Who
lans.cloud is built and run by Sonny Lans, an independent software developer in the Netherlands. There is no company behind it, no growth team, and no investor asking for engagement metrics — just one person who builds tools, and the people who use them and ask for improvements through the feedback button at the bottom of every page.
Why
The site started with a specific moment: a teacher projects a countdown timer for a classroom activity, and a banner ad flashes next to it in front of thirty children. Every free classroom tool seemed to accept that as normal. This site doesn't — every presentation-style tool here has a one-click fullscreen mode with zero ads, and that will not change. Ads exist on the regular pages, clearly separated from the tools, because hosting costs money and the tools are free; they never interrupt a tool and never appear on a projected screen.
How the tools work (and why that matters)
Every tool computes entirely in your browser. Class lists, word lists, seating rules, participant names for a secret santa draw— none of it is transmitted anywhere, because the site has no server code that could receive it. What you type is stored, at most, in your own browser's local storage so it's there when you come back. The noise meter is the clearest example: it reduces microphone input to a single number on your device and discards the audio. The only things the server ever counts are anonymous page views.
The promises, in one list
- Fullscreen presentation modes never show ads. Ever.
- No accounts, no sign-ups, no email collection.
- Your data stays in your browser — there is nowhere else for it to go.
- Every tool is free, with no premium tier holding features back.
- Feedback gets read by the person who builds the tools — several features shipped within a day of someone asking.
Contact
The fastest route is the feedback button at the bottom of any tool page — it goes straight to me, and you can leave your email if you'd like a reply. For school- or district-level questions, see lans.cloud for schools. If a tool saves you time and you feel like it, there's a coffee button — but the tools are free either way.
