This privacy policy explains what personal data is processed when you visit autocalco.org and what rights you have.
1. Controller
Autocalco. Email: contact@autocalco.org.
2. Calculator inputs
All calculations are performed locally in your browser. The values you enter are not transmitted to our server and are not stored.
3. Hosting and server logs
The website is hosted by Hostinger. When you visit a page, the server automatically records technical data (IP address, date and time, page requested, browser type, referrer) to deliver the site securely. These logs are kept for a short period and are not used to identify you. Legal basis: legitimate interest in the secure operation of the website (Art. 6(1)(f) GDPR).
4. Advertising (Google AdSense)
This website uses or may use Google AdSense, an advertising service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google and its partners may use cookies and similar technologies to show ads and measure their performance. Where required by law (for example in the EU, the UK and Switzerland), personalised ads are only shown after you give consent through the consent banner; you can change your choice at any time. More information: How Google uses information from sites that use its services. You can manage personalised advertising in your Google ad settings.
4a. Analytics (Google Tag Manager / Google Analytics)
We use Google Tag Manager and Google Analytics (Google Ireland Limited) to understand how visitors use the site, for example which calculators are used most. Google Analytics may set cookies and processes data such as pages viewed, device and approximate location; IP addresses are not stored in full. In the EEA, the UK and Switzerland, analytics and advertising cookies are only used after you consent (Google Consent Mode); without consent only cookieless, aggregated measurements are sent. You can withdraw consent at any time via the privacy settings link or your browser settings.
4b. Cookies and third parties
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this and/or other sites. You can opt out of personalised advertising in Google Ad Settings or at aboutads.info.
4c. Push notifications
If you click "Allow", your browser creates a push subscription (a technical address of your browser's push service). We store this address, your site language and the date of subscription on our own server to send you notifications about new calculators and guides, and we count whether a notification was displayed or clicked. We do not use third-party notification services. You can unsubscribe at any time in your browser's site settings; the subscription is then deleted from our list when the next notification fails.
5. Contact by email
If you email us, we use your message and email address only to answer you and delete them when they are no longer needed.
6. Your rights
Depending on where you live (for example under the GDPR, the Swiss Federal Act on Data Protection, Quebec's Law 25 or US state privacy laws), you may have the right to access, correct or delete your data, to restrict or object to processing, to data portability and to withdraw consent. You can also lodge a complaint with your data protection authority. To exercise your rights, contact contact@autocalco.org.
7. Changes
We may update this policy when our services change. The current version is always available on this page.
