Store description excerpt
MAX App is free to download and lets you protect data, sign documents, and use a personal digital identity without creating an account. No required email. No phone number. No profile to register before getting started. MAX is based on a simple idea: privacy should not depend on a central account, a password that someone else can recover, or a server that stores everything for you. With MAX App, your digital identity is designed to stay under your control, together with the data you choose to protect, sign, or store. MAX App includes several tools in a single experience: MAX Vault A local vault for storing texts, notes, and important information directly on your device. MAX Signature A tool for signing digital content and documents, helping you prove the integrity and authenticity of signed data. MAX Login A personal identity system based on QR codes, passwords, and digital signatures, without traditional accounts, email, or phone number. MAX Chat An encrypted chat designed to protect message content. MAX Prime An experimental module dedicated to mathematics, prime number research, and the exploration of repeatable results. Mathematical verification Tools to check, compare, and analyze results generated by the app in a transparent way. The technology behind MAX MAX App is built around a simple principle: protecting data, identities, and signatures directly on the user’s device, without creating accounts. It combines a local vault, a personal identity system, digital signatures, encrypted chat, and verification tools in a single experience. Sensitive operations happen locally and use modern cryptography, key derivation, authenticated encryption, digital signatures, and post-quantum components such as SPHINCS+ and FrodoKEM. MAX is not designed to store your secrets for you, recover them remotely, or replace user control with a central server. It is designed to reduce what needs to be shared, avoid traditional accounts, require no email or phone number, and give you more control over what you protect, sign, and store. MAX App is free to download, and the main modules remain usable without mandatory purchases. MAX Premium is an optional one-time purchase that adds advanced features and extra convenience for MAX Vault and MAX Signature. The main modules remain available for free. MAX App does not promise absolute security, but offers a concrete approach: privacy, identity, and protection in a single app, with more local control and without accounts, email, or phone number.
