Dev Toolkit does not collect, transmit, sell or share any data. There is no
analytics, no telemetry, no remote server, and no network request of any kind
made by this add-on. Everything happens locally in your browser.


Your settings (which features are on, the chosen font, the masking preset, the
export format, and so on) are saved with the browser's storage.local API.
That data stays on your device, is never uploaded, and is removed when you
uninstall the add-on.


| Capability | Why it is needed | Where the data goes |
|---|---|---|
| Access to websites (<all_urls>) | To restyle pages, force text direction, mask tab titles, repair garbled text, and render JSON responses | Nowhere. Processing happens in the page itself. |
| Tabs | To count and close tabs, and to know which site the panel is acting on | Nowhere. Shown to you in the panel only. |
| Cookies | To list, copy, export and delete cookies for the site you are on, when you ask for it | To your clipboard or a file you choose to save. Never uploaded. |
| Browsing data | To clear cache, storage and other site data when you press the button | Nothing is read; data is only deleted. |
| Downloads | To save the cookie export you requested to a file | Local file system only. |
| Scripting | To inject the stylesheet for the font and text direction, and to clear a site's local storage | Nowhere. |
| Clipboard write | To copy JSON, cookies, or a JSON path when you click Copy | Your clipboard only. |

Cookie values and page content are sensitive. They are only ever read in
response to an action you take, they are never stored by the add-on, and they
never leave your device.


None. The add-on bundles everything it needs, including the Vazirmatn font, so
it never contacts an external server.


If this policy ever changes, the updated version will ship with the add-on and
be published alongside it.
