This Privacy Policy describes how Chrome Extensions by Tets , including Helper by Tets and Tech Util by Tets, handle user information.
These extensions do not collect, sell, or transmit personal data to the developer or any third party.
Functionality is performed locally within your browser unless a feature specifically opens or interacts with a page or API you are already using.
Utility features such as JSON formatting, XML formatting, XML to JSON conversion, JSON to CSV conversion, and URL encoding or decoding are processed locally in your browser.
Input entered into these tools is not sent to any external server by the extension.
Some Publica-related tools may use authentication context already present in your active Publica browser session in order to open helper pages or make requested Publica API calls.
This authentication context is used only within your browser to support the requested tool functionality. It is not sent to the developer or to unrelated third parties.
Since these extensions do not collect personal data, no personal data is used, sold, or shared by the developer.
These extensions do not share user data with third parties.
The Publica-focused extension may interact with Publica pages or Publica APIs when you use Publica-related helper tools.
The Tech helper extension does not use third-party services for its conversion, formatting, encoding, or decoding tools.
These extensions are designed to minimize data handling. Technical helper inputs are processed locally, and Publica-related functionality uses only the browser session context needed to perform the requested action.
This Privacy Policy may be updated from time to time. Any changes will be reflected on this page.
