Personal Information Sources.

How We Disclose Personal Information. We share personal information with service providers who help us operate the business, including Shopify (our e-commerce platform), our payment processor, our subscription-billing app, WeTracked (server-side advertising measurement), and our email and support tools. We may also disclose information where required by law. We do not sell your personal information.

Cookies and advertising. We use cookies and tracking technologies, including a server-side conversion measurement tool (WeTracked), to operate the Site, measure performance, and report purchase events to our advertising partners (including Meta) without relying on a client-side tracking pixel in your browser. You can control cookies through your browser settings and our cookie banner where shown.

Your Rights and Choices. Under the GDPR, you have the right to access the personal information we hold about you, correct inaccurate information, request erasure, restrict or object to certain processing, receive your data in a portable format, and withdraw consent at any time where processing is based on consent. To exercise any of these rights, contact us at info@rivenflo.com.

Complaints. If you have concerns about how we handle your personal information, please contact us first. You also have the right to lodge a complaint with your local data protection authority - in Estonia, the Andmekaitse Inspektsioon (Estonian Data Protection Inspectorate).

International Transfers. Some of our service providers may process personal information outside the EU/EEA. Where this occurs, we rely on appropriate safeguards, such as the EU Standard Contractual Clauses.

Changes to This Privacy Policy. We may update this Privacy Policy from time to time. We will post the revised version here with an updated date.
