What we currently use
The site currently sets no advertising or analytics cookies. Applications use browser localStorage to remember language and save demo settings or work. LocalStorage is not a cookie and is not automatically sent with each server request, but it is still storage on your device.
These functions preserve your language choice and work rather than track you across websites. Pages can be viewed with storage blocked, but settings or experiments may not persist.
Local storage overview
| Data / key | Purpose | Retention |
|---|---|---|
explonio-language | Manually selected language of the gallery and demos; demos use it to open in the right language. | Until deleted. |
| Demo languages | atomika-language, chaos-language, elektrolab-language, galton-language, lrc-language, optika-language, orbit-language, orbitarium-language, projektil-language, sfraktaly-language, terra-lang and thermolab-language. | Until deleted. |
| Saved experiments | elektrolab-v1, lever-lab-v1, logic-lab.project.v2 (including possible .recovery), lrc-lab-workspace-v3, optika-scene, orbit-experiment. May also contain language or display settings. | Until deleted or overwritten by a new save. |
The relevant application on this website stores these items. They have no automatic expiry; your browser may clear them according to its own rules. Server access logs are not cookies; see our Privacy policy.
Removing stored data
Open your browser’s site data settings and clear data for the Explonio domain. This also removes language preferences and saved experiments; export important work first. You can also block storage for this site. Exact controls depend on your browser.
Future advertising cookies and consent
Google AdSense is not connected yet. Before enabling it, we will identify advertising partners, technologies, purposes and retention periods and introduce appropriate consent management. Technologies requiring consent will stay off until you actively consent. Refusal will be as easy as acceptance, and a persistent settings option will allow you to change or withdraw consent later.
Non-personalised ads do not automatically mean no cookies or no consent requirement. Continuing to browse or closing a consent dialog will not count as consent. Refusal will not restrict access to the demos.
See our Privacy policy and Google’s information about data use for more on future Google processing.
