Each account window keeps its site’s cookies, storage and caches, sign-in included, in a WebKit store of its own. WebKit keeps it in files under your ~/Library, as a browser does. Account windows gives the paths.

What Pitboard does with a store

Pitboard never reads or copies what a site keeps there, and adds no script to a page. It never signs a window in with a Claude Code or Codex login. The app records each store and each window’s last page in windows.json, a file only you can read. It makes a store when the account’s window first opens. A renamed account keeps its store.

​
When a store is deleted

  • File > Remove Website Data wipes the store and signs the window out on this Mac only.
  • Forgetting the account deletes its store at the app’s next successful read of the accounts.
The app deletes a store only when its own Pitboard directory recorded it and no other existing one did. A copy run with another HOME or PITBOARD_HOME therefore signs no other copy’s windows out. While the app cannot read windows.json, it deletes no store. Pitboard’s Share extension takes the one web address a browser shares and checks that it is a claude.ai or chatgpt.com page. It hands the address to its app as a Pitboard link and keeps nothing. It is sandboxed, with no network, file or shared-folder access. The app checks the link again and opens nothing until you choose an account. It refuses the sites’ sign-in links, since one would sign the window in as whoever it belongs to. Refused links lists them.
