Your Data Is Yours. Here's How We Keep It That Way.
We know we're asking you to connect your grocery store account. That means trusting us with your purchase history — and we take that seriously.
Here's exactly what we access, what we store, and what we never do.
What We Access
When you connect your store account, CartSnitch uses an automated scraper to pull your purchase history from the store loyalty portal. This means we can see:
- What you bought — product names and quantities
- How much you paid — shelf prices at time of purchase
- When you bought it — purchase dates
We cannot see:
- Your store login credentials
- Payment method information
- Your physical location
What We Store
We store only the data we need to calculate unit prices and compare baskets:
- Product identifiers (names, sizes, categories)
- Shelf prices and unit prices
- Purchase frequency
- Your tracked products and alerts
We do not store:
- Your full purchase history indefinitely
- Payment information
- Personal identifying information beyond your email
What We Never Do
- We never sell your data. Your data is never a product. We don't license it, share it with third parties, or use it for advertising.
- We never see your login credentials. CartSnitch accesses your store loyalty portal through an automated scraper — we never have access to your store password.
- We never post to your social accounts or profile.
- We never use your purchase data for anything other than the CartSnitch service.
How We Use Your Data
We use your purchase data to:
- Calculate unit prices — so you can compare products fairly
- Detect shrinkflation — by monitoring when products you buy change in size or price
- Compare store prices — to show you where your total basket costs less
- Send you alerts — when products you track change in price or size
That's it.
Data Retention
- You can delete your account and all associated data at any time
- When you disconnect a store account, we remove the connection and stop accessing new data
- Historical data associated with your account can be deleted on request
Security
- All data is encrypted in transit and at rest
- CartSnitch accesses store loyalty portals using an automated scraper — we never see your store password
- Our team follows strict access controls — only the engineers who need your data to build the product can access it
Want to Disconnect?
You can disconnect your store account at any time:
- Go to Settings
- Select "Connected Accounts"
- Click "Disconnect" next to the store you want to remove
Disconnecting immediately stops us from accessing new data from that store.
