About us

When great ideas meet beautiful craftsmanship, it changes the world.

We pour this simple philosophy into every job that we do, and every project that we support. With ideals firmly rooted in open source software, and a desire to give back to the global community, Cypher Stack engages customers of all types and from all walks of life, so that we can change the world together.

We believe in open source

Cypher Stack has been heavily involved in the visual aspects - such as web and app design - and their subsequent implementations of various open source projects, such as Monero, Kovri, and Monerujo. We believe open source empowers people, and is the future of technology.

We support cryptocurrencies

Our commitment to serving clients from all over the world mixed with a healthy sprinkle of cypherpunk values has led us to accept cryptocurrencies for our goods and services. The current list of accepted cryptocurrencies is below in order of preference.

Monero Bitcoin Litecoin

We practice ethical design

Many websites are designed to track you, sell your information, or to keep you on the site. We are committed to honor your privacy, which we accomplish by forgoing Google Analytics and instead using Matomo, an open-source, self-hosted site analytics system that honors Do Not Track (DNT) requests, and anonymizes IP addresses by country. Our site also uses little javascript, so you can keep tabs on what's running on your machine.

Linguist and translator by training, Maria could not resist her instinct to make the world accessible and pretty. She is a hopeless perfectionist (to the delight of our clients). Hobbies include drawing, lifting, and listening to Diego's rants about open source and privacy.
