Privacy Policy
Effective date: October 3, 2026
Local Practice Data
Android Prep stores your chapter progress, reviewed flashcards, and self-scored answers in your browser's local storage. Those values stay on your device unless you clear browser data.
Sign-In And Premium
Signing in with Google or an email link is only needed to start or restore a Premium subscription. Your email is used to identify the Premium account and is not shown in page content.
Analytics, Feedback, And Support
The site uses Trei web analytics for page and product usage. Feedback sent through trei.dev/feedback is handled by the shared Trei feedback backend with app/source context. For support or deletion questions, email contact.gangwar@gmail.com.
Delete Your Account
Signed in, open premium, then delete account, and confirm. Trei deletes your learning account data for every Trei prep site: your Premium entitlement, purchase-restore record, and any unfinished checkout. Progress this site saved in your browser is cleared and you are signed out; other Trei prep sites keep their own browser progress until you clear it there. Deleting does not cancel an active Premium renewal; email contact.gangwar@gmail.com to stop it. Invoices stay with Razorpay or Dodo Payments, and Trei keeps only payment and subscription reference numbers, with no name or email, for tax and accounting as the law requires. Your Google or email sign-in is shared with other Trei products and is not removed; email us to remove it or to ask for deletion without signing in.
Advertising
Free mode uses Google AdSense advertising units to fund the site. Google may use cookies or similar technologies to serve and measure ads. Premium no-ads users do not load AdSense after an active Premium restore succeeds; Premium removes ads only and does not lock any chapter or flashcard.
Children's Privacy
Android Prep is not directed at children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has given us information, email contact.gangwar@gmail.com and we will delete it.
