This Privacy Policy explains how personal data is collected, used and protected when you visit this website or use one of the mobile applications published by Mustafa Karademir (the “App”).
The following notes provide a simple overview of what happens to your personal data when you visit this website or use one of our Apps. Personal data is any data with which you can be personally identified. Detailed information can be found in the policy below.
Data processing on this website is carried out by the website operator. Their contact details can be found in the section “Information on the responsible party” below.
Some data is collected automatically by our IT systems when you visit the website. This is primarily technical data (e.g. internet browser, operating system, or time of page access). The collection of this data takes place automatically as soon as you enter this website.
As part of your use of an App, the following personal data may be collected:
The processing of this personal data is necessary to ensure the functionality of the App. The legal basis is our legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR, your consent within the meaning of Art. 6 para. 1 lit. a GDPR, or, where a contract has been concluded, the fulfilment of our contractual obligations (Art. 6 para. 1 lit. b GDPR).
You have the right at any time to receive free information about the origin, recipient, and purpose of your stored personal data. You also have the right to request the correction or deletion of this data. If you have given consent to data processing, you can revoke this consent at any time for the future. You also have the right, under certain circumstances, to request the restriction of processing. Furthermore, you have a right of appeal to the competent supervisory authority.
This website is hosted by an external service provider: Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. The personal data collected on this website is stored on the Hoster’s servers in Germany. This may primarily concern IP addresses, meta and communication data, and website accesses. No transfer to a third country takes place.
The use of the Hoster takes place in the interest of a secure, fast, and efficient provision of our online offering by a professional provider (Art. 6 para. 1 lit. f GDPR).
This site loads animation libraries (GSAP, Lenis, three.js, Vanta) from the content delivery networks cdnjs, jsDelivr and unpkg. Your IP address is transmitted to the respective provider, which is technically necessary to deliver those files (Art. 6 para. 1 lit. f GDPR). The typeface is served from our own server; no connection to Google Fonts is established.
This website sets no cookies and uses no tracking or analytics tools.
One project page embeds a trailer hosted on YouTube, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. The video is not loaded automatically. What you see initially is a still image served from our own server; no connection to Google is established at that point.
Only when you actively press play is the player loaded from
youtube-nocookie.com. From that moment YouTube receives your IP address and may
store information on your device; if you are signed in to YouTube, the playback can be
associated with your account. The legal basis for this is your consent, given by pressing
play (Art. 6 para. 1 lit. a GDPR), which you may withdraw at any time simply by not playing
the video. Further information: Google’s
privacy policy.
The operator of these pages takes 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 (e.g. when communicating by email) may have security vulnerabilities. Complete protection of data from access by third parties is not possible.
The party responsible for data processing on this website and in the Apps is:
Mustafa Karademir
Holbeinstraße 139
01309 Dresden
Germany
Email: contact.karademir@gmail.com
The responsible party is the natural or legal person who alone or jointly with others decides on the purposes and means of processing personal data.
Unless a more specific storage period has been stated within this Privacy Policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a justified request for deletion or revoke a consent, your data will be deleted unless we have other legally permissible reasons for storing it (e.g. tax or commercial law retention periods); in that case, deletion takes place once those reasons no longer apply.
Many data processing operations are only possible with your express consent. You can revoke a consent already given at any time. The lawfulness of the processing carried out until the revocation remains unaffected.
If data processing is carried out on the basis of Art. 6 para. 1 lit. e or f GDPR, you have the right at any time, for reasons arising from your particular situation, to object to the processing of your personal data; this also applies to profiling based on these provisions. If you object, we will no longer process your affected personal data unless we can demonstrate compelling legitimate grounds that override your interests, rights and freedoms, or the processing serves the assertion, exercise or defence of legal claims.
If your personal data is processed for direct marketing purposes, you have the right to object at any time; this also applies to profiling insofar as it is connected with such marketing.
In the event of violations of the GDPR, those affected have a right of appeal to a supervisory authority, in particular in the Member State of their habitual residence, their workplace, or the place of the alleged violation.
You have the right to have data that we process automatically on the basis of your consent or in fulfilment of a contract handed over to you or to a third party in a common, machine-readable format. Direct transfer to another responsible party will only be carried out insofar as it is technically feasible.
Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipient, and the purpose of data processing and, if applicable, a right to correction or deletion of this data.
You have the right to request the restriction of the processing of your personal data. This right exists in the following cases:
If you have restricted the processing of your personal data, this data, apart from being stored, may only be processed with your consent or for the assertion, exercise or defence of legal claims, or for the protection of the rights of another natural or legal person, or for reasons of an important public interest of the European Union or a Member State.
App content such as progress, settings and in-app items is stored locally on your device and, where offered, synced through the platform provider’s own service (Apple iCloud/CloudKit on iOS, Google account backup on Android). We neither access nor store this data on our own servers.
Anonymous crash logs and performance metrics may be collected through the platform’s standard diagnostics service, and only if you have opted in: on iOS under Settings → Privacy & Security → Analytics & Improvements, on Android under Settings → Google → Usage & diagnostics.
Some Apps display advertising. Where advertising networks would collect the Identifier for Advertisers (IDFA) or comparable cross-app identifiers, this only occurs after your explicit consent via Apple’s App Tracking Transparency prompt on iOS, or the corresponding consent dialog on Android. You can revoke this consent at any time: on iOS under Settings → Privacy & Security → Tracking, on Android under Settings → Google → Ads.
Apps may use Apple Game Center (leaderboards and achievements), Apple StoreKit and Google Play Services (in-app purchases and billing). These services are operated by Apple Inc. and Google Ireland Limited respectively and are governed by their own privacy policies. We receive only anonymised result data and transactional confirmations; we do not receive your Apple ID, Google account, payment details, or contact information.
We do not collect your name, email address, contacts, location, photos, or any other personally identifying information from within our Apps unless you choose to send it to us by email.
Our Apps are suitable for all ages. We do not knowingly collect personal data from children under 13. If you believe that such data may have been collected, please contact us so that it can be deleted.
