NoteGraph ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and disclose information when you use our Biological Rhythm & Sleep Planner.

2. IAB TCF v2.3 Disclosure

We participate in the IAB Europe Transparency & Consent Framework (TCF v2.3) and comply with its Specifications and Policies. NoteGraph uses a certified Consent Management Platform (CMP) to ensure technical signals are sent to advertising partners, including Google (Vendor ID 755).

As of March 1, 2026, we utilize the "Disclosed Vendors" segment in our TC strings to provide verifiable proof of vendor disclosure to our users in the EEA, UK, and Switzerland.
