CTemplar is a secure, encrypted email service that has stayed below my radar until very recently and in my first few days of testing it, stands up there with the likes of Protonmail and Tutanota. Its first stand out plus point is that it is based in Iceland which has some of the strictest privacy laws in the world and cannot be seen by what CTemplar claims are the 14 Eyes nations. Iceland also has a no data retention policy so when you press ‘delete’ your data is deleted, unlike most countries that have data retention laws requiring at least six months before emails can be permanently deleted. When you hit “delete” it is gone for good.
CTempar is independently owned and funded, and its code is available under a permissive open-source license. The grants and investment proposals often seen from governments and corporations have always been aimed to invade its users’ privacy and it deliberately rejects all government and corporate investments and grants.
The service uses the OpenPGP.js library, maintained by Proton Technologies AG, which is trusted by hundreds of people, corporations, and governments. This library receives endless audits from professionals and users alike.
CTemplar uses Zero-Knowledge Password Protection technology, so it does not know the password for your private keys, and it is not capable of accessing your encrypted data by any means.
We employ SRI to safeguard our users from malicious scripts, which makes CTemplar resistant to Man-in-the-Middle attacks and ensures that no harmful script can be served from our server.
The company states: “We employ SRI to safeguard our users from malicious scripts, which makes CTemplar resistant to Man-in-the-Middle attacks and ensures that no harmful script can be served from our server.” Also “Your IP address is stripped from logs and metadata and We do not know your IP, and we use CTemplar’s IP for all emails. Additionally, mailboxes aren’t linked to IP addresses in any way.”
There is a wider range of subscription prices ranging from free to $50 a month with additional features added accordingly.
Currently, CTemplar is available via a web browser or IoS and Android apps. Mac, Linux and Windows are planned.
