Your data stays yours.
The short version: the tools run locally, and there are no analytics or advertising trackers in this version of the site.
Browser tools
Text, JSON, tokens, and passwords entered into the available Lab tools are processed in your browser. The site does not upload or intentionally persist these inputs. Leaving or refreshing a tool page clears its in-memory state; your browser may still restore form values or keep copied text in its clipboard.
Theme preference
If you change the color theme, the site stores your choice in local storage under lab-theme. This lets the theme stay consistent on your next visit. You can remove it by clearing this site’s browser data.
Game records
Packet Patrol saves your best move count and completion time for preset levels, variants and daily challenges in local storage under lab-packet-patrol-v1. Records stay in this browser and are not uploaded. Clear this site’s browser data to remove them. The game also works without storage.
Up to 42 game records are kept. Sound is off by default and generated in your browser when enabled. Sharing copies a result only when you ask; no result is posted automatically. Workbench demos and terminal commands run in memory in your browser and are cleared on reload.
Friday Deploy stores up to three personal best results (hints used, configuration changes and time) under lab-friday-deploy-v1. Its terminal and network are simulations running in your browser. Commands are not sent to a server, and in-progress incidents reset on reload.
Hosting and external links
Like any website, the hosting infrastructure may process connection information such as an IP address, requested URL, and user agent in access or security logs. Retention depends on the hosting provider and deployment configuration. External sites linked from here have their own privacy practices.
