Custom things to hide

Bring custom rules from another browser or teammate. The file is read in this browser and your logs are not uploaded.Download only your custom rules, never the log text, so you can reuse your cleanup setup later.

Add private names, tenant IDs, workspace IDs, emails, or patterns once. This browser remembers them for next time; export the rules before clearing browser data or moving to another device.
