Deal Radar — Checkout Profiles

Store buyer/shipping profiles and autofill Amazon, Walmart, and Best Buy checkout forms in one click.

Deal Radar makes retailer checkout faster without ever taking the last step for you. Save one or more shipping profiles — name, email, phone, and address — and fill Amazon, Walmart, and Best Buy checkout forms with a single click. You still review every field and place the order yourself. WHAT IT DOES - Store multiple checkout profiles (e.g. different shipping addresses or contact emails) locally in your browser. - One-click autofill of the shipping/contact fields on Amazon, Walmart, and Best Buy checkout and address pages. - An optional encrypted login vault: keep retailer sign-in credentials protected by a master password and fill a sign-in page on demand. Filling a login is always a manual button click. WHAT IT NEVER DOES - Never submits a form, clicks "Place order", or presses Enter for you. Every purchase and every sign-in is completed by you. - Never stores, reads, or fills payment-card fields. Payment stays 100% manual. - Never sends your data anywhere. There are no accounts, no servers, no analytics, and no telemetry. Everything stays on your device. HOW YOUR DATA IS PROTECTED - Shipping profiles are stored locally in the browser's extension storage. - Login credentials are encrypted with AES-GCM-256 using a key derived from your master password (PBKDF2-HMAC-SHA256, 600,000 iterations). The unlocked key lives only in session memory and is discarded when the browser session ends — it is never written to disk in plaintext, and the master password is never stored at all. Deal Radar is fill-only by design: it speeds up data entry, and you stay in control of every submit.
