A fully-featured, multi-persona chat app which lets you take full control of your privacy. Modeling Real-life Relationships and Interactions with Multiple Personas Personas are different aspects of our character that we choose to share with different people, e.g. to families, to friends, to co-workers, to strangers. OpusChat is a chat app which supports personas. In addition to the features one would expect from a chat app, you could create and use multiple personas in one seamless app. Each persona is seen by others as a completely different profile. You can customise how you present yourselves and manage each relationship. You could protect and control your privacy when messaging or calling contacts using different personas, as well as apply specific preferences for each persona. Full control over your data and privacy * Make friends with a unique ID, QR code or phone contact matching (only when phone numbers appear in phone contacts of both users) * Connect to people you really know * Eliminate any unsolicited phone calls or messages * Full control over how you interact with each other, what others can see, share or receive * Customise settings for each relationship How is OpusChat different from other popular chat apps? * True multi-persona support - switch between personas easily without having to 'sign-in/sign-out' * Manage your social network easily & without hassle * Strong emphasis on privacy: - We don't ask you for your phone number (unless you choose to use it for account recovery or friend matching) - We don't ask you for your email (unless you choose to use it for account recovery reasons) Features: * Easily switch between different personas in a single app with a single tap * Secure multimedia messaging features (text, photos, videos, voice recordings, locations, etc) * Free high quality, secure voice calls * Customise name, photo, preference and privacy settings for each persona * Accept/reject voice calls and voice notes down to per user level * Set the size and clarity of media preview – large vs small and clear vs blur Security: * End-to-end encrypted, with forward secrecy * Messages are stored on our servers encrypted until they are delivered * No tracking of user experience data 100% Free.
