What we use, what we do not.

These are stored on your device and are always on:

• aitwin-analytics-optout. A small entry in localStorage, set only if you turn analytics off in Analytics settings. It is the only record of that choice; without it we cannot remember you opted out.
• aitwin-lang-banner-dismissed. A small entry in localStorage that remembers you closed the language banner at the top of the page. Set only if you dismiss it, and used only to stop the banner from reappearing.
• aitwin-language-vote. A small entry in localStorage, set only if you send us a language preference from the languages page. It stops the form from reappearing on your next visit.
• aitwin.guides.assistantTab. A small entry in localStorage that remembers which assistant tab you last viewed in the guides, so the guide opens on your choice. It holds a short label and nothing else.
• aitwin.guides.sevenDayProgress. A small entry in localStorage that remembers which items you have ticked on the first-seven-days checklist, so your progress is kept between visits. It holds a list of ticked items and nothing else.
• Supabase auth session. If we ever add sign-in to this site, a first-party localStorage key holds your session token. It is not populated today because there is no sign-in surface here.

None of the entries above is shared with anyone. None identifies you. All are cleared if you clear your browser storage for this site. Strictly necessary storage does not require consent under UK PECR, but we list it for transparency.

We use Plausible Analytics to understand which pages people read. Plausible is a privacy-friendly analytics provider based in the European Union. It sets no cookies, writes nothing to your device, and does not identify individual visitors. It uses aggregate, hashed signals that reset daily. UK PECR governs storing or accessing information on your device. Plausible does neither, so no consent banner is required for it and we do not show one. If you would rather not be counted at all, open Analytics settings in the footer and turn it off. Your choice is remembered in a small entry on your device, listed above. We do not use third-party advertising cookies, tracking pixels, profiling cookies, or cross-site tracking. We do not use Google Analytics, Facebook Pixel, or similar.

Open Analytics settings in the footer at any time to turn analytics off or back on. You can also clear your choice by clearing your browser storage for this site.

Most browsers also let you block all cookies, accept only first-party cookies, or clear stored data on close. Blocking strictly necessary storage will cause the language banner to reappear on every visit, but the site will still work.

We update this page when we add or remove any technology that fits into one of the categories above. The last-updated date at the top reflects the most recent change. We will not add new tracking silently.
