Support Center
Email is the support channel for Zapp Chess. This page tells you how to reach the team, what to put in a bug report, and where the answers that are already on the site live.
⏱️ We typically respond within 24-48 hours
How to reach us
Send an email to hello@zappchess.com. The same address handles questions, bug reports, feedback, and account requests. Put one topic in each message, and name the topic in the subject line, for example "Bug report", "Account deletion", or "Subscription". We usually reply within 24 to 48 hours.
What to include in a bug report
A report that covers the points below can usually be fixed without a second email:
- Your device model and its operating system version, for example "Pixel 8, Android 15" or "iPhone 14, iOS 18".
- Where the problem happened: the Android app, the iPhone app, or the website. For the website, add the page address.
- The app version, if you can find it in the store listing on your device.
- The steps you took before the problem, what you expected to happen, and what happened instead.
- A screenshot or a screen recording of the problem.
- For a problem in a game: the date and approximate time of the game, your username, and your opponent's username.
Account and data questions
An account holds a username, an email address, and a profile picture. You can ask for deletion of your account and the data linked to it at any time by email. State the username of the account in the message. The privacy policy lists what we collect, how long we keep it, and the rights you have over your data.
Subscriptions and payments
Zapp Chess is free to download, and every game is free. The optional premium subscription described in the terms is billed monthly through Google Play. You can cancel it at any time in your Google Play account settings. The cancellation takes effect at the end of the current billing period, and premium features stay active until then. Partial billing periods are not refunded. Section 7 of the terms and conditions has the full text. When you write to us about a payment, include the order number from the store receipt.
Play and learn on the website
You do not need the app to play. The home page runs a game against the computer in the browser. The analysis board runs Stockfish in your browser and reviews a pasted PGN. The chess clock times a game on a real board. The chess rules reference, the opening trainers, and the blog cover the rules, thirty-two openings, and beginner strategy.
Press and partnerships
The press page has a description of the game, logo files, and the store links. For interviews and partnership requests, use the same email address with "Press" in the subject line.
