Help us help you faster

Please include:

For sponsorship or payment questions: the email address you verified with, the spot number (#1–#10) and the payment reference from your confirmation email. Write from that same email address if you can: we can only discuss a sponsorship with its verified owner.
For game problems: your device, browser and version, what you were doing, and a screenshot if possible.
For online matches: the 6-character room code and roughly when it happened.

Never send us your full card number or bank details. We never ask for them, and we don’t need them to help with a payment.

Common questions

Sponsorships and payments

How does bidding on a sponsor spot work?

There are ten spots in the stadium (six court boxes and four screens), each with its own running bid. The highest paid total on a spot is shown in the game, with no time limit, until someone beats it. If you already have a bid on a spot, you only pay the difference to raise it. The full rules are in our Terms of Service.

I paid but my logo isn’t showing.

Some payment methods take a little while to confirm; your logo goes live as soon as the payment clears. If someone else’s bid landed just before yours while you were paying, your payment still counts toward your total on that spot but may no longer be the top bid. Your confirmation email says which of these happened. If neither explains it, email us with your payment reference.

I was outbid. Can I get my money back?

No. Being outbid is part of how the spots work, and your total stays on the spot so you can raise it later by paying only the difference. See our Refund Policy for the cases where we do refund.

I was charged twice, or charged a different amount than shown.

Email us with your payment reference. We refund duplicate and incorrect charges in full. See the Refund Policy.

I closed the payment page. Was I charged?

No. You are only charged if you complete payment on the Stripe checkout page. An unfinished checkout expires on its own, and you can also cancel it from the sponsorship screen.

Can I change my logo, name or website on a spot?

Email us from your verified address with what you’d like changed. Any new artwork must follow the same content rules as the original.

I don’t see a charge I recognize from “ProTennis” or Rytham Sequence LLC.

Email us with the date and amount and we’ll look it up. If you believe your card was used without permission, also contact your card issuer.

The game

Do I need an account to play?

No. The game is free and needs no account. Your player name and choices are saved in your browser only.

The game is slow or won’t load.

ProTennis runs in 3D in your browser. Use an up-to-date version of Chrome, Edge, Firefox or Safari, make sure hardware acceleration is turned on in your browser settings, and close other heavy tabs. If it still won’t load, email us your device and browser details.

My friend can’t join my online room.

Check that they typed the 6-character code exactly, or send them the invite link from the room screen. A room holds two players. If the connection drops, create a new room and share the new code.

Reports and privacy

A sponsor logo is offensive, misleading or uses my trademark or copyright.

Email us the spot number and why it should come down. For intellectual property claims, include your contact details, the work or mark you own, and a statement that you believe in good faith the use is unauthorized. We review every report and remove content that breaks our content rules.

How do I access or delete my personal data?

Email us from the address you used. Our Privacy Policy explains your rights and how we handle requests.
