Did Glow have a data breach?

Glow has had two separate security incidents. In 2016, Consumer Reports found that Glow's Partner Connect feature could share a user's health data with anyone who sent a link request, without the user's confirmation. Glow stated it patched the issue. The California Attorney General settled with Glow in September 2020 for $250,000 over this vulnerability. Separately, in October 2024, a security researcher found an API bug that exposed personal data of about 25 million Glow users, including names, location data, and uploaded images.

Does Glow sell your data?

Check Glow's privacy policy directly for current data sharing practices. The core issue is architectural: Glow stores your data on its servers. That means the data can be shared, subpoenaed, or exposed regardless of current policy commitments.

Can my partner see my Glow data?

Yes. Glow offers partner sharing features. This is a real advantage for couples tracking fertility together, but it requires both partners to have accounts on Glow's cloud infrastructure.

Floriva vs Glow: On-Device Privacy vs Cloud Fertility Tracking

Floriva vs Glow compared on privacy, data storage, and features. Glow is cloud-based, settled with the California AG in 2020 for $250K over a data vulnerability, and had a separate API bug in 2024 that exposed data of about 25 million users. Floriva stores everything on your device.

Glow is built for people actively trying to conceive. It has partner sharing, community forums, and detailed fertility metrics. It is also a cloud based app that stores your health data on company servers. Those servers have had two documented security incidents: a 2016 vulnerability found by Consumer Reports that led to a $250,000 California AG settlement in 2020, and a separate 2024 API bug that exposed data of about 25 million users. Floriva is built for people who want their cycle data to stay on their device. No servers, no accounts, no data to subpoena. Less fertility specific depth, more privacy by design. The Core Difference Glow is a cloud app. Your cycle data, fertility markers, symptoms, and partner shared information live on Glow's servers. You need an account. The company has access to your data. Floriva is an on device app. Your data lives on your phone. No account. No server copy. The company cannot access your data because the company does not have it. This is not a policy difference. It is an architecture difference. Glow could change its privacy policy tomorrow and your data would still be on their servers. Floriva could not access your data even if it wanted to.
