Human Rights Declaration

You have a right to privacy.

Privacy is a human right. Everyone knows what privacy feels like — it feels comfortable, safe, and secure. When we are in private, we have the freedom to share ideas and be ourselves. In the physical world, we all take steps to protect our privacy every day. But privacy has fallen by the wayside in the digital world. If we want the internet to be a free, fair, and equal place for everyone, we must design, create, and share technology which preserves people’s privacy and enables them to experience the internet in a safe and secure way.

OPTF’s mission is to equip every digital citizen with technology which upholds their right to privacy. Whether you’re buying a coffee, messaging a friend, or simply browsing the internet, your privacy should always be protected. It shouldn’t have any strings attached — it should be provided by default, and it should be free.

One of the OPTF’s main development achievements is the private messenger, Session. Session is a free and open-source application which allows people to have completely private, secure, and anonymous conversations online. Session is a tool for protecting free speech including for journalists, activists, and other people working in civil society.

We are actively implementing technology projects that help us achieve our mission. These projects include:

Our guiding principles are to:

Build open-source, secure communications tools that are free and accessible.

Produce educational resources to support people and organisations to better understand, use, and implement privacy technologies.

Complete work which serves the interests of the public. Our work helps foster an open, accountable, and unified digital community.

Collaborate with other organisations on work which upholds digital rights.

Support, fund, and assist projects that align with our principles.
