Privacy Policy

perp101 (the “Site”) is an independent Traditional-Chinese website teaching cryptocurrency derivatives, operated by mnmedia. This policy explains what data we collect when you use the Site, how we use it, and the rights you have.

What data we collect

The Site minimises data collection and does not ask you to provide personally identifying information. The data we collect includes:

• Web analytics (anonymous, aggregated): via our self-hosted Plausible Analytics (no cookies), we record aggregate statistics such as page views, referring sites, approximate country/region, and device and browser type. This data contains no personally identifying information and does not track you across other websites.
• Performance monitoring (RUM): to keep the site fast, we record page-load performance metrics (Web Vitals such as LCP, INP, CLS), the page path (with any query string removed), and your browser’s type / user-agent string. We use this only to measure and improve performance, not to identify you.
• Error logging: when the site or your browser encounters an error, we record the error message, the URL where it occurred (query string removed), and your browser’s user-agent, so we can diagnose and fix problems.
• Issue reports: if you use the “Report an issue” feature, we store the content you submit; contact details are optional and are stored only if you choose to provide them, and used solely to reply to you.
• Site search: the keywords you search on the Site are logged (not linked to your identity) and used to improve our content and tools.

IP address and cookies

• We do not store your IP address. Your IP is used only momentarily for rate-limiting and abuse prevention; it is not retained and is not used to identify you.
• The Site uses no tracking or advertising cookies. Our web analytics is cookieless; we use browser storage only where strictly necessary to keep the site working.

How we use this data

• To improve our educational content, calculator tools, and site performance.
• To detect and fix errors and anomalies.
• To reply to questions you submit via “Report an issue”.

We do not use your data for advertising, and we do not sell or rent it to third parties.

Legal basis for processing (GDPR)

Where the GDPR applies, we rely on:

• Legitimate interests (Art. 6(1)(f)) — for our cookieless analytics, performance (RUM) and error monitoring, site-search logging, and the momentary use of your IP for rate-limiting and abuse prevention. Our interest is in operating, securing, measuring and improving the Site; this processing is limited, low-impact, and uses no personally identifying information beyond what is described above.
• Consent (Art. 6(1)(a)) — for any contact details you choose to enter in “Report an issue”. You provide these voluntarily and may withdraw consent at any time by asking us to delete them.

Service providers (sub-processors)

We keep external processors to a minimum and use no third-party advertising or analytics network (our analytics is self-hosted). The providers that process data on our behalf to run the Site are:

• Bunny.net (BunnyWay d.o.o., Slovenia / EU) — content delivery network (CDN). It processes connection data (including your IP address and request metadata) at edge servers to deliver the Site securely and quickly, under its data-processing terms.
• Hostinger — server hosting for the Site and its database.
• Proton (Proton AG, Switzerland) — our email provider, used only if you email us or provide contact details for a reply.

Our web analytics (Plausible) is self-hosted on our own infrastructure — it is not a third-party service, and your browsing data is not shared with any external analytics provider.

Third parties and affiliate links

The Site contains affiliate links to Binance. When you click through to open a Binance account or trade, you leave the Site and enter Binance’s website, at which point Binance’s own privacy policy applies and we have no control over how Binance handles your data. If you register or trade through our links we may receive compensation from Binance; however, this does not increase your costs in any way, and our referral links neither provide nor reduce any additional discount or fee. Our web analytics is self-hosted (first-party) and does not share your browsing data with any third-party analytics service.

International data transfers

Our processing is EU-based. However, our CDN (Bunny.net) runs a global edge network, so connection data may be processed on servers outside the European Economic Area (EEA) in order to serve the Site from a location near you. Where data is transferred outside the EEA, it is protected by appropriate safeguards such as the European Commission’s Standard Contractual Clauses or an adequacy decision. When you follow an affiliate link to Binance you leave the Site, and Binance becomes the controller of any data you then provide there.

Data retention and security

We keep personal data only as long as needed for the purposes above, and apply reasonable technical and organisational measures to protect it:

• Performance (RUM), error and site-search logs: retained for up to 12 months, then deleted or aggregated.
• “Report an issue” submissions (including any contact details you provide): kept until the issue is resolved and for a short period afterwards (up to 12 months), then deleted — or sooner if you ask us to.
• Aggregated, non-personal analytics: may be kept long-term to observe trends; it contains no personal data.

Your rights

You may request access to, correction of, or deletion of data you have actively provided to us (for example, contact details entered in “Report an issue”). Where the GDPR applies, you also have the rights of access, rectification, erasure, restriction of and objection to processing, and data portability. To exercise any of these rights, or for any privacy question, please contact us using the details below.

Minors

Derivatives trading carries a high degree of risk; the Site’s content is intended for adults, and we do not knowingly collect personal data from minors.

Governing law and supervisory authority

The Site is operated by mnmedia, whose data-controller establishment is in the Czech Republic (Czechia). This Privacy Policy and our processing of personal data are governed by the laws of the Czech Republic and, where applicable, the EU General Data Protection Regulation (GDPR). If you believe we have processed your personal data unlawfully, you have the right to lodge a complaint with a supervisory authority — in the Czech Republic this is the Office for Personal Data Protection (Úřad pro ochranu osobních údajů, ÚOOÚ) — and you may also contact the data-protection authority in your country of residence.

Updates to this policy

We may update this Privacy Policy from time to time. For material changes we will update the “Last updated” date at the top of this page; please review it periodically to stay informed.
