Nexus Highlighter Privacy Policy

Last updated: August 17, 2026

This Privacy Policy explains how Nexus Highlighter collects, stores, uses, and transmits data when you use the Chrome extension.

Single Purpose

Nexus Highlighter helps you highlight and annotate text on webpages, manage your saved highlights, reopen original sources, sync your highlights after registration, and export your own research notes.

Data Stored On Your Device

Nexus Highlighter does not save data just because you visit a webpage. The content script runs on webpages so the extension can offer highlighting tools and restore highlights that you previously saved for that page.

When you create or manage a highlight, the extension stores the following in Chrome extension storage on your device:

Highlighted text selected by you.
Surrounding text used to relocate the highlight if the page changes.
Notes, tags, color, pinned state, and archived state that you add.
Page URL, canonical URL, page title, domain, and favicon URL for pages where you created highlights.
Creation, update, and deletion timestamps.
Extension settings such as default highlight color and cloud sync preference.
License and account status returned by CodersNexus after login or license verification.

Data Sent Off Your Device

Extension Login

If you choose to register or log in through CodersNexus, Nexus Highlighter opens a secure CodersNexus login page using Chrome Identity. CodersNexus returns a one-time authorization code to the extension, and the extension exchanges that code for an extension token. In this product, that token is a license key used to identify your Nexus Highlighter entitlement.

This login flow is used to raise the free highlight limit, attach the extension to your CodersNexus account, verify access, and enable cloud sync for connected accounts.

License Verification

The extension sends the stored license key and fixed Nexus Highlighter product identifier to the CodersNexus backend to check whether the license is valid. This can happen when a key is activated, when the popup opens, before premium actions, when Chrome starts, and before cloud sync requests.

Cloud Sync

Cloud sync is on by default for connected CodersNexus accounts. When cloud sync is enabled, your highlights, notes, tags, page URLs, canonical URLs, page titles, domains, favicon URLs, colors, pinned/archived state, and timestamps are sent to the Nexus Highlighter sync backend so they can be backed up and restored across your Chrome installations for the same CodersNexus account.

You can turn cloud sync off in the extension popup. If cloud sync is off, highlights remain local to your browser and are not sent to the sync backend.

Data We Do Not Collect

No payment card or banking information is collected by the extension.
No location, contacts, health data, or financial data is collected.
No advertising identifiers are collected.
No analytics SDK or ad network is included in the extension.
No browsing history is stored beyond pages where you explicitly create a highlight or note.
No webpage content is collected unless you select text and save it as a highlight or note.

How Data Is Used

Data is used only to provide Nexus Highlighter's user-facing features:

Saving and restoring highlights.
Managing notes, tags, colors, source pages, and highlight lists.
Opening original webpages linked to saved highlights.
Verifying registration, license, and premium access.
Syncing highlights for connected CodersNexus accounts when cloud sync is enabled.
Exporting highlights when the user chooses an export action.
Providing support, troubleshooting, fraud prevention, security, and legal compliance related to the product.

Nexus Highlighter does not sell user data and does not use user data for advertising.

Nexus Highlighter sends data only to CodersNexus services needed to provide the extension:

CodersNexus account and license services for login and license verification.
Nexus Highlighter sync services for cloud backup and restore.

Data may be processed by infrastructure providers used to host CodersNexus and Nexus Highlighter services. Data is not sold, rented, or shared with advertising networks or data brokers.

Data Retention And Deletion

Local highlights, notes, page records, settings, and license state remain in Chrome extension storage until you delete them, disconnect/reset the extension, or uninstall the extension.

If cloud sync is enabled, synced records remain on the backend until they are deleted through the product or your CodersNexus account data is removed according to the CodersNexus account deletion process.

Security

Nexus Highlighter transmits data to CodersNexus and Nexus Highlighter services over HTTPS. License keys and extension tokens are stored in Chrome extension storage and are used only for extension login, access verification, and sync authorization.

Limited Use Disclosure

The use of information received from Chrome APIs by Nexus Highlighter adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used solely for the extension's disclosed user-facing highlighting, annotation, management, login, license verification, sync, export, security, and support functionality.
