3. General information and mandatory disclosures

Data protection

The operator of these pages takes the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.

When you use this website, various personal data may be collected. Personal data is data by which you can be personally identified. This privacy policy explains what data we collect and what we use it for. It also explains how and for what purpose this happens.

We point out that data transmission on the internet (e.g. when communicating by email) may be subject to security gaps. Complete protection of data against access by third parties is not possible.

Notice concerning the responsible party

The party responsible for data processing on this website is:

Nils Hillmann
Rabienstr. 63
27726 Worpswede, Germany

Phone: +49 152 29536729
Email: dfir@89deg.com

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

Storage duration

Unless a more specific storage period has been stated within this privacy policy, your personal data will remain with us until the purpose for the data processing no longer applies. If you assert a legitimate request for erasure or withdraw 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 the latter case, the data will be deleted once those reasons no longer apply.

General information on the legal bases for data processing on this website

If you have consented to data processing, we process your personal data on the basis of Art. 6 (1)(a) GDPR or Art. 9 (2)(a) GDPR, insofar as special categories of data pursuant to Art. 9 (1) GDPR are processed. In the case of express consent to the transfer of personal data to third countries, data processing is also carried out on the basis of Art. 49 (1)(a) GDPR. If you have consented to the storage of cookies or to access to information on your device (e.g. via device fingerprinting), data processing is additionally carried out on the basis of § 25 (1) TDDDG. Consent can be withdrawn at any time. If your data is required for the performance of a contract or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6 (1)(b) GDPR. Furthermore, we process your data where required to fulfil a legal obligation, on the basis of Art. 6 (1)(c) GDPR. Data processing may also be carried out on the basis of our legitimate interest pursuant to Art. 6 (1)(f) GDPR. Information on the legal bases relevant in each individual case is provided in the following paragraphs of this privacy policy.

Recipients of personal data

In the course of our business activities we work with various external parties. In some cases, this also requires the transfer of personal data to these external parties. We only pass on personal data to external parties if this is necessary in the context of contract fulfilment, if we are legally obliged to do so (e.g. passing on data to tax authorities), if we have a legitimate interest in the transfer pursuant to Art. 6 (1)(f) GDPR, or if another legal basis permits the data transfer. When using processors, we only pass on personal data on the basis of a valid data processing agreement. In the case of joint processing, a joint processing agreement is concluded.

Withdrawal of your consent to data processing

Many data processing operations are only possible with your express consent. You can withdraw consent you have already given at any time. The lawfulness of the data processing carried out up to the point of withdrawal remains unaffected by the withdrawal.

Right to object to data collection in special cases and to direct advertising (Art. 21 GDPR)

IF DATA PROCESSING IS CARRIED OUT ON THE BASIS OF ART. 6 (1)(E) OR (F) GDPR, YOU HAVE THE RIGHT TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA AT ANY TIME FOR REASONS ARISING FROM YOUR PARTICULAR SITUATION; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON WHICH PROCESSING IS BASED CAN BE FOUND IN THIS PRIVACY POLICY. IF YOU OBJECT, WE WILL NO LONGER PROCESS YOUR PERSONAL DATA CONCERNED UNLESS WE CAN DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING WHICH OVERRIDE YOUR INTERESTS, RIGHTS AND FREEDOMS, OR THE PROCESSING SERVES THE ASSERTION, EXERCISE OR DEFENCE OF LEGAL CLAIMS (OBJECTION PURSUANT TO ART. 21 (1) GDPR).

IF YOUR PERSONAL DATA IS PROCESSED FOR THE PURPOSE OF DIRECT ADVERTISING, YOU HAVE THE RIGHT TO OBJECT AT ANY TIME TO THE PROCESSING OF PERSONAL DATA CONCERNING YOU FOR THE PURPOSE OF SUCH ADVERTISING; THIS ALSO APPLIES TO PROFILING INSOFAR AS IT IS ASSOCIATED WITH SUCH DIRECT ADVERTISING. IF YOU OBJECT, YOUR PERSONAL DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR THE PURPOSE OF DIRECT ADVERTISING (OBJECTION PURSUANT TO ART. 21 (2) GDPR).

Right to lodge a complaint with the competent supervisory authority

In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the Member State of their habitual residence, their place of work or the place of the alleged violation. The right to lodge a complaint exists without prejudice to any other administrative or judicial remedies.

Right to data portability

You have the right to have data that we process automatically on the basis of your consent or in fulfilment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done to the extent technically feasible.

Access, rectification and erasure

Within the framework of the applicable statutory provisions, you have the right at any time to free information about your stored personal data, its origin and recipients and the purpose of the data processing and, if applicable, a right to rectification or erasure of this data. You can contact us at any time regarding this and any other questions on the subject of personal data.

Right to restriction of processing

You have the right to request the restriction of the processing of your personal data. You can contact us at any time for this purpose. The right to restriction of processing exists in the following cases:

If you have restricted the processing of your personal data, this data may — apart from its storage — only be processed with your consent or for the assertion, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of an important public interest of the European Union or a Member State.

SSL or TLS encryption

For security reasons and to protect the transmission of confidential content, such as inquiries you send to us as the site operator, this site uses SSL or TLS encryption. You can recognise an encrypted connection by the fact that the address line of the browser changes from “http://” to “https://” and by the padlock symbol in your browser line.

If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Objection to advertising emails

We hereby object to the use of contact data published within the framework of the legal notice (Imprint) obligation for sending unsolicited advertising and information materials. The operator of the pages expressly reserves the right to take legal action in the event of the unsolicited sending of advertising information, for example through spam emails.

4. Data collection on this website

Server log files

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

This data is not merged with other data sources.

The collection of this data is based on Art. 6 (1)(f) GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimisation of its website — for this purpose, the server log files must be collected.

Inquiry by email or telephone

If you contact us by email or telephone, your inquiry including all resulting personal data (name, inquiry) will be stored and processed by us for the purpose of handling your request. We do not pass on this data without your consent.

The processing of this data is based on Art. 6 (1)(b) GDPR if your inquiry is related to the fulfilment of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective handling of the inquiries addressed to us (Art. 6 (1)(f) GDPR) or on your consent (Art. 6 (1)(a) GDPR) if this has been requested; consent can be withdrawn at any time.

The data you send to us via contact inquiries will remain with us until you request its erasure, withdraw your consent to storage, or the purpose for data storage no longer applies (e.g. after your request has been fully processed). Mandatory statutory provisions — in particular statutory retention periods — remain unaffected.

Local storage (theme preference)

This website does not set any cookies for tracking or analytics. To remember your light/dark appearance preference, the site stores a single technical value (dfir-theme) in your browser’s local storage when you use the theme toggle. This value never leaves your device, is not transmitted to us or to any third party, and is used solely to display the site in your chosen theme. You can delete it at any time via your browser settings. Storage takes place at your request within the meaning of § 25 (2) TDDDG; the legal basis for any associated processing is Art. 6 (1)(f) GDPR (legitimate interest in a functional, user-friendly presentation).

5. Plugins and tools

Google Fonts (local hosting)

This site uses so-called Google Fonts, provided by Google, for the uniform display of typefaces. The Google Fonts are installed locally. No connection to Google servers takes place.

Further information on Google Fonts can be found at developers.google.com/fonts/faq and in Google’s privacy policy: policies.google.com/privacy.
