Cookie Policy
Last updated: September 14, 2026
Short version: KindLearn sets no cookies at all — not even essential ones. What is listed below is kept in your browser's storage instead. There are no advertising cookies, no tracking pixels and no third-party analytics of any kind, so no consent banner is required.
What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They help sites remember information about your visit — such as whether you are logged in. KindLearn uses localStorage and sessionStorage instead, browser storage that is not sent along with every request the way cookies are. Most of what we keep there never leaves your device. Three things are sent to our API: your sign-in token, to prove who you are; lesson results that could not be saved, once your connection works again; and a friend's invite code, if you signed in through an invite link.
What We Keep in Your Browser
| Name / Purpose | Duration | Provider | Type |
|---|---|---|---|
Sign-in token Keeps you signed in across page loads. Issued by KindLearn when you use a magic link. Stored in your browser, not in a cookie. | Up to 30 days | KindLearn (local storage) | Essential |
Theme preference Remembers whether you prefer light or dark mode. | Persistent (localStorage) | KindLearn (local) | Essential |
Language preference Stores your chosen UI language so the interface loads in the right language on return. | Persistent (localStorage) | KindLearn (local) | Essential |
Review schedule When each flashcard and vocabulary word is next due for review, per language. The XP you earn from reviews is saved to your account. | Persistent (localStorage) | KindLearn (local) | Essential |
Lesson in progress Where you are in a lesson, so you can resume after a reload. Not offered again after 24 hours. | Until the lesson is finished or another lesson replaces it (localStorage) | KindLearn (local) | Essential |
Unsaved lesson results Lesson results that could not reach our servers. They are sent to our API the next time you are signed in with a working connection, then removed. | Until saved (localStorage) | KindLearn (local, then our API) | Essential |
Kids Zone minutes Minutes used in the Kids Zone today on this device, for the optional daily time limit a parent can set. | Resets each day (localStorage) | KindLearn (local) | Essential |
Reminder time Only if you allow browser notifications: the time of your daily reminder, so it can be scheduled again on your next visit. | Persistent (localStorage) | KindLearn (local) | Your choice |
Prompts already seen Which one-time prompts you have dismissed or already seen, such as the notification prompt, the day 7 and day 30 cards and the certificate, so they are not shown again. | Persistent (localStorage) | KindLearn (local) | Your choice |
Invite code Only if you open a friend's invite link before signing in: holds the code until you finish signing in, then it is sent to our API to connect you with that friend. | Until you close the tab (sessionStorage) | KindLearn (local, then our API) | Essential |
Page to return to The page to open after you sign in. | Until you close the tab (sessionStorage) | KindLearn (local) | Essential |
Offline copy A copy of the home page, app icons and manifest, so the app can still open without a connection. Your account data is not in it. | Until replaced (service worker cache) | KindLearn (local) | Essential |
