Last updated 1 November 2026.

The short version. Your world is built on your own side and nothing is uploaded unless you post a score card. A score card is counts and achievement ids: no chat titles, no links, no text you wrote. No ads, no cookies for tracking, nothing sold.

The skill and your world

The Claycay skill reads your Claude activity inside your own Claude session and writes one HTML page. That page and the activity it was made from stay with you.
Your world can show chat titles. If you plan to share it, build it with --redact to hide chat titles, chat links and task notes. The 📸 postcard never includes titles either way.
When it builds a world, the skill fetches claycay.com/skill-version.json to tell you if a newer version is out. That request carries no data about you beyond what any web request does (your IP address, which our host sees in its logs).
If you ask where you rank, the skill sends your score card to claycay.com/api/rank. It answers and stores nothing.
Quests you tick off and rivals you add are kept in your own browser (local storage), not on our servers.
ChatGPT, Gemini, Grok and DeepSeek. If you drop a data export on claycay.com/island, your browser opens it and builds the world right there. The file, your chats and their titles are never uploaded or stored. The same goes for a score card pasted there or an island link you open: the counts are read in your browser and nothing is saved. The island link you can copy holds counts and the name you typed, never titles.

What claycay.com stores

If you sign in (with Google), our auth provider keeps your Google account email, name and a user id. We use it so only you can update your spot on the board.
If you post a score card, we store the card (counts, achievement ids, XP per month, the date range), the display name you choose, your XP and level, and when you posted. The board is public: anyone can see your display name, level and XP. Pick a nickname if you prefer.
If you joined through an invite, we store which player invited you, so they get their reward.
Items you own (looks for your island) are stored against your user id.
If you joined the waitlist, we store your email and when you signed up, and use it only to tell you when that thing launches.
Downloads of the skill are counted per day as a single number. Nothing about who downloaded.

Analytics

The home page uses Cloudflare Web Analytics to count visits. It uses no cookies and doesn’t follow you across sites. Worlds and the skill have no analytics at all.

Who else is involved

Google Firebase hosts the site, sign-in and database (servers in the United States).
Cloudflare counts visits to the home page.
Pages load fonts from Google Fonts and the 3D engine from cdnjs, which see your IP address like any web request.

We don’t sell or share your data with anyone else.

Deleting your data

Email hello@claycay.com from the address you signed in with and we’ll remove your player entry, items, invites and sign-in account. To leave the waitlist, same address. Your world file is yours: delete it like any other file.

Changes

If this changes in a way that matters, we’ll update the date above and say so on the home page.
