Quartermark

Privacy Policy

Last updated: July 2026

This Privacy Policy explains how Quartermark ("Quartermark," "we," "us," or "our") collects, uses, discloses, and protects information when you visit quartermark.com or use our website and sign-in features (the "Site"). It applies to visitors and account holders on the marketing site and login. If the platform's fund-reporting product becomes available to you, handling of portfolio company documents and financial data will follow these same principles and, where applicable, a separate data processing agreement with your fund.

Quartermark is not yet an incorporated legal entity. Once incorporated, this policy will be updated to name the incorporated entity as the data controller.

1. Information We Collect

Account information. When you sign in using Google, we receive your name, email address, and profile picture from Google, as permitted by your Google account settings. We do not receive your Google password.

Session data. To keep you signed in, we set a secure, encrypted session cookie. This cookie is necessary for the sign-in feature to function and does not track you across other websites.

Local preferences. Your light/dark theme preference is stored in your browser's local storage. This information stays on your device and is not transmitted to our servers.

Communications. If you email us — for example, to request a demo — we receive whatever information you choose to include in that message.

We do not currently operate a self-serve checkout, so we do not collect payment card information through the Site. If we introduce billing in the future, payment information will be collected and processed by a third-party payment processor, and this policy will be updated accordingly.

2. How We Use Information

We use the information above to authenticate you and maintain your signed-in session, respond to inquiries and demo requests, maintain the security and integrity of the Site, and comply with legal obligations.

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

We do not use customer information — including any documents or financial data submitted through the product once it is live — to train artificial intelligence or machine learning models. This applies to all data collected through the Site and, in the future, the product.

3. Legal Basis for Processing (EEA/UK Users)

Where the General Data Protection Regulation ("GDPR") applies, we process your information on the following legal bases: performance of a contract, where processing is necessary to provide the sign-in feature you requested; legitimate interests, where processing is necessary to secure and operate the Site, provided those interests are not outweighed by your rights; and consent, where you have given it — for example, by voluntarily emailing us.

4. Sharing of Information

We share information only with service providers acting on our behalf: Google, to provide the "Sign in with Google" authentication feature, and Vercel Inc., our hosting and infrastructure provider, which stores and serves the Site's data.

These providers may process data outside your country of residence, including in the United States. Where required, we rely on appropriate safeguards, such as Standard Contractual Clauses, to lawfully transfer data internationally.

We do not otherwise share, sell, or disclose your personal information to third parties, except with your consent; to comply with a legal obligation, court order, or governmental request; to protect the rights, property, or safety of Quartermark, our users, or the public; or in connection with a merger, acquisition, or sale of assets, in which case we will notify you before your information becomes subject to a different privacy policy.

5. Data Retention

We retain account information for as long as your account remains active. If you ask us to delete your account and associated data, we will do so within a reasonable time, except where we are required to retain certain information to comply with a legal obligation.

6. Your Rights

Depending on your location, you may have the right to access the personal information we hold about you, correct inaccurate information, request deletion of your information, request a copy of your information in a portable format, object to or restrict certain processing, and withdraw consent where processing is based on consent.

To exercise any of these rights, email us at hello@quartermark.com. We will respond within a reasonable time and in accordance with applicable law.

If you are located in the European Economic Area, you also have the right to lodge a complaint with your local data protection supervisory authority. As these Terms are governed by the law of Cyprus, the relevant authority is the Cyprus Office of the Commissioner for Personal Data Protection.

7. Security

We apply industry-standard technical and organizational measures to protect information, including encryption in transit (TLS 1.2+) for all Site traffic. Further detail on our security practices, including those that apply to the product's handling of fund and portfolio company data, is available on our Security page. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

8. Children's Privacy

The Site is intended for business use by adults and is not directed at children. We do not knowingly collect personal information from anyone under 18. If you believe a child has provided us with personal information, contact us and we will delete it.

9. Cookies

We use only the cookies strictly necessary to operate the sign-in feature (a session cookie). We do not use advertising or cross-site tracking cookies. If we introduce analytics or additional cookies in the future, we will update this policy and, where required by law, request your consent first.

10. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last updated" date above and, where appropriate, notify account holders directly.
