Privacy & cookies

Last updated 28 October 2026

Cyber-Jack is a small, independent UK software studio. The whole point of what we build is to respect your data: our apps are on-device first, there are no subscriptions harvesting your behaviour, and we do not sell your data. Our free browser games and the studio home page show a small number of Google ads to help pay for themselves; the apps do not. This page explains, in plain English, what happens on our websites and in our apps.

The short version

We use Google Analytics to count anonymous visits, but only if you say yes. If you decline, no analytics run at all.
The free games (games.cyber-jack.uk, Letterly, Cluster, Rankle) and the cyber-jack.uk home page show ads from Google AdSense. In the UK, the EEA and Switzerland, Google's consent message asks you first, and advertising cookies are only used if you agree. See Advertising below.
We do not sell your data, and the apps themselves carry no ads or advertising trackers.
Most of our apps keep your data on your own device. Where an app stores data on a server, its own privacy policy explains exactly what and why.

Cookies and similar technology on this website

Under UK law (PECR), we can only store or read non-essential information on your device with your consent. So:

Analytics (Google Analytics 4) - needs your consent. On pages without ads, our own small banner asks if you are happy with anonymous analytics; on pages that show ads, Google's consent message asks instead (so you are never asked twice). Nothing analytics-related loads until you agree. If you accept, Google Analytics counts your visit with your IP address anonymised; we use this only to understand roughly how many people use the site and which pages are popular. There are no advertising features, no Google Ads linking, and no cross-site profiling. You can change your mind at any time using the Cookie preferences link in the footer.
Advertising (Google AdSense) - needs your consent. See Advertising below.
Your consent choice - strictly necessary. We store your choice in your browser so we do not ask you on every page: a small cj_consent_v1 value in local storage for our own banner, and Google's consent cookies (such as FCCDCF and FCNEC, holding an IAB TCF consent string) for Google's consent message. These hold only your preferences, not tracking data.
Login sessions - strictly necessary. On apps where you log in (for example Inkframe), we set a secure session cookie after you sign in so the app knows it is you. This is required for the service to work and is set only once you choose to log in.

Advertising (Google AdSense)

The free games at games.cyber-jack.uk, letterly.cyber-jack.uk, cluster.cyber-jack.uk and rankle.cyber-jack.uk, and the cyber-jack.uk home page, carry Google AdSense code. The games show one ad on the results screen, never during a round; the games hub shows one at the foot of the page. Ads are how the games stay free.

Consent first. Visitors in the UK, the EEA and Switzerland see Google's consent message (a Google-certified consent tool using the IAB Transparency and Consent Framework) with Consent, Do not consent and Manage options. Google and its ad partners only store or read advertising cookies on your device if you agree.
If you agree, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to our sites and/or other sites on the internet. The full list of ad partners is in the consent message under Manage options.
If you do not agree, Google can only show limited ads, which do not use cookies or other local storage for advertising and are not personalised.
Change your mind at any time with the Cookie preferences link at the foot of the games and the home page, which reopens the consent message.
You can also opt out of personalised advertising across the web at Google's Ads Settings (and, for other ad companies, at youronlinechoices.eu).
How Google uses data when you use sites that carry its services: policies.google.com/technologies/partner-sites. Google's own privacy policy: policies.google.com/privacy.

Third parties that help run the sites

Google Fonts. Some pages load typefaces from Google's font service. To deliver a font, your browser contacts Google, which means your IP address is shared with Google for that request. No cookie is set by this. We are working to reduce reliance on third-party fonts over time.
Cloudflare. Our sites are served and protected by Cloudflare, which guards against abuse and attacks. Cloudflare may process connection metadata and set security tokens as part of keeping the sites available. This is a strictly-necessary security function.

The apps

Each app has its own privacy policy describing the data it handles:

Your rights

Under UK GDPR you can ask us what personal data we hold about you, ask us to correct or delete it, and object to certain processing. For website analytics there is no account or identifier that ties data to you personally, so there is usually nothing to retrieve, but you are always welcome to ask. To exercise any right, or if you are unhappy with how we have handled your data, email us at [email protected]. You also have the right to complain to the UK Information Commissioner's Office (ICO) at ico.org.uk.
