API Testing PRO — REST & HTTP Client by Zovo
Last updated: February 11, 2026
We collect absolutely no data. Zero. None.
When you use API Testing PRO:
storage: Saves your request history, user preferences, and saved API collections locally so you can access previous requests after closing and reopening the browser.
sidePanel: Provides a larger workspace in the browser side panel for composing complex API requests and viewing detailed response data without leaving the current tab.
contextMenus: Allows you to right-click selected text (such as URLs or JSON) and quickly send it to API Testing PRO for testing.
activeTab: Enables the context menu to access the current tab's URL or selected text (such as API endpoints or JSON payloads) when you right-click and choose to send it to API Testing PRO. No data is read without explicit user action.
API Testing PRO does not use any remote code. All JavaScript is bundled within the extension package. No external scripts are loaded or executed.
All data is stored locally using Chrome's storage API:
This data never leaves your browser and is not accessible to us.
API Testing PRO does not integrate with any third-party services, analytics platforms, or tracking tools.
If we ever change this policy, we'll update this page with the new date.
