The SignedText Helper extension is designed with a focus on privacy protection. It does not collect browsing history, track user behavior across websites, or collect personally identifiable information.

Operation Principle and Data Collection: To verify digital signatures on a visited page, the extension sends the following to SignedText.com servers:

Source code (HTML) of the current page;
Rendered text content of the page.


This data is necessary for the cryptographic verification of content integrity. The data may be temporarily stored on the server disk for processing purposes, but is not permanently archived. It is deleted after verification is complete.

Local Storage: User settings (e.g., preferred language or API token) are stored only locally in your browser and are not synchronized to our servers (with the exception of the API token, which is sent with the request for authentication).
