No phone number or email required for core Hat use.

The useful difference
Choose the location and supported radius in the sending flow.
Use location as an additional access condition for suitable content.
Location permission, accuracy and client support affect the recipient’s experience.
How it works
Select the image or file in your Hat channel.
Enable GeoLock and review the location and radius.
Tell the recipient where viewing is permitted and check that their device supports the flow.
Know the boundary
GeoLock is an app/service access control, not a guarantee of physical presence. Device compromise, spoofing and poor positioning affect assurance. Location parameters are part of the workflow; do not assume that no location-related data reaches service components. Copies kept after viewing remain outside the lock.
