We may collect the following categories of information, depending on how you interact with us:

• Contact and account information — such as name, company name, email address, phone number, and the content of messages you send through forms or email.
• Commercial and transaction-related information — where applicable, information related to commerce, orders, or platform usage you choose to share with us in a business context.
• Internet and device data — such as IP address, browser type, device identifiers, general location derived from IP, pages viewed, referring URLs, and timestamps.
• Cookies and similar technologies — see the Cookies & tracking section below.

2. How we use information

We use the information we collect to:

• Provide, operate, maintain, and improve our website and services;
• Respond to inquiries, partnership requests, and support requests;

3. How we share information

We may share information with:

• Professional advisors (such as lawyers or accountants) where reasonably necessary; and
• Authorities or third parties when required by law, legal process, or to protect the rights, property, or safety of CoreStack, our users, or others.

We do not sell your personal information for money as traditionally understood. Where required by law, we will honor opt-out rights for certain sharing that may be treated as a “sale” or “sharing” under state privacy laws.

4. Your privacy rights (United States)

Depending on where you live, you may have rights to access, correct, delete, or obtain a copy of certain personal information we hold, and to opt out of certain processing (including targeted advertising or “sales” as defined under applicable state law). You may also have the right to appeal a decision we make regarding a privacy request.

California residents (CCPA/CPRA): California consumers may have additional rights under the California Consumer Privacy Act, including the right to know, delete, correct, and opt out of certain sharing. We do not knowingly sell personal information of minors under 16. To submit a request, contact us using the information below. We will verify your request as required by law.

5. Children’s privacy (COPPA)

Our website and services are not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us and we will take appropriate steps to delete it.

6. Cookies & tracking technologies

We and our analytics partners may use cookies, pixels, local storage, and similar technologies to remember preferences, understand how our site is used, and measure the effectiveness of content. You can control cookies through your browser settings. If you disable cookies, some features may not function properly.

7. Security & retention

We implement reasonable administrative, technical, and organizational safeguards designed to protect personal information. No method of transmission over the Internet is 100% secure. We retain information for as long as needed to fulfill the purposes described in this policy, unless a longer period is required or permitted by law.

8. International users

If you access our site from outside the United States, your information may be processed in the United States or other countries where privacy laws may differ from those in your jurisdiction.
