Privacy and terms
Last updated November 12, 2026
PongHQ is a table tennis coaching site run by Yijun (Tom) Feng in the United States. This page says what we collect, what we do with it, and the terms of using the site. It is written to be read.
What we collect
- Your name and email address, which you give when you send a question. You do not need an account to ask.
- Your questions to the coach, your follow-ups, and the coach's answers.
- One cookie. See Cookies below.
We do not ask for payment details during early access.
How we use it
- Your email address is used to send you the coach's answer and to reply to your follow-ups.
- Your email address is also used to tell you when new features open, such as the AI coach and video analysis. You can ask us to stop these emails at any time.
- Your question is read by Tom Feng, who answers it personally.
- Your question and the answer are used to build and train the AI coach. See the next section.
We do not use your email address for anything else, and we do not sell it or give it to advertisers.
Your questions and the AI coach
We are building an AI coach. The questions players send, and the answers Tom Feng gives, are what it learns from. When you send a question, you agree to this use by ticking the box on the form.
- What is used: the text of your question, any follow-ups, and the coach's answers.
- What is removed first: your name and your email address. They are not part of what the AI coach learns from.
- How it is used: questions and answers are added to the coaching knowledge that the AI coach draws on, and may be used to train and test it. We use AI tools from an outside provider to do this, so the text may be processed by that provider on our behalf.
- What other players may see: the AI coach may give other players advice that was shaped by your question. It will not show them your name or your email address.
- Details that identify you: if your question includes something that could identify you, such as your club or an opponent's name, we try to leave it out. If you want to be sure, tell us.
- Saying no: you can ask us at any time not to use your questions for the AI coach, or to delete them. To do that, email tomfeng@ponghq.app. We will still answer your questions.
Who sees it
The coach sees your questions. Other players do not. We do not sell your information and we do not share it with advertisers.
We use other companies to run the site: one to host it, and email services to send and receive messages. They handle your information only to provide that service to us.
Features that are coming
When the AI coach and video analysis open, they will handle more: your conversations with the AI coach, and match videos you choose to upload. Those will be processed by an AI provider on our behalf. We will update this page before those features open, and you decide whether to use them.
Your choices
- You can ask for a copy of your information, or ask us to delete your questions and your details. To do that, email tomfeng@ponghq.app.
- You can ask us not to use your questions for the AI coach. See Your questions and the AI coach.
- The site itself does not store your question: it is sent to the coach as an email. We keep that email, and any coaching notes made from it, until you ask us to delete them.
Age
The site is not meant for children under 13, and we do not knowingly collect their information. Players under 18 should sign up with a parent or guardian's permission.
Terms of use
- What you get. During early access the site is free. You can send up to 3 new questions a week. The coach answers personally, and we aim to answer within 24 hours. Now and then, for example during a tournament, an answer may take longer.
- Coaching, not medical advice. Answers are table tennis coaching based on what you tell us. They are not medical advice. If you are injured or in pain, see a doctor or physiotherapist before you train.
- No guarantee of results. We want you to improve, but we cannot promise a rating or a result.
- Be respectful. Do not send abusive, unlawful or spam messages. We may stop answering someone who does.
- The coaching content. The answers and coaching material are for your own use. Please do not republish or sell them.
- Changes. The site is in early access and will change. Features, limits and prices may change, and we will say so here before a paid plan starts.
Changes to this page
If we change this page in a way that matters, we will update the date at the top and tell members by email.
