Privacy policy

Last updated: 17 August 2026

1. Privacy at a glance

General information

The following information provides a straightforward 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. For detailed information, please read the full privacy policy below.

Who is responsible for collecting data on this website?

Data on this website is processed by the site operator. You will find their contact details under “Information on the controller” in this policy and in the imprint.

How do we collect your data?

Some data is collected because you give it to us – for example when you send us an e-mail or call us.

Other data is collected automatically or with your consent by our IT systems when you visit the website. This is primarily technical data such as your browser, operating system or the time of the page view.

What do we use your data for?

Part of the data is collected to ensure the website is delivered without errors. Other data is used to understand how the website is used so that we can improve it.

What rights do you have regarding your data?

You have the right to obtain information about the origin, recipients and purpose of your stored personal data free of charge at any time. You also have the right to request that this data be corrected or deleted. If you have given consent to data processing, you can withdraw that consent at any time with effect for the future. You also have the right to request that the processing of your personal data be restricted under certain circumstances, and the right to lodge a complaint with the competent supervisory authority.

You can contact us at any time regarding this and any other questions about data protection using the address given in the imprint.

2. Hosting

Vercel

This website is hosted by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA (“Vercel”).

When you access this website, Vercel processes technical data required to deliver the pages. This may include your IP address, browser type and version, operating system, referrer URL and the time of access. This data may be transferred to Vercel servers in the USA.

Vercel is used on the basis of Art. 6 (1) (f) GDPR. We have a legitimate interest in this website being presented reliably, securely and quickly. Where consent has been requested, processing takes place exclusively on the basis of Art. 6 (1) (a) GDPR and § 25 (1) TDDDG; consent can be withdrawn at any time.

The transfer of data to the USA is based on the European Commission’s standard contractual clauses. You can find details in Vercel’s privacy policy: https://vercel.com/legal/privacy-policy

We have concluded a data processing agreement with Vercel. This is a contract required by data protection law which ensures that Vercel processes the personal data of our visitors only in accordance with our instructions and in compliance with the GDPR.

3. General information and mandatory disclosures

Data protection

We 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.

Please note that data transmission over the internet – for example when communicating by e-mail – can have security gaps. Complete protection of data against access by third parties is not possible.

Information on the controller

The controller for data processing on this website is:

Jonas Bayer (bavajo) Wertachtalstr. 45 86517 Wehringen Germany

Phone: +49 159 08636471 E-mail: mail@jonas-bayer.com

The controller is the natural or legal person who alone or jointly with others determines the purposes and means of the processing of personal data.

Storage period

Unless a more specific storage period is stated within this privacy policy, your personal data remains with us until the purpose for processing it no longer applies. If you submit a justified request for deletion or withdraw your consent, your data will be deleted unless we have other legally permissible reasons for storing it – such as retention periods under tax or commercial law. In the latter case, the data will be deleted once those reasons cease to apply.

General notes on the legal bases for processing

Where you have consented to processing, we process your personal data on the basis of Art. 6 (1) (a) GDPR, or Art. 9 (2) (a) GDPR if special categories of data are processed. In the case of explicit consent to the transfer of personal data to third countries, 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, processing additionally takes place on the basis of § 25 (1) TDDDG. Consent can be withdrawn at any time.

If data is required to fulfil a contract or to carry out pre-contractual measures, we process it on the basis of Art. 6 (1) (b) GDPR. We also process data where it is necessary to fulfil a legal obligation under Art. 6 (1) (c) GDPR, or on the basis of our legitimate interests under Art. 6 (1) (f) GDPR. The legal basis that applies in each individual case is stated in the relevant sections 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 requires personal data to be passed on to them. We only pass on personal data where this is necessary to fulfil a contract, where we are legally obliged to do so, where we have your consent, or where we have a legitimate interest under Art. 6 (1) (f) GDPR and no overriding interests of yours stand in the way. Where we commission processors, we conclude a data processing agreement with them in accordance with Art. 28 GDPR.

The specific services we use are named in this policy: Vercel (hosting and analytics) and Google (tag management and analytics).

Note on data transfers to the USA

Some of the services we use are operated by companies based in the USA or process data there. Where personal data is transferred to the USA, we base this on the European Commission’s standard contractual clauses and, where the provider is certified, on the EU–US Data Privacy Framework. Please note that US authorities may, under certain circumstances, be entitled to access this data. We have no influence over such processing.

Withdrawing your consent to data processing

Many data processing operations are only possible with your explicit consent. You can withdraw consent you have already given at any time. An informal notification by e-mail is sufficient. The lawfulness of the data processing carried out before the withdrawal remains unaffected.

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

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 those 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 unless we can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or the processing serves to assert, exercise or defend 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 such marketing; this also applies to profiling to the extent that it is related to such direct marketing. If you object, your personal data will subsequently 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 infringements 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, place of work or the place of the alleged infringement. This right exists without prejudice to any other administrative or judicial remedy.

Right to data portability

You have the right to have data that we process automatically on the basis of your consent or in performance 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 take place where it is technically feasible.

Information, correction and deletion

Within the framework of the applicable statutory 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 processing, and, where applicable, a right to have this data corrected or deleted. You can contact us at any time regarding this and any other questions about personal data using the address given in the imprint.

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 applies in the following cases:

  • If you dispute the accuracy of the personal data we hold about you, we usually need time to verify this. For the duration of that check, you have the right to request the restriction of processing.
  • If the processing of your personal data was or is unlawful, you can request the restriction of 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 restriction of processing instead of deletion.
  • If you have lodged an objection under Art. 21 (1) GDPR, a balance must be struck between your interests and ours. As long as it has not been determined whose interests prevail, you have the right to request the restriction of processing.

If the processing of your personal data has been restricted, this data may – apart from being stored – only be processed with your consent, to assert, exercise or defend legal claims, to protect the rights of another natural or legal person, or for reasons of important public interest of the European Union or a member state.

SSL/TLS encryption

For security reasons and to protect the transmission of confidential content, this site uses SSL or TLS encryption. You can recognise an encrypted connection by the fact that the browser’s address bar changes from “http://” to “https://” and by the lock symbol in your browser bar. When SSL or TLS encryption is active, the data you transmit to us cannot be read by third parties.

Objection to promotional e-mails

We hereby object to the use of contact data published as part of our legally required imprint for the purpose of sending unsolicited advertising and information material. We expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, for example by spam e-mail.

4. Data collection on this website

Cookies

Cookies are small text files that are stored on your device; they do no harm. They are stored either temporarily for the duration of a session (session cookies) or permanently (persistent cookies).

This website sets exactly one cookie of its own: NEXT_LOCALE. It remembers whether you chose German or English in the language switch so that you are not sent back to the automatically detected language on every page view. It contains nothing but the language code and is not used for analysis.

This cookie is technically necessary and is stored on the basis of Art. 6 (1) (f) GDPR; under § 25 (2) no. 2 TDDDG it does not require consent, because it is strictly necessary to provide a service you have expressly requested.

All other cookies – in particular those of the analytics services described below – are only set with your consent under Art. 6 (1) (a) GDPR and § 25 (1) TDDDG.

You can set your browser to inform you when cookies are set, to allow cookies only in individual cases, to exclude them generally, or to delete them automatically when the browser is closed. Disabling cookies may limit the functionality of this website.

Server log files

The provider of these pages automatically collects and stores information in server log files, which your browser transmits automatically. These are:

  • Browser type and version
  • Operating system used
  • Referrer URL
  • Host name of the accessing device
  • Time of the server request
  • IP address

This data is not merged with other data sources. It is collected on the basis of Art. 6 (1) (f) GDPR: we have a legitimate interest in the technically error-free presentation and optimisation of our website, which requires server log files to be recorded.

Enquiries by e-mail or telephone

If you contact us by e-mail 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 this data on without your consent.

This data is processed on the basis of Art. 6 (1) (b) GDPR where your enquiry relates to the performance 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 handling enquiries addressed to us (Art. 6 (1) (f) GDPR) or on your consent (Art. 6 (1) (a) GDPR) where this has been requested.

The data you send us remains with us until you ask us to delete it, withdraw your consent to its storage, or the purpose for storing it no longer applies – for example once we have finished dealing with your request. Mandatory statutory provisions, in particular statutory retention periods, remain unaffected.

Fonts

This website uses the Geist and Instrument Serif typefaces for a consistent presentation. The fonts are delivered from our own server together with the page. No connection to third-party servers – in particular not to Google Fonts – is established, and no data about you is transmitted to a font provider.

Links to the Call’em application

This website is purely product information. There is no contact form, no registration and no newsletter here.

If you click “Start free trial” or “Sign in”, you leave this website and are taken to the Call’em application at app.callem.now. Registration for and use of the application are covered by a separate privacy policy, which is linked there.

5. Analytics

Vercel Web Analytics

This website uses Vercel Web Analytics, an analytics service provided by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA.

Vercel Web Analytics records aggregated usage statistics: which pages are opened, which referrer visitors came from, and approximate information on country, operating system and browser. The service does not set cookies and does not store or read any identifiers on your device. To distinguish visits, a pseudonymous hash value is derived from technical details of the request (including the IP address and browser identification); it does not allow any conclusions to be drawn about you personally, is not stored permanently and is not used to recognise you across other websites.

The service is used on the basis of Art. 6 (1) (f) GDPR. We have a legitimate interest in understanding how our website is used in order to improve it. Because the service neither sets cookies nor stores or accesses information on your device, consent under § 25 (1) TDDDG is not required.

Further information: https://vercel.com/docs/analytics/privacy-policy

Google Tag Manager

We use Google Tag Manager, a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.

Google Tag Manager is a tool that allows us to embed and manage tracking and analytics tools on this website. Tag Manager itself does not create user profiles, does not set cookies and does not collect personal data on its own account. It only triggers the services integrated through it, which may in turn collect personal data.

When Google Tag Manager is loaded, a connection to Google’s servers is established and your IP address is transmitted to Google; it may be transferred to the USA.

Google Tag Manager is only loaded on the basis of your consent under Art. 6 (1) (a) GDPR and § 25 (1) TDDDG. Consent can be withdrawn at any time with effect for the future.

Google Analytics

This website uses the web analytics service Google Analytics 4, provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.

Google Analytics allows us to analyse how visitors use the website. It records, among other things, which pages are opened, how long and how intensively they are viewed, how visitors reached the website, and technical details such as device type, browser, operating system and approximate location. Google Analytics uses cookies and comparable recognition technologies that can identify returning visits.

Google Analytics is only loaded and data is only collected on the basis of your consent under Art. 6 (1) (a) GDPR and § 25 (1) TDDDG. Consent can be withdrawn at any time with effect for the future.

IP anonymisation is enabled by default in Google Analytics 4: your IP address is shortened by Google within the EU or the EEA before any data is transferred to the USA. Data may nevertheless be transferred to Google in the USA; such transfers are based on the European Commission’s standard contractual clauses.

We have concluded a data processing agreement with Google. Data stored at user and event level that is linked to cookies or identifiers is deleted after 14 months at the latest.
