Terms & Conditions

You must be at least 13 years old to create an account. If you are under 13, a parent or legal guardian must register and manage the account on your behalf and is responsible for your use of the Service. By registering you confirm that the information you provide is accurate and that you will keep it up to date. You are responsible for keeping your password and account credentials confidential and for all activity under your account. Notify us promptly at support@jongzo.com if you believe your account has been compromised.

Jongzo is a scoring companion for Hong Kong style Mahjong. It records hands, calculates faan and payouts, tracks match history, supports online private rooms, friends, daily puzzles, and a Mahjong Solitaire mode. The Service is provided for personal, recreational use. We may update, suspend, or discontinue features at any time without notice, and we do not guarantee that the Service will be uninterrupted or error-free.

You agree not to misuse the Service, including by: using it for any unlawful purpose or to facilitate real-money gambling; attempting to access data you are not entitled to; reverse-engineering, scraping, or overloading the Service; impersonating others or providing false identity information; sending spam or abusive messages through the contact or friend features; or attempting to disrupt other users' games.

Jongzo is a scorekeeper only. Any settlement of winnings or payments between players happens entirely between you and the people you play with. The Operator takes no part in any financial transaction between players and is not responsible for enforcing or collecting any debts.

Online rooms are private and accessed by a code you share. You are responsible for who you invite. Friend requests, nudges, and match history are stored to provide the social features of the Service. You may remove friends, delete saved matches, or request deletion of your account at any time.

You may upload a profile photo and contribute display names, messages via the contact form, and game data. You retain ownership of your content but grant Jongzo a limited licence to host, store, and display it solely to provide the Service. You must not upload content that is unlawful, infringes others' rights, or is harmful. We may remove content that breaches these Terms.

The Service, its design, tile artwork, logos, and software are owned by the Operator and protected by intellectual property laws. Nothing in these Terms grants you any rights to the Service other than a personal, non-exclusive, revocable licence to use it.

The core Service is currently free. Where paid features are introduced, they will be clearly disclosed before purchase. As an individual operating from the UK, the Operator may charge UK VAT where applicable. Refunds, where offered, will be handled in line with applicable UK consumer law.

The Service is provided "as is" without warranties of any kind. Scoring calculations are provided as a helpful aid and may not reflect every local house rule; you are responsible for verifying scores before any settlement. To the extent permitted by law, the Operator is not liable for indirect or consequential losses, or for any dispute between players. The Operator's total liability is limited to the amount you have paid in the preceding 12 months, or £100, whichever is greater. Nothing in these Terms excludes liability that cannot be excluded under UK law.

You may stop using the Service and request account deletion at any time. The Operator may suspend or terminate access if you breach these Terms or for any operational reason.

We may update these Terms from time to time. Material changes will be notified through the Service or by email. Continued use after changes take effect constitutes acceptance.

These Terms are governed by the laws of England and Wales. If you have a complaint, please contact support@jongzo.com first. If we cannot resolve it, you may refer it to the Alternative Dispute Resolution (ADR) scheme or, as a last resort, the courts of England and Wales. As a UK trader, the Operator complies with the Consumer Rights Act 2015 and applicable online and distance selling regulations.

The Operator is an individual sole trader based in the United Kingdom. For any question about these Terms, email support@jongzo.com. Our privacy practices are set out in our Privacy Policy.
