Everything you type on टंकण - lessons, speeds, accuracy, unlocked keys, settings, book positions - is stored only in your own browser's storage on your own device. It is not sent to us or to anyone else. Signing in or out never changes, uploads, or deletes it. Clearing your browser data erases it; use Settings → Export progress to move it to another device.
Sign-in is optional and handled by Firebase Authentication (a Google service). When you sign in, Google shares your basic Google profile - your name, email address and profile photo - with this site so it can show who is signed in. That sign-in record is stored by Google in the site's Firebase project, and it stays there after you sign out, until it is deleted (see below).
While you are signed in, Firebase stores your sign-in session in this browser's storage (IndexedDB/localStorage, under Firebase's own entries) so you stay signed in between visits. Signing out clears that session from this browser.
If you choose to save your progress to your account (the site asks first), a copy of your practice progress - lessons, speeds, unlocked keys and settings - is stored in the site's Firebase project under your account, so it survives a lost or changed device and can be restored when you sign in elsewhere. It updates as you practice, it is readable only by your signed-in account, and it is never public. Signing out stops further saving; the account copy remains until you ask for it to be deleted (below). Progress on a device where you never sign in still stays only in that browser, as described above.
That is all the site itself collects today. It does not collect your scores, typing data, location, or contacts. There is no advertising on the site today; if ads are added later (Google AdSense is planned), this page will be updated to say so before they go live. Nothing is sold to anyone. The only two ways information leaves your browser are the Google sign-in described above and the hosting provider's role described below.
The site is hosted by Cloudflare: its servers deliver the pages to your browser, which means your browser connects to Cloudflare to load the site. Cloudflare also loads its own Web Analytics beacon (a script from static.cloudflareinsights.com) into the pages it serves; Cloudflare describes this beacon as cookieless page-visit counting. That measurement is Cloudflare's, under Cloudflare's own terms - the site itself runs no analytics or tracking scripts of its own.
You can sign out at any time from Settings → Account; this ends the session in your browser. To have your sign-in record (name, email, profile photo) removed from the site's Firebase project entirely, email [email protected] and it will be deleted.
If features like score syncing or leaderboards are added later, this page will be updated to describe them before they launch, and anything new that leaves your device will be described here first.
