Clag - last updated 31 October 2026
Clag is a card game made by Peter Connor. This page explains what information the game uses, who can see it, where it goes and how long it is kept. "We" means Clag and its developer.
You can play Clag without signing in and without an account. We never ask for your email address, your contacts or your location.
The app reports what you do in the game, so we can see how it is used. For example, it reports when you start or finish a game, a daily challenge, a lesson or a puzzle. It also reports when you take a puzzle hint or open a replay, the Store or a look's preview. Each report carries a random install ID that the app makes the first time it opens. The install ID is not made from your device or from who you are. If you are offline, the reports wait on your phone and are sent when you are back online.
If you play the season challenges without signing in, your progress is kept on our server under your install ID. When you sign in, it moves to your online profile.
If you join an online table without signing in, the other players see the name you typed. Our record of the game keeps it too (see Online games below).
If you are signed in to Game Center on an iPhone or iPad, or to Google Play Games on Android, Clag makes an online profile for you as soon as it opens. This happens whether or not you play online. Your profile keeps your progress the same on all your devices. It also lets you play ranked games, add friends, enter tournaments and appear on leaderboards.
From Game Center we receive your player ID and your Game Center name. We never receive your Apple ID or your email address. From Play Games we receive your player ID and your Play Games name.
On iPhone and iPad, your profile is stored under a code made from your Game Center player ID. The code cannot be turned back into the ID. On Android, your profile is stored under your Play Games player ID.
Your profile holds:
Because your profile holds your install IDs, the app's reports from those devices are linked to your profile.
Other players can see your name, level and rating, how many rated games you have played and left early, your achievements and trophies, and the looks you wear, including your flag. They see these at an online table, on your player card, on leaderboards and on tournament pages. Anyone using the app can read leaderboards, tournament pages and player cards, whether they are signed in or not. Anyone using the app can also see the name of each host in the list of open public tables.
Each profile has an ID that the app uses to tell players apart. When the app shows a leaderboard, a tournament page or the results of a name search, our server sends it this ID too. On Android, this ID is your Play Games player ID.
Signed-in players can find you by name to send you a friend request, unless you have turned friend requests off. Your friends see your name and level, and whether you are offline, online, at a table or playing. While your table has a free seat, they also see its code so they can join you.
If you choose to show that you are looking for a game, signed-in players see your name, your seat ring, what you are doing and when you were last seen.
When you play online, your name and every move you make go to our server so the game can run.
We keep a record of every online game, whether it is ranked, private or played by guests. A record holds each player's name, the profile ID of each signed-in player, the scores, the result and every bid and card played. We use these records to look into problems and to see how the game is played. They have no end date. Deleting your profile does not remove them.
For each rated game, your profile also keeps your score, your rating before and after the game, and the profile IDs of the other players.
If you enter a tournament, we keep your entry, your scores and when you played each match. Anyone using the app can see every player's name, profile ID and score on a tournament page.
If you allow notifications, your phone gives the app a notification token. If you are signed in, we store the token and your time zone with your profile. Only signed-in players get notifications from our server. A reminder that the app sets on your phone sends us nothing.
We use your time zone so that messages from us are never sent at night where you are. You get no more than three of them in a day. A message that another player sends you, such as a friend request or an invite, doesn't count towards that limit and can arrive at any time. We keep a record of who each of our messages went to and when.
Apple delivers notifications to iPhones and iPads. Google's Firebase Cloud Messaging delivers them to Android phones. A message can include another player's name.
You can turn off some kinds of message in the app's Settings and every kind in your phone's settings.
Your phone's app store handles every payment. We never receive your payment details.
When you buy something or get a refund, Apple tells our server which product it was, its price and currency, and when it happened. If you were signed in to Game Center when you bought it, we match the purchase to your profile and keep it with your name. Purchase records have no end date. Deleting your profile does not remove them.
The iPhone and Android apps tell Google Firebase Analytics about a few things you do in the game. Finishing a game is one of them. Firebase also records some events of its own. One of them is the app being opened for the first time. Firebase collects these with an app instance identifier created on your device. Neither app collects your advertising identifier for analytics. This lets us see how many people who install the game go on to play it. It also lets us measure our ad campaigns. We do not sell or share this data for anyone else's advertising. Google's handling of it is governed by Google's Privacy Policy at https://policies.google.com/privacy.
The iPhone and Android apps use Meta's software kit to measure the ads we run on Facebook and Instagram. It tells Meta when the app is installed or opened. It also sends Meta the events that the apps report to Firebase. Meta receives these with technical information about your device, such as its model and system version. Neither app sends Meta your advertising identifier. The iPhone app never asks for permission to track you. Meta's handling of this data is governed by Meta's Privacy Policy at https://www.facebook.com/privacy/policy/.
Clag shows ads. Some are ads you choose to watch in return for something in the game. The ads come from Google AdMob and are non-personalised. To serve the ads, prevent fraud and limit how often you see them, Google's advertising software collects technical data such as a device identifier, how you interact with ads and diagnostic information. This data is not linked to your identity and is not used to track you across other apps or websites. Google's handling of it is governed by Google's Privacy Policy at https://policies.google.com/privacy.
Apple's Game Center and Google Play Games also hold your Clag achievements and scores. Apple's handling of them is governed by Apple's Privacy Policy at https://www.apple.com/legal/privacy/. Google's is governed by Google's Privacy Policy at https://policies.google.com/privacy.
Our server keeps logs for 30 days to help us find problems. A log line can include the first part of a profile ID, the Game Center or Play Games name of a player who connects, or the internet address of a sign-in that failed.
Our server and its storage run on Microsoft Azure.
You can delete your online profile in the app's Settings. This removes your profile, your rated-game history, your leaderboard entries, your friends and pending friend requests, your notification tokens and your season progress. It also takes you out of any tournament you have signed up for. In a tournament that has already started, you are shown as "Deleted player".
These things are kept after you delete your profile:
If you are still signed in to Game Center or Play Games, Clag makes a new, empty profile the next time it opens. To stop this, sign out of Game Center or Play Games before you open Clag again.
You can also email us to ask for your information to be removed. We complete these requests within 30 days.
Clag is rated 12+. We do not knowingly collect personal information from children. The ads Clag shows are non-personalised.
We may update this policy from time to time. The latest version will always be available at this address.
