Terms of Service
Last updated: 5 October 2026
These terms apply to your use of Nat21, operated by Michal Petr. By using Nat21 you agree to them. If you don't agree, please don't use Nat21.
The service
Nat21 is a free virtual tabletop for tabletop role-playing games, run as a hobby project. Features may change over time, and the service may be interrupted or discontinued at any time.
Your account
You sign in to Nat21 with your Google account and must be at least 15 years old to do so. You are responsible for what happens under your account, so keep your Google account secure.
Your content
You keep ownership of everything you create or upload to Nat21, such as games, maps, text and images. You give us permission to store, process and display that content to you and to the members of your games, only as far as needed to run Nat21.
You are responsible for your content. Only upload material you have the right to use; for example, don't upload maps or artwork that you aren't allowed to share.
Acceptable use
When using Nat21, don't:
- break the law or infringe the rights of others,
- upload illegal, hateful or harassing content, or harass other users,
- try to access accounts or data that aren't yours,
- try to disrupt or overload the service, or access it in bulk with automated tools.
Suspension and termination
We may suspend or delete accounts and content that break these terms. You can stop using Nat21 at any time and ask us to delete your account, as described in our Privacy Policy.
No warranty
Nat21 is provided "as is", without warranties of any kind. We do our best to keep your data safe, but we can't guarantee it will never be lost, so keep your own copies of anything important.
Limitation of liability
To the extent permitted by law, we are not liable for any indirect or consequential damage, or for any loss of data, arising from your use of Nat21. Nothing in these terms limits any rights you have as a consumer under the law that applies to you.
Changes to these terms
We may update these terms. When we do, we will change the date at the top of this page, and we will let you know in Nat21 about significant changes. Continuing to use Nat21 after a change means you accept the updated terms.
Governing law
These terms are governed by the laws of the Czech Republic. This does not take away any protection you have under the mandatory consumer laws of the country where you live.
