This site runs on localStorage, not tracking. Here is the full inventory.
The inventory
| Key | Type | Purpose | Lifetime |
|---|---|---|---|
| wia-theme | localStorage | Remembers dark/light preference | Until cleared |
| wia-admin | sessionStorage | Demo admin session flag | Tab session |
| wia-consent | localStorage | Remembers your analytics / advertising choice | Until cleared |
| wia-recent-searches | localStorage | Your last few search terms, so the search box can offer them again | Until cleared |
| wia-cache-v2 | localStorage | Cached copies of entry pages you have already opened, so revisiting one is instant instead of re-fetching it. Holds published content only — nothing about you. | Until cleared |
| wia-logged-topics | localStorage | Which not-found search terms this browser has already submitted to the research queue, so the same term is not sent twice | Until cleared |
| wia-admin-overlay | localStorage | Draft edits held in the admin demo, so they survive a reload | Until cleared |
| wia-cube-streak-v1 wia-cipher-streak wia-showroom-1982-v1 | localStorage | Progress in the three puzzles and games: how many days you have solved in the Daily Scramble and the Daily Cipher, your current and best runs, any banked freezes, and which of the eight Showroom endings you have seen. Kept so a returning visitor is credited for what they have already done. Never sent anywhere. | Until cleared |
| wmx_best, wmx_bestd wmx_days, wmx_parts wmx_reveal | localStorage | Progress in the Watch Labs: your best regulation result and the date you set it, the days you have visited, which of the eighteen movement parts you have identified, and whether today's hidden defect has been revealed. | Until cleared |
| _ga (future) | cookie | Aggregate analytics — disabled by default | 24 months if enabled |
| Google advertising (for example __gads, __gpi) | cookie | Set by Google, not by us, to serve and measure ads and to prevent fraud and abuse. Personalised advertising is off unless you opt in. | Per Google's own retention |
Analytics storage is only set after you opt in. Advertising cookies are set by Google as soon as an ad is served — non-personalised ads still need them for frequency capping and fraud prevention — but personalised advertising only happens if you opt in. You can change your choice at any time, and clearing site data in your browser removes everything we store.
