Privacy policy
Last updated October 2, 2026
You can practise letters, numbers and punctuation without an account; the word and Grade 2 decks need a Google sign-in. If you sign in with Google, we keep your name, email address and profile picture so your progress follows you between devices. We don't sell your data or use it for advertising.
In your browser
- A random ID, created the first time you visit (
braille_user_id). It identifies your practice history, not you. - Whether you last chose Read or Write.
- 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. Braille 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. 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 letters and words you practised, how many tries each took, whether you asked to see the answer or skipped, how long it took, and on which days. We use it to schedule your reviews and count your streak.
Analytics
We record which pages are visited and how practice goes, such as items answered and answers revealed, 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; our own statistics service doesn't. They go to Mixpanel, which may process data in the United States, and to our own statistics service.
Other services
- 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.
What we don't do
- We don't sell or rent your data, or use it for advertising.
- We don't require your name or email to practise letters, numbers and punctuation.
How long we keep it
Practice history is kept while Braille 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
- Start fresh: without an account, clearing your browser's site data for brailleaday.com removes your ID from this device, and your old history is no longer linked to you.
- Sign out at any time from the home page.
- 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 brailleaday.com, under
braille_user_id). - Limit analytics: there's no setting in Braille a Day to turn analytics off yet; a content blocker that blocks Mixpanel will stop it being sent there.
Children
Braille 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.
