Is Cipher completely free to use?

Yes! Cipher is 100% free to use. You can start chatting instantly without subscription fees, paywalls, or intrusive advertisements.

How does Passkey login protect my user account?

Cipher uses the FIDO2 WebAuthn biometric passkey standard (such as Touch ID, Face ID, or Windows Hello) alongside securely encrypted session tokens. This completely eliminates the threat of forgotten passwords, credential harvesting, and phishing attacks.

Why are photos and media loading so fast in Cipher?

Cipher features instant client-side canvas compression prior to transmission, paired with an optimized in-memory image caching system. This ensures that sent photos, media, and file attachments load and render instantly in sub-second times without lag or loading delays.

How do I install Cipher as a Progressive Web App (PWA)?

You can install Cipher by clicking the 'Install App' button in the navigation header or by choosing 'Add to Home Screen' in your mobile or desktop browser menu. When launched from your home screen, it functions as a native application with lightning-fast startups and real-time notifications.

Are high-definition voice and video calls supported?

Yes! Cipher provides high-definition, peer-to-peer voice and video calls powered by WebRTC. The system features dynamic noise reduction, echo cancellation, and adaptive bandwidth optimization for pristine quality even on slower connections.

Does Cipher support self-destructing or disappearing media?

Absolutely. Cipher includes granular privacy controls, allowing you to attach auto-destruct timers to sensitive media, ephemeral text messages, and stories. Expired content automatically vanishes from the local and cloud databases permanently once viewed.

Do I need a phone number to register an account on Cipher?

No, Cipher is built for maximum privacy and accessibility. You can register and log in securely using biometric passkeys, custom usernames, or secure login credentials without ever sharing or exposing your personal phone number.
