Terms of use

Last updated October 22, 2026

These terms are an agreement between you and Lewis Hussey, who runs K0mplexity from the Netherlands. By creating an account you agree to them and to the privacy policy. If you don't agree, please don't use K0mplexity.

Testing

K0mplexity is still being tested. Features can change or disappear, things can break, and accounts and data on the server may be reset during testing. Please keep this in mind and send any problems you find to support@k0mplexity.com.

Who can use K0mplexity

Your account

You sign in with a passkey stored on your phone and in your iCloud Keychain or Google Password Manager. Keep your phone and these accounts secure, because anyone who can use your passkey can use your account. Your username must not pretend to be someone else or be offensive.

No tolerance for abuse

K0mplexity has no tolerance for objectionable content or abusive behavior. You must not use it to:

Reporting, blocking and moderation

You can block anyone, and report anyone from their profile or your chat with them. Moderators review reports and can ban accounts that break these terms, without warning when the situation calls for it. A banned account can no longer use K0mplexity. Because messages are end-to-end encrypted, moderators can only read the texts you choose to attach to a report.

Your content

You keep ownership of everything you post and send. You give us permission to store and show your public profile to other users and to deliver your encrypted messages, only as far as needed to run K0mplexity. You are responsible for what you share and must have the right to share it.

Meeting people

We don't run background checks and can't vouch for anyone you meet through K0mplexity. Take care when meeting someone in person: meet in a public place and tell a friend where you are going. Interactions with other users are your own responsibility.

Ending your account

You can delete your account at any time in Settings. We may suspend or end your account if you break these terms, if the law requires it or if we stop running K0mplexity.

To protect your privacy, we delete accounts that haven't been used for 12 months, along with all of their data on the server. If notifications are on, you get a reminder 30 days before.

Liability

K0mplexity is provided as it is, without any guarantee that it will always work or be free of errors. As far as the law allows, we are not liable for indirect damage, lost data or the behavior of other users. Nothing in these terms limits liability that can't be limited by law, such as for intent or gross negligence, or takes away your rights as a consumer.

Changes

We may update these terms. The date at the top shows when they last changed, and for important changes we will let you know in the app. If you keep using K0mplexity after a change, the new terms apply.

Law and disputes

These terms are governed by Dutch law. Disputes go to the competent court in the Netherlands, unless the law of the country you live in gives you the right to go to a court there.
