Tool input and results

Mail headers, raw MIME, message text, attachments, Linux command inputs, hostnames, IP addresses, paths, certificates, CSRs, PEM and Private Keys are processed in browser memory. The tool application does not upload these inputs or results to a Yoonadev server or save them in a server database.

Selecting an attachment reads it locally to build MIME. Certificate processing and key generation use a browser Worker and Web Crypto. The application does not log your raw input to the browser console or send it as an analytics or error-reporting payload.

Private Keys, copying and downloads

A generated Private Key is created in your browser and is hidden in the result until you choose to display it. Copying and downloading happen only when you request them. Save a needed key safely: Yoonadev cannot recover it after the page is closed.

Editing inputs clears previous results. Clearing or leaving a tool releases its inputs and results from the application. Browser internals, downloaded files and the operating-system clipboard are outside this clearing mechanism; it is not a secure memory erasure guarantee.

Browser preferences and navigation

Local storage holds your language choice, favorite tool IDs and recent tool IDs with visit times. Session storage holds menu expansion and scroll state. These preferences do not contain raw tool input. Clear this site’s browser data to remove saved preferences.

Permission tools can pass a three-digit permission mode, such as 755, in a related-tool link. Language links may include a language query parameter. Those URL parameters are part of normal page requests. Raw mail, files and keys are not put into links by the tools.

Website and hosting requests

The public site is hosted using Cloudflare static assets. Loading a page, script or Worker makes ordinary web requests; these are separate from processing tool input. Cloudflare receives connection information such as your IP address, requested URL and HTTP headers to deliver and protect the site. Its handling of request and network data is described in its own privacy policy.

The application code does not set cookies or include its own analytics, advertising or remote error-reporting script. This describes the application, not a claim that hosting infrastructure processes no data.

Advertising and changes

This version does not include AdSense or another advertising service. If advertising or data handling changes, this notice will be updated to describe the service and any applicable choices before it is introduced.
