Post-Quantum Cryptography (PQ-ECC)
The future of data protection is here. With Ciphr Lite, your message & call data is already protected from future quantum attacks with PQ-ECC.
More than just end-to-end encryption
Next-level privacy means the strongest end-to-end encryption and powerful protection for data at rest.

User-Controlled Keys

Private encryption keys are generated and stored locally on the device hosting your Ciphr Lite app. Only you have access to your private keys, so only you have access to your data.

Perfect Forward Secrecy

Each message and call is encrypted with a unique encryption key for a deeper level of protection in your chat conversations.

Password Protected

Password protection encrypts the data stored in your Ciphr Lite app with AES-256 encryption, while Argon2 protects passwords from password guessing attacks.
Full of
security-first features

Anonymous Ciphr ID (CID)

Ciphr Lite accounts don’t require an email or phone number to register, and generate a randomized Ciphr ID (CID) for contact identification.

Self-destructing messages

All messages in Ciphr Lite will self-destruct after a set time. This privacy feature is particularly useful if you share sensitive data like passwords, financial details or personal identification information.

Redact sent messages

Stay in control of your messages even after you’ve sent them with the ability to delete previously sent messages so that anyone in the chat can no longer view them.

Encrypted voice notes

More to say but no time for a call? Send encrypted voice notes to bring your chats to life.

Encrypted image sharing

Share images using the same encryption used to protect your message and call data.


Can I communicate with a Ciphr Text user with Ciphr Lite?

Is Ciphr Lite available on iPhone?

Yes! Ciphr Lite iOS beta is currently available, with Ciphr Lite being available in the Apple App Store in Fall 2021.

Do I need to register a name, phone number, or email to activate a Ciphr Lite account?

No! You do not need to provide Ciphr with a name, phone number, or email to activate your Ciphr Lite account.

Why? We believe that you should own and control your data. Without Ciphr having these details, you can have confidence that Ciphr does everything to put your privacy first.

What's the difference between Ciphr Lite and Ciphr Text?

Ciphr Lite and Ciphr Text are both world-leading end-to-end encrypted messaging and calling apps. Both apps protect your communication data with PQ-ECC and AES-256 encryption. However, Ciphr Lite is limited by communication restrictions and removed features which are only available in Ciphr Text.

Although there are differences in the available features for each version, both Ciphr Lite and Ciphr Text users can communicate with the most powerful encryption and security features available.
