Acceptable use policy

Version 2026-11-10.a7056505

Last updated: 2 November 2026

1. What this policy covers

1.1 This policy is part of our terms of service. It applies to everyone in your team and to every app you run on Clusterz, including what the people who use your apps put in them.

1.2 It also explains how anyone can report illegal content on Clusterz to us, and what we do about a report, as the EU Digital Services Act requires.

2. Use Clusterz within the law

You must use Clusterz, and run your apps, only in ways that are lawful. This includes the law on data protection, consumer protection and intellectual property, and any licence your work needs, such as a banking licence.

3. Content you must not host or send

• Content that sexually abuses or exploits children.
• Content that supports terrorism, or that incites violence or hatred against people, as the law defines it.
• Malware, or content made to trick people into giving away passwords, money or data.
• Content that infringes someone else's copyright, trade mark or other rights.
• Any other content that is illegal under European Union law, Estonian law or German law, or under the law that applies to you and the people who use your app.

4. Things you must not do

• Attack, scan or probe other systems, including other customers' apps on Clusterz, or try to reach another team's apps, data or settings.
• Test the security of Clusterz or of other customers' apps without our written permission. You may test your own apps, as long as the tests do not touch other teams or the systems you share with them. To test more, ask at contact@clusterz.eu, and we do not refuse without good reason. If you find a weakness, tell us at the same address.
• Send spam: messages in bulk that people did not ask for.
• Disrupt or overload Clusterz, or the networks it relies on.
• Get round our limits or our billing, for example by opening more accounts or teams to get more free trials.
• Pretend to be someone else, or hide who runs an app in order to deceive people.
• Help someone else do any of these things.

5. Fair use of shared resources

A plan includes an amount of memory and processing power and a number of apps. You cannot create more apps than your plan allows. Memory and processing power above the amount included are charged by the hour, as section 5.5 of the terms describes. The apps of a bundle are covered by the bundle's price, not by a plan. We do not charge separately for disk space, data transfer or build time. One build can run for up to 15 minutes. Use these resources to run your apps. If your use harms the service for other customers, we ask you to reduce it, and we may limit it if you do not.

6. Your apps' users

You are responsible for what the people who use your apps do with them and put in them. If your app lets people publish content, the Digital Services Act may require you to offer them a way to report illegal content to you.

7. How to report illegal content

7.1 Anyone can report content on Clusterz that they believe is illegal. Email contact@clusterz.eu, in Estonian or English, with:

• the exact web address of the content, and any other detail that helps us find it;
• why you believe the content is illegal;
• your name and email address, unless your report concerns the sexual abuse or exploitation of children;
• a statement that you believe in good faith that your report is accurate and complete.

7.2 We use your name and email address only to handle your report, and as the law requires. We tell the customer concerned who made it only where that is strictly necessary, for example in a dispute about copyright. Our privacy policy explains how we handle this data.

8. What happens after a report

8.1 We confirm by email, without undue delay, that we received your report.

8.2 A person on our staff reviews it. No automated tool judges the content of your apps. Our security tools detect attacks and unusual activity automatically, and a person decides what to do with what they find.

8.3 Where it is safe to, we first ask the customer who runs the app to deal with the content, and give them a short time to do so, set by how serious it is. If the content is still there after that, we act ourselves.

8.4 We decide in a timely, careful and objective way. We then tell you our decision and how you can challenge it.

9. What we may do, and how we tell you

9.1 If content or an app breaks the law, our terms or this policy, puts Clusterz or other people at risk, or the law or an authority requires it, we may:

• ask the customer to remove or fix it;
• remove the content or block access to it;
• stop the app;
• suspend the team's access to Clusterz, so that its members cannot use the dashboard, the command-line tool or the API. Its apps keep running unless we also stop them;
• end the contract, as section 14.6 of the terms describes.

We choose the step that fits the problem. We delete an app only as section 14.6 of the terms allows.

9.2 When we take one of these steps, we email the owners and admins of the team a statement that says:

• what we did, how far it reaches, and for how long;
• the facts that led to it, including whether it followed a report;
• whether automated means found the content or made the decision;
• the law, or the part of our terms, that the step rests on, and why the content falls under it;
• how to ask us to review it, and the other ways to seek redress in section 11.

9.3 We send this statement unless the law forbids it.

10. Threats to life or safety

If we learn of anything that makes us suspect a crime that threatens someone's life or safety, we tell the police of the EU country concerned at once. If we cannot tell which country that is, we tell the Estonian police or Europol. Our report may include data from the app concerned. We tell the customer afterwards, unless the law forbids it.

11. Asking us to review a decision

11.1 The customer concerned, or the person who made the report, can ask us to review a decision within six months of it: reply to our email or write to contact@clusterz.eu. Where we can, someone other than the person who took the decision reviews it. We tell you the outcome without undue delay, and we reverse the step if it was wrong.

11.2 You can also complain to Estonia's Consumer Protection and Technical Regulatory Authority (Tarbijakaitse ja Tehnilise Järelevalve Amet, TTJA), which supervises us under the Digital Services Act, or to the authority that supervises digital services in your own EU country. You can also go to court.

12. Contact points

12.1 For authorities: authorities of EU member states, the European Commission and the European Board for Digital Services can reach us at contact@clusterz.eu, in Estonian or English.

12.2 For users and anyone else: email contact@clusterz.eu, use our help form, or write to Zer0Paper OÜ, Ahtri tn 12, 15551 Tallinn, Estonia, in Estonian or English. A person, not an automated tool, reads every message sent to this address or through the form. The assistant is not this contact point.

13. Changes

We email the owners and admins of every team at least 30 days before a change to this policy applies, unless the law makes us change it sooner, as section 16 of the terms describes.
