Privacy Policy

Effective Date: June 4, 2026 Last Updated: July 30, 2026

This Privacy Policy describes how Paul Sukhanov (“we,” “us,” or “our”) collects, uses, and protects your information when you use Cronologies (the “Service”). By creating an account or using the Service, you agree to the practices described here.

1. Information We Collect

Information you provide directly

  • Email address. We collect your email address when you register so we can verify your account and communicate with you.
  • Account verification data. When you confirm your email, we record that the verification occurred (and the time it occurred).
  • Data you upload. The Service lets you upload datasets and files for visualization. We store and process this content on your behalf to provide the Service.

Information collected automatically

  • Technical data. IP address, browser type, device information, and similar identifiers.
  • Usage data. Pages visited, features used, timestamps, and interactions with the Service.
  • Cookies and similar technologies. See Section 7.

2. How We Use Your Information

We use the information we collect to:

  • Create and manage your account and verify your email address.
  • Provide, operate, and maintain the data visualization features of the Service.
  • Process and display the data you upload.
  • Send service-related communications (e.g., verification, security alerts, important updates).
  • Send marketing communications, where permitted and subject to your ability to opt out.
  • Monitor, secure, and improve the Service, and detect or prevent fraud and abuse.
  • Comply with legal obligations.

Where data protection laws such as the GDPR apply, we rely on the following legal bases: performance of a contract (to provide the Service you sign up for), your consent (e.g., for marketing), our legitimate interests (e.g., securing and improving the Service), and compliance with legal obligations.

4. How We Share Your Information

We do not sell your personal information. We may share information with:

  • Service providers / processors who help us operate the Service, such as hosting, serverless infrastructure, email verification, storage, security, and similar operational services. These providers are authorized to process information only as needed to provide their services to us.
  • Legal and safety reasons, where required by law or to protect our rights, users, or the public.
  • Business transfers, in connection with a merger, acquisition, or sale of assets.

5. Data You Upload

You retain ownership of the datasets and files you upload. We access and process this content only to provide the Service to you, as described in our Terms of Service. We do not use your uploaded data to train models or for unrelated purposes unless you give explicit consent.

6. Data Retention

We keep your personal information for as long as your account is active or as needed to provide the Service. You may request deletion of your account and associated data at any time (see Section 8). We may retain certain information where required by law or for legitimate business purposes such as fraud prevention.

7. Cookies and Tracking

We use browser storage and similar technologies to keep you logged in, remember preferences, store local edits, and understand how the Service is used. You can control cookies and site storage through your browser settings. We do not currently use advertising cookies.

8. 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.
  • Object to or restrict certain processing.
  • Receive a copy of your data in a portable format.
  • Opt out of marketing communications.

California residents (CCPA/CPRA): You have the right to know what personal information we collect, to request deletion, to correct it, and to opt out of any “sale” or “sharing” of personal information. We do not sell personal information. We will not discriminate against you for exercising these rights.

To exercise any of these rights, contact us at privacy@treeofknowledge.app. We may need to verify your identity before responding.

9. Data Security

We use reasonable technical and organizational measures to protect your information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

10. International Data Transfers

If you access the Service from outside the United States, your information may be transferred to and processed in the United States or other locations where we or our providers operate. Where required, we use appropriate safeguards for international data transfers.

11. Children’s Privacy

The Service is not directed to children under 13 (or the minimum age in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version with a new “Last Updated” date and, where appropriate, notify you.
