STACK Privacy Policy

Last Updated: October 26, 2025

1. Introduction

STACK is committed to protecting your privacy and ensuring the security of your personal data. This Privacy Policy explains how we collect, use, store, and share your personal information when you join or interact with our community. STACK facilitates the exchange of knowledge, tools, and strategies among investors in a curated environment. We host an active Discord server with dedicated channels for market analysis, trade discussions, personal finance frameworks, and more. We organize discussions, Q&As, and resource-sharing to help members learn and improve. Our focus is on sharing frameworks—such as evaluating tech stock fundamentals or structuring investment theses—rather than stock tips or generic advice. We also compile and publish insights from the community's best ideas and discussions.

STACK is operated by a company registered in the Netherlands, and all data processing occurs within the Netherlands. By joining STACK or providing your personal data, you agree to the practices described in this policy. If you have any questions, please contact us at help@stacknetwork.io.

This policy complies with the General Data Protection Regulation (GDPR) of the European Union, as STACK is based in the EU. We process personal data lawfully, fairly, and transparently, based on legitimate interests (such as managing community membership and providing tailored experiences) or your consent where required.

2. Personal Data We Collect

We collect the following personal data to manage your membership and enhance your experience in the STACK community:

• First name
• Last name
• Email address
• LinkedIn page
• Company and job title
• Country of residence
• Discord handle
• Investment experience
• Investment interests

We collect this data directly from you when you apply for membership, update your profile, or interact with our community features.

3. Purposes of Data Collection and Processing

We collect and process your personal data for the following purposes:

• To manage your membership in the STACK community, including verifying eligibility and granting access to our Discord server and resources.
• To provide a tailored experience, such as recommending discussions, events, or resources based on your investment experience and interests.
• To communicate with you about community events, activities, updates, and insights compiled from community discussions.

Our lawful basis for processing under GDPR is primarily our legitimate interests in operating and improving the community, as well as your consent (e.g., when you provide data during signup). 

4. Data Storage and Retention

Your personal data is stored securely in the Netherlands. Access is strictly restricted to authorized STACK team members who need it to perform their duties, such as community management or event coordination.

We retain your data for as long as your membership is active. After your last activity (e.g., last login or interaction), we store your data for a maximum of 24 months to comply with legal obligations or resolve disputes. After this period, your data is securely deleted or anonymized.

5. Sharing of Personal Data

We do not sell or rent your personal data to third parties.

We may share aggregated, anonymized data (e.g., community-wide investment trends) with partners for analytical or collaborative purposes. Any such sharing is done in compliance with data protection regulations, including GDPR, and ensures that no individual can be identified from the aggregated data.

6. Your Rights Under GDPR

As a data subject under GDPR, you have the following rights regarding your personal data:

• Right to Access: Request a copy of the personal data we hold about you.
• Right to Rectification: Correct inaccurate or incomplete data.
• Right to Erasure ("Right to be Forgotten"): Request deletion of your data where there is no compelling reason for us to retain it.
• Right to Restriction of Processing: Limit how we use your data in certain circumstances.
• Right to Data Portability: Receive your data in a structured, machine-readable format and transfer it to another controller.
• Right to Object: Object to processing based on legitimate interests, including for direct marketing (though we do not engage in marketing beyond community communications).
• Right to Withdraw Consent: If processing is based on consent, withdraw it at any time without affecting prior processing.
• Right to Lodge a Complaint: File a complaint with a supervisory authority, such as the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. The "Last Updated" date at the top indicates the most recent revision.
