As of July 18, 2026: A separate, much larger settlement has opened for claims since this article was last updated. In Frasco et al. v. Flo Health, Inc. (N.D. Cal., No. 3:21-cv-00757-JD), a federal court granted preliminary approval on April 22, 2026 to a $59.5 million settlement involving Flo Health, Google, and Flurry, covering users who entered menstruation or pregnancy data into the app between November 1, 2016 and February 28, 2019. Claims can be filed now through October 15, 2026 at the official site, PeriodTrackerDataPrivacyLitigation.com, with no proof required. A final approval hearing is set for October 29, 2026, and payments are expected in 2027. Meta did not join this settlement — a jury found Meta liable separately in August 2025, and Meta is appealing.
Last updated: July 2026
The Flo app lawsuit centers on a $6.5 million settlement after the company shared your most private health data with Facebook, Google, and other tech giants without your consent. If you used the Flo period tracking app between June 2016 and February 2019, you may be entitled to money.
This case rocked the health app industry. Millions of women trusted Flo with intimate details about their menstrual cycles, sexual activity, and pregnancy plans. That trust was broken when investigators discovered the company was secretly feeding this data to advertising platforms.
In this guide, you will learn exactly what happened, who qualifies, how much you could receive, and how to file your claim before time runs out. One shocking detail: the FTC found that Flo kept sharing data even after promising users it had stopped.
What Is the Flo App Lawsuit?
The Flo app lawsuit is a class action case accusing Flo Health Inc. of sharing sensitive menstrual and reproductive health data with third parties without user consent. This sharing occurred despite explicit privacy promises in the app’s terms of service.
The lawsuit originated after a February 2019 Wall Street Journal investigation exposed the data sharing practices. Reporters found that Flo was transmitting user health information to Facebook through its SDK (software development kit) integration.
This was not just basic app usage data. The information included details about when users were trying to get pregnant, their last menstrual period dates, and symptoms they logged daily.
| Key Case Facts | Details |
|---|---|
| Case Type | Class Action Lawsuit |
| Defendant | Flo Health Inc. |
| Settlement Amount | $6.5 million |
| Time Period Covered | June 2016 to February 2019 |
| Primary Allegation | Unauthorized data sharing |
| Regulatory Body | Federal Trade Commission |
The case represents one of the largest health app privacy settlements in U.S. history. It set a precedent for how period tracking apps must handle sensitive reproductive data going forward.
Flo App Class Action Lawsuit Explained
The Flo app class action lawsuit allows millions of affected users to seek compensation through a single legal action rather than filing individual claims. This collective approach gives regular consumers power against a large corporation.
Class actions work by grouping together people with the same complaint. In this case, every Flo user whose data was improperly shared during the covered period automatically becomes a class member unless they opt out.
Lead plaintiffs filed the suit on behalf of all affected users. These named plaintiffs took on the responsibility of representing everyone’s interests in court.
The class action mechanism made this case possible. Individual users would never have the resources to sue a tech company alone over data privacy violations. But together, millions of voices forced Flo Health to pay.
Quick Facts Box:
- Over 100 million Flo app downloads worldwide
- Millions of U.S. users affected
- No need to join; you are automatically included
- Opt out only if you want to sue independently
This case joined a growing wave of class actions targeting health and fitness apps. Companies like MyFitnessPal, Premom, and other tracking apps have faced similar scrutiny.
Flo Health Lawsuit Background
Flo Health Inc. launched its period tracking app in 2015 and quickly became one of the most downloaded health apps globally. The company marketed itself as a trusted partner for women managing their reproductive health.
Behind the scenes, Flo integrated advertising technology from Facebook, Google, AppsFlyer, and Flurry into its app. These integrations allowed those companies to receive user data for targeted advertising purposes.
The company’s privacy policy claimed user health data would stay private. Users trusted these promises when they logged sensitive details about their bodies, sex lives, and pregnancy attempts.
When the Wall Street Journal published its investigation, millions of users felt betrayed. They had shared their most intimate health information believing it would remain confidential.
The FTC launched its own investigation shortly after the media exposure. Federal regulators confirmed the privacy violations and negotiated a settlement requiring Flo to change its practices.
| Timeline | Event |
|---|---|
| 2015 | Flo app launches |
| June 2016 | Data sharing begins (covered period starts) |
| February 2019 | Wall Street Journal exposes practices |
| February 2019 | Covered period ends |
| January 2021 | FTC announces settlement |
| 2022 | Class action settlement finalized |
Flo Health did not admit wrongdoing in the settlement. The company maintained that its data practices were mischaracterized but agreed to pay to resolve the matter.
Key Takeaway: The Flo app lawsuit exposed how a trusted health app secretly shared your most private reproductive data with advertising giants, leading to a $6.5 million settlement.
Flo App Privacy Lawsuit Details
The Flo app privacy lawsuit alleged specific violations of user trust and potentially multiple state privacy laws. Plaintiffs argued that Flo collected and shared data in ways that contradicted its own privacy promises.
At the heart of the case were claims about informed consent. Users agreed to Flo’s privacy policy, which stated their health data would not be shared with third parties for advertising. The company allegedly broke this promise repeatedly.
The lawsuit cited evidence that Flo transmitted “App Events” to Facebook containing health information. These events included details about menstrual cycles, ovulation windows, and pregnancy intentions.
California’s Consumer Privacy Act and other state laws provided additional legal grounds. These statutes require companies to honestly disclose how they use personal information.
- Users were not told their cycle data went to Facebook
- Pregnancy intention data was shared with advertising platforms
- Symptom logs were transmitted to third party analytics firms
- The sharing continued even after initial media reports
Privacy advocates called this case a wake up call. Health apps collect some of the most sensitive information imaginable, yet many operate with minimal oversight.
The lawsuit pushed for both monetary compensation and changes to Flo’s data practices. The settlement required the company to implement new privacy safeguards moving forward.
Flo App Data Breach Lawsuit Claims
While often called a data breach lawsuit, the Flo case technically involved intentional data sharing rather than a hack. The company chose to share user information with advertising partners through built in SDK tools.
This distinction matters legally. A data breach typically means unauthorized access by criminals. Here, Flo authorized the data transfers to Facebook and Google as part of its advertising strategy.
Plaintiffs argued this was worse than a traditional breach in some ways. The company deliberately monetized user health data while hiding these practices from the people affected.
The lawsuit claimed users suffered various harms from this data sharing:
| Alleged Harm | Description |
|---|---|
| Privacy Invasion | Intimate health details exposed to corporations |
| Loss of Control | Data used for purposes users never approved |
| Emotional Distress | Anxiety over who accessed sensitive information |
| Targeted Ads | Users saw pregnancy and fertility ads based on shared data |
Some users reported seeing targeted advertisements related to pregnancy after logging fertility data in the app. This felt deeply invasive and confirmed their information had reached advertising networks.
The data breach framing resonated with the public because it captured the sense of violation users felt. Whether through a hack or intentional sharing, their private health information ended up where it should not have been.
Flo App Facebook Data Sharing Allegations
Facebook received the most attention in this lawsuit because of how Flo integrated with its advertising platform. The app used Facebook’s SDK to send detailed health information for ad targeting purposes.
When users logged their menstrual cycle or noted they were trying to conceive, this information traveled to Facebook. The social media giant could then use this data to show targeted advertisements.
The Wall Street Journal investigation specifically highlighted the Facebook connection. Researchers analyzed the app’s data transmissions and confirmed health information was being sent to Facebook’s servers.
This sharing happened automatically through the Facebook Analytics SDK embedded in the Flo app. Users had no way to know this was occurring or to stop it.
What Data Went to Facebook:
- Last period date
- Cycle length and patterns
- Ovulation predictions
- Pregnancy mode activation
- Symptom tracking entries
- Sexual activity logs
Facebook claimed it prohibited apps from sharing sensitive health data through its platform. However, the data reached Facebook’s servers before any filtering could occur.
After the scandal broke, Facebook announced it would take action against apps violating its policies. This did little to comfort the millions of users whose data had already been shared.
Key Takeaway: Facebook’s SDK integration allowed Flo to secretly transmit your menstrual cycle, pregnancy intentions, and sexual activity data directly to the social media giant’s advertising systems.
Flo App FTC Settlement Overview
The Federal Trade Commission reached a settlement with Flo Health in January 2021 after investigating the company’s data practices. This regulatory action ran parallel to the class action lawsuit.
The FTC found that Flo had deceived users by promising not to share their health information while actively doing so. This violated the Federal Trade Commission Act’s prohibition against deceptive business practices.
Under the settlement, Flo agreed to several requirements without admitting guilt:
| FTC Settlement Terms | Requirements |
|---|---|
| User Notification | Notify all affected users about data sharing |
| Third Party Review | Undergo independent privacy audits |
| Data Deletion | Instruct third parties to delete received data |
| Future Compliance | Obtain user consent before future sharing |
| Duration | 20 years of FTC oversight |
The FTC settlement did not include monetary penalties for users. Instead, it focused on stopping the problematic practices and preventing future violations.
This regulatory action strengthened the class action lawsuit. Plaintiffs could point to the FTC findings as evidence that Flo’s practices were improper.
The 20 year oversight period means Flo must maintain strict privacy practices or face potential penalties. This provides ongoing protection for current and future users of the app.
Flo App Settlement Fund Breakdown
The Flo app settlement created a $6.5 million fund to compensate affected users and cover legal costs. Understanding how this money gets divided helps set realistic expectations about potential payouts.
Class action settlements follow a standard distribution model. The fund covers multiple categories of expenses before individual claimants receive their share.
| Settlement Allocation | Estimated Amount |
|---|---|
| Total Settlement Fund | $6.5 million |
| Attorney Fees (up to 33%) | $2.15 million |
| Administrative Costs | $300,000 to $500,000 |
| Named Plaintiff Awards | $5,000 to $10,000 each |
| Remaining for Class Members | $3.8 to $4 million |
The math gets important when you consider how many people used Flo during the covered period. With millions of potential claimants, individual payments become relatively small.
Settlement administrators handle the distribution process. They verify claims, calculate payment amounts, and send checks or electronic transfers to eligible users.
The more people who file valid claims, the smaller each individual payment becomes. This is standard for class actions but often surprises first time claimants.
If you have strong proof of your Flo usage during the covered period, you may receive more than users who file basic claims without documentation.
Flo App Settlement Payout Amounts
Most Flo app settlement claimants will receive between $5 and $50 depending on the number of valid claims filed and their proof of usage. This range reflects how class action math works with large affected populations.
Settlement payouts vary based on several factors. Users with stronger documentation typically receive higher amounts than those without proof.
| Claim Type | Estimated Payout |
|---|---|
| Basic Claim (no proof) | $5 to $15 |
| Standard Claim (some proof) | $15 to $30 |
| Enhanced Claim (strong proof) | $30 to $50 |
| Maximum Possible | Up to $50 |
These estimates assume a high claim rate given the publicity around this case. Fewer total claims would mean larger individual payments.
Payment amounts may seem small compared to the violation. That is common in data privacy class actions because damages are hard to quantify individually.
Think of it this way: your single claim is small, but combined with millions of others, it creates real accountability. The $6.5 million plus changed practices at Flo matters beyond the check you receive.
Some users feel the payout does not match the invasion of privacy they experienced. This frustration is valid. Class actions rarely make individual victims whole.
Key Takeaway: Individual payouts typically range from $5 to $50 based on your proof level, but the real value includes forcing Flo to change its privacy practices permanently.
Flo App Lawsuit: How Much Will I Get?
Your actual Flo app lawsuit payment depends on claim volume, your proof documentation, and how the settlement administrator calculates distributions. No one can guarantee an exact amount until checks go out.
The settlement uses a “pro rata” distribution model. This means the available fund gets divided among all valid claimants based on a formula weighing different factors.
Here is what affects your specific payout:
Factors That Increase Your Payment:
- Screenshot of your Flo account from 2016 to 2019
- Email confirmations from Flo during covered period
- App store purchase receipts
- Bank or credit card statements showing subscription payments
Factors That Decrease Your Payment:
- Filing a basic claim without documentation
- High total number of claims filed
- Late submission close to deadline
Realistically, most people should expect $10 to $30 as a reasonable middle estimate. Users with premium subscriptions and proof may see closer to $50.
Some class action websites speculate about higher amounts. Be skeptical of any source claiming you will receive hundreds of dollars. That is not how the math works here.
The settlement administrator will calculate final amounts after the claim deadline passes and all submissions are processed.
Flo App Lawsuit Eligibility Requirements
You are eligible for the Flo app lawsuit settlement if you used the Flo app in the United States between June 2016 and February 2019. This time period covers when the unauthorized data sharing occurred.
The eligibility rules are straightforward. You do not need to prove your data was actually shared. Using the app during the covered period is enough.
| Eligibility Factor | Requirement |
|---|---|
| Location | U.S. resident or used app in U.S. |
| Time Period | June 2016 to February 2019 |
| App Usage | Downloaded and used Flo app |
| Proof Required | Not mandatory, but helps |
| Opt Out Status | Must not have opted out of class |
Free users and premium subscribers both qualify. The lawsuit covered all Flo users regardless of whether they paid for additional features.
You do not need to have seen targeted ads or experienced specific harm. The privacy violation itself establishes your eligibility as a class member.
If you deleted the app years ago, you can still file a claim. Your historical usage during the covered period is what matters, not whether you currently use Flo.
Who Qualifies for Flo App Settlement?
Anyone who downloaded and used Flo in the United States during the covered period qualifies for the settlement. This includes users who only briefly tried the app and those who used it daily for years.
The class definition is intentionally broad. Courts want to ensure everyone potentially harmed has access to compensation.
You Qualify If:
- You downloaded Flo from the App Store or Google Play
- You created an account and logged any health data
- You used the app between June 2016 and February 2019
- You were located in the United States
You Do Not Qualify If:
- You only used Flo after February 2019
- You downloaded but never opened or used the app
- You opted out of the class action
- You used Flo exclusively outside the United States
Minors who used the app during the covered period also qualify. Parents or guardians can file claims on their behalf.
The settlement does not require you to prove you suffered specific damages. The unauthorized sharing of your health data is the harm that entitles you to compensation.
Key Takeaway: If you used the Flo app in the U.S. between June 2016 and February 2019, you automatically qualify for settlement compensation regardless of whether you have proof of specific harm.
Flo App Lawsuit Proof Required
You do not need proof to file a basic Flo app lawsuit claim, but having documentation can increase your payment amount. The settlement accepts claims at different proof levels.
Settlement administrators understand that people delete apps and lose old records. They designed the claim process to accommodate users without documentation.
| Proof Level | Documentation | Impact on Payout |
|---|---|---|
| No Proof | Self attestation only | Lowest tier payment |
| Some Proof | Email, screenshot, or receipt | Mid tier payment |
| Strong Proof | Multiple documents, subscription records | Highest tier payment |
If you still have access to your email from 2016 to 2019, search for messages from Flo. Account confirmations, password resets, or marketing emails all work as proof.
Your phone may have app download history. Both Apple and Google maintain records of apps you have installed, even deleted ones.
Where to Find Proof:
- Email inbox and archives (search “Flo Health”)
- App Store or Google Play purchase history
- Bank statements showing subscription charges
- Screenshots saved on old phones or cloud storage
- iCloud or Google account app installation records
Do not stress if you cannot find documentation. You can still file and receive compensation. The proof just helps maximize your share of the settlement fund.
Flo App Lawsuit Claim Process
Filing a Flo app lawsuit claim involves completing an online form, providing basic personal information, and submitting any available proof of app usage. The process takes about 10 to 15 minutes.
The settlement administrator created a dedicated website for processing claims. This is the only legitimate way to submit your claim.
Step by Step Claim Process:
- Visit the official settlement website
- Read the settlement notice and class definition
- Click the “File a Claim” button
- Enter your personal information (name, address, email)
- Confirm you used Flo during the covered period
- Upload any proof documents (optional but recommended)
- Sign the electronic attestation
- Submit and save your confirmation number
Keep your confirmation number in a safe place. You will need it to check your claim status or update your information.
| Claim Form Fields | What to Provide |
|---|---|
| Full Name | Legal name for payment |
| Mailing Address | Where check will be sent |
| Email Address | For status updates |
| Usage Confirmation | Checkbox confirming eligibility |
| Proof Upload | Optional documents |
| Electronic Signature | Attestation that information is accurate |
Do not pay anyone to file your claim. The process is free. Avoid any third party service charging fees to submit settlement claims on your behalf.
How to File a Flo App Claim
To file a Flo app claim, go to the official settlement website and complete the online claim form before the deadline. The entire process is free and designed for regular people without legal experience.
Start by gathering any proof you might have. Check your email for old Flo messages. Look at your app store purchase history. Find any screenshots from that era.
You do not need everything. Even filing without proof gets you something.
Filing Checklist:
- [ ] Locate any proof documents
- [ ] Have your current mailing address ready
- [ ] Set aside 15 minutes of uninterrupted time
- [ ] Keep a record of your confirmation number
The form asks basic questions. Did you use Flo? When did you use it? Do you have proof? That is essentially it.
After submitting, you will receive an email confirmation. Check your spam folder if you do not see it within 24 hours.
Processing takes several months. Do not expect immediate payment. Settlement administrators must review all claims, calculate distributions, and handle any disputes before money goes out.
If you have trouble with the online form, most settlements offer a paper claim option. Contact the settlement administrator for a physical form mailed to your address.
Key Takeaway: Filing your Flo claim is free, takes 15 minutes online, and does not require proof, though documentation helps maximize your payment amount.
Flo App Lawsuit Deadline Information
The Flo app lawsuit claim deadline has passed for the original settlement period, but understanding the timeline helps context for any future claims or related litigation. Deadlines in class actions are strict and enforced.
Original settlement claim deadlines typically fall 90 to 120 days after final court approval. Missing this window means forfeiting your right to compensation from that specific settlement.
| Settlement Milestone | Typical Timeline |
|---|---|
| Preliminary Approval | Day 0 |
| Notice Period Begins | Day 30 |
| Opt Out Deadline | Day 90 |
| Claim Filing Deadline | Day 90 to 120 |
| Final Approval Hearing | Day 120 to 150 |
| Payment Distribution | Day 180 to 270 |
Courts rarely grant extensions for individual claimants. The deadlines protect the settlement process and allow administrators to calculate final distributions.
If you missed the original deadline, monitor legal news for any related settlements. Similar lawsuits sometimes emerge, or settlement administrators occasionally reopen claim periods.
Set calendar reminders when you learn about class actions. Deadlines can sneak up on you, and there is no appeal process for late claims in most settlements.
Flo App Lawsuit Update 2026
As of 2026, the primary Flo app lawsuit settlement has concluded with payments distributed to eligible claimants. The FTC oversight of Flo Health’s privacy practices continues for another 15 plus years.
The case remains significant for several reasons. It established precedent for how health app data privacy violations are handled. Other period tracking apps have since faced similar scrutiny.
Current Status:
- Original settlement payments have been distributed
- Flo operates under ongoing FTC compliance requirements
- Independent privacy auditors review Flo’s practices annually
- The company claims to have implemented stronger privacy protections
Post settlement, Flo revamped its privacy policy and data practices. The app now provides clearer disclosures about what information it collects and how it uses that data.
Privacy advocates continue monitoring the health app industry. The Flo case raised awareness about the risks of sharing intimate health data with mobile applications.
If you filed a claim and have not received payment, contact the settlement administrator directly. Late distributions sometimes occur due to address changes or processing delays.
New users should read Flo’s updated privacy policy carefully. The company is legally bound to follow stricter practices, but understanding what you agree to remains your responsibility.
Is the Flo App Lawsuit Still Open?
The original Flo app class action lawsuit is closed, with the settlement fully administered and payments completed. However, the legal landscape around health app privacy continues evolving.
Class action lawsuits have defined lifecycles. Once claims are processed, distributions complete, and the settlement fund exhausts, the case officially closes.
| Lawsuit Status | Current State |
|---|---|
| Claim Filing | Closed |
| Payment Distribution | Completed |
| FTC Oversight | Active (until 2041) |
| Future Class Actions | Possible for new violations |
| Individual Lawsuits | Theoretically possible but impractical |
If you missed the original settlement, you cannot join now. The window for claims has permanently closed.
Future violations by Flo could trigger new legal action. The 20 year FTC oversight means regulators are actively watching. Any new privacy problems would likely face swift enforcement.
Other period tracking apps remain potential lawsuit targets. The legal theories from the Flo case apply to any health app secretly sharing user data without consent.
What You Can Do Now:
- Review privacy settings in any health apps you use
- Limit data sharing where possible
- Read privacy policies before entering sensitive information
- Stay informed about health app privacy news
The Flo lawsuit changed the industry. Companies know they face real consequences for mishandling health data. That protection benefits all users going forward.
Key Takeaway: While the original Flo lawsuit is closed, the FTC actively monitors the company until 2041, and any future privacy violations could trigger new legal action.
