I think that you probably can. I’m sorry, my background is in safety critical, not commercial. . You have also limited to Swedish law, about which I know nothing practically so I’m going on what I know. I want to stress that ** I am not a lawyer and this is not legal advice**, (note use of bold instead of scary caps ) I am working on the things that I know have to be be avoided and/or must be checked during compliance audits and assessments from a safety critical perspective, so this is all written ‘as is’ and caveat emptor.
Most jurisdictions have a concept that that you cannot disclaim liability for something for which you are liable, so many of the liability disclaimers are dodgy at best. This one says explicitly that the service is provided as is and so on which is a good thing to have, it removes ambiguity.
One thing I would recommend strongly is getting rid of the phrase ‘We will try our best’ - saying anything like ‘trying our best’ or ‘make best endeavours’ is a world of pain. The UK, the EU and the US all recognise that as meaning you will sell off all your possessions, liquidate your company and drive yourself into bankruptcy and other equally horrifying things, to keep the service going. As it is considered to trump other parts of contracts, a previous employer dismissed someone quite senior on the spot for using the term ‘best’ in a contract.
So putting my money where my muzzle is, perhaps:
Disclaimers:
We provide this service to you “as is” and “as available”, without warranty of any kind. We want to keep it a fun and safe place to hang out, but we cannot promise that it will always be available or that it will be fit for any particular purpose.
Some places find that it helps them feel better if they put in a statement along the lines of 'This service is not designed for use in an emergency, for personal protection and safety or for the protection of property.
For more the general disclaimer, can I suggest this site as a reasonable starting point? Disclaimer Examples - TermsFeed Also look at things like the GNU licence and the FreeBSD licence.
I really cannot stress enough though, I am not a lawyer and do not understand Swedish law. If you’re at all unsure over something like this, it is worth consulting Citizen’s Advice Bureau or even shelling out for a couple of hours of a commercial lawyer’s time.
