Quantum resistant end-to-end encryption for all modes of communications - conferencing, voice, video calls, messaging, file transfer. Today's encryption--whether you use them for communications, banking, or other apps--are safe with today's computing power. Quantum computers, which are in development, are so powerful and fast that they can break current encryption technology. Quantum Resistant Encryption, by Quanta, deploys a NIST (National Institute of Technology and Standards) methodology to protect all your communications--an industry first! Quantum Resistant Encryption (QRE™) - QRE™ makes our communications modes unbreakable by quantum computers that will break all current encryption algorithms. All your communications are protected today against future threats from next-generation quantum computing. Built for Zero Trust - Use Quanta with contacts you trust and invite or who invite you. Quanta disallows random calls. Have confidence in the identity of the other participants. No Communication Content on Servers - Messages are stored only on the endpoint devices of the users, never on our servers. We collect no information about users except login credentials and payment method. Clean and functional user experience. No Storage of PII - Our privacy policy is the best in the industry. We do not collect personally identifiable information (PII). We use no cookies. We do not sell or share your information. Hosted in the U.S.A. - Our competitors won't tell you where their servers are located. We do. Not subject to the policies and practices of jurisdictions of other countries. Independent of Big Tech - We host with independent American data centers and are not subject to the policies and politics of Microsoft, Google, Apple, or AWS. No risk of being shut down. Disappearing Messages - Each sender controls the 'time-to-burn' for the messages they send. Senders can 'burn' the message on each side once it has been read. Sender controls if and when messages expire on recipients' devices for ultimate privacy. Secure File Transfer - Transfer files up to 100 MB encrypted with QRE throughout our messaging platform. Important documents are protected with QRE like all other communications and cannot be read if intercepted. End-to-End Encryption - All communication modes—messaging, voice, video, and group calls—are end-to-end encrypted versus point-to-point encryption that requires a decrypt-encrypt step at some point in the communication delivery. Not so with Quanta. Complete privacy and confidentiality. Zero risk that content may be hacked or leaked. Platform Independant Subscription Based - Quanta is great for families, small and large businesses, and organizations. Our pricing is simple, affordable, and easy to manage. You pay for our service, so your information is not for sale. Direct Person-to-Person Calls - Calls from one person to another are device-to-device and do not pass through servers. With end-to-end QRE, this is the ultimate in communication security. No chance of calls being intercepted.
