Protect your calls & messages



Arenim Technologies designed the CryptTalk service to provide the same user experience and feature set you're used to when making traditional calls. Make mobile voice calls and compose instant messages just as with Skype, WhatsApp or Viber. However...



CryptTalk provides
maximum security.






Protect your privacy

Unlimited secure calls

All subscriptions include unlimited secure calls over your mobile internet network or Wi-Fi. There are no per-minute charges.

Unlimited secure messages

Send as many secure CryptTalk messages as you like. They are free. Don't risk losing your privacy.

Secure
conference calls

Organize secure conference calls with several participants. CryptTalk conference calls are peer-to-peer, mixed on your handset without the involvement of a central conference server, which maximizes your security.

Get connected,
get secured quickly!

CryptTalk is independent of your device or phone number. It is linked to your e-mail address.
Build your CryptTalk contact list. Invite others to connect with you with a simple e-mail.

Pay as you go
No long-term commitment


As an Individual User you have a wide choice of monthly subscription packages based on the number of persons you want on your CryptTalk contact list.
