Need help with an
A1 Local extension?

Send a short note with the extension name, what you expected to happen, what happened instead, and your browser version if you have it handy.

Before emailing

  • Reload the page you are checking and run the extension again.
  • Check that the extension is enabled in your browser.
  • Try on a normal public page, not a browser settings page or extension-store page.
  • Include a screenshot if the popup shows an error.

Privacy

The current builds are local-first. They do not send scan results, page content, timing data, font samples, tab workspaces, or browsing history to A1 Local.
