Website

The website must:

• be accessible at a public HTTPS URL without a VPN;
• have a valid certificate;
• work correctly on a phone;
• avoid redirect loops;
• load images, fonts, and other required resources without errors.

Test sign-in, payments, menus, external links, and permission requests on a real device. If part of the website requires sign-in, prepare a test account for store review.

For appearance requirements, see Icon and screenshots. If the website does not open in the app, use the troubleshooting instructions.
