Privacy Policy

Last updated: September 2026

ROAS Calculator ("this site") is a free browser-based tool for calculating Return on Ad Spend and related metrics.

What we don't collect

The calculator and campaign comparison table run entirely in your browser using JavaScript. The numbers you enter — ad spend, revenue, campaign labels, and so on — are never sent to, processed by, or stored on our servers.

Local storage

Your campaign comparison table is saved using your browser's local storage so it's still there the next time you visit this site on the same device and browser. This data stays on your device; we cannot see it, and clearing your browser data will remove it.

Server logs

Like most websites, our hosting infrastructure may keep standard server access logs (such as IP address, browser type, and requested page) for security and operational purposes. These logs are not used to identify individuals or to track behavior across sites.

Cookies & analytics

We use Google Analytics to understand how visitors use this site — things like which pages are viewed, how long people stay, and what device or browser they're using — so we can improve it. Google Analytics sets its own cookies to distinguish visitors and sessions, and collects information such as your approximate location, device and browser type, and pages visited. It does not receive the numbers you enter into the calculator, and does not receive your name, email, or any other information that could identify you personally. You can opt out using the Google Analytics Opt-out Browser Add-on, or by blocking cookies in your browser settings. See Google's Privacy Policy for how Google handles this data.

Advertising

We use Google AdSense to display ads on this site. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this site or other websites, and to measure ad performance. You can review or opt out of personalized advertising in Google's Ads Settings, or through www.aboutads.info/choices if you're outside a country that offers Ads Settings. See how Google uses information from sites that use its services for more detail.

Future changes

If this site adds further analytics or advertising in the future, this policy will be updated to describe what's collected and how it's used before that happens.
