Cookies Policy
Minimal data, maximal transparency. We use strictly necessary cookies to keep you safe and analytics only when you agree
This Cookie Policy explains how Abstract Technology GmbH ("we", "us", "Abstract") uses cookies and similar technologies on the website abstract-technology.de and on our subdomains. It supplements, and should be read together with, our Privacy Policy.
This document forms part of our broader data-protection framework. For information on how we process personal data more generally — including legal bases, retention periods, and your rights — please consult our Privacy Policy.
1. What are cookies?
Cookies are small text files that a website places on your device (computer, tablet, or smartphone) when you visit it. They are widely used to make websites work efficiently and provide information to the owners. Similar technologies — such as pixel tags, web beacons, local storage, and session storage — perform comparable functions and are covered by this policy.
- First-party cookies: Set by the website you are visiting.
- Third-party cookies: Set by embedded services (e.g., analytics or video providers).
- Session cookies: Deleted at the end of your browsing session.
- Persistent cookies: Remain on your device for a defined period.
2. Legal Basis
In the EU and Germany, cookie usage is regulated by the GDPR and the TDDDG (formerly TTDSG). We distinguish between two categories:
- Strictly necessary cookies: Essential for the website to operate or ensure security. No consent is required for these, but we inform you about them here.
- All other cookies: Used only after you have given explicit consent through our cookie banner. You may withdraw consent at any time via the "Cookie settings" in the website footer.
