Cookie Policy

A full list of every cookie used on this site — essential, analytics, and advertising — and how to manage them.

1. What Are Cookies?

Cookies are small text files that a website places on your device when you visit it. They are widely used to make websites work efficiently and to remember your preferences between visits.

This policy also covers browser localStorage — a similar mechanism that allows websites to store data on your device without an expiry date. Like cookies, localStorage data never leaves your device unless a website explicitly transmits it to a server. We do not.

2. Essential Cookies and Local Storage

These are always active because they are necessary for the website to function. They do not require your consent.

Name Provider Purpose Expiry
site_theme MiniBrainGames Stores your chosen colour theme (light or dark) so the correct theme loads on your next visit without flicker. 1 year
cookie_consent MiniBrainGames Stores your cookie consent choices so the banner is not shown on every page visit. 1 year
sudoku_bests MiniBrainGames (localStorage) Saves your best Sudoku completion times per difficulty. Never transmitted to any server. Until cleared
ms_bests MiniBrainGames (localStorage) Saves your best Minesweeper completion times per difficulty. Never transmitted to any server. Until cleared

3. Analytics Cookies (Google Analytics)

With your consent, we use Google Analytics to understand how visitors use MiniBrainGames — which games are most popular, session duration, device types, and approximate geographic region. This helps us improve the site. IP addresses are anonymised before storage. These cookies are only placed after you accept analytics cookies in the consent banner.

Name Provider Purpose Expiry
_ga Google Analytics Registers a unique ID used to generate statistical data about how visitors use the website. 2 years
_ga_* Google Analytics Used by Google Analytics 4 to persist session state and count page visits. 2 years
_gid Google Analytics Registers a unique ID used to generate statistical data about how visitors use the website. 24 hours

Data collected by Google Analytics is processed by Google LLC and may be transferred outside the EU. For more information see Google's Privacy Policy. You can opt out globally by installing the Google Analytics Opt-out Browser Add-on.

4. Advertising Cookies

To support the free operation of MiniBrainGames, the site may display advertisements served by third-party advertising networks such as Google AdSense. With your consent, these services place cookies on your device to show relevant ads based on your interests and to measure ad performance. Advertising scripts are loaded only after you accept advertising cookies in the consent banner.

Name Provider Purpose Expiry
IDE Google DoubleClick Used to register and report the website user's actions after viewing or clicking an advertisement, to measure effectiveness and show relevant ads. 1 year
test_cookie Google DoubleClick Used to check if the user's browser supports cookies. Session
ANID, NID Google Used by Google to remember your preferences and other information, and to show you personalised ads on Google services. 6–13 months

You can opt out of interest-based advertising at any time through Your Online Choices (EU) or AboutAds. Opting out does not remove ads — it means the ads shown will no longer be tailored to your interests.

When you first visit MiniBrainGames, a cookie consent banner is displayed. You can choose to accept or decline each category of non-essential cookies independently:

• Essential cookies — always active, cannot be declined (required for the website to function).
• Analytics cookies — accept or decline Google Analytics tracking.
• Advertising cookies — accept or decline personalised advertising.

Your choice is saved in the cookie_consent cookie for one year. You can change your preferences at any time by clicking "Cookie Settings" in the page footer — this reopens the consent panel and lets you update your choices. Withdrawing consent does not affect the lawfulness of processing that took place before withdrawal.

6. How to Manage and Delete Cookies

You can control cookies and localStorage through your browser settings. The exact steps vary by browser:

Google Chrome: Settings → Privacy and security → Clear browsing data → Cookies and other site data.

Mozilla Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data.

Microsoft Edge: Settings → Privacy, search, and services → Clear browsing data → Choose what to clear.

Safari: Preferences → Privacy → Manage Website Data → Remove.

Deleting the site_theme cookie will cause the website to revert to detecting your operating system's colour scheme preference on your next visit. Deleting localStorage will remove your saved best times from all games.

You can also block all cookies through your browser settings. Note that blocking the site_theme cookie means your theme preference will not be saved between visits, but all games will still function normally.

Essential cookies (site_theme, cookie_consent, localStorage items) — strictly necessary. These do not require consent under the ePrivacy Directive and GDPR Article 6(1)(b) because they are required to deliver features you have explicitly requested or to record your consent decision.

Analytics cookies (Google Analytics) — based on your consent (GDPR Article 6(1)(a)). These are only placed after you actively accept them in the consent banner.

Advertising cookies (Google AdSense / DoubleClick) — based on your consent (GDPR Article 6(1)(a)). These are only placed after you actively accept them in the consent banner.

8. Changes to This Policy

We may update this Cookie Policy if we change the technologies we use. The "Last updated" date at the top of this page will be revised accordingly. We encourage you to check this page from time to time, especially before any changes to our advertising setup.
