Privacy policy

What is kept, and why

In your browser

• A random ID, created the first time you visit (cluecatch_user_id). It identifies your practice history, not you.
• Identifiers for the analytics described below.
• If you sign in: a sign-in token, and your name, email address and picture, so the page knows it's you.

These are kept in your browser's local storage. Clue Catch doesn't use advertising cookies.

On our server

• Your account, if you sign in with Google: your Google account ID, name, email address and profile picture, and when you last signed in. We never see your Google password or anything else in your Google account. Sign-in sessions are stored only as one-way hashes.
• Practice history, stored against your random ID, or your account's if you sign in: which kinds of detail you practised, how many of each you got right, and on which days. We use it to schedule your reviews and count your streak. Your individual answers and the pictures you saw are not stored.
• Battles, if you create or play one: its settings, and each player's score and time. Anyone who opens a battle's link and signs in sees the first name and Google profile picture of everyone who played it. The creator's first name, the battle's title and a blurred preview image are shown to anyone the link is shared with, including in chat apps' link previews.
• Server logs: like most websites, our servers record requests, such as the page, the time, your IP address and your browser. We use them to keep the site running and secure.

Usage analytics

We record which pages are visited and how practice goes, such as pictures studied, questions answered and whether they were right, to understand what helps and to fix what doesn't. These records include your random ID, the page, your browser and device type, and your IP address, from which an approximate location may be derived. They go to our own statistics service and to Mixpanel, which may process data in the United States. If you're signed in, Mixpanel also receives your name and email address; our own statistics service doesn't.

If you email us

We keep your message and email address only to reply to you.

Other services the site uses

• Signing in uses Google. The home page loads Google's sign-in button, so Google receives your IP address and browser details when you visit it, whether or not you sign in.

How long it's kept

Practice history is kept while Clue Catch runs, so your reviews and streak keep working, unless you ask us to delete it. Analytics and server logs are kept only as long as they're useful for understanding and running the site.

Your choices and rights

• Start fresh: without an account, clearing your browser's site data for cluecatch.com removes your ID from this device, and your old history is no longer linked to you.
• Delete your account: email [email protected] from the address you signed in with. We'll delete your account and its practice history.
• See or delete your history: signed in, email [email protected] from your account's address. Without an account, email us your ID (in your browser's local storage for cluecatch.com, under cluecatch_user_id).
• Limit analytics: there's no setting in Clue Catch to turn analytics off yet; a content blocker that blocks Mixpanel will stop it being sent there.

Depending on where you live, you may have further rights, such as to object to how your data is used, or to complain to a data protection authority. Email us and we'll help.

Children

Clue Catch is not directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child has sent us personal information, email [email protected] and we'll delete it.

Changes to this policy

If what we keep or how we use it changes, we'll update this page and the date at the top.
