Eve by Glow Pricing: What You Pay and What It Costs You

Eve by Glow shares Glow's pricing structure and Glow's data exposure history. Here is what the free and premium tiers actually cost.

Eve by Glow is free with ads and offers Glow Premium as a paid upgrade. Eve shares infrastructure with Glow, which exposed data for 25 million users through an API vulnerability in 2016 and faced a California AG enforcement action. The free tier funds itself through advertising; the premium tier removes ads but keeps data server-side.

Eve's Place in the Glow Ecosystem

Eve is one of several apps made by Glow Inc. The main Glow app targets fertility and pregnancy. Eve targets period and sex tracking with a more casual, community-focused approach. The branding is different. The backend is the same.

This matters because Glow's backend has a documented history. In 2016, Consumer Reports found an API vulnerability that exposed personal data for about 25 million users across Glow's apps. The California Attorney General took enforcement action. That vulnerability was in the same infrastructure Eve runs on.

When you evaluate Eve's pricing, you are also evaluating Glow's security track record.

The Free Tier

Eve's free tier offers period tracking, sex and intimacy logging, daily health insights, and community forums. It works for basic tracking. It is also ad-supported.

Ad SDKs are embedded in the app to serve targeted ads. Eve tracks especially sensitive data: not just cycle dates but sexual activity, partner details, and intimacy patterns. That data sits alongside ad SDKs built to build profiles about you.

Your sexual health tracking data and advertising code run in the same app.

Glow Premium

Glow Premium works across all Glow apps, including Eve. It removes ads and adds analytics features. Check the app store for the current price, as Glow has adjusted it over time.

Premium removes the ads you see. Your data stays on Glow's servers. Your account is still required. The 2016 vulnerability has been patched, but the cloud model that made it possible has not changed.

Paying for Premium buys a cleaner interface. It does not change where your data lives.

The Intimacy Data Problem

Most period trackers collect cycle dates, symptoms, and mood. Eve goes further. It actively encourages users to log sexual activity, orgasm details, partner information, and intimacy patterns. The community features are built around frank discussion of sex and health.

That openness is part of Eve's appeal. It is also part of the risk. This data on Glow's servers is one of the most intimate digital profiles a person can create. It combines reproductive health data with sexual behavior data in a single, server-stored, account-linked record.

In states with reproductive health restrictions, this combination matters. Cycle data can indicate pregnancy. Sexual activity data can indicate timing. Together, on a subpoena-accessible server, they create a detailed record outside your control.

Glow's Enforcement History

The 2016 Consumer Reports investigation and the California AG action showed that Glow's infrastructure had real security flaws. Millions of users' intimate health data was exposed. Glow fixed the specific vulnerability, but it shows the risk of trusting a third party with this kind of data.

Security requires ongoing effort. The question is whether you trust Glow's current practices with data this sensitive.

Floriva's Approach

Floriva is a paid app with no free tier. Core cycle records stay local-first on your device. No account is required for basic tracking. No advertising SDKs run in the app.

Floriva reduces company-side breach and legal-process exposure because it does not keep a readable central cycle database. Device access, exports, backups, billing, and support records are separate risks.

The Math

Eve is free and stores your sexual and reproductive health data on servers with a documented exposure history. Floriva is a paid app with no free tier and keeps core cycle records local-first on your device.

You pay with money or you pay with the most intimate data you create. There is no option that costs nothing.

What you actually pay over time.

Shared infrastructure with Glow: Eve runs on Glow's backend. Glow exposed data for 25 million users through an API vulnerability discovered by Consumer Reports in 2016. The California Attorney General took enforcement action. Eve users share this infrastructure risk.
Ad-SDK data collection on free tier: The free tier is ad-supported. Advertising SDKs collect behavioral data including usage patterns around cycle and sexual health tracking. This data flows to third-party ad networks.
Intimate data categories: Eve specifically tracks sexual activity, partner details, and intimacy patterns alongside cycle data. This is an unusually sensitive data combination to store on third-party servers accessible via legal process.

Quick answers to the obvious questions.

How much does Eve by Glow cost

Eve is free to download and use with ads. Glow Premium, which works across all Glow apps including Eve, removes ads and adds analytics features. Check the app store for current Premium pricing. The free tier is the primary product, funded by advertising.

Is Eve the same as Glow

Eve is a separate app made by Glow Inc. that focuses on period and sex tracking with a more casual tone than the main Glow fertility app. Both apps share backend infrastructure, the same Glow Premium subscription, and the same data handling practices. A security issue affecting Glow's infrastructure affects Eve users too.

Questions people ask before they switch.

What happened with Glow's data exposure

In 2016, Consumer Reports discovered an API vulnerability in Glow's systems that exposed personal data for approximately 25 million users. The California Attorney General subsequently took enforcement action against Glow. Eve shares this same backend infrastructure.

Does Glow Premium make Eve private

Glow Premium removes ads from Eve. It does not change where your data is stored (Glow's servers), whether an account is required (yes), or whether your data can be accessed via legal process (it can). Premium is an experience upgrade, not a privacy upgrade.

Why is Eve's data especially sensitive

Eve tracks sexual activity, partner information, and intimacy details alongside menstrual cycles. This combination of reproductive and sexual health data stored on third-party servers represents a uniquely sensitive data profile. In jurisdictions with reproductive health restrictions, this data could be legally compelled.
