A One-Person Mission to Redefine Private Messaging
In an age of hyper-connectivity and mass data collection, Conversations is a quiet rebellion. It was built not by a company with hundreds of developers but by one dedicated individual: Daniel Gultsch. Daniel Gultsch, the sole mind behind Conversations, spent over a decade developing a privacy-first, open-source messaging app that puts users, not corporations, in control.
Conversations began as a personal project out of Daniel’s desire for a secure, lightweight, self-hosted messaging tool. Today, it’s used by hundreds of thousands of people, from individual privacy advocates to organizations in sensitive fields such as healthcare, who want full control over their communications without sacrificing usability.
Messaging Without Surveillance
Unlike most chat apps, Conversations doesn’t track user behavior or store personal data. There’s no account required, no analytics running in the background, and no data flowing to central servers. Users can run the app on their own infrastructure, keeping everything from chat logs to server preferences under their control.
The app is also fully open source, meaning anyone can inspect the code and verify how it works. This level of transparency builds trust and demonstrates that Conversations has nothing to hide—a rare stance in today’s mobile software landscape.
While Conversations is available through mainstream channels like Google Play, it’s also distributed via F-Droid, a free, open-source app store. Daniel publishes a minimalist privacy policy: “We don’t want your data, and we don’t collect it.” This simplicity and honesty is reflected in every aspect of the app.

Community-Driven and User-Focused
Although Daniel develops the app alone, Conversations is powered by a global community of users who contribute ideas, report issues, and help determine development priorities. From GitHub to Telegram and in-person exchanges at tech conferences, Daniel actively listens to feedback. At the same time, he remains focused on designing for the silent majority—the 99% of users who never write in, yet rely on the app daily.
Over the years, this grassroots engagement has helped Conversations grow steadily despite the lack of formal marketing or business development. It’s proof that an ethical, well-built tool can succeed on merit alone.
Lightweight, efficient, and built to last.
Beyond privacy, Conversations also champions technical sustainability. It’s optimized to run on older Android versions, helping users avoid premature device upgrades and e-waste. The app is lightweight and efficient, minimizing battery usage and extending the life of both hardware and software.
Daniel considers these technical choices to be part of the project’s overall ethical approach. With no dependency on cloud computing and low data usage, Conversations reduces energy consumption while keeping users digitally self-sufficient without compromising performance.

Always Evolving, Never Compromising
Conversations continues to evolve in step with users’ changing expectations. Daniel’s to-do list is long—from refining message replies to incorporating modern features like reactions—but all updates are guided by a deep respect for simplicity, privacy, and user control.
At the same time, he faces the challenges of being a solo developer. One limitation he acknowledges is the lack of metrics. Without user data, it’s difficult to track active installations or monitor performance across servers. Still, he sees this as a fair trade-off. Privacy comes first.
Advice for Ethical Tech Builders:
For startups and developers entering the ethical tech space, Daniel’s advice is straightforward: Build something you personally want to use. When he started developing Conversations, it was his main messaging tool, so every bug affected him directly. He believes that level of personal involvement is what drives true quality.
He also cautions against chasing funding too early. Instead of seeking investors, he started with passion and purpose—and that’s what has sustained Conversations for over a decade.
Conversations proves that building secure, sustainable, and ethical technology doesn’t require a large team or significant funding. It does, however, require clarity of purpose, transparency, and the courage to put users—not data—at the center.
