Privacy at WordCurious
The short version comes first. The full policy follows, written to be read.
Last updated November 13, 2026
The short version
No student accounts
Students play from a link or a six-digit code. They never sign up or sign in.
Nothing about students is saved
No names, emails, scores, voice recordings or photos. Results stay on the student’s screen.
No ads or trackers where children play
Games, tests, list pages and the join page load nothing from other companies.
Teachers share very little
Your email, your lists and your settings. Polar, our payment partner, handles card details.
We never sell data
Not teachers’ data, and not anyone else’s.
AI sees only your words
To write sentences and definitions, we send the words on your list and nothing else.

Forward the one-page summary to your principal or IT team. It covers what we collect, what we don’t, and who we work with.
The full policy
1. Who we are
WordCurious runs wordcurious.com. In this policy, “we” means WordCurious.com, India. You can reach us at hello@wordcurious.com.
2. Students
Students use WordCurious without an account. When a student opens a game or a test, we don’t ask for or store their name, email, scores, voice or photos. Answers are checked on the device, and the answers themselves aren’t kept.
We count anonymous totals for each list: how often it was played and, for each word, how many tries were right. A misspelling is counted only if it’s close to the real word, like “trane” for train; anything else is thrown away. Nothing is ever linked to a student. Pages children use don’t load ads, analytics, social buttons, embedded videos or fonts from other companies.
3. Teachers and parents
Accounts are for adults. When you sign up, we keep:
- your email address, so you can sign in
- your lists, folders and settings
- whether you’re on Free or Plus, which Polar tells us. We never see your card number
- messages you send us
- how you use the teacher pages and any errors they hit, so we can fix problems
If you choose Google sign-in, Google shares your email address and basic profile information with Supabase to create or sign in to your account. We use this information only for your WordCurious account and do not request access to Gmail, Drive or Classroom. Lists hold words, not student information. Please don’t type students’ names into a list.
4. Analytics choices
On adult marketing and adult tool pages, you can choose to allow Google Analytics. It uses cookies and standard browser information to measure page visits and general device information. We send public page paths and the referring website, without query strings, fragments, form contents, list words or account IDs. Advertising features and enhanced measurement are off.
Google Analytics never loads on student games, practice, ready-made lists, spelling tools, sign-in, teacher accounts, class mode or print pages. You can change your choice using Analytics preferences on an adult marketing or tool page. Choosing No thanks stops Analytics, clears its analytics cookies from this browser and reloads the page.
5. Pages with ads
Ads appear only on some tools for adults: the puzzle makers, the word tools and a few older articles. They never appear on list pages, games, tests or anywhere students play.
On those pages, Google AdSense may use cookies. Visitors in the EEA, the UK and Switzerland are asked for consent first. US visitors can opt out with “Your privacy choices” at the bottom of every page.

7. How long we keep data
We keep your account data while your account is open. A list you delete stays in Recently deleted for 30 days, so you can restore it, and then we erase it. When you delete your account, the app deletes your lists and settings as part of completing that request. Billing records are kept as long as tax law requires.
8. Your choices
You can download or delete your lists at any time, and delete your account from Settings. To ask what we hold about you, or to correct it, email hello@wordcurious.com.
9. Changes and contact
If we change this policy, we’ll update the date at the top. If a change matters for how we handle your data, we’ll email account holders first. Questions go to hello@wordcurious.com or Bhubaneswar, India.
