Hosting and server logs

This website is hosted by Vercel Inc. (USA). Each time the website is accessed, Vercel processes the following data:

  • IP address
  • date and time of access
  • page or file requested
  • referrer URL (the previously visited page)
  • browser, operating system and device type
  • HTTP status code and amount of data transferred

The data is processed in order to deliver the website, to keep it secure and stable, and to analyse errors. The legal basis is Art. 6(1)(f) GDPR; the legitimate interest lies in the secure and functional operation of the website. Where information on your device is accessed in the process, this is strictly necessary to provide the website (Section 25(2) No. 2 of the German Telecommunications Digital Services Data Protection Act, TDDDG).

The logs are automatically deleted after one day. Vercel processes the data as a processor on the basis of a data processing agreement (Art. 28 GDPR). For transfers to the USA, see below.

Contact form

If you send an enquiry via the contact form, the data you enter (name, email address, message) is processed in order to handle your enquiry.

The legal basis is Art. 6(1)(b) GDPR if your enquiry is aimed at a contract or at steps prior to entering into one, otherwise Art. 6(1)(f) GDPR; the legitimate interest lies in responding to enquiries.

Messages are delivered via the email service Resend, operated by Plus Five Five, Inc. (USA). Resend forwards the message to the controller’s mailbox, which is operated by an email provider. Both service providers are contractually bound as processors (Art. 28 GDPR). For transfers to the USA, see below.

The data is deleted once your enquiry has been fully dealt with, unless statutory retention obligations (e.g. under commercial or tax law) prevent this.

Your choice in the cookie banner is stored in your browser’s local storage (localStorage): consent or refusal, the time of your choice and the version of the banner. No identifier that could identify you is stored. This storage is strictly necessary so that your choice can be respected (Section 25(2) No. 2 TDDDG). After 12 months, you will be asked to choose again.

Google Tag Manager

With your consent, this website uses Google Tag Manager, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”). Google Analytics is integrated and managed via the Tag Manager. When the Tag Manager is loaded, your IP address and technical information about your browser and device are transmitted to Google.

The Tag Manager is only loaded once you click “akzeptieren” (accept) in the cookie banner. The legal basis is your consent (Section 25(1) TDDDG, Art. 6(1)(a) GDPR), which you can withdraw at any time (see above). In this context, data may be transferred to Google LLC in the USA (see below).

Google Analytics 4

With your consent, this website uses Google Analytics 4, a web analytics service provided by Google. It serves to analyse how this website is used in order to improve its content and structure. The data collected includes, among other things:

  • pages visited and time spent on them
  • interactions such as clicks, scroll depth and downloads
  • search terms entered in the Knowledge Graph Checker
  • the source of the visit (e.g. a search engine or a referring website)
  • browser, operating system, device type, screen resolution and language
  • the approximate location (country, region, city)

For this purpose, Google Analytics sets the cookies _ga and _ga_<ID>, which allow your browser to be recognised on subsequent visits. The cookies expire after 2 years. Google uses the IP address only to determine the approximate location and does not store it.

Google Signals and the data sharing settings that would allow Google to use the data for its own purposes are disabled. Google processes the data as a processor; a data processing agreement has been concluded. The analytics data is automatically deleted after 14 months.

The legal basis is your consent (Section 25(1) TDDDG, Art. 6(1)(a) GDPR). You can withdraw it at any time (see above); the Google Analytics cookies are then deleted. For transfers to the USA, see below. Further information can be found in Google’s privacy policy: https://policies.google.com/privacy

Knowledge Graph Checker

When you start a search in the Knowledge Graph Checker, your search term or the ID you entered is sent to the server of this website. The server forwards the request to the Knowledge Graph Search API of Google LLC (USA) without passing on your IP address. If you enter a person’s name, Google also receives that name. This happens regardless of your choice in the cookie banner, because the search cannot be carried out otherwise.

The legal basis is Art. 6(1)(f) GDPR; the legitimate interest lies in carrying out the search you requested. Google processes the request under its own responsibility and not as a processor. Under the terms of use of the API, Google may also use submitted content to provide, secure and improve the API. For transfers to the USA, see below.

Your search term is not stored on this website. The server logs only record that a search took place, not what was searched for.

With your consent, each search is also transmitted to Google Analytics (see above): the term exactly as entered, the type of search, the selected languages and entity types, the number of results and any error type. If you enter a person’s name, it is transmitted as well.

Transfers to the USA

Vercel Inc., Plus Five Five, Inc. (Resend) and Google LLC are based in the USA. For the USA, there is an adequacy decision of the European Commission of 10 July 2023 (EU-U.S. Data Privacy Framework, Art. 45 GDPR), under which all three companies are certified. In addition, the European Commission’s standard contractual clauses have been agreed with them (Art. 46(2)(c) GDPR).

This website contains plain links to the profiles on LinkedIn, Xing, X and GitHub. Data is only transferred when you click a link. From then on, the privacy policy of the respective platform applies.

TLS encryption

For security reasons, this website uses TLS encryption. You can recognise it by the “https://” in your browser’s address bar.

Your rights

You have the following rights:

  • access to the data stored about you (Art. 15 GDPR),
  • rectification of inaccurate data (Art. 16 GDPR),
  • erasure (Art. 17 GDPR),
  • restriction of processing (Art. 18 GDPR),
  • data portability (Art. 20 GDPR),
  • withdrawal of any consent you have given, with effect for the future (Art. 7(3) GDPR).

Please send any such requests to info@timberlin.de.

You can also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example with the authority at your place of residence or with the competent Berlin Commissioner for Data Protection and Freedom of Information.

Right to object

Where data is processed on the basis of Art. 6(1)(f) GDPR (server logs, contact enquiries unrelated to entering into a contract, search requests in the Knowledge Graph Checker), you may object to this processing at any time on grounds relating to your particular situation (Art. 21 GDPR). The data will then no longer be processed unless compelling legitimate grounds for the processing can be demonstrated which override your interests, or the processing serves the establishment, exercise or defence of legal claims.

Automated decision-making

No automated decision-making, including profiling (Art. 22 GDPR), takes place.

RenderDiff – browser extension

RenderDiff is a browser extension for Google Chrome (via the Chrome Web Store) and Mozilla Firefox (via addons.mozilla.org), provided by the operator of this website. It compares the initial HTML source code of a web page with the DOM rendered by JavaScript in order to identify SEO-relevant differences. All data processing takes place exclusively locally on the user’s device.

RenderDiff does not collect, store or transmit any personal data. No usage, telemetry or behavioural data is collected. The extension communicates exclusively with the URL of the web page that the user actively scans. No data is sent to the developer, third parties or analytics platforms. The extension does not require registration, login or authentication and does not access personal data such as names, email addresses, browsing history, passwords or form data.

RenderDiff uses the browser’s local storage API (chrome.storage.local) to store a single user setting: the preferred user agent selection (e.g. “Chrome Desktop”, “Googlebot”). This data is stored exclusively on the user’s device and is never transmitted. Scan results exist exclusively in the browser’s memory during the active session and are discarded when the tab is closed.

The extension requires the following browser permissions, each of which is used exclusively for the stated purpose: access to the active tab to determine the URL to be scanned, execution of a content script to capture the rendered DOM state, retrieval of the raw HTML source code of the scanned web page, writing scan results to the clipboard, saving report files to the downloads folder, and temporary modification of the user agent header during a scan.

The extension makes exactly one network request per scan: an HTTP GET request to the URL of the scanned web page. As a rule, this request does not contain any cookies, session tokens or authentication data; it simulates a search engine crawler request and is only made when the user actively starts a scan. In the rare case that the server responds with HTTP 401 and a Basic or Digest authentication challenge, the request is repeated once with the credentials cached by the browser, so that staging environments protected by .htaccess can also be scanned; no further requests are made. No data from the scan result is transmitted to any server.

The export functions (copy, JSON, CSV, PDF) process data exclusively locally on the user’s device. No data is transferred to external servers during export. RenderDiff is not integrated with any third-party services, APIs, advertising networks or analytics platforms.

Objection to advertising emails

The operator of this website hereby objects to the use of the contact details published in the legal notice (Impressum) for sending advertising that has not been expressly requested. The right to take legal action in the event of violations is reserved.
