Master C++ ("we," "our," or "us") operates the website at www.mastercplusplus.com. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.
We do not require account creation or collect personal information such as names, email addresses, or passwords. All user data is stored locally in your browser using localStorage:
This data never leaves your browser and is not transmitted to our servers.
We use Vercel Analytics to collect anonymous, aggregated usage data such as page views and visitor counts. Vercel Analytics does not use cookies and does not collect personally identifiable information. For more details, see Vercel's Analytics Privacy Policy.
Our site may display sponsored links provided by third-party advertising networks. When you click on a sponsored link, you are directed to an external website governed by its own privacy policy. We do not control the data practices of these third parties.
To keep the site free, we may also display ads served by a third-party advertising network, which may use cookies or similar identifiers to deliver ads, limit how often you see them, and measure their performance. For visitors using a language primarily spoken in the EU/EEA, these ads only load after you accept them in our consent banner. You can change or withdraw your choice at any time via “Cookie settings” in the site footer.
If you visit one of our sponsor links, we store a timestamp in your browser's localStorage so that ads are switched off on this site for 7 days.
Master C++ does not set cookies directly; the only cookies come from the advertising network described above. We use browser localStorage and sessionStorage to store your preferences and progress. You can clear this data at any time through your browser settings.
Our site contains links to external websites (sponsor links, Buy Me a Coffee, etc.). We are not responsible for the privacy practices or content of these external sites.
Our service is educational and freely accessible. We do not knowingly collect personal information from children under 13. Since we do not collect personal data from any user, no special provisions are necessary.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the site after changes constitutes acceptance of the updated policy.
If you have any questions about this Privacy Policy, please open an issue on our GitHub repository.
