I am the controller for the processing described in this notice. Contact me about privacy or your rights at contact@michaelkremmel.de.

This notice covers the portfolio at michaelkremmel.de and www.michaelkremmel.de, the technical demos at demo.michaelkremmel.de, and related email and postal correspondence. The demo-specific browser storage is explained separately below. Linked stores and services also provide their own privacy information.

The website, demo webspace and email mailboxes are hosted by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. IONOS receives the connection data needed to deliver a requested page or file, including your IP address.

IONOS’s Webhosting documentation describes logs containing the requested page or file, referrer, browser type and version, operating system, device type, access time and an anonymized IP address. It states that visitor data is anonymized at collection and stored for eight weeks.

Processing necessary to deliver the website and maintain its security and stability is based on Article 6(1)(f) GDPR. My legitimate interests are operating a reliable website and detecting errors and misuse. See IONOS’s Webhosting processing information for the provider’s description.

IONOS Webhosting provides WebAnalytics visitor statistics. IONOS describes collection through logfiles or a pixel, without cookies, with IP addresses anonymized directly after transmission. The statistics concern page requests, referrers, browser, operating system, device type, access time and approximate access location.

The purpose is statistical evaluation and technical improvement of the website. Processing of request data for these purposes is based on Article 6(1)(f) GDPR and my interest in understanding and improving how the site is used. Source hosting logs follow the retention described above; genuinely anonymous aggregate results do not identify individual visitors.

The portfolio does not include a separate Google Analytics installation or an additional advertising pixel. For IONOS’s own service, see its WebAnalytics processing information. YouTube processing after video activation is described below.

You can email contact@michaelkremmel.de for general inquiries or support@michaelkremmel.de for asset support. I process your email address, any name you supply, message contents, technical mail information and attachments to respond and handle your request. The mailboxes are hosted by IONOS.

For contractual support or steps you request before entering a contract, the legal basis is Article 6(1)(b) GDPR. For other inquiries, it is Article 6(1)(f) GDPR and my interest in communicating with people who contact me. Handling requests required by law, including data-protection requests, may instead be based on Article 6(1)(c) GDPR.

Routine inquiry and support messages, including attachments, are subject to automatic mailbox deletion on a three-month cycle. This cycle applies to routine mailbox contents; statutory business records and provider backups follow their own retention rules. Legal retention obligations and the establishment, exercise or defence of legal claims can require particular records to be retained longer.

Please send only the information needed to investigate an issue. If you send a sample project, remove credentials and unrelated personal or third-party data first. I do not export customer information from Unity for a separate customer database.

Postal correspondence

The postal address uses the authorized mail-receiving and scanning service of Akteno GmbH, Welserstraße 3, 87463 Dietmannsried, Germany. When you write to me there, Akteno receives and scans the correspondence so that I can read it digitally. This involves sender and recipient details, the contents of the letter and associated documents.

The legal basis depends on the correspondence: Article 6(1)(b) GDPR for contractual matters, Article 6(1)(c) for legal obligations, or Article 6(1)(f) and my interest in receiving and managing other correspondence. The three-month mailbox rule above does not apply to postal originals or Akteno’s document archive. Postal records are kept according to their purpose, applicable retention duties and the service’s storage arrangements; Akteno’s published terms provide for storage of originals during the contract and return at its end unless destruction is requested.

Further information: Akteno privacy information and service terms.

The portfolio’s fonts, styles, scripts, images and video preview pictures are served from my own website. Visiting a page does not load fonts from Google Fonts or another external font service.

The portfolio’s own scripts do not set cookies or create visitor profiles. When you use the theme toggle, your selected light or dark appearance is saved in your browser’s localStorage under mk-theme, together with an expiry time, for up to 30 days. The preference is read on later visits and expired or invalid entries are removed on the next visit. It contains no visitor identifier and is not sent by the portfolio to a server. You can change it using the toggle or remove it by clearing this website’s browser data. This functional storage provides the appearance you explicitly request and falls under Section 25(2)(2) TDDDG; no analytics or advertising purpose is involved.

Slideshow, image-viewer and YouTube-choice state stays in the current page. Your browser can cache website files as part of ordinary page delivery. Loading a YouTube player or opening a technical demo involves the additional processing described in the next sections.

Videos are provided by YouTube, a Google service. For users in the EEA, the service provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. A product page initially shows a local preview. Selecting its play icon opens a privacy choice. A YouTube player connects only after you choose “Allow and play”. Once allowed, other videos on that page connect only when you select them.

Activation connects your browser to YouTube and other Google services. Google receives your IP address, device and browser information, the website’s origin and information about use of the player. The standard player can use cookies or similar browser storage for playback, analytics and personalized advertising. Google may combine information with your Google account or other data according to your settings and its policies.

Loading the player is optional. The legal basis for activating this third-party content and the associated consent-based processing is Article 6(1)(a) GDPR; consent to storage or access on your device is governed by Section 25(1) TDDDG where required. Declining does not prevent you from reading the rest of the site. An ordinary link to watch on YouTube is also available.

Your choice applies to YouTube videos on the current page and is held only in memory. No preference is saved in cookies or browser storage. Allowing videos does not load them all; only the video you select is connected, and that selection requests playback. You can open “Video privacy” in the footer and choose “Turn off videos” to remove active players and withdraw permission on this page. This does not undo earlier lawful processing, delete data already sent to Google, or erase cookies it has already stored. You can clear those using your browser and manage Google activity through your Google account.

Google controls retention of the data it receives. Its periods depend on the data, purpose and your account settings. Read Google’s Privacy Policy, retention information and cookie information. International transfers are explained below.

The separately opened demos at demo.michaelkremmel.de run Unity applications in your browser. Their hosting receives connection data when you request the demo and its application files. The purpose is to provide the interactive demonstration you choose to open; processing required for delivery and operation is based on Article 6(1)(f) GDPR and my interest in demonstrating my work.

Unity demo loaders include IndexedDB caching (UnityCache) and browser-backed filesystem support (IDBFS). The Volumetric Lighting scenes also register service workers that cache application files for subsequent use. These files and stored application data can remain after you close the page; they are separate from the portfolio’s own scripts and from support email.

There is no common three-month lifetime for this browser storage. Retention depends on the particular demo, your browser’s storage management and when site data is cleared. You can remove data for demo.michaelkremmel.de through your browser’s site-data controls, including its caches, IndexedDB data and service workers. Restricting storage can affect caching or persistence features.

Unity explains its WebGL cache behavior in its technical documentation. The general hosting information above also applies to requests for demo files.

Store buttons lead to external services, including the Unity Asset Store and, where linked, Fab. The destination receives connection data when you visit it and handles checkout, payment and any account information under its own terms and privacy notice. This portfolio has no checkout or user account system.

Unity Asset Store affiliate links contain aid=1101l44FL, an identifier for my affiliate account. A qualifying purchase may earn me a commission. A static pubref label identifies which button or project a link belongs to; it does not identify an individual visitor. These labels are part of the destination URL; the portfolio does not load a Unity or Partnerize tracking script or pixel merely because you view a page.

Unity’s affiliate program uses Partnerize for attribution and reporting. After following an affiliate link, the destination and its providers may process click, device, cookie and transaction information to attribute a purchase. Their own notices and consent choices apply.

Provider information: Unity Privacy Policy, Unity affiliate program, Partnerize Privacy Policy and Epic Games Privacy Policy for Fab.

Recipients are the service providers described in the relevant sections: IONOS for hosting and email, Akteno for postal handling, and Google when you activate YouTube. External store and affiliate providers receive data when you follow their links. Data may also be disclosed to authorities, courts or professional advisers when necessary to meet a legal obligation or deal with legal claims.

Google operates internationally, including in the United States. Google LLC is certified under the EU–US Data Privacy Framework. Transfers covered by the applicable adequacy decision can rely on Article 45 GDPR. Google states that it uses standard contractual clauses where required for transfers not covered by an adequacy decision.

You can consult Google’s transfer safeguards and its Data Privacy Framework entry for the scope of certification and further information on obtaining the relevant safeguards.

The category-specific periods and criteria are set out above. Personal data is retained only for its stated purpose or where a legal obligation or legitimate legal-claim requirement justifies longer storage. German retention rules can require relevant business correspondence to be kept for six years, accounting documents for eight years and books or certain tax records for ten years, depending on the document and applicable law.

Provider backups, postal originals, anonymous hosting statistics, browser caches and data independently held by Google or a store are not governed by the support mailbox’s three-month deletion cycle. Their relevant purposes, statutory duties, provider retention rules or browser controls determine retention.

Subject to the conditions in the GDPR, you have the right to access your personal data, correct inaccurate data, request erasure, restrict processing, and receive or transfer data where the right to data portability applies (Articles 15–20 GDPR).

You may withdraw consent at any time with effect for the future. Withdrawal does not affect the lawfulness of processing before withdrawal. For YouTube, open “Video privacy” in the footer and choose “Turn off videos”, or contact me about other consent-based processing.

Where processing is based on Article 6(1)(f) GDPR, you have the right to object at any time on grounds relating to your particular situation. I must then stop unless compelling legitimate grounds override your interests, rights and freedoms, or processing is needed for legal claims. You may object to any processing for direct marketing at any time without giving reasons.

To exercise your rights, email contact@michaelkremmel.de. I may need proportionate information to verify your identity before disclosing or changing personal data.

You have the right to lodge a complaint with a data-protection supervisory authority under Article 77 GDPR, in particular in the EU member state of your habitual residence, place of work or the alleged infringement. You do not have to contact me first.

The German supervisory-authority directory helps you find the relevant state authority. Your right to complain is not restricted to the state containing my postal address.

You are not required to contact me, load a YouTube video, open a demo or follow a store link. Connection data is needed to deliver the website you request. If you contact me without a usable reply address or enough information about the issue, I may be unable to answer or provide the requested support.

There are no newsletter subscriptions or visitor accounts on this portfolio. I do not use automated decision-making that produces legal or similarly significant effects under Article 22 GDPR. Google’s processing after you activate a player is described in its own privacy information.
