Terms

Last updated 2026-11-11.

1. What these terms cover

1.1 These terms are the agreement between you and the operator of hiza named in the imprint for using hiza, a messenger. 1.2 How we handle your data is in the privacy policy.

2. Who can use hiza

2.1 You must be at least 16 years old. 2.2 You sign in with your Coredo Account; its own terms apply to it. 2.3 One person may hold one hiza account per Coredo Account. 2.4 While hiza is in its beta, we may limit who can sign up.

3. Your account

3.1 Keep your devices and your Coredo Account secure; you can see and sign out every device in Settings. 3.2 You can delete your hiza account at any time in Settings, or your whole Coredo Account, which deletes your hiza account too.

4. How hiza works

4.1 Chats in hiza are cloud chats: they are stored on our servers so that all your devices stay in step. They are not end-to-end encrypted, and people operating the service could technically read them. We only look at content when someone reports it to us or the law requires it (§6). 4.2 Files and photos are stored encrypted. 4.3 Hiza is offered as it is during the beta: features may change, and we aim for, but do not promise, constant availability. 4.4 Private chats are the exception to 4.1: they are end-to-end encrypted, and we cannot read them. On the web they rely on the code our site serves. Keep your recovery code safe: without it, or another of your devices, a new device cannot read your private chats' history, and we cannot restore it for you.

5. Rules for content and conduct

You are responsible for what you send. In hiza you may not:

• 5.1 Nothing illegal. No content or conduct that is illegal under EU or German law.
• 5.2 No spam or scams. No unsolicited bulk or automated messages, no fraud, phishing or pyramid schemes.
• 5.3 No harassment or hate. No harassing, threatening or degrading people, and no incitement against people for who they are.
• 5.4 No violence. No threats of violence, no glorifying or calling for it, no terrorist content.
• 5.5 No sexual exploitation. Nothing sexual involving minors, and no intimate images of anyone shared without their consent.
• 5.6 No impersonation. No posing as another person or organization to mislead.
• 5.7 No attacks on hiza. No malware, no scraping or harvesting people's data, no getting around limits or security.

6. Reports and moderation

6.1 You can report a message, a person or a group from its menu; anyone can send us a notice of illegal content on the report page. 6.2 People at hiza review reports, usually within 72 hours; nothing is decided by software alone. They see what was reported, as the reporter saw it, and nothing else of the chat. 6.3 If content breaks §5 or the law, we may remove a message for everyone, or suspend an account (sign-in refused and every device signed out). Suspension is for serious or repeated breaches. 6.4 When we act, the person affected gets a statement of reasons in Settings → Notices and reports: what we did, on which clause or law, and the facts. The reporter learns the outcome. 6.5 You can ask us to review a decision about you within six months: from that page, or through the contact page if your account is suspended (internal complaint). You can also turn to a certified out-of-court dispute settlement body, or go to court.

7. Ending

7.1 You can stop using hiza and delete your account at any time. 7.2 We may end or suspend an account under §6.3, and end the service as a whole with 30 days' notice, giving you time to download your data.

8. Liability

8.1 We are liable without limit for intent and gross negligence, and for harm to life, body or health. 8.2 For slight negligence we are liable only for breaching an essential obligation, limited to the damage typical and foreseeable for this kind of service. 8.3 Statutory consumer rights remain unaffected.

9. Changes to these terms

9.1 We tell you about changes at least 30 days before they take effect, in hiza. 9.2 If you do not agree, you can delete your account before then.

10. Law

10.1 German law applies, without the UN Convention on Contracts for the International Sale of Goods. If you are a consumer living in another EU country, the mandatory protections of that country's law stay with you.
