2. Hosting and Content Delivery Network
This website is hosted on Cloudflare Pages and delivered via the Cloudflare CDN. The provider is Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA.

The legal basis is Art. 6(1)(f) GDPR (legitimate interest in a secure and efficient provision of the website). Cloudflare typically stores server log files for 72 hours. Cloudflare is certified under the EU-US Data Privacy Framework. A Data Processing Addendum (DPA) pursuant to Art. 28 GDPR is in place with Cloudflare.

3. Cookies, Consent Management and Analytics Tools
Cookies
This website uses cookies and similar technologies (e.g., the browser's local storage). Cookies are small text files that are stored on your device. Technically necessary cookies are stored on the basis of Section 25(2)(2) TDDDG in conjunction with Art. 6(1)(f) GDPR. All other cookies and technologies (statistics, marketing) are only used with your consent under Section 25(1) TDDDG and Art. 6(1)(a) GDPR. You can withdraw your consent at any time with effect for the future.
Technically necessary are: storing your cookie choice (synoradzki_einwilligung, local storage, 12 months), Cloudflare security cookies (e.g., __cf_bm, 30 minutes) and the cookie kunde_sitzung (6 months) if you confirm yourself as an existing client (see section 6).
Consent via cookie banner
When you visit the website, a cookie banner is displayed through which you can give, refuse or limit your consent to individual categories. Your choice is stored in your browser's local storage so that the banner does not reappear on every page view. You can withdraw or change your consent at any time via the “Cookie settings” link in the footer. Upon withdrawal, the cookies of the affected services are deleted as far as technically possible. The legal basis is Art. 6(1)(c) GDPR (proof of consent).
Advertising check
On some German-language pages you can complete a short advertising check. Your answers are stored only in your browser's session storage (werbecheck, until the tab is closed) so that you can send them along when booking an appointment. They are not sent to Google Analytics or any other service. They are only transmitted to me if you tick the corresponding box when booking. The legal basis for storage in the browser is Section 25(2) No. 2 TDDDG (a function you requested), and for the transmission Art. 6(1)(a) GDPR.
Google Tag Manager and Google Consent Mode
This website uses Google Tag Manager. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Tag Manager is a tool used to integrate tracking and analytics tools into the website. It does not set any cookies itself and does not analyze any data. When it loads, your IP address is transmitted to Google.
Google Consent Mode is also used. It passes your choice from the cookie banner to the Google services. If you have not consented, Google Analytics and Google Ads do not set or read any cookies. Only cookieless signals are transmitted (e.g., time, page view, browser information, shortened IP address, consent status), which do not allow recognition across multiple page views. Google uses these signals for statistical modeling. The legal basis is Art. 6(1)(f) GDPR. The legitimate interest lies in measuring the effectiveness of advertising without accessing your device.
Google Analytics 4
With your consent (category “Statistics”), this website uses Google Analytics 4. The provider is Google Ireland Limited. Google Analytics makes it possible to analyze visitor behavior, e.g., page views, time spent, devices used and where visitors come from. The IP address is shortened. Cookies are set (e.g., _ga, _ga_*, storage period up to 2 years). With the same consent, the origin of the visit is stored in the browser's session storage for the own analysis of the booking page (section 6) (einstieg, until the tab is closed).
The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG. More information: Google privacy policy
Google Ads and Google conversion tracking
With your consent (category “Marketing”), this website uses Google Ads and Google conversion tracking. The provider is Google Ireland Limited. This records whether a visitor performs a certain action after clicking on a Google ad, e.g., submits an inquiry. Cookies are set (e.g., _gcl_au, storage period up to 90 days).
The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG. More information: Google privacy policy
Meta Pixel
With your consent (category “Marketing”), this website uses the Meta Pixel. The provider is Meta Platforms Ireland Limited, Merrion Road, Dublin 4, D04 X2K5, Ireland. The Meta Pixel makes it possible to track visitor behavior after they have clicked on an ad on Facebook or Instagram. This allows the effectiveness of the ads to be measured. Cookies are set (e.g., _fbp, storage period up to 90 days).
Insofar as personal data is collected with the Meta Pixel and forwarded to Meta, the operator of this website and Meta are joint controllers (Art. 26 GDPR). Joint responsibility is limited to the collection and transfer of the data. Further processing is the sole responsibility of Meta. The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG. More information: Meta privacy policy
LinkedIn Insight Tag
With your consent (category “Marketing”), this website uses the LinkedIn Insight Tag. The provider is LinkedIn Ireland Unlimited Company, Wilton Plaza, Wilton Place, Dublin 2, Ireland. The Insight Tag enables analyses of website visitors, measurement of the effectiveness of LinkedIn ads and retargeting. Cookies are set (e.g., li_sugr, bcookie, lidc, storage period up to 1 year).
The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG. More information: LinkedIn privacy policy
Attributing inquiries to ads
With your consent (category “Marketing”), click identifiers from the address of the landing page (e.g., gclid, fbclid) and campaign parameters (utm_*) are stored together with the time of the click in your browser's local storage (synoradzki_klick, 90 days; a new ad click replaces the entry, and it is deleted if you withdraw consent). If you send an inquiry via the booking page or the English contact form, this information is transmitted with it so that it can be determined which ad led to the inquiry. The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG.
If you found us through an ad and consented to marketing cookies, we later report to Meta Platforms Ireland Ltd. or Google Ireland Ltd. whether your inquiry led to a meeting or an order. Only your email address (for Meta also your phone number and name) in encrypted (hashed) form and the click identifier are transmitted, so that we can see which ads work. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time in the cookie settings.
Data transfer to third countries
When using the services mentioned, data may be transferred to the USA. Google, Meta and LinkedIn are certified under the EU-US Data Privacy Framework. An adequacy decision of the EU Commission therefore applies to the transfer (Art. 45 GDPR).
4. Google Maps
A Google Maps map is embedded in the footer of this website. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The map is only loaded when you actively click on "Load map" (two-click solution). When the map is loaded, your IP address is transmitted to Google.
The legal basis is Art. 6(1)(a) GDPR (consent). By clicking "Load map," you consent to the data transfer to Google. You can revoke your consent at any time by using the page without clicking on the map. Google is certified under the EU-US Data Privacy Framework.
More information: Google Privacy Policy
5. YouTube
Some pages of this website embed videos from YouTube. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The embedding uses the enhanced privacy mode via the domain youtube-nocookie.com.
The videos are not loaded automatically. Instead, you first see a preview image. Only when you actively click the play button (two-click solution) is a connection to YouTube/Google servers established. Your IP address is then transmitted to Google. Google may set cookies and collect usage data.
The legal basis is Art. 6(1)(a) GDPR (consent). By clicking the play button, you consent to the data transfer to Google. You can revoke your consent at any time by not playing the video or reloading the page. Google is certified under the EU-US Data Privacy Framework.
More information: Google Privacy Policy
6. Contact
If you contact me by email or phone, your information (name, email address, message) will be stored and processed to handle your inquiry. I will not share this data without your consent.
The legal basis is Art. 6(1)(b) GDPR (pre-contractual measures) or Art. 6(1)(f) GDPR (legitimate interest in processing inquiries). The data will be deleted when the purpose no longer applies or you request deletion, provided no statutory retention periods apply.
Appointment booking, calls, chat and contact form. When you book an appointment, start a call, use the chat or send a message through this website (the booking page or the contact form), I process the information you enter (name, email address, website, optionally company and phone number, email addresses of invited guests, your message and your answers to my questions) to handle your inquiry and hold the appointment. The legal basis is Art. 6(1)(b) GDPR (pre-contractual measures and performance of a contract).
Processing takes place on my own server at Hetzner Online GmbH in Germany. For appointments I use Google Calendar (Google Ireland Ltd.), which only stores the time and name. Confirmations and reminders are sent via the email service Resend. Calls take place in the browser via my own server.
Existing clients. If you confirm yourself as an existing client via the link in my email, this website stores a cookie with a random identifier for 6 months so that you do not have to enter your details again. You can sign out at any time via “Abmelden” (sign out) on the booking page, which deletes the cookie.
I store your information as long as it is needed to handle your inquiry and to meet statutory retention obligations.
My own analytics for the booking page. To improve the German booking page (“Termin buchen”), I count how visitors use them. I do not use Google Analytics or any other third-party tool for this. Only the following is recorded: which steps are opened and how long they take, which answers are chosen for my questions (for example a free consultation or a single hour, and the approximate marketing budget), at which input field someone stops or sees an error message, whether an inquiry was sent and whether it arrived, the type of device, the page of this website you came from, and where the visit came from based on the address (for example a search engine, an ad with its campaign ID, or a referring page without its query string).
My own analytics for the whole website. In the same way, I count how all pages of this website are used, so I can see which content is helpful and where I should improve something. Only the following is recorded: which page is opened, where the visit came from (the referring page without its query string, for example a search engine, ChatGPT or LinkedIn, and campaign details from the address), whether you came from another page of this website, the type of device, how far you scroll down the page, how long the page is visible, and which links and buttons you click. For a link to another website, only that website's name is stored; for email and phone links, only the fact that one was clicked, not the address or number.
Not recorded are your name, your email address, your phone number, the content of input fields and your IP address. The IP address is used only briefly in memory to block mass submissions and is not stored. No cookie is stored in your browser for this. Only if you have allowed “Statistics” in the cookie window does the browser remember how your visit started until you close the tab (see section 3). The analytics for the whole website store nothing at all in your browser. Each page view gets a random identifier that is valid only while the page is open. This means you are not recognized, not even on a later visit.
The data is stored in a database at Cloudflare (Cloudflare D1, provider see section 2). Only I have password-protected access to it. The legal basis is Art. 6(1)(f) GDPR. My legitimate interest is to understand how my website is used and where booking is difficult, and to improve both. I only look at the numbers as totals, for example per page and per week. You can object to this processing at any time; a short email to christian@synoradzki.de is enough.
7. Newsletter, Template Pack and Emails via Brevo
For my newsletter and my free template pack, I use the service Brevo for signups and for sending emails. The provider is Sendinblue SAS (Brevo), 106 boulevard Haussmann, 75008 Paris, France. The data is processed in the EU. A data processing agreement under Art. 28 GDPR is in place with Brevo.
Brevo processes your email address, the time of signup and confirmation, and your IP address. Signup uses a double opt-in: you receive an email with a confirmation link, and only then are you added to the list.
Newsletter: The signup form on this website (the “Newsletter” page and the footer of every page) is my own form. No connection to Brevo is made when the page loads. Only when you click “Subscribe” does my server send your email address to Brevo. Brevo then sends you an email with a confirmation link (double opt-in). You are only added to the newsletter list after you click that link. If you do not confirm, you will not receive the newsletter. The newsletter contains new blog articles and practical tips on SEO, Google Ads and GEO.
Template pack: The form only loads after you actively click “Load form” (two-click solution). Only then is a connection to Brevo’s servers established. After signing up, you receive the link to the template pack and, a few days later, a short follow-up email. Through that form you only receive the newsletter if you tick the separate box for it.
Brevo may measure whether emails are opened and which links are clicked.
The legal basis is Art. 6(1)(a) GDPR (consent) and Section 25(1) TDDDG. You can withdraw your consent at any time via the unsubscribe link in every email or by contacting me. Your data will be deleted as soon as you unsubscribe.
