Privacy Policy

Last Updated: March 8, 2026

Data Collection

Excalivault is a privacy-focused extension. We believe in local-first data storage.

What We Collect

We do NOT collect any data. Period.

Your drawings and folders are stored only in your browser's local storage (chrome.storage.local). Your data stays on your device:

  • ✅ No servers - your data never leaves your device
  • ✅ No tracking - we don't track usage or analytics
  • ✅ No personal data - we don't collect personal information
  • ✅ No cookies - we don't use cookies or third-party tracking

What Data Is Stored Locally

All data stays on your device:

  • Drawings - Elements, app state, and thumbnails
  • Folders - Organization structure
  • Settings - Your preferences

This data is never transmitted outside your browser.

Permissions Required

Excalivault requests minimal permissions to function:

Purpose: Save drawings and folders locally

Data Access: Only your own Excalidraw data

Network Access: None (data never leaves your device)

Third-Party Services

Excalivault does not use any third-party services, APIs, or analytics.
