Aligned by Design: Why Food & Trees for Africa Chose Signal Messenger

In the modern non-profit sector, the digital tools we rely on are just as vital as the seeds we plant and the communities we uplift. At Food & Trees for Africa (FTFA), we coordinate complex, multi-layered operations across vast geographical areas. From organising logistics for large-scale tree planting to managing decentralised agricultural programmes and communicating with field staff, our operations require a messaging platform that is fast, reliable and secure.

Yet, beyond pure functionality, around five years ago we confronted a more profound question: Do the digital tools we use every day reflect the ethical standards we hold ourselves to?

When evaluating our internal and external communications infrastructure, the answer became clear. We needed a platform that didn't just serve our logistical needs, but one that actively aligned with our core values. This is why Food & Trees for Africa officially adopted Signal Messenger as our primary messaging platform.

The decision goes far beyond technical features; it is rooted in a shared ethos, a commitment to transparency and the fundamental belief that non-profits must support non-profits. However, ethics alone (including digital ethics) do not run operations. Five years into this transition, we remain incredibly happy with the day-to-day performance and functionality of the application.

The Ethos: Non-Profits Supporting Non-Profits

The non-profit ecosystem thrives on collobration and solidarity. As an organisation dedicated to addressing food security, environmental sustainability and climate change, we operate in a space driven by purpose rather than profit. It is a fundamental ethical imperative that we extend this philosophy to the vendors and platforms we rely on to do our work.

Most modern communication platforms are owned by massive, publicly traded tech conglomerates. Their underlying business models are inherently extractive: designed to maximise shareholder value, often through the monetisation of user data and attention. For a non-profit, relying on these platforms creates a subtle but persistent friction between our mission and our operational footprint.

Signal, however, is an anomaly in the tech world. It is developed by the Signal Technology Foundation, an independent 501(c)(3) non-profit organisation. By choosing Signal, FTFA is actively participating in an ecosystem of mutual support. We are choosing to back an organisation that, like us, exists solely to serve a public good. Signal is not beholden to investors, board members seeking financial returns or advertisers. Its sole metric of success is fulfilling its mission to protect free expression and enable secure global communication.

When non-profits support non-profits, we create a parallel economy based on shared values and collective well-being rather than exploitation.

Transparency as a Core Ethical Pillar

At Food & Trees for Africa, transparency is the bedrock of our operations. Whether we are reporting to institutional donors, collaborating with corporate partners or working alongside community leaders on the ground, we believe that open, honest communication is the only way to build lasting trust. We hold ourselves accountable for every tree planted and every food growing project established.

We expect the same level of accountability from our technology. Signal stands completely apart from its competitors through its radical commitment to transparency. The entire Signal application, from its underlying cryptographic protocols to its client software, is completely open-source. This means its code is available for anyone in the world to review, audit and verify.

In a digital age where "black box" algorithms and hidden data-harvesting practices are the norm, Signal’s open-source nature is a breath of fresh air. They do not ask us to blindly trust that our data is safe; they prove it by operating in the light. This architectural transparency perfectly mirrors FTFA's organisational transparency. We believe that what happens behind the scenes is just as important as the outward-facing work, and with Signal, there are no hidden agendas.

A Platform Powered by Passion and Community

A common misconception in the software world is that non-profit or open-source tools lack the polish, speed or reliability of corporate products. Signal shatters this myth entirely. Half a decade into relying on it for our most critical communications, we can attest that it is a world-class, incredibly secure and beautifully functioning platform. But why does it work so well?

The answer lies in community. Signal is maintained by a relatively small but fiercely dedicated group of developers, cryptographers and privacy advocates. Because they are not pressured to build "sticky" features designed to increase screen time or harvest metadata, they can focus 100% of their energy on building a clean, efficient and highly secure communication tool.

This resonates deeply with our work at FTFA. We know first-hand that the most successful, sustainable projects are not those imposed from the top down, but those driven by passionate, engaged communities. Just as our community food gardens flourish because of the dedicated ecopreneurs and local farmers tending to them, Signal functions exceptionally well because of the passionate community safeguarding its code. It is technology built with care for the people who use it.

Data Sovereignty and Respecting the Communities We Serve

Finally, the shift to Signal is a profound statement about how we view privacy and data sovereignty. In the course of our work, we communicate sensitive information, ranging from logistical planning to the personal details of the vulnerable communities and individuals we partner with.

Mainstream messaging apps routinely collect vast amounts of metadata: who you are talking to, when, from where and how often. Signal is explicitly designed to collect as little data as possible. Because of its state-of-the-art end-to-end encryption (the open-source Signal Protocol), not even Signal itself can read our messages or listen to our calls. Think about this in the context of us assessing hundreds of Early Childhood Development (ECD) centres in vunerable communities around the country - often sending GPS pins and multiple photo's.

By using Signal, FTFA is making a deliberate choice to protect the digital autonomy of our staff, our contractors and our beneficiaries. We refuse to feed the surveillance machine with the operational data of our humanitarian and environmental work. We respect our ecosystem too much to subject their communications to corporate data mining.

Conclusion

The tools an organisation chooses to use are an extension of its ethics. For Food & Trees for Africa, the medium is part of the message. By adopting Signal Messenger as our official platform, we have aligned our digital infrastructure with our physical mission.

We are proud to support a fellow non-profit, to champion transparency and open-source collaboration and to fiercely protect the privacy of our network. Most importantly, we have proven that choosing an ethical platform does not mean compromising on quality. As the non-profit sector continues to navigate an increasingly complex digital landscape, we urge other organisations to look closely at the tools they use. When we align our technology with our values, we don't just communicate more securely; we communicate with integrity.
