Bulletproof privacy

When PGP encryption was first introduced, it offered complete security, but there was a catch: only geeks could use it.

Then came encryption services, making it possible for everyone to send encrypted emails. However, this introduced a new problem: users were no longer in control; the companies providing the encryption were. 

That’s why we, at Privacy Everywhere, created Arca—the first easy-to-use, fully secure email client that puts control back in the hands of the users. 

Decentralized architecture

“Secure” email services store your emails and private key on their server, meaning they can potentially access your private emails. 

Privacy Everywhere doesn’t provide an email service, therefore we don’t have any of your emails, nor your private keys. We are simply providing a tool: Arca. You can use any email service of your choice, and your private key is stored on your device only. 

Email Privacy is back and in its natural decentralized form.

Vivarto grew up in the Soviet Union and later moved to the West, where he witnessed the gradual creep of surveillance and censorship. Determined to find a private way to communicate, he discovered that none of the existing solutions met his needs. So, he created Arca.

FAQ

We are in an advanced beta stage.
No, Arca works with all modern email providers including Gmail, Yahoo, Outlook etc.
Our code is available for peer review upon request
Emails sent through Arca are secure in transport. Additionally emails are password protected on the user’s computer. Arca uses a standard encryption algorithm the same as governments & military
ProtonMail has your private keys, Arca does not.
ProtonMail‘s protection against a Man-in-the-Middle Attack is extremely difficult to implement, Arca’s is easy.
With ProtonMail you can only have a johnsmith@protonmail.com account. With Arca, you secure your existing accounts, i.e. johnsmith@gmail.com.
You can use Arca with an unlimited number of accounts.
Arca’s digital signatures can authenticate any document or file, not just emails.
Our basic email security software is free of charge

Yes, Arca PE’s encryption is compatible with all software using PGP/MIME (and PGP/Inline) standard.

Secure Mail means your emails are fully secure in transport and at rest. However, the security of your emails could be hacked by exploiting your computer directly. This can be prevented by having an extremely strong password.

ProtonMail and other “secure email” services are examples of centralized email solutions: if an attacker breaches their servers, they gain access to both the emails and the private keys. In contrast, a well-designed email client is decentralized, utilizing any email service while ensuring the private key remains solely on the user’s device without their permission.

Even if an attacker breaches these servers, they cannot read the emails, as they lack access to the private keys, which are securely stored on the user’s own devices (computers, phones, etc.).

Arca is an email client, not an email service. Many easy to use encryption services exist (i.e. ProtonMail, Tutanota). The problem with these services is they lack real security. Arca is the first easy to use and fully secure email.
Secure Drive is a virtual drive. It can be instantly open or closed. The data inside this drive is encrypted with AES256, which is the unbreakable standard which is used by governments and military. On Windows, this is installed with the installation of Arca and it instantly works. However, on macOS, the installation requires a little technical skill. It can only be installed if the user has already installed macFUSE.
