What we keep on your device, what is optional, and how to clear it. Last updated 19 September 2026.
Fernlantern uses local storage rather than cookies for nearly everything. Local storage works like a cookie but is never attached to requests — it stays on your device. UK rules under PECR treat the two the same, so consent is asked for anything not strictly necessary.
| Key | Purpose | Lifetime |
|---|---|---|
jadewave.v1 | Balance, stake, level, XP, statistics and settings | Until cleared |
jadewave.age | Your 18+ confirmation | Until cleared |
jadewave.cookie | Your cookie choice | Until cleared |
These cannot be disabled while using the site, because without them the game cannot remember a single spin. You can delete them from your browser whenever you like.
"Accept all" permits aggregate, non-identifying usage measurement: pages opened, games played. It informs what we build next, is never used for advertising, never shared with gambling operators and never tied to anything identifying. "Essential only" sets none of it.
Typefaces come from Google Fonts, so that request reaches Google and reveals your IP address and browser, as any web request does. No cookie is set by us in the process, and no other third-party tag, pixel or advertising network runs on Fernlantern.
Clearing this site's data also wipes your balance, level and statistics. There is no backup, so you would restart with 30,000 coins.
The Privacy Policy covers how this fits UK GDPR and what rights you have.
No account, no card, no download. Twenty-five lines and as long as you want.
Play Wild BloomFernlantern is for grown-ups. There is no money in the game and no prize at the end of it, but the mechanics are casino mechanics, so we ask before you come in.
