No. PGP (Pretty Good Privacy) is an asymmetric encryption protocol developed in 1991 by Philip R. Zimmermann. It was originally designed for securing email communications rather than real-time messaging. While PGP remains a strong and widely respected encryption standard, it does not provide forward secrecy or perfect secrecy. Additionally, it lacks features such as plausible deniability, and if a private key is ever compromised, previously encrypted messages may be decrypted.

CryptoChat uses modern, state-of-the-art cryptographic primitives to ensure secure communication. Messages are encrypted using XChaCha20-Poly1305, an authenticated encryption scheme that provides both confidentiality and integrity with a 256-bit key. For key exchange, CryptoChat utilizes Curve25519 (X25519) ECDH alongside SNTRUP761, a post-quantum key encapsulation mechanism, in a hybrid approach designed to offer strong security against both classical and potential future quantum attacks. This combination of well-established and forward-looking cryptographic techniques is widely regarded as highly secure and suitable for modern high level secure messaging systems.

Multi-hop routing is a privacy-enhancing technique where messages are relayed through multiple independent relays before reaching their final destination. In CryptoChat’s implementation, messages pass through a triple-hop relay system, meaning they traverse three separate servers along the way.

This design ensures that no single server has full knowledge of both the sender and the recipient. Each relay only knows the immediate node it received the message from and the next node it forwards it to, but never the complete path. As a result, it becomes extremely difficult to correlate who is communicating with whom.

Combined with the fact that we do not maintain user identifiers or logs, this architecture prevents us or any intermediary from linking messages to specific users. Even in theory, a single point of observation cannot reconstruct the full communication path, providing the strongest level of anonymity and protection possible.

No. CryptoChat is designed with multiple safeguards to prevent unauthorized manipulation. Updates cannot be delivered to user devices unless they are verified through a strict multi-signature process, requiring approval from multiple trusted members of our team. Any attempt by an adversary to distribute a malicious or unauthorized update would be automatically rejected by the device.

Additionally, even in the unlikely event that a server were compromised, it would not expose user data. Our servers operate solely as relay nodes and do not store sensitive information. All data passing through them is end-to-end encrypted, meaning it remains unreadable and inaccessible to the server itself or any third party.

No. We do not have access to or store any information related to our clients’ chat accounts, contacts, encryption keys, passwords, messages, notes, or other personal data. The only information we retain is whether a CCID remains valid until the end of the subscription period. Even this data is not linked to any chat or eSIM details. As a result, we are unable to provide such information because we simply do not possess it. All messages are end-to-end encrypted and all encryption keys never leave a device.

No. As stated in previous responses, we do not have access to any client information and we do not maintain logs. Even if we intended to do so, it is technically impossible for us to access or retrieve such data.

CryptoChat operates its own Mobile Device Management (MDM) software to effectively manage and secure all encrypted handsets. Our MDM solution is fully developed in-house, allowing us to maintain complete control over its functionality, security standards, and data handling processes.

By not relying on any third-party providers, we ensure a higher level of privacy, flexibility, and customization tailored specifically to our operational needs. This approach also enables us to respond quickly to security challenges, implement updates efficiently and securely, and continuously improve our system in line with evolving industry standards.

CryptoChat exclusively uses its own in-house developed Mobile Device Management (MDM) system to manage Android secure device policies. This dedicated solution allows us to enforce strict security configurations and maintain full control over device management processes.

Our MDM system ensures that all devices running CryptoChat consistently meet our security standards and compliance requirements. By managing everything internally, we can rapidly implement security updates, address potential vulnerabilities, and adapt our policies to meet evolving security demands.

CryptoChat features a custom designed secure networking architecture built to protect user privacy at a deeper level. Rather than relying on traditional VPN solutions or any 3th party VPN providers, we have developed our own multi-relay hop system to enhance both security and anonymity.

This approach routes communication through multiple layers, reducing the risk of tracking or interception and providing stronger protection against network-level threats. While VPNs can offer a basic layer of privacy, they are not sufficient on their own to ensure true security.

At CryptoChat, we emphasize end-to-end encryption combined with advanced network anonymization techniques, ensuring that user conversations remain private, secure, and resilient against evolving threats.

No, this practice does not provide any meaningful security benefit and is highly unintuitive for most users.

When you change an IMEI, often referred to as “flashing,” it is essential to also replace your SIM card before reconnecting to a mobile network. If you do not, the telecom provider may associate your new IMEI with your previous IMSI, effectively linking the two and undermining the intended purpose of changing the device identifier.

To achieve a higher level of privacy, all connections would need to be disabled, the SIM card replaced, and the IMEI changed before reconnecting to a network. Even then, this approach remains complex, impractical, and in many jurisdictions, illegal.

Any service claiming to offer instant IMEI changes without requiring a reboot or at least a noticeable interruption in network connectivity is misleading and should not be trusted.

Legitimate modification of device identifiers involves low-level system changes that cannot occur seamlessly while the device remains fully connected to a network. Claims suggesting otherwise are often indicative of ineffective or fraudulent solutions that fail to deliver real functionality or security benefits.

Users should exercise caution and avoid relying on such services, as they may provide a false sense of security and potentially expose devices to additional risks.

CryptoChat standardizes on Google Pixel devices due to their advanced hardware security capabilities. These devices incorporate the Titan M2 security chip, which supports features such as verified boot, hardware-backed key storage, and enhanced protection against physical tampering.

Google Pixel devices also offer timely security updates and clearly defined support lifecycles, which are critical for maintaining a secure and compliant environment. In addition, the Pixel platform provides the flexibility required to deploy and maintain our custom operating system in a controlled and reliable manner.

This combination of hardware security, software integrity, and long-term support aligns with CryptoChat’s requirements for delivering a secure and trustworthy communication platform.

CryptoChat supports devices only for as long as they continue to receive official security updates from the manufacturer. Once these updates are discontinued, we can no longer ensure that the device meets our security standards. As a result, support for that model is also discontinued to maintain the highest level of security for our users.

No. CryptoChat, along with all authorized resellers, only provides brand-new devices that have never been used before. This ensures the integrity, security, and reliability of the hardware from the outset.

Battery life depends largely on the device model you choose. Older or entry-level models typically offer around two days of usage on a single charge, while higher-end models can provide approximately three to four days of battery life under average usage conditions. Actual performance may vary based on usage patterns and settings.

Your network connection may be slow if you are in an area with poor signal strength or limited to a 2G network. Performance can also be affected by temporary network outages or if you are outside the coverage area of CryptoChat cellular network.

In such cases, reduced speeds, higher latency, or intermittent connectivity may occur. For the best experience, we recommend using CryptoChat in areas with strong network coverage and a stable connection.
