1. Privacy at a glance

General information

The following notes give a simple overview of what happens to your personal data when you visit this website. Personal data is any data by which you can be personally identified. Detailed information on data protection can be found in our privacy policy set out below.

Data collection on this website

Who is responsible for data collection on this website?

Data on this website is processed by the website operator. You can find the operator's contact details in the section “Information on the controller” in this privacy policy.

How do we collect your data?

On the one hand, your data is collected when you provide it to us. This may, for example, be data you enter into a contact form.

Other data is collected automatically, or with your consent, by our IT systems when you visit the website. This is mainly technical data (e.g. internet browser, operating system or time of the page request). This data is collected automatically as soon as you enter this website.

What do we use your data for?

Part of the data is collected to ensure that the website is provided without errors. Other data may be used to analyse your user behaviour. Where contracts can be concluded or initiated via the website, the data transmitted is also processed for contract offers, orders or other order enquiries.

What rights do you have regarding your data?

You have the right at any time to receive information free of charge about the origin, recipients and purpose of your stored personal data. You also have the right to request the correction or deletion of this data. If you have given consent to data processing, you can revoke this consent at any time with effect for the future. You also have the right, under certain circumstances, to request the restriction of the processing of your personal data. Furthermore, you have the right to lodge a complaint with the competent supervisory authority.

You can contact us at any time about this and any other questions on data protection.

2. Hosting

We host the content of our website with the following provider:

External hosting

This website is hosted externally. The personal data collected on this website is stored on the servers of the host(s). This may include, in particular, IP addresses, contact requests, meta and communication data, contract data, contact details, names, website access and other data generated via a website.

External hosting is carried out for the purpose of fulfilling contracts with our potential and existing customers (Art. 6(1)(b) GDPR) and in the interest of secure, fast and efficient provision of our online offering by a professional provider (Art. 6(1)(f) GDPR). Where corresponding consent has been requested, processing takes place exclusively on the basis of Art. 6(1)(a) GDPR and § 25(1) TDDDG, insofar as the consent covers the storage of cookies or access to information on the user's device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time.

Our host(s) will only process your data to the extent necessary to fulfil their service obligations and will follow our instructions regarding this data.

We use the following host:

Netlify, Inc.
512 2nd Street, Suite 200
San Francisco, CA 94107, USA

Data processing agreement

We have concluded a data processing agreement (DPA) for the use of the service named above. This is a contract required by data protection law which ensures that the provider processes our website visitors' personal data only in accordance with our instructions and in compliance with the GDPR.

3. General information and mandatory disclosures

Data protection

The operators of these pages take 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 is 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 is done.

Please note that data transmission over the internet (e.g. when communicating by email) can have security gaps. Complete protection of data against access by third parties is not possible.

Information on the controller

The controller responsible for data processing on this website is:

Oleg Bondarenko
Olaf Böttcher
Am Queckenberg 21
38120 Braunschweig

Phone: +49 1514 0127220
Email: info@olafboettcher.de

The controller is the natural or legal person who, alone or jointly with others, decides on 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 the data processing no longer applies. If you make a justified 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 the latter case, the data will be deleted once these 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, where special categories of data under Art. 9(1) GDPR are processed, Art. 9(2)(a) GDPR. In the case of express consent to the transfer of personal data to third countries, data processing is also based on 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 based on § 25(1) TDDDG. Consent can be revoked at any time. If your data is required to fulfil a contract or to carry out pre-contractual measures, we process your data on the basis of Art. 6(1)(b) GDPR. Furthermore, we process your data on the basis of Art. 6(1)(c) GDPR where this is necessary to fulfil a legal obligation. Data processing may also be based on our legitimate interest under Art. 6(1)(f) GDPR. The legal bases relevant in each individual case are set out 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 to fulfil a contract, if we are legally obliged to do so (e.g. passing on data to tax authorities), if we have a legitimate interest in passing it on under Art. 6(1)(f) GDPR, or if another legal basis permits the disclosure. When using processors, we only pass on our customers' personal data on the basis of a valid data processing agreement. In the case of joint processing, a joint processing agreement is concluded.

Transfers to third countries

Netlify, Resend and Umami are based in the USA or process data there. This website's server functions run in a US data centre; Resend stores the content of the emails sent in the USA; the analytics data is processed on servers in the USA and the EU.

The transfer is based on the data processing agreements concluded with the providers, including the European Commission's standard contractual clauses agreed therein (Art. 46(2)(c) GDPR).

Many data processing operations are only possible with your express consent. You can revoke consent you have already given at any time. The lawfulness of the data processing carried out until the revocation remains unaffected by the revocation.

IF DATA PROCESSING IS BASED ON ART. 6(1)(E) OR (F) GDPR, YOU HAVE THE RIGHT AT ANY TIME TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA ON GROUNDS RELATING TO YOUR PARTICULAR SITUATION; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE LEGAL BASIS ON WHICH ANY 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 ESTABLISHMENT, EXERCISE OR DEFENCE OF LEGAL CLAIMS (OBJECTION UNDER ART. 21(1) GDPR).

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

Right to lodge a complaint with the competent supervisory authority

In the event of breaches 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 breach. The right to lodge a complaint is without prejudice to any other administrative or judicial remedies.

The supervisory authority responsible for us is:

Der Landesbeauftragte für den Datenschutz Niedersachsen (State Commissioner for Data Protection of Lower Saxony)
Prinzenstraße 5
30159 Hannover
Phone: 0511 120-4500
www.lfd.niedersachsen.de

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 insofar as it is technically feasible.

Information, correction and deletion

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, where applicable, a right to correction or deletion of this data. You can contact us at any time about this and any other questions on 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 about this at any time. The right to restriction of processing exists in the following cases:

If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.
If the processing of your personal data was or is unlawful, you can request the restriction of data processing instead of deletion.
If we no longer need your personal data but you need it to exercise, defend or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion.
If you have lodged an objection under Art. 21(1) GDPR, your interests and ours must be weighed against each other. As long as it has not been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.

If you have restricted the processing of your personal data, this data – apart from its storage – may only be processed with your consent, for the establishment, exercise or defence 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 of a Member State.

SSL/TLS encryption

For security reasons and to protect the transmission of confidential content, such as orders or enquiries that you send to us as the site operator, this site uses SSL/TLS encryption. You can recognise an encrypted connection by the browser's address bar changing from “http://” to “https://” and by the lock symbol in your browser bar.

If SSL/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 the contact details published under the legal notice obligation for sending advertising and information material that has not been expressly requested. The operators of the pages expressly reserve the right to take legal action in the event of unsolicited advertising information being sent, for example by spam email.

4. Data collection on this website

Cookies

Our website uses so-called “cookies”. Cookies are small data packets and do not cause any damage to your device. They are stored on your device either temporarily for the duration of a session (session cookies) or permanently (persistent cookies). Session cookies are deleted automatically at the end of your visit. Persistent cookies remain stored on your device until you delete them yourself or your web browser deletes them automatically.

Cookies can come from us (first-party cookies) or from third-party companies (so-called third-party cookies). Third-party cookies enable certain services of third-party companies to be integrated into websites (e.g. cookies for processing payment services).

Cookies have various functions. Many cookies are technically necessary, as certain website functions would not work without them (e.g. the shopping basket function or the display of videos). Other cookies may be used to analyse user behaviour or for advertising purposes.

Cookies that are required to carry out the electronic communication process, to provide certain functions you have requested (e.g. the shopping basket function) or to optimise the website (e.g. cookies for measuring the web audience) (necessary cookies) are stored on the basis of Art. 6(1)(f) GDPR, unless another legal basis is stated. The website operator has a legitimate interest in storing necessary cookies for the technically error-free and optimised provision of its services. Where consent to the storage of cookies and similar recognition technologies has been requested, processing takes place exclusively on the basis of this consent (Art. 6(1)(a) GDPR and § 25(1) TDDDG); consent can be revoked at any time.

You can set your browser so that you are informed about cookies being set and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when the browser is closed. If cookies are deactivated, the functionality of this website may be limited.

This website stores only two pieces of information on your device:

Language setting: if you open the website in a language other than the one your browser prefers, that language is stored in the NEXT_LOCALE cookie so the website stays in that language on later visits. The cookie contains only the language code (e.g. “de”) and no identifier by which you could be recognised. It is deleted when you close your browser.
Colour scheme: if you switch between the light and dark design, your choice is stored in your browser's local storage (localStorage). This information is not transmitted to the server and remains stored until you delete it in your browser.

Both are strictly necessary to provide the functions you requested (§ 25(2) no. 2 TDDDG). No consent is required for this; a cookie banner is therefore not used.

Server log files

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

browser type and browser version
operating system used
referrer URL
host name of the accessing computer
time of the server request
IP address

This data is not merged with other data sources.

This data is collected on the basis of 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 recorded.

Contact form

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you provided there, will be stored by us for the purpose of processing the enquiry and in case of follow-up questions. We do not pass on this data without your consent.

This data is processed on the basis of Art. 6(1)(b) GDPR if your enquiry is related to the fulfilment of a contract or is necessary to carry out pre-contractual measures. In all other cases, processing is based on our legitimate interest in effectively processing the enquiries 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 revoked at any time.

The data you enter in the contact form will remain with us until you ask us to delete it, revoke your consent to its storage or the purpose for storing the data no longer applies (e.g. after your enquiry has been processed). Mandatory statutory provisions – in particular retention periods – remain unaffected. As a rule, we delete enquiries that did not lead to an order six months after the last message.

Protection of the contact form against abuse

To limit the number of enquiries per unit of time, your IP address is held briefly in the working memory of the server function. It is not stored permanently. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in preventing automated abuse).

Email delivery via Resend

We use the Resend service to send the messages received via the contact form. The provider is Plus Five Five, Inc., 2261 Market Street #5039, San Francisco, CA 94114, USA.

The details from the form are delivered by this website's server function as an email via Resend to our mailbox. In doing so, Resend processes the content of the message, your name and email address as well as the sender and recipient addresses, time and delivery status. The data is stored in the USA; Resend keeps it for 30 days.

The legal basis is Art. 6(1)(b) GDPR if your enquiry is related to the initiation or fulfilment of a contract, and otherwise Art. 6(1)(f) GDPR (legitimate interest in the reliable delivery of enquiries).

Resend acts as a processor; the data processing agreement forms part of the service's terms of use.

Emails you write to us directly are not transmitted via Resend.

Email mailbox at Zoho Mail

Messages from the contact form and emails you write to us directly are stored in our mailbox at Zoho Mail. The provider for users in the EU is Zoho Corporation GmbH, II. Hagen 7, 45127 Essen, Germany. The data is stored in data centres within the EU.

The complete content of the message and the email header data are processed. Zoho carries out automated virus and spam checks.

The legal basis is Art. 6(1)(b) or (f) GDPR, as for the contact form. Zoho acts as a processor.

Enquiries by email or telephone

If you contact us by email or telephone, your enquiry including all resulting personal data (name, enquiry) 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 data you send us via contact enquiries will remain with us until you ask us to delete it, revoke your consent to its storage or the purpose for storing the data no longer applies (e.g. after your request has been processed). Mandatory statutory provisions – in particular statutory retention periods – remain unaffected.

Fonts

This website's fonts are delivered from the same server as the website itself. When a page is requested, no connection is established to Google Fonts, Adobe Fonts or any other external font provider. To that extent, no data is transmitted to third parties.

5. Analytics tools

Umami Analytics

This website uses the web analytics service Umami Cloud. The provider is Umami Software, Inc., 28 Geary St, Suite 650 #243, San Francisco, CA, USA.

Umami collects aggregated access statistics: the page visited (URL and page title), referring page, country of origin, browser, device and operating system type, screen resolution, browser language setting and the time spent on a page.

No cookies are set. To distinguish visits, Umami creates an encrypted, irreversible checksum from your IP address and your browser identifier (user agent) using a regularly changing key. Your IP address itself is not stored. We are unable to identify individual visitors.

When a page is loaded, the script only checks whether you have opted out of being counted in your browser's local storage (entry “umami.disabled”). Beyond that, no information is stored on or read from your device.

The legal basis is Art. 6(1)(f) GDPR. We have a legitimate interest in understanding which content on our website is in demand in order to improve our offering.

Processing takes place on servers in the USA and the EU. Umami in turn uses sub-processors, including for hosting, content delivery and database operation.

Umami acts as a processor; the data processing agreement forms part of the service's terms of use.
