Eve App Alternative: Private Period Trackers That Keep Data on Your Device

Eve by Glow Inc shares the same cloud infrastructure behind Glow's data breaches and California AG settlement. Here are eve period tracker alternatives with on-device storage.

Eve is built by Glow Inc, the same company that settled with the California Attorney General for $250,000 over unauthorized data sharing and whose API exposed data of approximately 25 million users. Eve runs on the same cloud infrastructure. Floriva keeps core records on your device and has no readable central cycle database.

Why Users Are Leaving Eve

Eve markets itself as a sex-positive period and health tracker. It is built by Glow Inc, the same company behind the Glow fertility app. This matters because Glow has one of the most documented privacy failure records in the period tracker category.

In September 2020, Glow settled with the California Attorney General for $250,000. The issue: Glow's Partner Connect feature automatically granted data access to anyone who sent a linking request, without the recipient confirming. Intimate health data, including miscarriage and abortion history, was exposed to unauthorized parties. Consumer Reports first discovered this vulnerability in July 2016. It took four years to reach a settlement.

In October 2024, security researcher Ovi Liber found an API bug exposing personal data of approximately 25 million Glow users, including names, age groups, location data, and images.

Eve shares the same parent company and cloud infrastructure. Users evaluating Eve's privacy should evaluate it against Glow Inc's full track record, not as a separate product.

What Eve Does With Your Data

Eve stores your period, health, and sexual activity data on Glow Inc's cloud servers. This creates the same exposure profile as Glow itself.

Server-stored data is accessible to the company and its partners, subject to policy changes the company can make at any time. It is also accessible through legal process, subpoenas, court orders, and law enforcement requests. For users in states with abortion restrictions, this is not a theoretical concern.

Mozilla's Privacy Not Included project reviewed Glow and found its privacy claims were "easily shown to be false." The same company governs Eve's data practices. When a company has a documented pattern of privacy failures in one product, the reasonable assumption is that its other products share the same governance standards.

There is no published documentation indicating Eve uses a different data architecture, different servers, or different privacy controls than Glow. Read more about how period tracker apps collect data and femtech data monetization.

What Changes When You Switch to On-Device Storage

On-device storage means your data is not on Glow Inc's servers. It is on your phone. No API vulnerability can expose it to researchers or attackers. No Partner Connect feature can share it without your knowledge. No subpoena can compel its disclosure from a server that does not exist.

Floriva uses local-first architecture. Core data (cycle dates, symptoms, predictions) is processed and stored locally. No account is needed for core tracking. Optional sync sends only end-to-end encrypted data that Floriva cannot read. The privacy guarantee is structural, not contractual. Learn about what zero-knowledge period tracking means.

How to Switch

Switching from Eve to Floriva:

Record your recent period dates and cycle lengths from Eve.
Install Floriva, no account or sign-up needed.
Enter your cycle history.
Delete your Eve / Glow Inc account and request data deletion.
Uninstall Eve.

Deleting your account matters. Uninstalling the app leaves your data on Glow Inc's servers. For a full comparison of private alternatives, see our list of best private period tracker apps.

The Privacy Bottom Line

Eve is Glow under a different name. Same company, same servers, same data governance. If Glow's $250,000 settlement, 25-million-user data exposure, and Mozilla's assessment of its privacy claims concern you, those concerns apply equally to Eve. The alternative is an app where the company never has your data in the first place.

Quick answers to the obvious questions.

Does Eve have the same privacy issues as Glow?

Eve is developed by Glow Inc, the same company behind the Glow app. Glow settled with the California Attorney General for $250,000 in September 2020 after its Partner Connect feature exposed intimate health data without user confirmation. In October 2024, an API bug exposed data of approximately 25 million Glow users. Eve shares the same parent company and infrastructure, which means the company's track record on data security applies to both products.

What happened with the Glow data breach?

In October 2024, security researcher Ovi Liber discovered an API vulnerability that exposed personal data of approximately 25 million Glow users, including names, age groups, location data, and images. Separately, in September 2020, Glow settled with the California AG for $250,000 over a Partner Connect feature that shared intimate health data without recipient confirmation. Consumer Reports first discovered that vulnerability in July 2016.
