Your wiki is publicly accessible at https://personalwiki.com.de/wikis/username. Anyone can read it (just like a personal website), but only you can edit it using your password.
You can delete your wiki anytime with no data retention. If you've lost your password and need to delete your wiki, feel free to contact Clelia, the project creator.
Important: While your wiki is public, we use your data solely for hosting and serving your wiki, nothing else.
