Support our mission

Illustration of the PrivacySafe sundial above the words Support our mission: advancing privacy, education, FLOSS, decentralized technology, and public-interest research, with two people working at night above a row of icons for education, FLOSS, decentralized technology, research, and community.

100% reaches the mission. We fundraise with Zeffy, which charges the Foundation no platform fee, so every dollar of your donation goes to our work rather than to payment processing.

Ways to give

PrivacySafe Bot

PrivacySafe Bot, our free password and passphrase generator, is one of the teaching tools we build and give away. It runs in the browser and estimates keyspace in bits so learners can see why length beats cleverness.

Ways to give.

We believe strong privacy and security should be available to everyone. Your support builds the tools, resources, and learning opportunities that make a safer digital life possible — and gets you early access to our educational materials and to privacy and cybersecurity software as it takes shape. Pick whichever route suits you; they all fund the same work.

Projects under the Foundation umbrella

Four public-interest projects the Foundation stewards. All of them are free to use, and the code behind them is Free/Libre and Open Source Software.

Cybersecurity Education

“Take Back Your Bytes” is PrivacySafe Foundation's cybersecurity education campaign for K–12 schools, higher education, and online learning communities.

The campaign provides educational materials, lesson plans, demonstrations, and tools that help learners understand privacy, secure communication, digital identity, cryptography, and responsible technology use.

Public-interest tooling ships as readable repositories: signing, verification, and publishing scripts anyone can audit.

Standards & Protocols

The Foundation supports open standards and protocol documentation, including the 3NWeb Protocols hosted at IEEE SA Open. These specifications support self-sovereign identity, zero-knowledge design patterns, secure data systems, and interoperable privacy-preserving infrastructure.

Our libraries and reference implementations are Free/Libre and Open Source Software, so anyone can read them, run them, teach from them, and build on them.

What We Do

Our focus is upstream: education, documentation, public-interest tooling, security research, and global collaboration.

K–12 Schools

Age-appropriate lessons and activities that introduce privacy, cybersecurity, digital safety, responsible technology use, and data protection basics.

Higher Education

Educational materials for colleges, universities, and professional programs focused on AI, cryptography, decentralized networks, and blockchain-based systems.

FLOSS Libraries

Reusable Free/Libre and Open Source Software components that support privacy-first development, secure software education, and public learning.

Security

Technical analysis, testing, and documentation that improves trust, resilience, and practical understanding of secure systems.

Interoperability

Open protocols and data formats so people can move between services, federate with others, and avoid being locked into a single vendor.

Community

Our projects are supported by developers, researchers, educators, and security experts around the world. Publishing in the open means the software benefits from continuous outside testing, review, and analysis — which is the whole argument for doing it this way.

About the Foundation

PrivacySafe Foundation, Inc. is a 501(c)(3) nonprofit public charity based in Connecticut, USA, with contributors spanning four continents. Our work is upstream and non-commercial: we teach, document, research, and release code.

The software and who sells it

The PrivacySafe applications — encrypted chat, calls, and storage — live at privacysafe.app. The Foundation stewards the upstream work: the 3NWeb protocols, the filesystem, reference implementations, documentation, and the educational material built on top of them.

Selling is a separate job, done by a separate company. Ivy Cyber LLC in the USA is the commercial publisher of PrivacySafe-brand products and services, working with its international partners 3NSoft in Canada and Kuip Limited in the European Union. That split is deliberate: it keeps the nonprofit free to teach, publish, and give things away.

So there are two ways to put money behind this work, and they do different things. A donation funds the Foundation's teaching, research, and public code. Buying a product or a support contract from Ivy Cyber pays for the software you run.
