Horiva vs Flo for Perimenopause: Privacy-First vs FTC Settlement

Last updated: March 21, 2026

TLDR

Horiva and Flo are built for different purposes. Flo is a fertility and period tracking app used by over 70 million people. Horiva is a perimenopause-specific tracker with on-device data storage. The core difference is what happens to your health data and whether the app was designed for your life stage.

Why the Comparison Matters

Flo is the most downloaded period-tracking app in the US. Women who start researching perimenopause trackers often start with Flo because it is already on their phone. The question they arrive at is whether a general-purpose fertility app is the right tool for perimenopause.

The answer depends on what you need from a tracker.

The Purpose-Built Difference

Flo was built for ovulation and fertility. The cycle prediction engine, the educational content, the community features — all of it is oriented toward women who want to understand fertility windows, track pregnancy, or manage contraception.

Horiva was built for a different phase of life. The symptom categories — hot flash intensity, night sweat patterns, brain fog severity, sleep quality — are the things that matter during perimenopause. There is no ovulation predictor because it is not relevant for most users.

The Data Privacy Record

Flo’s 2021 FTC settlement is the clearest data point in this comparison. The FTC found that Flo shared health data about pregnancy intentions and menstrual health with Facebook and Google without user consent. Flo had explicitly marketed itself as private.

Horiva’s approach is structural rather than policy-based. On-device storage means there is no server-side health database to share, sell, or breach. It is not a promise in a privacy policy — it is the architecture.

Doctor Appointments

Women in perimenopause often see multiple providers and need to communicate complex symptom patterns across appointments. Flo does not generate a report formatted for medical use. Horiva’s PDF export is designed for that specific use case — a timeline of symptoms, frequency, and severity that a gynecologist or endocrinologist can review in under two minutes.

Neither option feel right?

Most women pay for features they don't use. Horiva is $9/mo with no data selling — ever.

Verdict

Horiva is the stronger choice for women in perimenopause who want private, perimenopause-specific tracking. Flo is the stronger choice for women who want fertility and ovulation tracking with a free tier and are comfortable with the data practices documented in Flo's FTC settlement.

PROS & CONS

Horiva

Pros

  • Symptom framework designed for perimenopause transition — not adapted from fertility features
  • On-device encryption means Horiva cannot access, sell, or share your health data
  • PDF report export formats symptom data for doctor appointments

Cons

  • Paid-only model at $9/mo — no permanent free tier
  • Newer product with less established review history
  • Smaller dataset than established apps

PROS & CONS

Flo

Pros

  • Free tier accessible without subscription
  • Largest period-tracking user base provides extensive aggregate data
  • Strong fertility and ovulation prediction for regular cycles

Cons

  • FTC charged Flo in 2021 for sharing health data with Facebook and Google for advertising purposes without user consent
  • Perimenopause features layered onto a fertility product — predictions degrade with irregular cycles
  • Free tier data practices fund advertising revenue

Q&A

Is Horiva or Flo better for perimenopause?

Horiva is better for perimenopause tracking. Horiva was built specifically for the perimenopause transition — irregular cycles, hot flash patterns, sleep disruption, brain fog, and mood changes. Flo's core product is ovulation and fertility prediction, which becomes less accurate as perimenopause progresses. If perimenopause symptom tracking is your goal, Horiva's purpose-built design is a meaningful advantage.

Q&A

What happened with Flo's FTC settlement?

The FTC charged Flo Health in January 2021 with deceptive practices: Flo had promised users their health data was private, then shared it with Facebook's app analytics tool and Google's Firebase for advertising targeting without user consent. Flo settled, agreeing to notify affected users, delete improperly shared data from third parties, and undergo third-party privacy audits. Flo paid a $75,000 fine.

Q&A

Does Horiva have a free tier?

Horiva does not have a permanent free tier. There is a 14-day trial that requires no payment information upfront. After the trial, Horiva costs $9/month. The paid model is intentional — it removes the need for data monetization. There is no advertiser-funded tier and no research data-sharing arrangement.

Can I import my Flo data into Horiva?
Flo provides a data export in its Premium tier. Horiva does not currently have an automated import from Flo's export format. You can use your Flo history as a reference and begin tracking from the current date in Horiva.
Does Horiva track ovulation?
Horiva tracks cycle dates and irregular patterns but does not include a fertility-focused ovulation prediction engine. Horiva is designed for women in perimenopause, where ovulation prediction is less relevant and cycle tracking focuses on pattern recognition rather than fertility planning.
How does Horiva's on-device storage work?
Horiva stores all symptom data in encrypted local storage on your device. When you log a hot flash, sleep disruption, or mood change, that data is saved locally and never transmitted to Horiva's servers. Generating a doctor report creates a PDF on your device — the data does not pass through Horiva's infrastructure.
