How KitLumo stays free

Supported by ads. Helped by people.

Clearly labelled ads fund the website so everyone can use every tool for free. If KitLumo saves you time, you are also welcome to make an optional donation to help pay for hosting and keep the tools available.

Donating never unlocks extra features. Every tool remains free for everyone.
Donations are not enabled right now.

How it works

Free means free.

KitLumo is built around small, focused utilities. No login walls, no artificial limits and no AI layer where a reliable tool will do.

Every tool currently available works directly on the phone, tablet or computer you are using. Anything you type, paste, calculate or open in a tool is not sent to us, and KitLumo does not save a copy.

Your saved and recently used tool shortcuts are stored only in your browser on this device. When you use “Report a problem” or “Request a free tool,” only that message and any email address you choose to add are sent to KitLumo.
