?
Once an hour the extension loads parser settings for the site you open from our server — this lets us fix and update parsers without updating the extension itself. We count how many different browsers requested settings per day. No personal data, carts or price history reach us.
How it works
Shop as usual. Every time you open your cart, the extension remembers the prices. Check your cart every day or two, and each item will build up a price history.
Your data stays with you
No sign-up. Everything is stored locally in your browser: we don’t collect your browsing history and don’t share anything with third parties. You can limit the extension’s access to just the stores you use.
Your store isn’t supported?
Write to us, and we’ll add it in the next update.
