FAQ
Buy Fast is a free Chrome extension for Amazon, Flipkart, Myntra, and Ajio. It shows price history on listings and speeds up checkout during flash sales. Flip ON on a product page — checkout runs in about a second, and you confirm before anything ships.
Amazon.in, Flipkart, Myntra, and Ajio — on desktop Chrome (laptop or PC). Open this page on your computer to install. It does not run inside retailer mobile apps or on phone browsers.
Yes, completely free. No subscription, no premium tier, and no hidden charges. Install from the Chrome Web Store and use it on supported sites.
Buy Fast runs locally in your browser. We do not store payment card numbers, UPI credentials, or retailer passwords on our servers. Checkout assistance reads page elements on supported shopping sites only. You approve every order before it ships.
No. Buy Fast drives checkout to the confirmation step and stops there. You must review and approve every order — nothing ships automatically. If a legitimate checkout helper ever placed orders silently, that would be a red flag.
No. Payment preferences (COD, UPI, Net Banking) are saved in the extension on your device so checkout can run faster. We do not collect card numbers, CVV, or UPI PIN on our servers.
Chrome asks permission to run on supported shopping sites (Amazon, Flipkart, Myntra, Ajio). That lets Buy Fast read product pages for price history and assist checkout. It only activates on those domains — review the permissions prompt during install.
Buy Fast works on desktop Chrome — your laptop or PC. It is not available for retailer mobile apps or phone browsers. To install, open autobuyfast.in on a computer with Chrome.
Use the contact form and add your email. We reply within 24 hours for install issues, bugs, or feature requests.
