Who we are
Cornerleap is operated by Ducat Digital Ltd, a company registered in England and Wales (company number 17336739), registered office 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. We are the controller of the data described here. Write to us at privacy@ducatdigital.com.
The short version
You play without an account. We do not ask for your name or email, we set no advertising or tracking cookies, and we do not sell or share data for advertising.
What we collect
- Aggregate usage. We use Vercel's cookieless Web Analytics to count page views (the page, referring site, country, device and browser type, and the source tag on links we share, such as
?ref=forum) and anonymous game events: that a game started or was resumed, how it ended, which settings it used, and which buttons were pressed. None of this is tied to you, uses cookies or follows you to other sites. - Error reports. When the game breaks, Sentry receives the error, the page path, your browser type and the last few actions on the page (such as which control was pressed), so we can fix it. We switch off IP addresses, cookies and query strings in these reports.
- Server logs. Like any website, our host processes your IP address and browser details to deliver pages and protect the service. We do not use these logs to identify you.
Our lawful basis for analytics and error reports is our legitimate interest in running and improving the game, with no personal profile built from either.
What we keep in your browser
Only what a feature you use needs. You can clear it at any time in your browser settings.
cornerleap:game:v1(local storage): your current game and its settings, so a reload does not lose it.cornerleap:theme(local storage): the light or dark theme, when you pick one instead of following your device.NEXT_LOCALE(cookie, 1 year): the language you picked in the language switcher.
Sub-processors
These providers handle data on our behalf. The bracket says where.
- Vercel (EU edge for European traffic; server code in Frankfurt): hosting and content delivery, plus Vercel Web Analytics: cookieless, aggregate page views (page, referring site, country, device and browser type) and anonymous game events.
- Sentry (Germany, EU): error reports when the game breaks: the error, the page path, browser type and the last few actions on the page (such as which control was pressed). No IP address, cookies or query strings.
International transfers
Both providers are US-headquartered companies, including where they keep data in a European region. When data is transferred outside the UK or the EEA, we rely on Standard Contractual Clauses / the UK Addendum and the providers' own data-protection programmes. Ask us for copies of the safeguards.
Children
The game is for all ages. Because there are no accounts and we collect no personal data on purpose, a child can play without giving us anything about themselves.
Your rights
Under UK and EU data-protection law you can ask what we hold about you, and ask us to correct or delete it. Because we hold nothing tied to a person, there is usually nothing to return, but write to us and we will check. You can also complain to the Information Commissioner's Office or, in the EU, your national authority. We would rather you write to us first.
