Privacy-First

How Betty Works

Personalized shopping deals without the creepy tracking. No account needed. No data sold. Ever.

Our Privacy Commitment

We built Betty because we were tired of Big Tech selling our shopping data. Here's what makes us different:

What We Never Do

  • Sell your data — Your browsing history is never sold to advertisers or third parties
  • Require an account — No email, name, or personal info needed. You're an anonymous user
  • Track non-shopping sites — We only see visits to whitelisted e-commerce sites
  • Create a profile tied to you — Without account creation, there's no way to link data back to your identity

What We Do

  • Use data only for your recommendations — Your browsing history powers YOUR personalized deals, nothing else
  • Be transparent — You can see everything we know about you on the dashboard
  • Let you delete your data — Anytime, no questions asked
  • Keep it minimal — We collect only what's needed to recommend deals

How It Works

1

Install & Backfill

When you install the extension, it looks at your existing browser history for product pages on supported retailers. This gives Betty a head start understanding your preferences.

What's collected: URLs of product pages you've visited on shopping sites (Amazon, Nike, etc.)
2

Extract Products

For each product page, Betty extracts the product name, brand, price, and description. We only care about what products you looked at, not who you are.

Example: "Nike Air Max 90 - $130 - Running Shoes"
3

Build Your Taste Profile

Products are converted into mathematical vectors (embeddings) that capture their essence. Your recent browsing becomes a "taste vector" — a unique fingerprint of your preferences.

The math: Similar products have similar vectors, so we can find matches
4

Daily Drops

Every day at 6 PM, Betty reveals personalized deals on products similar to what you've browsed. These are products that are currently on sale and match your taste.

Why 6 PM? It creates a daily ritual instead of constant interruptions

What Data We Collect

Product Page URLs

URLs of product pages you visit on supported retailers. Not search pages, not account pages — only products.

Product Details

Name, brand, price, category, and description of products. This is public information on the webpage.

Timezone

Your timezone so we can deliver drops at 6 PM your local time. That's it.

What We Don't Collect

Your name or email
Payment or financial info
Non-shopping browsing history
Social media or personal data
Location or IP address
Cookies from other sites

No Account = No Identity

Here's the key: we don't require account creation. You get a random session ID when you install the extension. We literally cannot tie your shopping preferences back to you as a person because we don't know who you are.

Even if someone got our database, all they'd see is "Anonymous User #48291 likes sneakers and electronics" — with no way to connect that to a real person.

You Control Your Data

View Everything

The dashboard shows all the products and browsing data we have. Full transparency.

Delete Anytime

One click to delete all your data. Permanently. We don't keep backups of deleted data.

Why Betty Exists

The problem with shopping online today is that your data is the product. Companies track everything you do, build profiles, and sell them to advertisers. You have zero control.

Betty flips this: we use your browsing history to help you, not to sell ads. We find deals on products you'd actually want based on what you've looked at — then we get out of your way.

Your data powers YOUR recommendations. That's it. We don't sell it. We don't share it. We don't build profiles to target you with ads.
