This Privacy Policy explains how QuanterLab ("we", "us", "our") collects, uses, stores, and protects your personal data when you use our platform at quanterlab.com. We are committed to protecting your privacy in accordance with the EU General Data Protection Regulation (GDPR), the German Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG), and the German Telecommunications Digital Services Data Protection Act (Telekommunikation-Digitale-Dienste-Datenschutz-Gesetz, TDDDG).
QuanterLab is currently operated as a closed beta. Paid subscriptions, billing, and payment processing are not yet active; the relevant sections will be added to this policy before any payment processing begins, and you will be notified by email.

The company replaced the founder as data controller upon its entry in the commercial register; nothing about what data is collected, stored or shared changed with that transition. See the Impressum for the full registration details.
Because of the limited scale and nature of the processing carried out, no Data Protection Officer is required under Art. 37 GDPR / §38 BDSG. All data-protection inquiries are handled directly by the controller at the email address above.

Under the GDPR, you have the right to:
You can exercise the most common rights yourself, at any time, from Settings: Download my data gives you a complete, machine-readable copy of your personal data (Access and Portability), and Delete account erases it — your account is locked immediately and all data is permanently removed within 30 days.
To exercise any other right, email us at contact@quanterlab.com. We respond within 30 days as required by Art. 12(3) GDPR. Identification is verified through the email address associated with your account.
We use only strictly necessary cookies required for the platform to function (session, cookie consent acknowledgement). We do not use advertising, tracking, or analytics cookies. For details, see our Cookie Policy.
We do not send marketing emails. All emails you receive from us are transactional — account verification, password reset, security notifications, and material changes to these legal documents. If a marketing programme is introduced in the future it will be strictly opt-in and you will be able to unsubscribe at any time.
We do not use your personal data for automated decision-making or profiling within the meaning of Art. 22 GDPR. The quantitative tools available on the platform operate on the market data and configurations you choose; they do not produce personal scores or rankings about you.
We implement appropriate technical and organizational measures to protect your data:
QuanterLab is not intended for use by individuals under the age of 18. We do not knowingly collect personal data from minors. If we become aware that we have collected data from a person under 18, we will delete it promptly.
We may update this Privacy Policy from time to time. Material changes will be communicated via email to registered users at least 30 days before they take effect. The "Last updated" date at the top of this page reflects the most recent revision.
