Privacy policy

1. What this page covers

ROAS Calculator (roascalculator.page) is a small web tool run by an independent developer. This policy explains what the tool does with your files and the text you enter, what the website collects, and the choices you have. The short version: your files and text are processed inside your browser and are not uploaded to us or to anyone else.

2. Your files and the text you enter

Everything the tool does happens on your device, in your browser's memory. Files you open, text you paste and the results you download are never sent to our server. The server only delivers the pages, scripts and styles of the site. When you close the tab, the browser discards what it was working on. There are no accounts, no sign-up and no user profiles.

The numbers you type (ad spend, revenue, margin, prices, costs) are worked out by scripts in your browser and are never sent anywhere. What-if rows on the ROAS page and the last campaign on the CPM page are kept in your browser's local storage, so they are still there next time you open the page on this device; the "Clear rows" and "Clear" buttons remove them, and so does clearing your browser's site data. A product CSV you import is read in memory only: it is not saved, and it is gone when you close the tab or press "Close".

3. Cookies and analytics

The site uses Google Analytics 4 to count visits and to see which pages are useful. We never send Google Analytics the names or contents of your files, the text you enter or any part of the result. Advertising features are off for everyone, and we do not share analytics data with anyone else.

If you are in the European Economic Area, the United Kingdom or Switzerland, analytics cookies are off by default. Google works out your country from your IP address. Without your consent Google Analytics sets no cookies and stores no identifier on your device; the Google script still loads and can send Google a basic signal without a cookie: the page you opened, the time, your browser and device type, and your approximate location.

Everywhere else, analytics cookies are on by default. Google Analytics sets cookies named _ga and _ga_ followed by the property code, which can last up to two years, and processes the same technical data.

Your choice. If your browser's time zone is in Europe, the pages ask "Allow analytics cookies?" Yes and No take one click each. The answer is kept in your browser's local storage and applies to the whole site. You can change it any time with the "Cookie settings" link at the bottom of the tool, guide and privacy pages: choosing No removes the _ga cookies this site has set. You can also block cookies in your browser; the tool works the same without them.

Your browser connects to Google to load the analytics script, so Google sees your IP address. Google states that Google Analytics 4 uses it to estimate location and does not store it. Statistics are kept for 14 months.

4. Server logs

Like every website, our server writes a technical log of requests: the IP address, the time, the page address and the browser type. The site is served through Cloudflare, which also sees this traffic and protects the site from abuse. We use logs only to keep the site running and to look into errors; they are deleted after a short time.

5. Advertising

There are no ads on this site at the moment. If we add them later, this page will say so first, together with what the ad partner can see.

6. Children

The site is not aimed at children under 16 and knowingly collects no data from them.

7. Your rights

Depending on where you live, you may have the right to access, correct or delete personal data, to object to its processing, or to complain to a data protection authority. Because we hold no accounts and no files, in practice there is nothing about you to look up; analytics data is pseudonymous and is handled by Google under its own policy.

8. Contact

Questions about this policy: [email protected].

9. Changes

When the tool or the site changes in a way that matters for this policy, we update this page and the date at the top.
