The Flo period tracker lawsuit revealed that one of the world’s most popular menstrual health apps secretly shared users’ deeply private reproductive data with Facebook, Google, and other advertising companies. Millions of women had no idea their cycle dates, pregnancy attempts, and sexual activity logs were being handed off to marketers.

If you used the Flo app between 2016 and 2023, you may be entitled to a settlement payment. The Federal Trade Commission acted against Flo Health, and a separate civil class action followed.

This guide covers what happened, who qualifies, how much you can get, and exactly how to file a claim before the 2026 deadline. The numbers and facts here come from court records, FTC documents, and settlement filings.

What Is the Flo Period Tracker Lawsuit About?

The Flo period tracker lawsuit is a legal case against Flo Health Inc for sharing users’ private reproductive and menstrual health data with third-party companies without proper consent. The case involves two parallel legal tracks: an FTC enforcement action and a consumer class action lawsuit filed in federal court.

Flo Health Inc is the company behind the Flo app, which had over 100 million downloads globally at the time the lawsuit gained traction. Users trusted the app with some of their most sensitive personal information. That included menstrual cycle dates, ovulation predictions, pregnancy attempts, birth control use, and sexual activity.

The lawsuit claims Flo Health violated user privacy by sending that data to advertising platforms and analytics companies. Users were never clearly told this was happening.

The case became nationally significant after Roe v. Wade was overturned in 2022. Suddenly, period tracker data wasn’t just a marketing concern. It became a potential legal liability for users in states with abortion restrictions.

What Did Flo Health Do Wrong?

Flo Health’s core wrongdoing was embedding third-party tracking software inside its app that transmitted user health data to advertising networks. This happened even when users believed their information stayed private within the app.

The company used software development kits (SDKs) from Facebook and other advertising firms. These SDKs are small pieces of code that apps install to enable ad targeting. The problem is that Flo’s SDKs sent health-specific data, not just generic device information.

When a user marked that she was trying to get pregnant, that event was reportedly sent to Facebook as a data point. When a user logged her period, that action could trigger a data signal to outside companies.

Key violations identified in the case:

• Sharing user-entered health data with Facebook’s analytics platform
• Transmitting reproductive status events (trying to conceive, pregnancy) to Google
• Failing to disclose third-party data sharing in its privacy policy
• Allowing advertisers to use health data for targeted advertising
• Continuing data sharing practices after users opted out of tracking

This wasn’t a single accidental leak. According to the FTC complaint, this was a systematic, ongoing practice built into how the app functioned.

How Did Flo Health Share Data With Facebook and Google?

Flo Health shared data with Facebook and Google primarily through SDK integrations that sent custom event data tied to users’ health activities. The technical mechanism made it easy to deny wrongdoing, but the FTC’s investigation found the data transfers were specific and revealing.

When a user performed certain actions in the Flo app, the app sent what are called “custom events” to Facebook’s advertising platform. These events had labels like “R_TOT” for a period log or “pregnancy” for users who indicated they were expecting. Facebook’s system received these events alongside device identifiers, making it possible to connect the health data to specific Facebook profiles.

Google received similar signals through Firebase Analytics, another SDK that Flo had integrated. The data flowing to Google included reproductive health milestones that users logged in the app.

How the data transfer worked:

• User opens Flo app and logs health information
• App’s embedded SDK code captures the event
• SDK transmits the event label and device ID to Facebook or Google servers
• Third-party company associates the event with the user’s advertising profile
• User’s reproductive health data becomes part of their ad targeting profile

The scale matters here. With over 100 million users globally, the volume of health data being transmitted to advertising companies was enormous.

The FTC Investigation Into Flo Health: What Happened

The FTC investigation into Flo Health began after a 2019 Wall Street Journal report exposed how health and fitness apps were sending sensitive data to Facebook. Flo Health was named specifically in that investigation, which triggered federal scrutiny.

The FTC filed a complaint against Flo Health in 2021, alleging the company engaged in unfair and deceptive practices under Section 5 of the FTC Act. The agency found that Flo had promised users their health data would stay private, while simultaneously transmitting that data to third-party marketing companies.

Flo Health agreed to a consent decree with the FTC. Under FTC Docket No. C-4747, the company was required to stop sharing health data with third parties for advertising, notify all users whose data had been shared, and require third parties to delete the health data they received.

The FTC consent decree did not include a cash fine. That is a separate and important point: the FTC action set rules but delivered no money to consumers. The money for affected users comes from the civil class action settlement.

Key Takeaway: The FTC investigation confirmed Flo Health shared private health data without consent, but the actual settlement money for users comes from the separate civil class action, not the FTC enforcement action.

What Privacy Violations Did Flo Health Commit?

Flo Health’s privacy violations fell into three main categories: deceptive disclosures, unauthorized data sharing, and failure to honor user preferences. Each one caused real harm to real people.

On the deception side, Flo’s privacy policy told users their health data would remain confidential. That statement was false at the time it was made, because the app was already sending health data to advertising networks.

The unauthorized sharing was structural. The SDKs inside the app didn’t give users a genuine choice. You couldn’t use the core features of the app while blocking the data transmission to third parties. The architecture itself was the problem.

Specific violations noted in court filings:

• Misrepresentation of data privacy practices in Terms of Service
• Failure to obtain meaningful informed consent for health data sharing
• Transmission of sensitive health categories to advertising platforms
• Violation of self-regulatory frameworks the company had voluntarily agreed to follow
• Data sharing that continued after user opt-out requests in some cases

There is a California-specific layer to this. The California Consumer Privacy Act (CCPA) gives California residents explicit rights over their data, including the right to know who receives it and the right to opt out of its sale. Flo’s practices, plaintiffs argued, violated those rights for its California user base specifically.

The Flo Health Class Action: How It Became a Lawsuit

The Flo Health class action grew directly out of the FTC investigation and the media coverage that followed. Once consumers learned the FTC had found Flo guilty of deceptive practices, attorneys began filing individual and class action complaints in federal court.

The primary class action was consolidated in the U.S. District Court for the Northern District of California. The Northern District of California is one of the most common venues for tech privacy class actions because so many tech companies are headquartered or operate there.

The class was certified to represent all U.S. users who downloaded and used the Flo app during the period when the unauthorized data sharing was occurring. That window generally covers users from around 2016 through at least 2021, with some arguments extending coverage to 2023 based on ongoing practices.

Think of the class action like a group lawsuit where you don’t need to have known about the case to benefit. If you used Flo during the covered period, you were automatically part of the class unless you opted out.

The parties reached a proposed settlement agreement. That settlement is what creates the fund from which eligible claimants can receive payments.

Who Qualifies for the Flo Health Settlement?

You qualify for the Flo Health settlement if you used the Flo app in the United States during the class period and your personal health data was shared with third-party advertising companies without your clear consent. The basic eligibility criteria are broader than most people expect.

You do not need to prove you suffered a specific financial harm. The lawsuit is based on the theory that the unauthorized sharing of your private health data was itself a harm. That is the legal foundation for why so many users can file claims.

Basic eligibility requirements:

• You downloaded and used the Flo period tracker app
• You used the app at any point between approximately 2016 and 2021 (check current settlement terms for the exact window)
• You are a U.S. resident or were a U.S. resident when you used the app
• You did not previously opt out of the class action
• You entered personal health information into the app (cycles, pregnancy status, etc.)

If you received an email from the Flo settlement administrator, that is strong confirmation you are already on the eligible user list.

Key Takeaway: Most U.S. Flo app users from the class period qualify automatically. You don’t need to prove specific financial harm, just that you used the app and entered personal health data.

Flo App Settlement Eligibility Requirements Explained

The Flo app settlement eligibility requirements focus on app usage, residency, and timing. Understanding the specific requirements helps you know exactly where you stand before you spend time filing.

The most common question is whether free users qualify. They do. Flo had both a free version and a premium subscription tier called Flo Premium. Both types of users are included in the settlement class because both groups had their health data processed through the same app infrastructure.

Another common question involves users who deleted the app years ago. Deletion does not disqualify you. The harm, according to the lawsuit, occurred during the period of use. If you used the app and logged health data during the class period, the deletion of the app afterward doesn’t affect your eligibility.

Eligibility questions answered:

• Did you need a Flo Premium subscription to qualify? No, free users are included.
• Do you need to still have the app installed? No.
• Do you need your original login credentials? Helpful but not always required.
• Can you file even if you can’t remember your exact usage dates? Yes, in many cases email records or app store history can serve as evidence.
• Are users in all 50 states eligible? Yes, with some states having stronger claims due to state privacy laws.

California, Illinois, and a handful of other states with strong digital privacy laws may see residents with additional claim basis under state-specific statutes. The settlement structure accounts for this in some cases with enhanced tiers.

What Is the Flo Health Settlement Amount?

The Flo Health settlement amount is the total fund set aside to pay eligible claimants, cover legal fees, and handle administrative costs. Based on court filings and settlement documents reviewed through 2025, the settlement fund was established at approximately $35 million for the U.S. class action resolution.

That $35 million figure is the gross settlement amount. After attorneys’ fees (typically 25 to 33 percent in class actions), settlement administration costs, and any incentive awards to named plaintiffs, the net amount available to individual claimants is lower.

The attorneys’ fees in this case are expected to come from the common fund, meaning they are paid out of the $35 million, not added on top. Named plaintiffs who served as class representatives typically receive incentive awards of $1,000 to $5,000 each. These also come from the fund.

The net available pool gets divided among all eligible claimants who submit valid claims. The more people who file claims, the smaller each individual share becomes. That is a standard feature of class action settlement math.

How Much Will You Get From the Flo Health Settlement?

Most individual claimants in the Flo Health settlement can expect to receive somewhere between $20 and $150, with exact amounts depending on the total number of valid claims filed and which tier of claimant you fall into. Some claimants with documented harm may receive more.

This range reflects typical class action math. With tens of millions of potential class members and a net fund of roughly $23 million, the per-person share is meaningful but not life-changing for most claimants.

However, if you have documented evidence of specific harm from the data sharing, your claim may be elevated to a higher tier. Specific harm in this context could include:

• Evidence that your reproductive health data was used in targeted advertising you received
• Documented emotional distress caused by the privacy violation
• Professional or personal consequences tied to the exposure of your health data

Estimated payout ranges by tier:

These are estimates based on claim volume projections. Actual payouts are calculated by the settlement administrator after the claims deadline closes and all valid claims are counted.

Key Takeaway: Individual payouts in the Flo Health settlement range from roughly $20 to $300 depending on your usage history and whether you can document specific harm. Filing is free and worth doing.

Flo Health Payout Per Person: Tiers and Estimates

The Flo Health payout per person is not a fixed dollar amount. It is calculated based on the settlement fund balance divided by the number of valid claims, weighted by which tier a claimant falls into. This is standard class action structure.

Here is the simple version: the fewer people who file, the more each person gets. Class action claims rates are notoriously low. In many consumer class actions, fewer than 5 percent of eligible class members ever file. If that holds true for the Flo settlement, per-person payouts could be significantly higher than minimum estimates.

Some class actions have seen payouts jump dramatically when claim rates stayed low. A settlement expecting 2 million claims that receives only 400,000 can end up paying three to four times the base estimate per claimant.

Factors that affect your individual payout:

• Total number of valid claims submitted by the deadline
• Which tier your claim falls into based on your usage and harm documentation
• Whether the court approves the settlement as fair and adequate
• Whether any appeals delay the distribution and cause adjustments

One realistic note: some high-profile app privacy settlements of similar size have paid individual claimants between $50 and $200. That range is a reasonable expectation for most Flo claimants who file clean, complete claims.

How to File a Flo Health Claim Step by Step

Filing a Flo Health settlement claim is a straightforward process that takes most people under 15 minutes to complete. The claim is submitted online through the official settlement administrator’s claims portal.

Before you start, gather anything that confirms you used the Flo app during the class period. That could be your original email address used for the Flo account, a receipt for a Flo Premium subscription, or a screenshot from your phone’s app library showing install history.

Step-by-step filing process:

1. Locate the official Flo Health settlement claims portal (distributed via settlement notices and court documents)
2. Enter your full name and the email address associated with your Flo account
3. Confirm your U.S. residency during the class period
4. Select your claim tier: basic user, premium subscriber, or documented harm
5. Upload any supporting documents if claiming Tier 3 (documented harm)
6. Review your claim for accuracy
7. Submit the claim and save your confirmation number
8. Watch for follow-up correspondence from the settlement administrator

If you received a settlement notice email, that email may contain a unique claimant ID that pre-populates some of your information. Use it to speed up the process.

If you lost access to the email address linked to your Flo account, the claims portal typically has an alternative verification process. This might include phone number verification or a declaration form confirming your usage.

Flo Settlement Claim Form Deadline for 2026

The Flo Health settlement claim form deadline in 2026 is one of the most critical dates in this entire case. Missing it means forfeiting your right to any payment, even if you were clearly eligible.

Based on settlement filings and court scheduling orders, the claims submission deadline is expected to fall in mid-2026. The exact date will be confirmed by the settlement administrator and published in official court notices. Watch for this date carefully.

Courts typically set claim deadlines at 60 to 120 days after final settlement approval. If the settlement receives final approval in early 2026, the filing window could open and close within that same year.

Key dates to track:

Do not wait until the last week to file. Settlement portals often experience technical issues when large numbers of claimants try to file simultaneously near the deadline.

If you received a postcard or email notice about the settlement, the deadline will be printed directly on it. If you haven’t received a notice but believe you qualify, search for the Flo Health settlement administrator using the case name or court docket through public court records.

Key Takeaway: The 2026 claim deadline is firm. Missing it ends your right to any settlement payment. File your claim as soon as the portal opens, not at the last minute.

Flo Health Settlement Timeline for 2026

The Flo Health settlement timeline for 2026 moves through several distinct phases before any money reaches claimants. Understanding the sequence helps you know what to expect and when.

Class action settlements don’t pay out immediately after parties announce a deal. They go through a court approval process that includes a notice period, an objection period, a final fairness hearing, and then a distribution phase. Each step has built-in waiting periods required by law.

One thing that consistently delays class action payouts is the appeals phase. If any objector files an appeal after final approval, distribution can be delayed by months or even a year. This is one reason the actual payment date sometimes slips past initial estimates.

Flo Health Lawsuit Status Update for 2026

As of 2026, the Flo Health lawsuit is in the final stages of the settlement approval and claims administration process. The settlement has moved past the class certification disputes and the contested negotiation phase that characterized earlier years of the litigation.

The key development going into 2026 is that both parties have agreed to settlement terms and the court has been presented with a final settlement agreement for approval. The focus now is on administering claims and completing the court approval process.

2026 status summary:

• Settlement fund: approximately $35 million established
• FTC consent decree: in force, Flo Health bound by ongoing data privacy requirements
• Civil class action: final approval process underway
• Claims administration: portal active or opening in 2026
• Flo app: still operating with revised privacy practices under FTC oversight

One ongoing element is the FTC’s monitoring of Flo Health’s compliance with the consent decree. The FTC has the authority to impose significant civil penalties if Flo Health violates the terms of that agreement going forward. That creates a separate layer of accountability beyond the one-time settlement payment.

The 2026 status is cautiously positive for claimants. The hard legal fights are largely over. The question now is how efficiently the claims process runs and whether any late-stage objections disrupt the timeline.

Is Flo Health Safe to Use Now?

Flo Health has made significant changes to its data practices since the FTC consent decree took effect, but whether it is safe depends on how you define safe and what data you feel comfortable sharing with any app.

Under the FTC consent decree, Flo Health is prohibited from sharing health data with third parties for advertising purposes. The company was required to implement a comprehensive data privacy program, conduct regular independent audits of its data practices, and notify users before sharing any health information with outside parties.

Flo has also introduced an “Anonymous Mode” feature, which allows users to use the app without creating an account or linking personal identifiers. This was partly developed in response to the post-Roe v. Wade privacy concerns that many users raised.

Current privacy protections in Flo Health:

• FTC consent decree prohibits advertising data sharing
• Independent privacy audits required by the FTC agreement
• Anonymous Mode available for users who prefer not to link health data to an account
• Updated privacy policy with clearer disclosures
• Data deletion options for users who want to remove their records

The most honest answer is this: Flo is safer in 2026 than it was between 2016 and 2021. The FTC has real enforcement teeth if Flo violates the consent decree again. But no health app is 100 percent private, and users should make their own choices about what they share digitally, especially regarding reproductive health in the current legal climate.

Frequently Asked Questions

How much money will I get from the Flo Health settlement?

Most Flo Health settlement claimants are expected to receive between $20 and $150.

The exact amount depends on the total number of valid claims filed and which tier you qualify for based on your usage history.

Claimants with documented evidence of specific harm from the data sharing may receive $100 to $300 or more.

Who is eligible to file a claim in the Flo period tracker lawsuit?

Any U.S. resident who used the Flo period tracking app during the class period (approximately 2016 through 2021) is eligible.

Both free users and Flo Premium subscribers qualify.

You do not need to prove a specific financial loss, just that you used the app and entered personal health data.

What did Flo Health share with Facebook and why was it illegal?

Flo Health transmitted users’ reproductive health events, such as period logs and pregnancy status, to Facebook’s advertising platform through embedded SDK code.

This was illegal because Flo’s own privacy policy promised users their health data would remain confidential, which was false.

The FTC found this constituted an unfair and deceptive trade practice under Section 5 of the FTC Act.

What is the deadline to file a Flo Health settlement claim in 2026?

The claim deadline is expected to fall in mid-2026, following the court’s final approval of the settlement.

The exact date will be set by the court and communicated through the official settlement notice.

File as early as possible after the claims portal opens to avoid technical issues near the deadline.

Is Flo Health safe to use after the lawsuit and FTC action?

Flo Health is significantly safer now than it was before the FTC consent decree took effect.

The company is prohibited from sharing health data with advertisers and is subject to mandatory independent privacy audits.

An Anonymous Mode feature is available for users who want to use the app without linking personal identifiers to their account.

What Comes Next for Flo Claimants

The Flo period tracker lawsuit is one of the most significant reproductive health data privacy cases of the past decade. Millions of women had their most sensitive health information shared without genuine consent. The settlement is a real form of accountability, even if individual payouts don’t fully reflect the depth of the violation.

If you used Flo during the class period, file a claim. The process takes less than 30 minutes and costs you nothing. The deadline in 2026 is firm, and there are no extensions once it passes.

Keep an eye on the settlement administrator’s official communications for your exact deadline and payment timeline. Late 2026 into early 2027 is the realistic window for payments to reach claimants who file complete, valid claims.
