Privacy

Short version: no cookies, no ads, no personal data, nothing to opt out of.

What we collect

• Anonymous pageviews. When a page loads, the browser sends us the page path, the referring site (if any), and a UTM source tag (if present). No cookies, no fingerprinting, no user or session identifiers, no IP address storage. We keep the country code supplied by our hosting provider.
• Outbound click counts. When you use a /go/ link to a software product, we record which product link was clicked and from which page — again with no identifier tied to you.
• Calculator inputs are never transmitted. All calculators run entirely in your browser.

Third parties

If you click through to a software vendor, their site sets its own cookies for affiliate attribution — that's between you and them, governed by their privacy policy. We receive aggregate conversion reports that contain no personal information.

Hosting: Vercel. Data storage: Supabase (EU region). Questions: privacy@rentformulas.com.
