Messages That Unlock by Location - Secure messages that unlock only in specific locations

by•
City of Hats is a secure messaging platform introducing location-controlled communication. Senders can lock messages so they only open inside a specific geographic area, verified through telecom network signals or GPS. Combined with features like View Once, Invisible Watermark, biometric access, and recall, messages can have strict access conditions. Available on Google Play and Microsoft Store, with iOS coming soon.

Hi Product Hunt! I’m Stephane, founder of City of Hats. We built this because we wanted messages that could have real-world conditions — for example, only opening inside a specific location. I’d love your feedback on secure messaging and how people might use location-locked communication.
