Mission

Privacy is the foundation of everything we do. To fight for our right to privacy – to protect journalists, whistleblowers and human rights activists as well as citizens around the world – this has been our mission since we have started building the encrypted email service Tutanota.

Join us in our mission to spread privacy via our community page.

We embrace full transparency and disclose mistakes openly and transparently. Security and transparency are closely interlinked and one cannot be achieved without the other.

We take our social responsibility seriously by running Tutanota completely on renewable energy and by offering the secure email service at a discount to NPOs and schools.

Team Spirit

√ Courage: We discuss conflicts, admit mistakes and propose ideas even if they may sound silly at first. We ask for help and offer help to each other if needed.

√ Responsibility: We decide on strategy, planning and design in teams. We incorporate pair programming.

√ Appreciation: We appreciate each other’s ideas and accomplishments.

√ Respect: We respect each other and their opinions.

Pine64
PinePhone

Pine64 is an organization which designs, manufactures and sells single-board computers, notebook computers and smartphones. While Pine64 is a legal for-profit entity, it operates much like a non-profit organization in the sense that it does not draw profits from most device sales, operates with volunteers, and reinvests income from sales back into the company. Its name was inspired from the mathematical constants pi and e with a reference to 64-bit computing power.

The Pine64 community is large, vibrant and diverse. Independent and partner-project developers, hackers and hardware enthusiasts, privacy advocates and FOSS geeks – you name it, we’ve got ’em all. They all contribute to the project thereby shaping it and determining its course. This page is community run, as is the Wiki, the chats as well as the forums.

Our goal is to push the envelope and deliver Arm and RISC-V devices that you want to use and develop for. To this end, we actively work with the development community and champion end-user initiatives. Rather than applying business to a FOSS setting, we allow FOSS principles to guide our business.

Proton ProtonMail

ProtonMail

End-to-End Encryption

Messages are encrypted and stored on ProtonMail servers at all times. They are also transmitted in encrypted format between our servers and user devices. Messages between ProtonMail users are also transmitted in encrypted form within our secure server network. Because data is encrypted at all steps, the risk of message interception is largely eliminated.

Zero Access to User Data

ProtonMail’s zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that we do not have access to. This means we don’t have the technical ability to decrypt your messages, and as a result, we are unable to hand your data over to third parties. With ProtonMail, privacy isn’t just a promise, it is mathematically ensured. For this reason, we are also unable to do data recovery. If you forget your password, we cannot recover your data.

Open Source Cryptography

We use only secure implementations of AES, RSA, along with OpenPGP. Furthermore, all of the cryptographic libraries we use are open source. By using open source libraries, we can guarantee that the encryption algorithms we are using do not have clandestinely built in back doors. ProtonMail’s open source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection.

Monero

Monero (XMR)

Monero is the leading cryptocurrency focused on private and censorship-resistant transactions.

The majority of existing cryptocurrencies, including Bitcoin and Ethereum, have transparent blockchains. Transactions can be verified and/or traced by anyone in the world. This means that the sending and receiving addresses of these transactions could potentially be linked to real-world identities.

Monero, on the other hand, uses various privacy-enhancing technologies to ensure the anonymity of its users.

Monero transactions are confidential and untraceable.

Unlike selectively transparent alternatives (e.g. Zcash), Monero is the only cryptocurrency where every user is anonymous by default. The sender, receiver, and amount of every single transaction are hidden through the use of three important technologies: Stealth Addresses, Ring Signatures, and RingCT.

Because every transaction is private, Monero cannot be traced. This makes it a true, fungible currency. Merchants and individuals accepting Monero do not need to worry about blacklisted or tainted coins.

Monero is electronic cash that allows fast, inexpensive payments to and from anywhere in the world.

With Monero, there are no wire transfer or check clearing fees, no multi-day holding periods, and no fraudulent chargebacks. Because Monero is decentralized, it is not constrained by any particular legal jurisdiction and provides safety from capital control.

Monero is a grassroots community attracting the world’s best cryptocurrency researchers and engineering talent.

The Monero Project is at the forefront of cryptocurrency privacy and security. Its Research Lab and Development Team are constantly working on new, innovative technologies. Since its launch, the project has received contributions from over 500 developers located all around the world.

Numerous forums and chat channels are available for anyone to join, and the community is always welcoming new members.

Whonix

Whonix

What is Whonix?

Whonix is software designed to preserve privacy and anonymity by helping users run applications anonymously. Whonix can be installed on Windows, macOS and Linux. Whonix also comes pre-installed in Qubes (Qubes-Whonix).

How does Whonix work?

To protect a user’s anonymity on the internet, all connections are forced through the Tor network and numerous security mechanisms are deployed.

What are the Advantages of Whonix?

Whonix realistically addresses common attack vectors.

An IP address is a label which is used to identify a computer on the Internet. A simple analogy is an IP address is similar to a car license plate.

Hiding IP addresses is technically difficult for software. There is always a risk of so-called IP leaks, whereby a user mistakenly thinks the IP address is hidden when it is actually not.

Whonix is the best solution to prevent IP leaks because it uses a more solid technical design. IP leak issues that previously applied to other software were not applicable to Whonix in a number of cases.

IP leaks are not the only issue that can break a user’s anonymity. Other threats include time attacks, keystroke deanonymization and data collection techniques. Whonix deploys numerous security mechanisms to mitigate such attacks.

How is Whonix different from a VPN?

Virtual Private Networks (VPNs) know your identity and online activity and can be compelled legally to share this information with authorities under various circumstances.

VPNs are usually faster than Tor, but they are not anonymity networks. VPN administrators can log both where a user is connecting from and the destination website, breaking anonymity in the process. Promises made by VPN operators are meaningless, since they cannot be verified. Tor provides anonymity by design rather than policy, making it impossible for a single point in the network to know both the origin and the destination of a connection. Anonymity by design provides much more security, since trust is removed from the equation.

Whonix isn’t a program like most of your applications. It’s a full operating system that runs inside your current one.

Defend yourself against tracking and surveillance. Circumvent censorship

Everyone should be able to explore the internet with privacy. The Tor Project is a 501(c)(3) US nonprofit. They advance human rights and defend your privacy online through free software and open networks.

Block Trackers

Tor Browser isolates each website you visit so third-party trackers and ads can’t follow you. Any cookies automatically clear when you’re done browsing. So will your browsing history.

Defend Against Surveillance

Tor Browser prevents someone watching your connection from knowing what websites you visit. All anyone monitoring your browsing habits can see is that you’re using Tor.

Resist Fingerprinting

Tor Browser aims to make all users look the same, making it difficult for you to be fingerprinted based on your browser and device information.

Multi-Layered Encryption

Your traffic is relayed and encrypted three times as it passes over the Tor network. The network is comprised of thousands of volunteer-run servers known as Tor relays.

Browse Freely

With Tor Browser, you are free to access sites your home network may have blocked.
