Privacy policy

What is kept, and why

In your browser

• A random ID, created the first time you visit (ink_user_id). It identifies your practice history, not you.
• Your choice of language and of simplified or traditional script.
• Mixpanel's own 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. Ink a Day 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. Google gives us these when you sign 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 characters you wrote, how many strokes you missed, whether you asked to see the stroke order, how long each took, and on which days. We use it to schedule your reviews and count your streak.
• 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 characters finished and strokes missed, to understand what helps people learn 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. If you're signed in, Mixpanel also receives your name and email address, so we can connect a question you send us to what happened; our own statistics service doesn't. They go to:

• Mixpanel, an analytics service, which may process data in the United States;
• our own statistics service, which we run ourselves.

If you email us

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

Other services the site uses

Stroke data for each character is loaded from jsDelivr, a public content network. As with any website your browser fetches from, jsDelivr receives your IP address and browser details with each request. It does not receive your practice history or your ID.

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. If you do sign in, Google knows that you signed in to Ink a Day.

What we don't do

• We don't sell or rent your data.
• We don't use it for advertising, or share it with advertisers.
• We don't require your name or email to use the site; signing in is optional.

How long it's kept

Practice history is kept while Ink a Day 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 inkaday.com removes your ID and preferences 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. To find it, open your browser's developer tools on inkaday.com and look in local storage for ink_user_id. We'll send you a copy or delete it, as you ask.
• Limit analytics: there's no setting in Ink a Day 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

Ink a Day 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.
