Privacy Policy
Effective Date: March 25, 2026
ALT-DEV TOOLS does not collect, store, transmit, or share any user data whatsoever.
1. Overview
ALT-DEV TOOLS is a Chrome DevTools sidebar extension that provides enhanced web development debugging capabilities directly within your browser. The extension operates entirely on your local machine and does not communicate with any external servers.
2. Data Collection
We do not collect any data. Specifically:
- No personal information is collected
- No browsing history is recorded or transmitted
- No cookies or website data leaves your browser
- No analytics or tracking scripts are included
- No telemetry data is gathered
- No crash reports are sent
- No user behavior is monitored
3. Data Usage
All data processed by ALT-DEV TOOLS exists solely within your browser session:
- DOM data — Inspected only in the active tab for display in the Elements panel
- Console logs — Captured from the active tab and displayed locally
- Network requests — Intercepted from the active tab for display in the Network panel
- Cookies & Storage — Read from the active tab for display in the Application panel
- Page source — Read from the active tab for display in the Sources panel
None of this data is ever transmitted outside your browser. All data is discarded when you close the DevTools panel or navigate away from the page.
4. Permissions Justification
The extension requests the following Chrome permissions, each used exclusively for local development tool functionality:
| Permission | Purpose |
|---|---|
activeTab |
Access the currently inspected tab to read DOM, styles, console output, and network activity for display in the DevTools sidebar panels |
cookies |
Read cookies from the inspected page to display them in the Application panel's Cookies section — read-only display for debugging |
scripting |
Inject content scripts into the inspected page to capture DOM structure, console output, network requests, and page source code |
sidePanel |
Display the extension's developer tools UI as a Chrome sidebar panel |
storage |
Persist user preferences such as theme selection and panel layout settings locally using chrome.storage.local |
tabs |
Query tab information (URL, title) to associate debugging data with the correct tab and detect page navigation |
host_permissions |
Required to inject content scripts into any webpage the developer is inspecting — the extension must work on all websites |
5. Remote Code
ALT-DEV TOOLS does not use any remotely hosted code. All JavaScript and CSS is bundled within the extension package. The chrome.scripting.executeScript() API is used solely to inject the extension's own bundled content scripts into the inspected page.
6. Third-Party Services
The extension does not integrate with, connect to, or communicate with any third-party services, APIs, or servers. There are no external dependencies at runtime.
7. Data Storage
The only data stored by the extension is user preferences (theme, layout) saved locally via chrome.storage.local. This data:
- Never leaves your device
- Contains no personal information
- Can be cleared by uninstalling the extension
- Is not accessible by any website or third party
8. Data Sharing
We do not share any data with any third parties. Since no data is collected, there is nothing to share, sell, or transfer.
9. Children's Privacy
ALT-DEV TOOLS does not collect any data from any users, including children. The extension is a development tool intended for web developers.
10. Changes to This Policy
If we update this privacy policy, the changes will be reflected on this page with an updated effective date. Since the extension collects no data, significant changes are unlikely.
11. Contact
If you have questions about this privacy policy, please open an issue on the extension's repository or contact the developer through the Chrome Web Store listing.
