Deal Radar — Checkout Profiles

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.
