Privacy Policy

For transparency and for compliance reviewers, here is exactly what happens:

1. You add a product URL to your account.
2. On a tier-based schedule, Dipper retrieves the public page content — directly via a server request, or, for sites that block automated access, through a third-party scraping API that returns the rendered public HTML. Dipper does not log in, bypass paywalls, or access non-public content.
3. The retrieved page content is sent to our AI provider (Anthropic) to extract structured fields (title, price, currency, availability). Your data is not used to train AI models.
4. We store the extracted values and a timestamped price history.
5. When your alert rules are met, we notify you by email and in the app.

• Account: your email address, a hashed password, and an optional name.
• Tracked content: the product URLs you add and the product data and price history retrieved from them.
• Usage: counters (e.g. checks performed, Smart Track evaluations) used to enforce plan limits.
• Billing (if you subscribe): a Stripe customer and subscription identifier and status. Card details are handled entirely by Stripe — Dipper never sees or stores your card number.
• Technical: a single authentication cookie (a signed session token) and standard server logs.

Dipper relies on these providers to run the service:

• Anthropic — AI extraction of product details.
• Vercel — application hosting.
• Neon / PostgreSQL — database hosting.
• ScrapingBee — retrieving pages from sites that block automated access.
• Stripe — payment processing.
• Email/SMTP provider — delivering your alert emails.
