In 2025, one of the biggest privacy lawsuits in tech concluded when Flo Health, the maker of the popular period-tracking app, reached a multi-billion-dollar settlement over allegations it shared sensitive user data with Meta (formerly Facebook) and Google without consent. While the amount of the settlement was undisclosed, the case serves as a stark reminder of the importance of data privacy in a world increasingly driven by digital health solutions.
This article delves into seven critical lessons entrepreneurs and startups can learn from this case. With insights, stats, and tools, we also introduce ways to build compliant and trustworthy products while staying ahead in the competitive startup ecosystem.
Insights from the Flo Health Lawsuit
1. Transparency and Compliance Are Non-Negotiable
The lawsuit alleged that Flo Health shared users’ highly personal health data, like menstrual cycles and pregnancy status, with Meta and Google through embedded software development kits (SDKs). This action, reportedly taken without the explicit consent of users, directly contravened user trust and data privacy laws.
Actionable Lesson:
- Audit your tech partners: If you use third-party SDKs, ensure they meet compliance standards.
- Be clear in your privacy policies: Use plain language to explain how and why data is collected and shared.
2. Litigation Risk Can Be High Despite Lack of Evidence
The case faltered because plaintiffs couldn’t provide direct evidence that data collected via Flo’s app was misused by Meta. This lack of evidence led the judge to describe the claim as “insurmountable.” However, the legal costs and reputational damage were immense.
Actionable Lesson:
- Even if allegations seem weak, lawsuits can cost millions and harm your reputation. Prevention is cheaper than resolution.
- Proactively adopt privacy-first development practices to protect your business from potential lawsuits.
3. Build Consumer Trust Through Proactive Updates
This wasn’t Flo Health’s first encounter with data privacy regulators. In 2021, the Federal Trade Commission (FTC) already tackled the app for similar allegations. Flo agreed to revamp its privacy infrastructure, demonstrating that compliance grows in layers.
Actionable Lesson:
- Regularly update your privacy strategy: Laws change, and privacy expectations evolve.
- Use tools like the AI Startup Lawyer, which analyzes your agreements and ensures compliance with privacy and legal standards. Startups can avoid legal missteps by acting early. Learn more about AI Startup Lawyer.
4. Femtech and Healthtech Are Under a Regulatory Microscope
Flo Health’s rise as Europe’s first femtech unicorn expanded its influence, but also attracted more scrutiny. Health apps, especially those focused on women’s health, are a favorite target for regulators because of the sensitivity of the data they collect.
Actionable Lesson:
- Understand all regulatory layers in your market (e.g., GDPR, HIPAA).
- Start early: Use tools like the F/MS AI Grant Finder to identify EU funding programs that can help you afford data privacy upgrades. This tool even drafts grant applications tailored to your startup. Find and apply for your EU grant here.
5. Always Vet Your Data Use Agreements
Data-sharing partnerships come with risks. In Flo’s case, the use of Meta’s SDKs to analyze marketing data exposed them to liability claims.
Actionable Lesson:
- Stay cautious when signing agreements with accelerators, investors, or third-party vendors.
- Upload contracts like your CLA agreements to the AI Startup Lawyer and receive clear insights on potentially harmful clauses.
6. Trust and Reputation Are Priceless
Consumer trust takes years to build and seconds to lose. Flo’s FTC settlement and class-action lawsuit have likely eroded its reputation, though its unicorn valuation remains intact.
Actionable Lesson:
- Prioritize user education: Transparency isn't just regulatory, it’s a brand asset.
- Use tools like PlayPal, the personalized AI co-founder, to refine messaging and consumer engagement strategies. Explore how PlayPal works on this page.
7. Adapt to an Evolving Privacy Landscape
Since Flo’s lawsuit, global privacy laws are becoming stricter. From Europe’s GDPR to California’s new California Privacy Rights Act, the pressure is on for companies to manage user data responsibly.
Actionable Lesson:
- Adopt flexible, scalable privacy tools that adapt as regulations change. Consider using resources like the Fe/male Switch Startup Simulator to learn practical strategies for early-stage startups.
How to Protect Your Startup from Privacy Lawsuits
Here’s a step-by-step guide for startups to stay ahead in data privacy and legal compliance:
Step 1: Identify Risks Early

Avoid These Common Mistakes
Here are the top three privacy-related errors startups make:
- Not reading third-party agreements: Always know what permissions your SDKs and APIs operate under.
- Skipping legal reviews: CLAs or shareholder agreements can sneak in risky language. Use AI tools to stay informed.
- Delaying privacy features until scaling: Compliance should start at the ideation stage, not post-launch.
