What we collect
BuyWise collects the product URLs you submit for analysis and the resulting analysis data. When you sign in with Google, we store your email address and a user identifier so we can track your usage quota. We do not sell your data to third parties.
How we use it
- To run fake-review analysis on product pages you visit
- To enforce free-tier usage limits (10 deep analyses per day)
- To cache analysis results so repeat lookups are fast
- To improve our detection models (aggregated and anonymised)
Cookies & analytics
We use PostHog for product analytics. PostHog may set cookies to track sessions. You can opt out by enabling "Do Not Track" in your browser. We do not use advertising cookies.
