage behavior
  • Interaction logs
  • Bookmark or tab content

Note on Browser Sync
Navmark reads the bookmarks already stored in your browser in order to display and organize them.

Many browsers offer optional built-in sync features (such as Chrome Sync, Firefox Sync, Edge Sync, or Brave Sync) that may store your bookmarks or settings in the vendor’s cloud services.

These sync services are operated solely by the browser vendor and are subject to their respective privacy policies.

Navmark does not transmit your bookmarks to any external server, and it does not control, manage, or modify how any browser vendor handles synced bookmark data.

All processing performed by Navmark itself remains local to your device.

3. Favicon Retrieval

When displaying bookmarks, your browser may retrieve website icons (“favicons”) from Google’s favicon service.

During this process:

  • Your device’s IP address may be visible to Google.
  • Navmark does not send any data to Google beyond the standard favicon request made by the browser.
  • If a favicon is not available, Navmark displays a locally generated fallback icon.

Navmark does not transmit any personal data during favicon retrieval.

4. Optional AI Assist and External Queries

Navmark includes optional tools that allow you to send information—such as search queries or selected bookmark data—to external services (e.g., search engines or large-language-model APIs).

Important safeguards:

  • Nothing is transmitted automatically.
  • Only bookmarks or text you explicitly select are sent.
  • You must initiate each action manually.
  • You should review the privacy policies of any external services you choose to use.

5. License Validation (Pro Version Only)

The only personal information collected by Navmark is an email address provided by the user for license validation of the Pro version.

The Pro version validates your license using a secure connection to our server.

For this purpose, the extension may send:

  • Your email address
  • Your license code
  • A non-reversible hash of your license key
  • A non-reversible hash of your device identifier

We do not collect:

  • Bookmark contents
  • Browsing history
  • Tab activity
  • IP addresses
  • Analytics
  • Usage statistics beyond device-count enforcement

This information is used solely to:

  • Confirm license validity
  • Enforce fair personal use
  • Prevent abuse such as publicly shared license keys

6. No Collection of Content or Behavior

Navmark does not collect, store, or transmit:

  • The content of your bookmarks
  • Which bookmarks you click
  • Your tab activity
  • Your browsing history
  • Your usage frequency or patterns

All data remains on your device unless you intentionally choose to share specific items.

Except for license validation, Navmark does not collect, store, or transmit personal information.
