Privacy Policy

Market Memory Kft. acts as the data controller for personal information collected through our platform. This privacy policy explains how we collect, use, protect, and handle your personal data in compliance with the General Data Protection Regulation (GDPR) and Hungarian data protection laws.

When you register, we collect your email address, chosen username, and password (encrypted). We also collect information about how you use our platform, including pages viewed, features accessed, and time spent on the service. For security and functionality purposes, we collect IP addresses, browser type, device information, and use cookies. We maintain records of your communications with our support team when you contact us for assistance.

We process your personal data based on contract performance for providing our services, legitimate interest for platform security, analytics, and service improvement, consent for marketing communications where applicable, and legal obligation for data retention requirements.

We use your data to provide and maintain our research platform, handle user authentication and account management, ensure platform security and prevent fraud, improve our service through analytics, provide customer support and communication, and comply with legal obligations.

Account data is retained while your account is active and for three years after account closure. Usage logs are retained for twelve months for security and analytics purposes. Support communications are retained for two years to help us provide better assistance and resolve any ongoing issues.

Under GDPR, you have the right to access your personal data and receive a copy, rectify inaccurate or incomplete data, erase your data under certain circumstances, restrict processing in specific situations, receive your data in a structured format for portability, object to processing based on legitimate interest, and withdraw consent at any time where consent is the legal basis for processing. To exercise these rights, contact us through our official channels.

We implement appropriate technical and organizational measures to protect your personal data, including encryption of data in transit and at rest, access controls and authentication systems, regular security assessments, and staff training on data protection practices.

We do not sell your personal data. We may share data with service providers who assist in platform operation under strict data processing agreements, legal authorities when required by law or to protect our legal rights, and business successors in case of merger or acquisition with user notification.

We use strictly necessary cookies for platform functionality and optional analytics/measurement cookies only after user consent. You can manage these choices via the on-site Privacy Settings control at any time and withdraw consent without affecting core account access.

Where affiliate links are shown (for example, Amazon Associates links), optional measurement may be used to understand aggregate click performance and content usefulness. We do not sell personal data and do not use optional cookies unless the relevant preference has been enabled.

If we transfer data outside the EU, we ensure adequate protection through European Commission adequacy decisions, standard contractual clauses, or other appropriate safeguards as required by GDPR.

Our service is not intended for individuals under 16 years of age. We do not knowingly collect personal data from children under 16 without parental consent. If we become aware that we have collected personal information from a child under 16, we will take steps to delete such information.

We may update this privacy policy periodically to reflect changes in our practices or legal requirements. We will notify users of material changes through our platform or by email. Your continued use of our service after any modifications constitutes acceptance of the updated policy.

In case of a personal data breach that poses a risk to your rights and freedoms, we will notify you within 72 hours of becoming aware of the breach.

For privacy-related questions or to exercise your rights, contact us through the official Market Memory channels on our Contact page. For urgent privacy matters, use the contact methods specified on our website. If required by law, we will designate a Data Protection Officer and provide contact information.

You have the right to lodge a complaint with the Hungarian National Authority for Data Protection and Freedom of Information (NAIH) if you believe your data protection rights have been violated.
