Privacy Policy

Last updated: 19 September 2026

Compacy is a geography game available on the web at compacy.com and as an app for Android and iOS. This page explains what the game stores, what it does not, and how to have your data removed. There is no account, no sign-up, and no email address is ever required to play.

What is stored

Data	Why	Where
A random player ID (a UUID generated on your device)	To keep your streak, atlas progress and leaderboard entry apart from other players	Your device, and our server once you submit a result
Username, if you choose one	To show you on the leaderboards. Optional — the game is fully playable without it	Our server
Game results: streak, score, time taken, cities answered correctly	Leaderboards, your atlas, and statistics about which city pairs players find hardest	Our server
Language choice, sound setting, your own progress	So the game works the way you left it	Your device only (browser local storage)
Notification token, only if you allow notifications in the app	To send occasional reminders about the daily challenge	Our server and Google Firebase

What is not stored

• No name, email address, phone number or postal address
• No location data — the game never asks for your position
• No contacts, photos, files or device identifiers beyond what is listed above
• No payment data — the game is free

Analytics

The website uses privacy-friendly traffic measurement provided by Cloudflare, which counts page views and referrers without cookies and without tracking individuals across sites. If additional analytics are ever enabled on the website, you will be asked for consent first and may decline. The apps do not include web analytics.

Advertising

The apps may show advertisements served by Google AdMob. When ads are active, Google may process your device's advertising identifier to select and measure ads, as described in Google's privacy policy. On iOS you are asked for permission before any tracking takes place, and declining does not affect the game. On the website, advertising is off unless you accept the cookie notice.

Who else sees the data

• Leaderboards are public: if you choose a username, it is visible to other players together with your score. Choose a nickname rather than your real name.
• Our hosting provider stores the data on our behalf.
• Google Firebase delivers notifications, and Google AdMob delivers ads when they are enabled.
• Nothing is sold, and nothing is shared for purposes other than running the game.

How long it is kept

Game results are kept for as long as the leaderboards exist. A username is released if the account behind it has no completed games or has not been used for 60 days. Notification tokens are deleted automatically once they stop working, for example after you uninstall the app.

Children

Compacy is suitable for all ages and is not directed at children under 13 in particular. It asks for no personal information, so a child can play without providing any. If you are a parent and believe a username identifies your child, contact us and we will remove it.

Your choices

• Delete your local progress: clear site data in your browser, or uninstall the app. This removes your player ID from the device.
• Delete your server data: write to the address below with your username and we will remove the account and its results.
• Notifications: turn them off at any time in your device settings.
• Ads and cookies on the website: decline the cookie notice, or clear site data to be asked again.

Changes

If this policy changes, the date at the top of this page changes with it. Significant changes will also be announced inside the game.
