Third-party requests
When you open an event map, your browser requests map tiles from OpenStreetMap and that service may receive your IP address. Venue address searches are made by Shake-on’s server. Shake-on fonts are served from its own site.
You can clear or block browser storage in your browser settings. If you block sign-in storage, you will be signed out; if you block the offline roster, offline check-in will not work.
