IsoToxin is the ultimate secure messaging application designed for those who demand absolute privacy: it completely safeguards your metadata, delivers true end-to-end encryption for every conversation, and guarantees total anonymity in all your messaging interactions. From the moment you send a message to the second it’s received, no phone numbers, emails, IP addresses, or behavioral patterns are ever collected or exposed – not by IsoToxin and not by anyone else. With battle-tested cryptographic protocols, automatic EXIF stripping, mutual-contact calling, and zero-knowledge architecture, IsoToxin ensures your communications stay 100% private, untraceable, and fully under your control in an era where real digital privacy is exceptionally rare.

With IsoToxin, true privacy starts from the very first step: creating an account requires no phone number, no email address, and no personal identifiers whatsoever. You’re free to use your real name, a creative pseudonym, or anything in between as your display name – the choice is entirely yours. Unlike most messaging apps, IsoToxin collects zero metadata, zero device identifiers, and absolutely no information that could ever link your activity back to you. Your identity, contacts, and communication patterns remain completely anonymous and protected, giving you total control and genuine peace of mind in a world where privacy is increasingly rare.

IsoToxin delivers unbreakable privacy and military-grade security through true end-to-end encryption that keeps your conversations completely private and inaccessible to anyone else – not even IsoToxin itself. Every message is protected by the advanced Double Ratchet Algorithm, the same battle-tested encryption technology trusted by Signal and WhatsApp for billions of users worldwide, ensuring perfect forward secrecy and self-healing security. For crystal-clear voice and video calls, IsoToxin employs the industry-standard DTLS-SRTP protocol, providing fully encrypted real-time communication that prevents eavesdropping and man-in-the-middle attacks. With these proven, gold-standard cryptographic protocols powering every interaction, IsoToxin guarantees that your personal and professional communications remain confidential, secure, and truly private in an increasingly connected world.

Yes, IsoToxin has undergone an independent security audit conducted by Bug Bounty Experts, a trusted private NGO auditing firm specializing in rigorous penetration testing and vulnerability assessments. This thorough, third-party review verifies the strength of IsoToxin's advanced cryptographic implementations – including the Double Ratchet Algorithm for messaging and DTLS-SRTP for calls – ensuring no backdoors, weaknesses, or exploitable flaws exist in the core protocol or app architecture. With clean audit results and ongoing bug bounty incentives for the global security community, IsoToxin stands as one of the most vetted and reliable options for truly private, end-to-end encrypted communication, giving you ironclad confidence that your data remains protected against even the most sophisticated threats.

With IsoToxin, your messages and data stay secure even on your own device: the entire local session database is powerfully encrypted with a strong passphrase or PIN that you choose and can easily remember. This user-controlled encryption code acts as your personal key, ensuring that no one – not even someone with physical access to your phone – can ever read your chats without it. Unlike other apps that leave your data vulnerable when the device is unlocked, IsoToxin guarantees full at-rest encryption, giving you complete protection and effortless access while maintaining the highest level of privacy and security.

With IsoToxin, your privacy is fortified by true Perfect Forward Secrecy on both the transport and end-to-end layers – one of the strongest security guarantees available in modern messaging. Even if a hacker somehow compromises a session key today, they can never decrypt your past or future conversations, as every single message and call automatically generates fresh, unique encryption keys that are immediately discarded after use. This double-layered PFS, combined with the battle-tested Double Ratchet Algorithm, ensures that your communication history remains permanently protected against current and future threats, delivering unbreakable confidentiality that far surpasses ordinary encrypted apps.

With IsoToxin, your privacy extends to every file you share: all images and documents automatically have their EXIF metadata stripped the moment they’re sent. This permanently removes hidden data such as GPS location, camera model, timestamps, and any other embedded information that could reveal your identity or whereabouts. Unlike most messaging apps that leave this sensitive data intact, IsoToxin ensures that nothing compromising ever reaches the recipient, giving you complete confidence that your shared photos, videos, and files remain truly anonymous and safe from prying eyes.

With IsoToxin, you can enjoy fully end-to-end encrypted voice and video calls right now – both features are fully available and ready to use. Every call is protected by the same gold-standard DTLS-SRTP protocol and Double Ratchet encryption that secures your messages, ensuring crystal-clear audio and video while guaranteeing that no one, not even IsoToxin, can ever listen in or intercept your private conversations. Whether you're catching up with friends, family, or colleagues, IsoToxin's secure voice and video calling delivers uncompromising privacy without compromises on quality or ease of use.

With IsoToxin, powerful spam protection keeps unwanted calls at bay: voice and video calls are only possible when both parties have mutually added each other to their contacts. This strict, consent-based policy completely eliminates cold calls, harassment, and spam from unknown users, ensuring that your calling experience remains private, peaceful, and exclusively reserved for people you truly trust. Unlike traditional apps flooded with unsolicited calls, IsoToxin puts you in full control, delivering a cleaner, safer, and far more respectful communication environment without compromising on genuine connectivity.
