    2. General information

    This privacy policy explains the nature, scope and purpose of the processing of personal data on this website (hereinafter “Sudokuly”). We process as little personal data as possible (principle of data minimisation, Art. 5(1)(c) GDPR).

    Sudokuly is a daily browser puzzle game. Your game progress and your statistics are stored exclusively locally in your browser and are not transmitted to us (see section 5).

    3. Hosting

    This website is hosted by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA (hereinafter “Vercel”). The server region is set to Frankfurt am Main (EU). When the website is accessed, Vercel, as a processor, handles technical access data (see section 4).

    A data processing agreement is in place with Vercel (Art. 28 GDPR). Where data is transferred to the USA, this is based on the EU Standard Contractual Clauses (Art. 46 GDPR). The legal basis is our legitimate interest in providing the website securely and efficiently (Art. 6(1)(f) GDPR).

    4. Server log files

    When the website is accessed, the hosting provider automatically collects information that your browser transmits. This includes:

    This data is used for the technical delivery, stability and security of the website and is not merged with other data sources or used to identify individuals. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure operation). The logs are deleted after [e.g. 7 / 14 / 30] days.

    5. Local storage in your browser (localStorage)

    Sudokuly stores your game state of the day and your statistics (e.g. number of puzzles played, streaks, attempt distribution) exclusively locally in your browser using “localStorage”. This data stays on your device, is not transmitted to us or third parties, and is not accessible to us.

    This storage is strictly necessary for the function you requested (a daily game with progress) within the meaning of § 25(2) no. 2 TTDSG; no consent is required for it. You can delete this data at any time yourself by clearing the website data in your browser settings.

    6. No cookies, no tracking, no analytics

    Sudokuly sets no tracking or marketing cookies, uses no analytics services (such as Google Analytics), and embeds no third-party scripts or external font services. The fonts used are served from our own server. No profiling therefore takes place.

    7. Share function

    When you share a result via the “Share” button, the share text is provided through the functions of your own device/browser (Web Share API or clipboard). No data is transmitted to us in the process; you decide yourself whether and where you share anything.

    8. Your rights

    You have the following rights regarding your personal data vis-à-vis the controller:

    You also have the right to lodge a complaint with a data protection supervisory authority about the processing of your personal data (Art. 77 GDPR). The competent authority is that of your federal state (Bundesland) or that of the controller: [e.g. the Data Protection Commissioner of your federal state].

    9. Changes to this privacy policy

    We adapt this privacy policy whenever changes to our data processing make it necessary (e.g. when introducing user accounts or advertising). Last updated: [month year].
