Privacy Policy
MerchMargin ("we," "us," or "our") is a free web-based calculator tool operated under the Vanilabs brand. This policy explains what information we collect, how we use it, and your rights.
Information We Collect
MerchMargin is a client-side calculator. All calculations happen in your browser — no input data (prices, product types, sales figures) is transmitted to our servers or stored anywhere.
We may collect the following through third-party services:
- Usage analytics — page views, session duration, and browser/device type via Google Analytics 4 (GA4)
- Advertising data — ad impressions and clicks via Google AdSense
- Technical logs — IP addresses and request metadata via our hosting provider (Cloudflare)
Google AdSense Disclosure
MerchMargin displays advertisements served by Google AdSense. Google uses cookies and tracking technologies to serve ads based on your prior visits to this website and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
Google Analytics
We use Google Analytics 4 to understand how visitors use this site. GA4 collects anonymized data such as pages viewed and session duration. It does not collect personally identifiable information. You can opt out by installing the Google Analytics Opt-out Browser Add-on.
Cookies
MerchMargin itself does not set any first-party cookies. Cookies may be set by Google AdSense and Google Analytics as described above. You can control cookies through your browser settings or a browser extension such as uBlock Origin.
How We Use Your Information
- To understand site traffic and improve the tool
- To display relevant advertising that supports free access to this tool
- To maintain the security and performance of our hosting infrastructure
Data Sharing
We do not sell your personal information. We do not share your data with any third parties beyond the analytics and advertising services described above (Google Analytics and Google AdSense), and our hosting provider (Cloudflare). Each of these providers has their own privacy policy governing their use of your data.
