‍
We treat your personal data confidentially and in accordance with the applicable statutory data protection regulations and this Privacy Policy.

When you use this website, various personal data is collected. Personal data is any data that can be used to personally identify you.

This Privacy Policy explains which data we collect, how we use it, and for what purpose.

Please note that data transmission over the Internet (e.g., communication by email) may be subject to security vulnerabilities. Complete protection of data against access by third parties is not possible.

Note on the Data Controller
The data controller responsible for data processing on this website is:

Astair International GmbH
Hopfenstraße 1 D
24114 Kiel
Germany

‍The data controller is the natural or legal person who alone or jointly with others determines the purposes and means of processing personal data (e.g., names, email addresses, etc.).

Storage Period
Unless a more specific storage period is stated in this Privacy Policy, your personal data will remain with us until the purpose for processing no longer applies.

If you submit a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g., retention periods under tax or commercial law). In such cases, deletion will take place once those reasons no longer apply.

Information on Data Transfers to the United States and Other Third CountriesStorage Period
Among other things, we use tools provided by companies based in the United States or other countries that are not considered secure under data protection law.

When these tools are active, your personal data may be transferred to and processed in these third countries.

Please note that a level of data protection comparable to that of the European Union cannot be guaranteed in these countries.

For example, U.S. companies may be required to disclose personal data to security authorities without you being able to take legal action against such disclosure.

Therefore, it cannot be ruled out that U.S. authorities (e.g., intelligence agencies) may process, analyze, and permanently store your data located on U.S. servers for surveillance purposes.

We have no influence over these processing activities.

Revocation of Your Consent to Data Processing
Many data processing operations are only possible with your explicit consent.
You may revoke consent already granted at any time.
The legality of data processing carried out before the revocation remains unaffected by the revocation.

Right to Lodge a Complaint with a Supervisory Authority
In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, particularly in the Member State of their habitual residence, place of work, or the place of the alleged infringement.
‍
This right exists without prejudice to any other administrative or judicial remedies.

Right to Data Portability
You have the right to receive data that we process automatically on the basis of your consent or in fulfillment of a contract, in a commonly used, machine-readable format.

Where you request the direct transfer of data to another controller, this will only be done where technically feasible.

SSL and TLS Encryption
For security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the website operator, this website uses SSL or TLS encryption.

You can recognize an encrypted connection by the change in the browser’s address line from “http://” to “https://” and by the lock icon displayed in your browser.

When SSL or TLS encryption is activated, data transmitted to us cannot be read by third parties.

Information, Deletion, and Rectification
You have the right to receive data that we process automatically on the basis of your consent or in fulfillment of a contract, in a commonly used, machine-readable format.

Where you request the direct transfer of data to another controller, this will only be done where technically feasible.Within the framework of the applicable legal provisions, you have the right at any time to obtain free information about your stored personal data, its origin and recipients, and the purpose of the data processing. You may also have the right to request the correction or deletion of this data.

For this purpose, and for any further questions regarding personal data, you may contact us at any time.

Right to Restriction of ProcessingSSL and TLS Encryption
You have the right to request the restriction of the processing of your personal data. You may contact us at any time to exercise this right.

The right to restriction of processing applies in the following cases:

• If you contest the accuracy of your personal data stored by us, we generally require time to verify this. During the verification period, you have the right to request restriction of the processing of your personal data.
• If the processing of your personal data is or has been unlawful, you may request restriction of processing instead of deletion.
• If we no longer need your personal data, but you require it for the establishment, exercise, or defense of legal claims, you have the right to request restriction of processing instead of deletion.
• If you have objected pursuant to Article 21(1) GDPR, a balancing of interests between your interests and ours must be carried out. As long as it has not yet been determined whose interests prevail, you have the right to request restriction of the processing of your personal data.

If the processing of your personal data has been restricted, such data may—apart from being stored—only be processed with your consent, for the establishment, exercise, or defense of legal claims, for the protection of the rights of another natural or legal person, or for reasons of important public interest of the European Union or a Member State.
