Privacy Policy

1) Preamble

Welcome to the website of Optimax Energy! We place great importance on the protection of your data and the preservation of your privacy. Here, we would like to explain what data we process, when, for what purpose, and on what legal basis. This is to help you understand how our offered services operate and how the protection of your personal data is ensured.

Personal data, according to Article 4 (1) of the GDPR, encompasses all information related to an identified or identifiable natural person. An individual is considered identifiable if they can be directly or indirectly identified. More information on this can be found in Article 4 (1) of the GDPR.

Where we reference our legitimate interest or that of a third party (Article 6 (1) (f) GDPR) as the legal basis for processing personal data, you have a right to object as per Article 21 GDPR. Under Article 21 GDPR, you have the right to:

Object at any time to the processing of personal data. If you do, we will no longer process the personal data for direct marketing purposes or associated profiling.

Object to the processing of your personal data for reasons related to your specific situation, especially for processing that is carried out for scientific or historical research purposes, or statistical purposes as per Article 89(1) of the GDPR, unless it is necessary for a task carried out in the public interest (refer to Article 21 (6) GDPR).

To maintain clarity in our privacy statement, we refer to information and privacy notices on external websites via links at various points (also see the section "Social Networks & External Links" in this privacy policy). We aim to keep these links current. However, due to the constant updates of websites, it's possible that some links may not function correctly. If you encounter such a link, we would appreciate it if you could inform us so we can update to the current link.

3) Log-Files

Each time you access our website, our system automatically collects data and information from your device's system and stores it in server log files. This data relates to an identified or identifiable natural person (i.e., website visitor) and is automatically transmitted by your browser when you access our website. The data collected includes:

  • Time of access to our website (request to the server of the host provider),

  • URL of the website from which you accessed our site,

  • Operating system you are using,

  • Type and version of your browser,

  • Your computer's IP address masked (the last octet is nullified).

The purpose of this processing is to make our website accessible from your device and to enable a correct display of our website on your device or in your browser. Additionally, the data helps us optimize our website and ensure the security of our systems. These data are not evaluated for marketing purposes.

The legal basis for processing is Article 6 (1) (f) GDPR. We have a legitimate interest in presenting you with a website optimized for your browser and enabling communication between our server and your device. Processing your IP address is particularly necessary for this.

4) Cookies

On our website, we use cookies, which are text files stored on your device to make the use of a website more convenient or to recognize the user's device and save settings or similar information. Cookies can store inputs and settings on a website, so you don't have to re-enter or adjust them every time you visit a website anew. Cookies contain a so-called Cookie-ID, which enables the association of the device in which the cookie is stored.

Cookies assist us in making our online offering user-friendly and tailored. We use both our own cookies and third-party cookies. You can configure the setting of cookies at any time.

In your browser settings, you can restrict or completely prevent the setting of cookies. You can also activate the automatic deletion of cookies when closing the browser window.

5) Information on Google Services

On our website, we use various services provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google may collect and process information (including personal data) through these services, and there's a possibility that this information may be transferred to a server in a third country.

The transfer to the USA depends on the function in which personal data is transmitted. We may transfer data to Google in the USA for further use. Currently, there is no adequacy decision according to Article 45 of the GDPR. However, the transfer may be based on standard contractual clauses. Google has committed to comply with the standard contractual clauses for the transfer of personal data to third countries under Directive 95/46/EC.

We do not control the data Google actually collects and processes. Google states that the following information (including personal data) can be processed:

  • Log data (especially IP address)

  • Location-related information

  • Unique application numbers

  • Cookies and similar technologies

If you are logged into your Google account, depending on your account settings, Google may add processed information to your account and treat it as personal data. You can prevent this direct addition by logging out of your Google account or adjusting the relevant account settings.

Furthermore, you can change your cookie settings (e.g., delete, block cookies, etc.). More information is available under "5) Cookies".

6) Google Analytics

We use Google Analytics, a web analysis service provided by Google Ireland Limited, on our website. Google Analytics uses "cookies", text files stored on your device, to analyze your use of the websites you visit. It may also use Web Beacons to evaluate visitor traffic. The data generated by cookies and Web Beacons about your use of our website (including your IP address) are transmitted to, and stored by, Google, possibly in the USA or other third countries. Google may share this information with its partners.

We use Google Analytics with IP anonymization ("anonymize IP") activated. This means your IP address is truncated by Google within the EU or EEA states. Only in exceptional cases is the full IP address sent to a Google server in the USA and truncated there.

The legal basis for processing data collected with consent is our legitimate interest under Art. 6 (1) (f) GDPR, to prove the consent you provided for the measurement process (Art. 7 (1) GDPR).

You can prevent data collection by Web Beacons by downloading and installing an add-on for your browser from this link:

Further, you can prevent cookie installation through your browser settings, but this may limit the functionality of our website.

Processed information is stored as long as necessary for the intended purpose or as required by law.
