Know Ball? is a daily football puzzle game. This policy explains what we store about you, why, and how to get a copy or have it deleted. It is written to be read, not to be survived.
You can play without an account and without telling us anything. If you do that, we store a random identifier in your browser so your streak survives a refresh — nothing that identifies you. If you sign in, we also store your email address. We show adverts on the results and account screens — never during a game — and if you are in the UK or EU you get asked first. We do not sell anything to anybody, and there is a button on your account page that deletes the lot.
Know Ball? is run by Nathan Stowe-Morgans. For anything in this policy, including access and deletion requests, contact [email protected]. We are the data controller for the personal data described here.
A random ID in a cookie, created the first time you play. It links you to your own streak and scores. It is not shared, and it tells us nothing about you.
Lawful basis: Legitimate interests — the game does not work without it
Only if you choose to sign in. Used to send your login link and to attach your scores to you rather than to a browser.
Lawful basis: Contract — you asked us to keep your scores
Which puzzles you played, how many links you used, misses, hints, time taken, and the route you found. This is your score history, and in aggregate it produces the community percentages shown on the results screen.
Lawful basis: Legitimate interests — it is the product
Which screens you opened, which games you started, your guesses, hints, completions and shares. Recorded on our own servers and linked to your device identifier once you have played. We use it to see whether the games are worth continuing and which puzzles are too hard — never to build a profile of you, and never shared with anyone.
Lawful basis: Legitimate interests — knowing whether the thing works
Our hosting providers record IP addresses and request details for security and reliability. We do not use these to build a profile of you.
Lawful basis: Legitimate interests — keeping the service up and secure
That is the complete list. We do not store your name, your location, your contacts, or anything from other sites.
Two of ours, both strictly necessary:
We use no analytics cookies at all. Google's adverts may set their own cookies, but only on the screens that carry an advert and only if you consent — see below.
We do measure how the games are used, but no cookie is set for it and no outside company is involved: the counting happens on our own servers, and it is attached to the kb_device identifier you already have for your streak. If you have never played, nothing that is recorded identifies you at all — an arrival is counted without an identifier of any kind.
Adverts pay for the game. Where they appear is a deliberate decision, so it is worth stating exactly:
You can change or withdraw your choice at any time from the link in the consent form's footer. Google's own explanation of how it uses advertising data is at policies.google.com.
We use a small number of providers to run the service. They process data on our instructions and are not permitted to use it for their own purposes.
Some of these are US companies operating EU/UK infrastructure; where data leaves the UK it is covered by the standard contractual clauses those providers offer. We do not sell personal data, and we never will — there is no version of this game that is improved by it.
Under UK GDPR you can ask for a copy of your data, correct it, have it deleted, object to how we use it, or complain to the regulator. Two of those are buttons rather than emails:
One deliberate exception, stated plainly: when you delete your account we keep your past results in the community statistics, with nothing identifying attached. Those numbers are what other players see on the results screen, and removing them would quietly rewrite other people's statistics. They cannot be traced back to you.
For anything else, email [email protected]. If you are unhappy with how we have handled it you can complain to the Information Commissioner's Office at ico.org.uk.
The game is suitable for all ages, but accounts are intended for users aged 13 and over. If you believe a younger child has created an account, email us and we will remove it.
Player and club facts are drawn from public sources. That data is about footballers, not about you, and is not personal data of our players.
If this policy changes in a way that affects what we do with your data, we will say so in the app rather than quietly updating the date at the top.
