1. Information we collect
- Information you give us: if you use our contact form or email us, we receive your name, email address and the content of your message. If you subscribe to our newsletter, we receive your email address.
- Information collected automatically: like most websites, our servers and analytics tools collect technical data such as your IP address, browser type, device, pages visited, time spent on pages and the referring website.
- Calculators: the numbers you enter in our calculators are processed in your browser and are not stored by us.

We and our partners use cookies and similar technologies to operate the site, understand how it is used and show advertising. You can control cookies through your browser settings and, where required by law, through the consent banner shown on our site.
3. Advertising (Google AdSense)
We use Google AdSense to display ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to our site and/or other sites on the internet.
You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising by visiting www.aboutads.info. Learn more about how Google uses information from sites that use its services.

5. How we use information
We use information to operate and improve the site, respond to your messages, send newsletters you asked for, measure traffic, show ads, and protect the site against fraud and abuse. We do not sell your personal information for money.

We share information only with service providers that help us run the site, such as our hosting provider (Hostinger), analytics (Google Analytics), advertising (Google AdSense) and email tools, and when required by law.
7. Your privacy rights
- US residents: depending on your state (for example California, Colorado, Connecticut, Virginia and others), you may have the right to know what personal information we collect, to request deletion or correction, and to opt out of the “sale” or “sharing” of personal information for targeted advertising. You can use the privacy choices link on our site or email us at hello@quarterlo.com. We will not discriminate against you for exercising these rights.
- Visitors from the EEA, UK and Switzerland: you have the right to access, correct, delete or restrict the use of your personal data, to object to processing, to data portability, and to withdraw consent at any time. We rely on your consent for advertising and analytics cookies, collected through our consent banner.

We keep contact messages and newsletter data only as long as needed for the purpose they were collected for, or as required by law.
