8. REGIONAL PRIVACY DISCLOSURES

Residents of the European Economic Area and United Kingdom

Pinu is considered the "data controller" of the "personal data" (as defined under the General Data Protection Regulation, GDPR) we handle under this Policy. In other words, Pinu is responsible for deciding how to collect, use, and disclose personal data, subject to applicable law. The laws of the European Economic Area and the United Kingdom require data controllers to tell you about the legal ground that they rely on for using, sharing, or disclosing your personal data. To the extent those laws apply, our legal grounds are as follows:

  • Contractual Commitments: We may use, share, or disclose personal data to honor our contractual commitments to you. For example, we will process your personal data to comply with our agreements with you, and to honor our commitments in any contracts that we have with you.
  • With Your Consent: Where required by law, and in some other cases, we use, share, or disclose personal data on the basis of your consent.
  • Legitimate Interests: In many cases, we use, share, or disclose personal data on the ground that it furthers our legitimate business interests in ways that are not overridden by the interests or fundamental rights and freedoms of the affected individuals, such as customer service, certain promotional activities, analyzing and improving our business, providing security for the Services, preventing fraud, and managing legal issues.
  • Legal Compliance: We need to use and disclose personal data in certain ways to comply with our legal obligations.

In addition to those rights described herein, you have the right to lodge a complaint with the relevant supervisory authority. However, we encourage you to contact us first, and we will do our very best to resolve your concern. For any of GDPR concerns, you may contact us at contact@leafboatstudio.com, and specifically indicated in the subject line as "For DPO", or "For GDPR Compliance".

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be effective when the updated policy is posted within the App or otherwise made available to you.
