Notes Stack

Privacy Policy

Last updated: February 9, 2026

Notes Stack stores all your data locally on your device. We do not collect, transmit, or have access to any of your notes, tasks, or personal information.

Overview

Notes Stack is a browser extension designed to help you capture notes, tasks, and reminders directly from your browser side panel. Privacy is at the core of how we built this extension — your data never leaves your device.

Data Storage

All data created within Notes Stack is stored locally on your device using your browser's built-in storage mechanisms:

  • Notes, tasks, and stacks are stored in IndexedDB, a database built into your browser.
  • Preferences (theme, color scheme) are stored in the browser's local storage.
  • PIN protection uses a one-way hash stored locally. Your actual PIN is never stored in plain text.

No data is sent to any external server, cloud service, or third party. We have no servers and no backend infrastructure.

Data Collection

Notes Stack does not collect any data. Specifically:

  • No analytics or telemetry
  • No usage tracking
  • No personal information collection
  • No cookies or third-party tracking scripts
  • No advertising identifiers

Browser Permissions

Notes Stack requests the following browser permissions, each used solely for core functionality:

  • sidePanel — Required to display the notes interface in the browser side panel.
  • storage — Required to save your preferences and settings locally.
  • tabs and activeTab — Required to associate notes with the webpage you are currently viewing, so notes appear when you return to that page.
  • alarms — Required to schedule reminder notifications at the times you set.
  • notifications — Required to display reminder notifications when they are due.

These permissions are used exclusively for the features described above and nothing else.

Data Export

Notes Stack allows you to export your data as a CSV file. This export is entirely user-initiated — data is generated locally and saved to your device. No data is transmitted during the export process.

Data Deletion

You can delete individual notes, stacks, or all data at any time from within the extension. Uninstalling the extension will also remove all locally stored data. Since we do not store any data externally, there is nothing to delete on our end.

Third-Party Services

Notes Stack does not integrate with or send data to any third-party services. The extension works entirely offline after installation.

Changes to This Policy

If we make changes to this privacy policy, we will update the "Last updated" date at the top of this page. Significant changes will be communicated through the extension's update notes.
