Deal Radar — Checkout Pro

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.
