Terms of use
Last updated: 6 November 2026
These terms apply to the use of Focusium ("the extension"), published by Gersi Kereci, Karl-Köglsperger-Str. 9, 80939 München, Germany, info@getfocusium.com ("we").
1. What Focusium is
Focusium is a browser extension that helps you focus: during focus it limits sites and tabs, and quiets notifications and sound. It is a self-help tool. It is not a medical, therapeutic or parental-control product.
2. Using the extension
You may install and use Focusium for personal and professional purposes, free of charge. You may not sell it, redistribute modified copies, or remove the notices in it.
3. How it affects your browser
While a focus session runs, Focusium can close new tabs, redirect websites to its own pages, block website notifications and mute tabs. Please save your work before a focus starts. Content that exists only inside a page (for example an unsent form) may not survive a tab being closed or redirected.
4. Availability and changes
Focusium is provided as it is. We may update, change or discontinue it. Features that depend on third-party websites (for example hiding feeds) may stop working when those websites change. Joining a waitlist is not an order or a promise of a release date.
5. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act (Produkthaftungsgesetz). For slight negligence we are liable only for the breach of an essential obligation (one whose fulfilment makes proper use possible and on which you may rely), limited to the damage typical and foreseeable for this kind of product. Otherwise our liability is excluded. Since Focusium is free of charge, the statutory rules on gifts (§§ 521, 524 BGB) apply in addition where they limit liability further.
6. Privacy
How information is handled is described in the privacy policy.
7. Applicable law
German law applies. If you use Focusium as a consumer, this choice of law does not take away the protection of mandatory rules of the country where you live.
