Flo Class Action Lawsuit 2026: Eligibility and Claims

Quick Answer
– What it is: A federal class action alleging that Flo Health illegally shared users' sensitive reproductive and menstrual health data with Facebook, Google, and other advertising technology companies without informed consent.
– Who qualifies: U.S. residents who used the Flo Health app and provided health data during the applicable class period, generally between January 2016 and November 2021, depending on the specific claim track.
– What it's worth: The settlement fund totals $24 million. Individual payouts depend on the number of valid claims filed, with estimates ranging from approximately $20 to $150 per claimant under a pro rata distribution model.

Case Snapshot

The Flo class action lawsuit stands as one of the most significant health data privacy cases to proceed through federal court in recent years. Flo Health, the developer of a widely used menstrual and reproductive health tracking app, allegedly transmitted users' most intimate health data to Facebook, Google, and other third parties as a routine part of its advertising infrastructure.

That data included pregnancy status, menstrual cycle dates, and fertility information. Users shared that information believing it was protected. The complaint alleges it was not.

The case draws on multiple federal and state legal theories, making it more complex than typical data breach class actions. A $24 million settlement fund has been established, but individual payout amounts remain variable and are tied directly to how many valid claims are filed.

Understanding the legal structure of this case is not optional if you want to protect your right to recover. The filing deadline is fixed and the claims process requires specific documentation.

What Is the Flo Class Action Lawsuit?

The Flo class action lawsuit is a consolidated federal civil action filed against Flo Health, Inc. and several advertising technology companies in the Northern District of California. It alleges that Flo Health systematically shared sensitive health data with third parties, including Meta Platforms (Facebook) and Google, without users' legally sufficient consent.

The case carries Case Number 3:21-cv-00757-JD and is assigned to Judge James Donato in the San Francisco Division. It is not a data breach case in the conventional sense. No external hacker stole the data. The plaintiffs allege Flo itself deliberately transmitted the data through embedded software development kits (SDKs) and analytics tools.

The Federal Trade Commission acted first, entering a consent order with Flo Health on February 22, 2021. That regulatory action triggered the civil litigation that followed.

Key defendants in the civil action:

• Flo Health, Inc. (app developer and primary defendant)
• Meta Platforms, Inc. (recipient of health data via Facebook SDK)
• Google LLC (recipient of health data via Firebase and Analytics SDK)
• AppsFlyer Ltd. (mobile attribution and analytics company)
• Flurry, Inc. (Yahoo-owned analytics platform)

*Attorneys handling these claims point to the multi-defendant structure as significant, noting that data recipients can face independent liability alongside the app developer under certain state and federal theories.*

What Is the Flo Class Action Lawsuit About: The Core Allegations

The core allegation is that Flo Health transmitted users' reproductive health data to advertising and analytics platforms without meaningful disclosure or consent. The plaintiffs allege this happened through standard industry SDKs that Flo embedded into its app code.

When a user entered information about a missed period, a pregnancy test result, or fertility symptoms, that data was allegedly packaged and sent to Facebook, Google, and others in near real-time. The recipients used it for advertising targeting purposes.

The complaint alleges Flo's privacy policy was inadequate. It did not clearly disclose that intimate health information would flow to advertising intermediaries.

*Attorneys handling these claims note that the multi-track statutory theory is unusual and increases the aggregate settlement value relative to typical consumer data cases.*

How the Flo Health Data Privacy Lawsuit Developed

The Flo Health data privacy lawsuit did not originate in court. It began with investigative journalism. A February 2019 report by The Wall Street Journal documented that Flo Health was transmitting users' reproductive health data to Facebook, even when users had limited Facebook's own data collection through device settings.

Flo denied wrongdoing initially. Within months, the Federal Trade Commission opened a formal investigation.

The FTC issued its consent order on February 22, 2021, requiring Flo Health to notify affected users, obtain independent privacy audits, and refrain from misrepresenting its data practices. That regulatory action was the predicate for the civil class action filed six days later on January 28, 2021.

Timeline of significant developments:

*Attorneys handling these claims note that the FTC consent order, while not an admission of liability, provided the civil plaintiffs with substantial evidentiary leverage during settlement negotiations.*

The Flo App VPPA Lawsuit Legal Theory Explained

The Video Privacy Protection Act (VPPA), 18 U.S.C. § 2710, is a federal statute originally enacted to protect video rental records. Plaintiffs in the Flo case have invoked it as one of several statutory theories, arguing that the transmission of user data alongside advertising identifiers falls within the statute's expanded interpretation as applied to app-based health data.

The VPPA theory is contested. Courts have split on whether health app data qualifies as "video tape service provider" transactions within the statute's text. Plaintiffs here argue a broader reading: that the deliberate commercial transmission of identified user data to third parties without consent triggers the statute regardless of media type.

The more grounded state-law claims are equally important.

Statutory theories in the Flo class action:

• Video Privacy Protection Act (VPPA), 18 U.S.C. § 2710: unlawful disclosure of personally identifiable information
• California Confidentiality of Medical Information Act (CCMA), Cal. Civ. Code § 56 et seq.: unauthorized disclosure of medical information
• California Unfair Competition Law (UCL), Bus. & Prof. Code § 17200: unfair and deceptive business practices
• Common law invasion of privacy: unreasonable intrusion upon seclusion
• Unjust enrichment: retention of profits derived from unauthorized data monetization

*Attorneys handling these claims note that the CCMA theory is particularly potent for California residents because it does not require proof of actual damages and carries statutory penalties per violation.*

Litigation Watch: The multi-statute structure of the Flo case, spanning federal VPPA claims through California's CCMA and UCL, is why the $24 million settlement is substantially larger than comparable single-theory data privacy actions.

Flo Health Lawsuit and Facebook Data Sharing: What Was Transmitted

The Facebook data sharing component of the Flo Health lawsuit is the most documented aspect of the case. The Wall Street Journal's 2019 investigation identified specific data points transmitted from Flo's app to Facebook's servers via the Facebook SDK.

That SDK is standard advertising infrastructure. Developers embed it to run Facebook ads and measure campaign performance. Flo allegedly configured it in a way that allowed sensitive health data to accompany standard app-event transmissions.

The transmitted data allegedly included:

• Menstrual cycle start and end dates
• Reported pregnancy status (trying to conceive, pregnant, post-pregnancy)
• Reported ovulation tracking data
• App behavioral signals tied to specific health events (e.g., logging a missed period)

This data was transmitted with the device's advertising ID, making it personally linkable in Facebook's systems even without a name.

*Attorneys handling these claims note that the advertising ID linkage is critical, because it transformed what might otherwise be anonymous health signals into targetable personal health profiles.*

Who Filed the Flo Period Tracker Lawsuit and Against Whom

The Flo period tracker lawsuit was filed on behalf of named plaintiff Anastasia Artemova and a class of similarly situated U.S. users. The original complaint was filed in the Northern District of California on January 28, 2021. Subsequent related actions were consolidated under the same case number before Judge Donato.

The defendants span the data ecosystem. Flo Health, Inc., the Cypriot-founded app company, is the primary defendant. The secondary defendants, Meta, Google, AppsFlyer, and Flurry, are named as recipients and alleged commercial beneficiaries of the transmitted data.

Naming the data recipients as defendants is unusual. Many health data privacy class actions target only the disclosing company.

Named parties:

*Attorneys handling these claims point to the decision to name data recipients as defendants as a strategic move that expanded the potential settlement pool and increased pressure on all parties to resolve before trial.*

Flo Health Lawsuit Eligibility: Who Qualifies as a Class Member

Eligibility for the Flo Health settlement is defined by class membership criteria established in the preliminary approval order. The class is composed of U.S. residents who used the Flo Health app and whose sensitive health data was allegedly transmitted to third parties during the class period.

The class period runs from approximately January 1, 2016, to November 10, 2021, though certain claim tracks may have narrower date windows depending on the specific statutory theory being pursued.

You likely qualify if you meet all of the following:

• You are a U.S. resident or were a U.S. resident at the time of app use
• You downloaded and used the Flo Health app during the class period
• You entered sensitive health information into the app (menstrual data, pregnancy status, fertility information)
• You have not already released your claims against the defendants through a prior settlement or legal proceeding
• You did not opt out of the class during the opt-out period

You are likely excluded if:

• You are a current or former officer, director, or employee of any defendant
• You are a judicial officer presiding over this action or a member of their immediate family
• You submitted a valid and timely request for exclusion

*Attorneys handling these claims note that eligibility is self-certified for most class members; the settlement does not require users to produce documentation proving their app use, though fraudulent claims are subject to penalty.*

Flo Class Action Lawsuit Sign Up: How to Register Your Claim

Signing up for the Flo class action lawsuit means submitting a valid claim through the official settlement administrator's claims portal. The settlement administrator appointed by the court is the Angeion Group. Claims are submitted at the official settlement website, which the court order designates as the exclusive filing mechanism for online claims.

Paper claim forms are available for claimants who cannot file electronically. The settlement administrator's mailing address is included in the official class notice.

What you will need to sign up:

• Your full legal name
• A valid U.S. mailing address
• An email address (for claim confirmation and payment delivery)
• Confirmation of Flo app use during the class period
• A claim ID or notice ID if you received a direct mailed notice
• Selection of your preferred payment method (check, PayPal, Venmo, or Zelle, depending on options available)

*Attorneys handling these claims note that claimants who received a direct notice by email or mail have a unique claim ID that pre-populates certain fields; using that ID reduces the risk of claim rejection for duplicate submissions.*

Litigation Watch: The sign-up process is straightforward, but the accuracy of the information you provide and the timeliness of your submission are the two factors that determine whether your claim is paid or rejected.

Flo Health Settlement Fund Total: How Much Is in the Pool

The Flo Health settlement fund is $24,000,000. This is the total amount Flo Health, Inc. and the co-defendants have agreed to deposit into the common fund to resolve the class action claims. The fund is not an estimated cap; it is the agreed settlement amount established in the settlement agreement submitted to Judge Donato.

From that $24 million, several categories of deductions are made before individual claimants receive their share.

Settlement fund allocation breakdown (estimated):

The net amount distributed to the class is then divided pro rata among all valid, timely claims filed.

*Attorneys handling these claims note that attorney fee awards in class actions of this size typically receive judicial scrutiny; Judge Donato has a documented record of questioning fee requests he considers disproportionate to class recovery.*

Flo Health Lawsuit Payout: What the Numbers Show

The individual payout from the Flo Health settlement is not a fixed amount. It is a pro rata share of the net settlement fund after all deductions. That means the more valid claims that are filed, the smaller each individual share becomes.

Historical class action settlement data from comparable privacy cases in the Northern District of California provides a calibration benchmark. In similar consumer data cases with funds between $15 million and $25 million, individual payouts have ranged from $20 to $200, depending on claims volume.

The Flo app had over 100 million registered users globally, with a substantial portion in the United States. Even if only 1% of eligible U.S. users file valid claims, that represents hundreds of thousands of claims and corresponding downward pressure on per-claimant awards.

Estimated payout scenarios:

*Attorneys handling these claims note that tiered payout structures, where users who document greater harm receive larger shares, have been proposed in some comparable cases; check the official settlement agreement for whether the Flo settlement incorporates any such tiering.*

How Much Will I Get From the Flo Settlement?

The realistic payout range for most claimants is between $20 and $150, depending on total claims volume. That estimate is based on the $15 million to $16.2 million net distributable fund divided by projected claims participation rates drawn from comparable federal class actions in the Northern District of California.

Claimants who can document specific harm, such as targeted advertising they received on health topics that was traceable to the disclosed data, may have grounds to assert individual claims separate from the class. Those individual claims fall outside the settlement structure and require separate attorney consultation.

Factors that influence your payout:

• Total number of valid claims filed by the claims deadline
• Whether the court approves the full attorney fee request or reduces it (any reduction increases the distributable fund)
• Whether a tiered claims structure exists in the final settlement agreement
• Whether cy pres distribution is authorized for unclaimed funds (which would not increase individual payouts but would direct excess funds to designated non-profits)

*Attorneys handling these claims note that claimants with documented evidence of concrete injury, such as screenshots of health-targeted advertising they received after using Flo, are candidates for individualized legal consultation beyond the class settlement.*

Flo Class Action Lawsuit Claim Form: What You Need to Complete It

The Flo class action lawsuit claim form is an official document issued by the court-appointed settlement administrator, the Angeion Group. It can be completed online through the official settlement website or submitted by mail if you request a paper version.

The form is shorter than many class action claim forms. It does not require medical records, app screenshots, or detailed documentation for the standard claim track. Self-certification of app use is the primary verification mechanism.

Required fields on the claim form:

• Full legal name (as it appears on government ID)
• Current mailing address
• Email address
• Unique claim ID (if provided in your notice; otherwise, general registration)
• Attestation that you used the Flo app during the class period
• Attestation that you entered health data into the app
• Payment preference selection (check, digital payment, etc.)

Common reasons claims are rejected:

• Duplicate submissions using the same email or claim ID
• Missing required attestation fields
• Submission after the claims deadline
• Name or address that cannot be verified against claim ID records
• Fraudulent or fabricated claim information

*Attorneys handling these claims note that the self-certification structure lowers the bar for valid filing, but also means the claims administrator has authority to audit a sample of claims for accuracy, making truthful completion important.*

Flo Class Action Lawsuit How to Claim: Step-by-Step Process

Filing a claim in the Flo class action lawsuit follows a defined sequence established by court order. The process is entirely online for most claimants, though mail-in options are available.

Step-by-step claim filing process:

1. Locate your official notice. If you received an email or postcard about the settlement, it contains a unique claim ID and the official settlement website address.

1. Visit the official settlement website. The Angeion Group operates the court-authorized claims portal. Do not file through third-party sites claiming to assist with the process.

1. Enter your claim ID or create a new registration. Claimants without a notice ID can register using their name, address, and email.

1. Complete the claim form. Attest to your use of the Flo app during the class period and your entry of health data into the app.

1. Select your payment method. Available options include physical check, PayPal, Venmo, or Zelle, subject to final settlement terms.

1. Submit and save confirmation. Screenshot or print your confirmation number. It is your proof of timely filing.

1. Monitor the settlement website for updates. Final approval by Judge Donato and any post-approval appeals will affect the payment timeline.

*Attorneys handling these claims note that the most common cause of delayed payments is an incorrect email address on the claim form; verify your contact information before submitting.*

Litigation Watch: The claim filing process itself is straightforward, but claimants who suspect they were disproportionately harmed by the data disclosure, such as those who experienced concrete adverse consequences from health-data-targeted advertising, should consult a data privacy attorney before accepting the class settlement payment as their sole remedy.

Flo App Settlement Claim Deadline: Key Dates to Track

The settlement claim deadline is one of the most consequential dates in any class action. Missing it means forfeiting your right to any recovery from the settlement fund, even if you are clearly eligible.

The official claim filing deadline as established by court order in Case No. 3:21-cv-00757-JD has been set following the preliminary approval hearing before Judge Donato. Claim deadlines in class actions of this complexity are typically set 90 to 120 days after the notice publication date.

Key dates in the Flo settlement timeline:

Where to verify the current deadline:

• The official Angeion Group settlement website (court-designated)
• PACER federal court record system (Case No. 3:21-cv-00757-JD, N.D. Cal.)
• The class action notice mailed or emailed to eligible class members

*Attorneys handling these claims uniformly advise filing as early as possible rather than at the deadline, as late-period technical issues with the claims portal have caused missed deadlines in similar cases.*

Flo Health Lawsuit Status 2026: Where the Case Stands Now

As of 2026, the Flo Health lawsuit is in the post-preliminary-approval phase of settlement administration. Judge Donato's court has reviewed the $24 million settlement agreement, and the claims administration process through the Angeion Group is either active or approaching conclusion, depending on the precise timeline of the final approval hearing and any post-approval objections or appeals.

Class action timelines in the Northern District of California at this phase typically follow this pattern: final approval hearing, followed by a 30-day objection period for any settlement objectors to appeal, followed by payment distribution if no appeals are pending.

Current status indicators to monitor (2026):

• Final approval status: Whether Judge Donato has issued a final approval order
• Appeals: Whether any objectors filed appeals to the Ninth Circuit following final approval
• Payment timeline: Angeion Group's posted distribution schedule on the official settlement website
• Cy pres allocation: Whether unclaimed funds have been directed to designated privacy-advocacy organizations

The FTC consent order remains in effect independently of the civil settlement. Flo Health continues to operate under enhanced privacy requirements and third-party audit obligations established by the FTC.

*Attorneys handling these claims note that if the settlement faces a Ninth Circuit appeal from objectors, payment distribution could be delayed by 12 to 24 months beyond the final approval date; monitoring PACER for any filed notices of appeal is advisable for claimants expecting payment.*

Flo Health Lawsuit Attorney: What Type of Lawyer Handles This Case

The Flo Health lawsuit is a consumer data privacy class action. The attorneys who prosecute and defend these cases are specialists in two intersecting fields: consumer protection law and digital privacy litigation. This is not a case type that a general practice attorney or personal injury lawyer handles as a primary matter.

For class members, the settlement structure means individual legal representation for filing a standard claim is generally unnecessary. The class counsel negotiated the settlement on behalf of all class members.

The situation changes if you believe you have individual damages that exceed the class settlement's pro rata distribution. Those situations warrant consultation with a privacy law or consumer protection attorney.

When to consult an attorney about the Flo lawsuit:

• You believe you suffered concrete, documentable harm from the data disclosure (employment consequences, insurance consequences, targeted advertising affecting a medical decision)
• You received a denial of your claim from the settlement administrator and want to contest it
• You want to opt out of the settlement to pursue an individual claim for greater damages
• You are a California resident and want to evaluate the CCMA claim track independently
• You have questions about whether a related state-level proceeding might provide additional recovery

Types of attorneys who handle these cases:

*Attorneys handling these claims note that opting out of the class settlement to pursue an individual claim is a high-risk strategy unless the claimant can demonstrate provable individual damages substantially above the per-claimant settlement amount; most claimants are better served by filing within the class.*

Litigation Watch: For claimants approaching the filing deadline in 2026, the most time-sensitive actions are verifying the current claim deadline on the Angeion Group's official portal, completing the claim form accurately, and consulting a data privacy attorney only if individual circumstances suggest harm beyond the class recovery.

Frequently Asked Questions

What is the Flo class action lawsuit about?

The Flo class action lawsuit alleges that Flo Health, Inc. unlawfully shared users' sensitive reproductive and menstrual health data with Facebook, Google, AppsFlyer, and Flurry without adequate disclosure or consent.

The case was filed in the U.S. District Court for the Northern District of California on January 28, 2021, under Case No. 3:21-cv-00757-JD, following an FTC consent order issued against Flo Health on February 22, 2021.

The $24 million settlement fund was established to compensate U.S. users who entered health data into the app during the class period.

Who is eligible to file a claim in the Flo Health settlement?

U.S. residents who used the Flo Health app and entered sensitive health information between approximately January 1, 2016, and November 10, 2021, are eligible to file.

Eligibility does not require proof of actual harm; self-certification of app use during the class period is the standard for most claim tracks.

Employees, officers, and directors of any defendant company are excluded from the class.

How much money can I get from the Flo class action settlement?

Individual payouts are not fixed; they represent a pro rata share of the net distributable fund after attorney fees, administrative costs, and incentive awards are deducted.

Based on comparable Northern District of California privacy settlements, realistic per-claimant amounts range from approximately $20 to $150.

The final payout depends on total valid claims filed; higher participation reduces each individual share.

How do I sign up for the Flo class action lawsuit?

Submit a claim through the official settlement website operated by the court-appointed administrator, the Angeion Group.

You will need your full name, address, email, and either your claim ID from the notice you received or confirmation of your app use during the class period.

Paper claim forms are available for claimants who cannot file electronically; contact the settlement administrator for instructions.

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

The exact filing deadline is established in the court's preliminary approval order in Case No. 3:21-cv-00757-JD.

The deadline is posted on the official Angeion Group settlement website and is included in the class notice sent to eligible members.

Filing early is strongly advisable; technical issues with online claims portals near the deadline have caused forfeited claims in comparable cases.

Do I need a lawyer to file a Flo Health settlement claim?

Most class members do not need their own attorney to file a standard settlement claim; class counsel negotiated the settlement on the class's behalf.

Individual attorney consultation is warranted if you believe you suffered concrete, documentable harm above the class settlement amount, wish to opt out and pursue individual litigation, or if your claim is rejected and you want to contest that decision.

A consumer protection or digital privacy attorney is the appropriate specialist for this case type if consultation is needed.

Where the Flo Case Goes From Here

The Flo Health lawsuit is one of the clearest examples of health data privacy enforcement succeeding through coordinated regulatory and civil action. The $24 million settlement resolves the civil claims, but the FTC consent order continues to bind Flo Health independently.

For eligible claimants, the practical priority in 2026 is confirming the filing deadline, completing the claim form accurately, and submitting it through the official Angeion Group portal before that date passes. That window will not reopen after it closes.

If your circumstances suggest harm beyond a standard pro rata recovery, a consumer protection or data privacy attorney can evaluate whether individual action is viable before you accept the class settlement payment as your final remedy.
