Local Browser Processing & Privacy
Traditional web converters upload your documents, snippets, or media files to remote servers. Cron Expression Humanizer & Timeline runs inside your browser tab:
Your input text and files are processed locally without uploading payloads to a processing server.
Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).
Working outputs stay in your browser tab and are released when you reset the tool or close the tab.
