1. What this website stores
Our own code sets no cookies. It uses browser local storage for three preferences that never leave your device:
| Item | Purpose | Lasts |
|---|---|---|
blueburp-theme | Remembers a light or dark theme you picked with the header button. Not set while you follow your device setting. | Until you switch back to "system" or clear site data. |
blueburp-consent | Remembers whether you allowed or declined analytics so we do not ask on every page. | 12 months, then we ask again. |
blueburp-2048-best | Your best score in the in-browser 2048 demo. | Until you clear site data. |
2. Google Analytics cookies
With your permission, Google Analytics 4 sets first-party cookies to tell returning visitors from new ones and to group page views into sessions. They are set only after you choose "Allow analytics".
| Cookie | Purpose | Lasts |
|---|---|---|
_ga | Random identifier for your browser. | 2 years |
_ga_* | Keeps the current session state for this property. | 2 years |
Google Signals and advertising features are off, so these cookies are not used for ads. The privacy policy explains what Google receives.
3. Form protection
The contact page loads Cloudflare Turnstile to tell people from bots. Turnstile runs inside its own frame and may use browser features and technical signals to make that decision. It is configured without "pre-clearance", so it does not set the cf_clearance cookie on our site. Cloudflare's processing is described in its privacy policy.
4. Your controls
- Change your analytics choice any time: use the "Privacy choices" link in the footer or .
- Theme: the header button cycles system → light → dark. Choosing "system" removes the saved preference.
- Clear everything: your browser's site-data settings remove all items above and any Google cookies.
- Block cookies in your browser and the site still works; it just cannot remember your choices.
5. Our games
Games are not websites and do not use browser cookies. Ads in our games use the Android advertising ID and related identifiers, described in the privacy policy along with the controls Android gives you.
6. Changes and contact
We update this page whenever the site's storage or providers change. Questions go through the contact form.
