Occulta

Occulta is an iOS app that functions as a secure contact book where each entry is a cryptographic key exchanged in person via Ultra-Wideband (UWB). It enables users to encrypt files and messages specifically for their contacts, ensuring privacy without relying on servers, accounts, or phone numbers. It incorporates advanced security features such as forward secrecy, post-quantum encryption, duress PINs, and secret sharing for data recovery, targeting professionals and activists who need to protect sensitive information.
