Report illegal content and contact us

Last updated: October 9, 2026

Compound is run by Hieu Luu, a sole proprietor trading as Compound, 9386 Cheverny Way, Sacramento, CA 95829, United States. This page gives our contact points under the EU Digital Services Act (DSA) and explains how anyone, whether or not they use Compound, can tell us about content they believe is illegal. It also covers reports and complaints from the UK under the Online Safety Act 2023.

If someone is in immediate danger, contact your local emergency services first (112 in the EU, 999 in the UK, 911 in the US).

Contact point for authorities

Authorities of EU Member States, the European Commission and the European Board for Digital Services can contact us at hello@compoundfit.app, using the subject line "DSA authority contact". This is our single point of contact under Article 11 of the DSA. We accept communications in English.

Postal address: Hieu Luu (Compound), 9386 Cheverny Way, Sacramento, CA 95829, United States.

Contact point for users

If you use Compound, or want to, you can reach us directly at hello@compoundfit.app. This is our single point of contact under Article 12 of the DSA. A person reads and answers every message; we do not use a chatbot or automated replies to deal with you. You can write to us in English.

Report illegal content

Use this form to tell us about a post, comment, profile or other content on Compound that you believe is illegal. You do not need a Compound account. If you have the app, you can also report any post, comment or user from its menu.

To report a copyright infringement, follow the copyright process in section 12 of our Terms. To report content that breaks our rules but is not illegal, use the in-app report option or email us.

Most Compound content has no public web address, so describe it precisely: date, what it shows, the words used, or a link if you have one.
Explain your reasons as fully as you can, including the law or country concerned if you know it.
Name and email are needed for us to confirm receipt and tell you our decision. You may leave them out only if you are reporting child sexual abuse material.

We use what you send only to handle your report, as described in our Privacy Policy.

What happens after you report

  • If you give us your email address, we confirm that we received your report.
  • A person reviews every report. We do not use automated tools to decide on reports.
  • If the content is illegal, or breaks our Terms, we remove it or restrict access to it, and may suspend or close the account that posted it.
  • We tell you what we decided and why, and how you can challenge the decision.
  • We tell the person who posted the content what we did and why (see below).

When we act on your content

If we remove your content, stop it from being published, or suspend or close your account, we tell you clearly and specifically why. Our statement says what we did, the facts behind it, whether an automated tool was involved, which rule or law the decision relies on, and how you can challenge it.

One tool is automated: before a post, comment, profile bio, name or handle is published, it is checked against a list of slurs, sexually explicit terms and terms that promote eating disorders. Content that matches is not published, and the app tells you at that moment. No person reviews that check before it happens. Everything else, including every report, is decided by a person.

How to challenge a decision

If you disagree with a decision we made about your content, your account or your report, email hello@compoundfit.app with the subject line "Challenge a moderation decision" within six months of the decision. A person who looks at it afresh will review it and reply. If we got it wrong, we reverse it. Challenging a decision with us does not affect your right to go to court.

Threats to life or safety

If we become aware of anything that gives rise to a suspicion that a criminal offence involving a threat to someone's life or safety has taken place, is taking place or is likely to take place, we promptly inform the law enforcement or judicial authorities of the country concerned, or Europol where we cannot identify that country, and give them the information we have.

If you are in the UK

You can use the form above and the in-app report option to report content that you believe is illegal in the UK, and email us to complain about content, about how we handled a report, or about action we took against your content or account. We handle UK reports and complaints in the same way as described on this page.
