GuessMate is a guess-who game for you and your mates. This page explains what information the app collects, why, and what it never does with it.
GuessMate Pro is a one-off purchase made through Stripe's hosted checkout. To match the purchase to your GuessMate account, we send Stripe a unique reference for the account you are signed into. Stripe collects and processes the payment details, and any contact or billing details you enter on its checkout page. GuessMate does not receive your full card number or security code. Stripe sends us the payment confirmation and account reference needed to enable Pro and help resolve purchase questions.
Stripe handles payment information under its own privacy terms. Read the Stripe Privacy Center.
When you choose to add a profile picture, you are choosing to show it with your screen name to people you play online, including players you're matched with in Quick match, and beside your name on the leaderboards, which anyone using GuessMate can see. If you've saved your progress, a small copy is stored with your account so it can appear on leaderboards and your other devices; the full-size picture stays on your phone. If you don't want other players to see a picture, leave it blank and the game shows your first initial instead.
While GuessMate is open, it tells our server you're online, so your mates (only people you've both agreed to be mates with) can see you're on when they go to invite someone. Nobody else can see it.
If you turn on notifications, your phone gives us an address we can send notifications to on that phone. Notifications are off unless you choose to enable them in GuessMate and allow them in your phone or browser. When someone searches for your screen name and taps Add, GuessMate creates a mate request and, if you have notifications enabled, sends a push notification to your registered phone or phones. We may also notify you when someone says yes to your request. We use the push address only to deliver these mate-related notifications. Turn notifications off in GuessMate Settings or in your phone's or browser's notification settings. If you turn them off in GuessMate or log out, that phone's address is removed from our server.
If you use Report a problem, we receive what you type plus a few details to help fix it: your screen name and player tag, the version of the game, your screen size, and the type of phone and browser you're using. These are only used to fix the problem you reported.
Photos never leave your device except when you choose to play with them. If you build a board out of your own photos for Pass & Play, those pictures stay on your phone — full stop. If you use a photo board to play someone online, the pictures are sent only to the specific person you're playing that game with, so they can see the board too. They are never stored on a server, never shown to a stranger, and never used for anything except that game.
Account details, game results and mates lists are stored with our database provider (Supabase), used to run the app. Stripe processes payment details through its checkout. We use Netlify Web Analytics to understand page views, which pages are visited, where visits come from, and broad visitor locations. Netlify says its analytics use server request logs and do not use cookies or client-side tracking. Local game settings — like sound volume or the last board you played — are stored on your own device and never sent anywhere.
To delete your GuessMate account: open GuessMate, tap your picture to open Your Profile, scroll to the bottom and tap Delete my account, then confirm twice.
This deletes from GuessMate: your account and email address, your screen name, player tag and profile picture, your level and XP, your badges, your game record, your Daily scores, your mates list and any problem reports you sent. Everything stored on the phone itself is wiped at the same time. Deleting your GuessMate account does not delete information Stripe holds in its own systems. If we need to retain a limited purchase record for legal, accounting, security or support reasons, it will not keep your GuessMate account active. Contact us if you have questions about a purchase record; Stripe's own privacy terms explain its handling and retention of payment information.
If you can't get into the app, email guessmaster@guessmate.co.uk from the address you signed up with and we'll delete it all by hand within 30 days.
GuessMate is rated for a general audience and isn't aimed specifically at children. We don't knowingly collect more information from a child than from any other player, and the same rules above apply to everyone.
If this page changes in a way that matters, the date at the top will change too. Nothing here changes retroactively without telling you.
