Lumenhart
Built with care, for the people who use it.
Lumenhart is a small, independent team making private, beautifully simple tools for everyday online life. We’re independent, so we answer only to the people who use our products.
Why we exist.
So much of who we are now lives online: years of posts, comments, likes and saved links, spread across the platforms we use every day. Most of it was never meant to last forever, yet tidying it up is slow, fiddly and often means trusting a stranger with your password.
We think it should be simple, and private. So we build focused tools that run on your own device, show you exactly what they’ll do, and wait for your say before they do anything.
Activity Cleaner is the first of them. There’s more to come.
What we stand for.
Four principles shape every decision we make, from the first sketch to the last line of code.
Privacy first.
Your content stays on your device. We design every product so that we never need to see it.
You’re in control.
Nothing happens without your say. You always see what will change before it does.
Craft in the details.
Clear words, calm design and software that simply works. We sweat the small things so you don’t have to.
Fair and straightforward.
Honest pricing, a free way to start, easy cancellation and a 14-day money-back guarantee.
How we make money.
We charge a fair price for optional paid plans. That’s it. Our business only works if our products are good enough to pay for.
We’d love to hear from you.
