These independent audits provide a critical benchmark for the company, which serves over 300 million users globally. By achieving zero nonconformities, Flo demonstrates that its internal protocols for collecting and processing sensitive health information align with the stringent requirements of GDPR. The company remains the only period tracking app to hold this dual certification, a status that requires ongoing annual oversight and full recertification every three years.

Sue Khan, VP of Privacy and Data Protection Officer at Flo Health, noted that the clean audit result reflects the maturity of their programs and a commitment to responsible data stewardship. Beyond formal certification, the company has implemented privacy-by-design principles and an independent Privacy and Security Advisory Board. Innovations such as the open-sourced Anonymous Mode, which utilizes post-quantum cryptography, highlight a broader strategy to set industry-wide benchmarks for digital health security. Flo maintains a strict policy against the sale of personal user data, reinforcing its operational model with both technical safeguards and public transparency.
