Your progress, XP, streak, badges, daily power-up and any code you save in a sandbox are written to localStorage in your own browser. That data never leaves your device — there is no endpoint for it to be sent to. Clearing your site data erases it permanently, and we cannot restore it, because we never had a copy.
Privacy
The whole policyWe do not collect anything, because there is nothing here that
could collect it. No account, no cookie, no analytics script, no server that logs what you read.
What is stored, and where
Cookies
None. The site sets no cookies of any kind, so there is no cookie banner to dismiss.
Analytics
None. No Google Analytics, no Plausible, no pixel, no beacon, no server-side request logging that we control or read.
Third parties
Exactly one: the lettering is loaded from Google Fonts
(fonts.googleapis.com and fonts.gstatic.com). Requesting a font file exposes your
IP address to Google, as any request to any server does. If that matters to you, blocking those two hosts
leaves the site fully functional — it simply falls back to a system font.
Your web host will keep its own standard server logs. If you self-host this site, that is between you and your host.
Children
The site is suitable for all ages and collects no personal information from anyone, including children. There is no registration, so no age gate is required or possible.
Changes
If this ever stops being true — if analytics or accounts are ever added — this page will say so plainly before the change ships, not after.
