about

I run my own infrastructure. Not because it’s easier — because it’s mine.

Dedicated server at home, VPS in Iceland, WireGuard tunnel between them. Custom Flask backend, nginx in front of everything, XMPP server for comms. Every request goes through hardware I control.

Privacy isn’t a feature. It’s the architecture.

Everything here runs on hardware I own and pay for, reverse-proxied through a bulletproof edge in a privacy-friendly jurisdiction so the origin IP is never exposed. No managed hosting, no data sharing, no ads. Running costs are power, colocation, server rent, domains, SSL and upkeep. If you want to help keep it online — every bit goes straight into the box. Thanks.
