Where do I host the file?

At https://yourdomain.com/.well-known/apple-app-site-association with no file extension, served as application/json over HTTPS with no redirects.

Where do I find my Team ID?

It is the 10-character App ID prefix shown in your Apple Developer account membership page.

How do I exclude a path?

Prefix the pattern with NOT, for example NOT /admin/*, and it becomes an excluded component.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
