Why We Don't
Our philosophy, in plain language.
Why we don't use subscriptions
Subscriptions create a relationship where the company needs you to keep paying, not necessarily to keep improving. We think that's backwards.
Fonszi apps use a one-time purchase model. You pay once, you own it forever, including all future updates. No renewals, no "your trial has expired" pop-ups, no anxiety about another monthly charge.
We make money when we build something worth buying. If we stop earning your trust, we stop earning your money. That's the deal, and we think it's a fair one.
Why we don't track you
We use Umami for website analytics. It's open-source, cookie-free, and collects zero personal data. No fingerprinting, no cross-site tracking, no advertising IDs. We can see that someone visited a page. We cannot see who.
Our mobile apps use Firebase Analytics with minimal, anonymous event tracking. No email addresses, no device IDs tied to profiles, no data sold to third parties. We track what features are used so we can make them better, not so we can target you with ads.
There is no cookie banner on this site because there are no cookies to consent to.
Why we don't use cloud backends
Your ski sessions, your workout data, your design files, your code analysis results: they stay on your device. Fonszi apps are local-first. They work offline, they sync nothing to our servers, and they cannot be held hostage by an outage or a shutdown.
If Fonszi disappeared tomorrow, your data would still be right where you left it: on your phone, on your laptop, in your hands.
Where a server is needed (authentication, license validation), we run our own infrastructure. No third-party SaaS middlemen sitting between your data and you.
Why we open-source our tools
Several Fonszi developer tools are open-source: git-hook-suite, our shared libraries, and the infrastructure we build on. If you can read the code, you don't have to trust our claims. You can verify them.
Open source means bugs get found faster, contributions make the tools better for everyone, and the community can adapt our work to their own needs. It also means that if we ever fail to maintain something, someone else can pick it up.
Transparency is not a marketing strategy. It's how software should be built.
