Your choice
Optional website statistics
Only with your voluntary consent does this website count page views and contact clicks in aggregate. For expert reports, we also count form views and confirmed submissions; the selected report category and contact details are not included in these statistics. It records the day, event, broad website section, language and a general source category such as Google or direct access. Specific medical page addresses, search terms, full referrer URLs, form contents and visitor identifiers are not included. These statistics are not linked to contact inquiries or book registrations.
Your choice is stored without a visitor identifier under berthold-statistics-choice-v1 in your browser’s local storage and used for up to 180 days. You can change it at any time through Statistics settings. Without consent, or when your browser sends a Do Not Track or Global Privacy Control signal, this optional measurement remains off. The legal bases are Article 6(1)(a) GDPR and, where applicable, section 25(1) TDDDG; storing your choice serves to implement it.
Aggregate counters are stored in the existing website database on ChatGPT Sites and Cloudflare infrastructure. Values older than 400 days are deleted on the next statistics event. To prevent automated abuse, a daily changing hash of the IP address and a request counter are kept until the end of the day and deleted on the next request. This protection value is not linked to statistics or contact information. Abuse prevention is based on Article 6(1)(f) GDPR.
The operator can read totals in a protected overview or through their ChatGPT account. Contact clicks are not confirmed appointments. Stored contact inquiries and waitlist registrations are shown as separate totals. The information about hosting, possible international processing and your rights also applies to these functions.
Contact
Contact form and inquiry inbox
The contact form stores your name, email address, optional telephone number, inquiry category, language, receipt time and consent version. Press inquiries may also include the outlet, topic or format and deadline. Expert-report inquiries store the selected requester group and report purpose, plus an optional organization and deadline. Please do not enter medical histories, findings or information about other patients; uploading medical records is not provided.
The purpose is to route and respond to your inquiry. Processing is based on your consent under Article 6(1)(a) GDPR. Where selecting a second-opinion or expert-report inquiry reveals a health-related interest, explicit consent also covers that processing under Article 9(2)(a) GDPR. You may alternatively contact the practice by telephone or email. Submission does not establish an appointment, treatment relationship or expert-report commission.
The information is stored in the protected website database on ChatGPT Sites and Cloudflare. The website operator can access it after signing in to a protected overview or through their ChatGPT account. No automatic email is sent. Entries older than 90 days are deleted on the next form submission or visit to the protected inbox. Separately agreed clinical or commissioned records have their own retention requirements.
You may withdraw consent for the future and request deletion by contacting info@ortho-center.eu. A daily changing IP hash and a request counter prevent abuse; expired protection values are removed on the next request. Contact form contents are not sent to usage statistics. This policy explains technical recipients, possible international processing and your other rights.
Introduction
General information
This policy concerns the personal website of PD Dr. med. Daniel P. Berthold. You can read the content without an account. Technical access data are processed during your visit. Additional data may be processed when you contact us or activate an external service such as YouTube.
Personal data such as your name, address, email address or telephone number are processed in accordance with the General Data Protection Regulation (GDPR) and applicable German data-protection law. This policy explains the nature, scope and purposes of processing and the rights of data subjects.
Technical and organizational measures are used to protect processed data. Nevertheless, internet-based transmissions can have security vulnerabilities and absolute protection cannot be guaranteed. Personal data can therefore also be communicated through alternative means, such as by telephone.
Responsibility
Data controller
The controller for this website is PD Dr. med. Daniel P. Berthold, c/o OrthoCenter München, Maximilianstraße 10, 80539 München, Germany.
Telephone via the practice: +49 89 461 34 53 0. For questions about this website and data protection, email info@ortho-center.eu.
Processing in connection with medical treatment or by linked providers is also subject to the privacy information of the responsible institution or service.
Terminology
Definitions
The following terms reflect the GDPR definitions and are intended to make this policy clear and understandable.
Personal data: any information relating to an identified or identifiable natural person. A person is identifiable directly or indirectly, particularly by a name, identification number, location data, online identifier or characteristics specific to their identity.
Data subject: any identified or identifiable natural person whose personal data are processed.
Processing: any operation involving personal data, whether or not performed by automated means. This includes collection, recording, organization, storage, adaptation, retrieval, consultation, use, disclosure, matching, restriction, erasure or destruction.
Restriction of processing: marking stored personal data with the aim of limiting their future processing.
Profiling: automated processing of personal data used to evaluate, analyze or predict particular personal aspects of an individual.
Pseudonymization: processing that prevents personal data from being attributed to a specific person without additional information held separately. That additional information must be protected by technical and organizational measures.
Controller: a natural or legal person, public authority, agency or other body that determines the purposes and means of processing, alone or jointly with others.
Processor: a natural or legal person, public authority, agency or other body that processes personal data on behalf of the controller.
Recipient: a natural or legal person, public authority, agency or other body to which personal data are disclosed. Public authorities acting within a particular statutory inquiry are not necessarily considered recipients.
Third party: a body other than the data subject, controller, processor or persons authorized to process data under the direct authority of the controller or processor.
Consent: a freely given, specific, informed and unambiguous indication of the data subject’s wishes by which they agree to the processing of their data.
Website operation
Website access, hosting and server data
This website is provided through ChatGPT Sites by OpenAI and delivered using Cloudflare infrastructure. IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany, manages the domain drdanielberthold.de and its DNS settings; IONOS does not host this website. Visiting a page involves processing technical connection and access data, particularly the IP address, requested page and access time.
These data are required to deliver content correctly, maintain the website’s functionality and security, investigate faults and defend technical systems against attacks. The legal basis is Article 6(1)(f) GDPR. The legitimate interest is the secure and reliable operation of this website.
Sites does not guarantee that data processing is restricted to Germany or the EU; this also applies to logs. Processing outside the EU or EEA is therefore possible. We do not have confirmed product-specific retention periods or anonymization assurances for provider-side access data. Questions about processing, recipients and possible international transfers can be directed to the controller identified above.
Hosting statistics
Visitor statistics provided by the host
Sites automatically records website traffic and provides the operator with statistics about unique visitors, page views and changes over time. These statistics help understand how the information on this website is used.
These provider-side statistics are separate from the website-code functions. Our optional aggregate website statistics are described separately below; we do not embed advertising trackers; this does not mean the hosting provider processes no usage data or never uses cookies. Our website code does not transmit answers from the local interactive checks. The Sites documentation provides further information about visitor statistics.
Communication
Connection encryption and contacting us
When you access a page via https://, the connection between your browser and the web server is encrypted with TLS. Your browser’s security information shows the connection status. Website encryption does not mean that a separately sent email is end-to-end encrypted.
If you contact us by email or telephone, the information voluntarily provided is stored to process and respond to your inquiry. Depending on its purpose, the legal basis is Article 6(1)(b) or 6(1)(f) GDPR. If health data are involved, the requirements of Article 9 GDPR also apply.
Please do not send complete medical records or imaging datasets in an initial unencrypted email. A suitable transfer method for sensitive documents is agreed after initial contact.
The book waiting list accepts registrations with an email address. This website does not provide patient accounts or medical-record uploads. Answers in the local interactive checks and orientation tools are evaluated only in your browser’s memory, are not sent to the practice and are not stored permanently. Reloading the page resets those answers.
Book updates
The Run Code waiting list
When you register, we store your email address, the time and version of your consent, and your choice about optional running updates. These details are used to inform you about the official presale and publication of The Run Code. You receive running updates only if you select that additional option. The legal basis is your consent under Article 6(1)(a) GDPR.
Registrations are stored in this website’s database. The website operator has access to a protected overview and can receive information about new registrations in their ChatGPT account. This involves processing the email address, registration time and selected updates. ChatGPT Sites and ChatGPT are used for hosting and operator notifications. The form does not request health data. Registering does not create a treatment relationship or constitute a book purchase.
You may withdraw your consent at any time with effect for the future and request deletion of your registration by emailing info@ortho-center.eu. We retain your details until you withdraw consent or the relevant information purpose no longer applies. The other sections of this policy describe technical providers and your further rights.
To protect against abusive registrations, the waiting-list function stores a daily changing hash of the IP address with a request counter. Expired counters are deleted on the next request after the day ends. The waiting-list function does not store the full IP address.
Retention
Erasure, restriction and retention periods
Personal data are processed and stored only for as long as necessary for the relevant purpose or as required by statutory retention periods. When the purpose no longer applies or a mandatory period ends, data are erased or processing is restricted in accordance with the law.
Recipients may include technical service providers used for hosting, security and communication. Data are disclosed to other parties only when required to handle an inquiry, to comply with a legal obligation or on the basis of consent.
Your rights
Rights of data subjects
You can exercise your rights at any time using the contact details above. Each right applies subject to the relevant legal conditions.
Confirmation and access: you may request confirmation of whether personal data are being processed. If they are, you may request access and a copy free of charge. The information includes, in particular, purposes, data categories, recipients, retention periods, the source of the data, your other rights, automated decisions and, where relevant, transfers to third countries.
Rectification: you may request prompt correction of inaccurate personal data and completion of incomplete personal data.
Erasure: you may request erasure, particularly where data are no longer necessary, consent has been validly withdrawn, a valid objection applies, processing was unlawful or a legal obligation requires erasure. Statutory retention obligations and other legal exceptions remain unaffected.
Restriction of processing: you may request restriction if you contest the accuracy of data, processing is unlawful and you prefer restriction to erasure, the data are needed for legal claims, or a decision on an objection is pending.
Data portability: where automated processing is based on consent or a contract, you may receive the data you provided in a structured, commonly used and machine-readable format and, where technically feasible, have them transferred directly to another controller.
Objection: for reasons relating to your particular situation, you may object to processing based on Article 6(1)(e) or 6(1)(f) GDPR. Following such an objection, processing stops unless compelling legitimate grounds or legal claims justify its continuation. You may object to direct marketing at any time without giving a specific reason; your data must then no longer be processed for direct marketing.
Automated decisions, including profiling: you have the right not to be subject to a decision based solely on automated processing that produces legal effects or similarly significantly affects you, unless a statutory exception applies. This website does not carry out such automated decision-making or profiling.
Withdrawal of consent: you may withdraw data-protection consent at any time with effect for the future. This does not affect the lawfulness of processing carried out before withdrawal.
Right to complain: you may complain to a data-protection supervisory authority, particularly in the member state of your habitual residence, workplace or the suspected infringement. The Bavarian State Office for Data Protection Supervision is one possible contact for non-public bodies in Bavaria.
Legal bases
Legal bases and legitimate interests
Article 6(1)(a) GDPR applies when consent is obtained for a specific purpose. Processing necessary to perform a contract or take steps before entering a contract is based on Article 6(1)(b) GDPR.
Article 6(1)(c) GDPR applies where processing is required by a legal obligation. In rare cases, Article 6(1)(d) GDPR may apply to protect a person’s vital interests.
Article 6(1)(f) GDPR applies where processing is necessary for a legitimate interest and the interests, fundamental rights and freedoms of data subjects do not override it. Legitimate interests include, in particular, the secure operation of this website, handling inquiries and conducting business activities.
Special categories of personal data, particularly health data, are additionally subject to Article 9 GDPR and the applicable professional and health-law provisions.
Required information
Providing personal data
Providing personal data may be legally required, contractually agreed or necessary to enter a contract. If required information is not provided, an inquiry may be impossible to process or a contract may not be concluded.
You may contact the practice before sending information. The practice can explain in the individual case which details are required, the basis on which they are processed and the possible consequences of not providing them.
Technical services
Cookies, fonts, analytics and advertising
Our aggregate website statistics activate only after consent. Advertising or social-media trackers and marketing cookies are not included. Google Analytics, Google Ads or AdWords, and comparable conversion-tracking services are not currently used.
Necessary storage or security mechanisms may be used for technically essential hosting functions. Browsers can be configured to block cookies or ask before saving them; this may impair technically necessary functions.
The website does not load Google Fonts or other webfonts from external font servers. Fonts are local or system fonts already available on the device.
If optional analytics, marketing or external font services are added in future, this policy and, where required, consent controls will be updated before those services are used.
Third-party services
External links and services
Doctolib booking, Google Maps, Jameda, PubMed, ORCID, specialist journals, media articles and, where applicable, social networks are opened only as external links. A connection to the provider is established only when you click the link. The respective service’s privacy information then applies.
Videos initially display only a locally stored preview image. The YouTube player is loaded through youtube-nocookie.com’s privacy-enhanced mode only after you select Play video. This establishes a connection to YouTube or Google. In particular, your IP address, device and usage information, and the page accessed may be processed. If you are signed in to YouTube, the visit may be associated with your account. Google’s privacy policy provides further information.
The website does not automatically embed Google Maps, Jameda widgets, Facebook or Instagram feeds, or plugins from X, XING or LinkedIn. Simply viewing a page with a YouTube preview image does not establish a connection to YouTube.
If the type or scope of external integrations changes, this information will be updated before activation.
