3IVIS GmbH ("us", "we", or "our") operates the quantsworld.com website (the Service). This page explains what data we collect, how we use it, and your rights under applicable law including the EU General Data Protection Regulation (GDPR).
Cookie consent
We do not set any non-essential cookies by default. When you first visit the site, a cookie consent dialog asks whether you accept analytics cookies. You can change your preference at any time via the Cookies link in the site footer. Your choice is stored in your browser's local storage; no consent cookie is itself sent to our servers.
Cookies and analytics
If you accept analytics cookies, we use Google Analytics (Google LLC) to collect anonymised usage data — pages visited, session duration, device type, and approximate location. This data helps us improve the site. If you decline, no analytics cookies are set and no data is sent to Google Analytics.
You can learn more about Google Analytics cookies here:
You can also opt out globally at any time using the Google Analytics opt-out browser add-on.
We also load fonts from Google Fonts (fonts.googleapis.com), which sends your IP address to Google's servers. This happens only if you accept analytics cookies; otherwise the site falls back to system fonts.
Log data
Our hosting provider (GitHub Pages) may automatically collect standard server log data, including IP address, browser type, and date/time of requests. This is processed for security and reliability purposes and is not linked to any personal identity by us.
Personal information
This site does not have user accounts, sign-up forms, or e-commerce. We do not actively collect names, email addresses, or payment information through the site itself. If you contact us by email, we will retain your contact details only for the purpose of responding to your query.
International data transfers
If you accept analytics cookies, your usage data is processed by Google LLC in the United States. Google LLC participates in the EU–U.S. Data Privacy Framework and processes this data under Standard Contractual Clauses approved by the European Commission, as described in Google's data processing terms. Our own company, 3IVIS GmbH, stores and processes any data you provide directly to us within Germany and the European Union.
Your rights (GDPR)
If you are in the European Economic Area, you have the right to access, correct, or erase personal data we hold about you, to restrict or object to its processing, and to data portability where applicable. To exercise any of these rights, contact us at [email protected]. You also have the right to lodge a complaint with your local data protection authority.
Links to other sites
Our Service may contain links to third-party sites not operated by us. We assume no responsibility for the content, privacy policies, or practices of any third-party sites. We encourage you to review their privacy policies before providing any personal information.
Children's privacy
This Service is not directed at children. We do not knowingly collect personal data from anyone under the age of 16. Under GDPR Article 8, processing personal data of a child under 16 (or the lower age permitted by member-state law, with a minimum of 13) requires verifiable parental consent. If you become aware that a child has provided us with personal information without appropriate consent, please contact us and we will take steps to remove it.
Changes to this policy
We may update this Privacy Policy from time to time. Changes are effective when posted on this page. We will update the "Last updated" date at the top of this page whenever changes are made.
