Security & Privacy
0/25
Flo presents a mixed security and privacy profile. Strengths include comprehensive, specific privacy policy language, ISO 27001/27701 certifications, strong user controls (deletion rights, Anonymous Mode), clear data minimization principles, and explicit commitment to not selling data. However, critical concerns dominate the assessment: (1) FTC enforcement action (2021) for sharing period tracking data with Facebook/Google without adequate consent—a major historical violation that contradicts the claim of 'no regulatory actions' in the summary; (2) vague language around additional unspecified third-party data enhancement partners; (3) lack of documented encryption at rest, HIPAA compliance, SOC 2 certification, or MFA despite handling sensitive reproductive health data; (4) incomplete public documentation of account deletion/data export procedures. For a medical product classified as such (even if regulated as wellness), the FTC enforcement action is a significant negative factor that cannot be overlooked. The current policy appears improved, but the track record score reflects the severity of the past violation. The security infrastructure is adequate but not comprehensive for sensitive health data.
Strengths
- Comprehensive, specific privacy policy (security_evidence_privacy_policy_clarity): named third parties, explicit data categories, clear user rights, no data selling commitment
- ISO/IEC 27001 and ISO/IEC 27701 certifications (security_evidence_security_certifications): industry-standard information security and privacy certifications
- Strong user controls (security_evidence_privacy_policy_details): explicit deletion rights, Anonymous Mode, data export capability (iOS Premium), 90-day full purge timeline
- Data minimization articulated (security_evidence_privacy_policy_details): stated principle of processing data only for authorized purposes
- Health data appropriately protected from marketing partners (security_evidence_privacy_policy_details): AppsFlyer/Firebase receive marketing data but NOT health data
- Encryption in transit documented (security_evidence_app_store_permissions): Google Play listing confirms transit encryption
Concerns
- FTC enforcement action (2021) for unauthorized sharing of period/sexual health data with Facebook/Google (regulatory_info links): major historical regulatory violation that directly contradicts stated 'no regulatory actions' claim. This is not a minor issue but a fundamental privacy breach involving sensitive reproductive data.
- Vague third-party sharing language (security_evidence_language_specificity): 'additional unspecified partners' and 'others' in AppsFlyer network mentioned without specificity; unclear who accesses data for enhancement/personalization
- No documented encryption at rest (security_evidence_security_certifications): only transit encryption confirmed; rest-of-data encryption not explicitly stated
- No HIPAA compliance documentation (security_evidence_security_certifications): despite handling sensitive health data from US users, no HIPAA compliance statement found
- No MFA or SOC 2 documentation (security_evidence_security_certifications): expected security infrastructure details not publicly documented
- Account deletion/data export procedures not fully detailed publicly (security_evidence_faq_help_center): procedures referenced as existing but specific steps not confirmed in available sources
- Track record summary contradicts provided evidence (security_evidence_track_record vs. regulatory_info): FTC action and Meta lawsuit clearly documented in provided URLs but summary claims 'no regulatory actions'—indicates either data quality issue or documentation inconsistency

Accuracy
0/25
Flo presents a complex regulatory picture. While classified as 'Medical' per the evaluation framework, Flo explicitly disclaims medical device status and is not FDA-cleared, CE-marked, or registered as a medical device. This is a critical issue for medical product classification: the regulatory_status sub-criterion scores 0/4 because no appropriate medical clearance exists. However, Flo's clinical validation is strong with 22+ peer-reviewed studies in high-quality journals, large sample sizes (22+ million app users as research population), and study designs including RCTs. Medical partnerships are substantive with named academics from tier-1 institutions serving on scientific advisory board and collaborating on published research. Independent reviews are sparsely documented in provided sources (missing_expected, 2/4). Transparency about limitations is excellent with prominent disclaimers in Terms of Service and App Store listings. The central tension is that Flo makes clinical claims (fertility predictions, symptom tracking) backed by legitimate peer-reviewed research, yet explicitly positions itself as a wellness/tracking tool rather than a medical device. This may indicate either: (1) regulatory strategy to avoid medical device classification, or (2) genuine positioning as an evidence-supported wellness tool. For SAFE Accuracy scoring as a Medical product, the lack of regulatory clearance is a significant gap (0/4), but strong clinical research (7/8), institutional partnerships (5/6), and transparency (3/3) partially offset this. Missing independent clinical reviews (2/4) adds to concern. Raw score before weighting: (0+7+5+2+3)/25 = 17/25. However, the regulatory status failure significantly undermines the medical classification.
Strengths
- Strong clinical validation: 22+ peer-reviewed studies published in high-impact journals (Nature, BMJ Public Health, JMIR) with large sample sizes and diverse study designs (RCTs, longitudinal, cross-sectional) per Science & Research page
- Substantive medical partnerships: Named academics from tier-1 institutions (Yale, Johns Hopkins, University of Virginia, Texas Christian University, University College London) serve on scientific advisory board per About/Experts page
- Comprehensive research infrastructure: 140+ medical experts, 20+ scientists dedicated to female health research with 22+ million research participants per Science & Research page
- Excellent transparency about limitations: Prominent disclaimers in bold/caps in Terms of Service explicitly stating app is not a medical device, not for diagnosis/treatment, not for contraception, with directive to consult healthcare providers
- Positive user reports on accuracy: App Store and Google Play reviews cite accuracy for ovulation tracking and fertility awareness per accuracy_evidence_app_store_reviews
- Published accuracy metrics: Symptom checker study documented 81.8-100% sensitivity and 75-84.6% specificity for specific conditions (endometriosis, PCOS, fibroids) per Science & Research page
Concerns
- No FDA clearance or medical device registration: Per Terms of Service and regulatory_info, Flo explicitly disclaims medical device status and has no FDA 510(k) clearance, CE mark, or equivalent regulatory approval despite clinical claims and Medical classification. This is a critical regulatory gap for a product classified as 'Medical'
- Regulatory/classification mismatch: Product is clinically validated and research-backed yet explicitly positioned as wellness/Health & Fitness app rather than medical device. Classification as 'Medical' may be inappropriate given explicit regulatory disclaimers
- All research is company-funded: Per accuracy_evidence_research_papers_notes, all studies are conducted by Flo's own research team using Flo app user data. No truly independent third-party clinical validation studies found in provided sources
- Limited independent review evidence: No published independent clinical reviews, third-party accuracy validations, or non-affiliated researcher evaluations found in provided sources. Trustpilot and app store reviews mentioned but with limited detail on accuracy-specific feedback
- Privacy enforcement actions: Multiple FTC regulatory actions cited in source documents regarding Meta data sharing (referenced but not detailed: FTC Decision and Order, privacy lawsuit settlements). While not directly about accuracy, raises questions about data handling practices that inform product trustworthiness
- Fertility/contraception predictions not validated as contraceptive method: Terms of Service explicitly prohibits use as birth control or contraception, and app not approved for this purpose. Marketing may overstate predictive capability given frequent real-world cycle irregularities
- Sample selection bias: All research conducted using Flo app users (self-selected population with app access, likely different demographic from general population) per research_papers_notes
What We Couldn't Find
- FDA 510(k) clearance status or explanation why not pursued - expected given Medical classification and clinical claims CE mark or equivalent EU medical device registration - expected for international product available in 23 languages Independent third-party clinical validation studies - expected for Medical product claiming clinical features (no non-affiliated researcher evaluations found) Published independent reviews of Flo's accuracy from medical journals or independent research organizations - expected for Medical product Specific fertility prediction accuracy rate validated by external parties - referenced in marketing but not independently verified Details on Trustpilot reviews and overall rating - link provided but content details not extracted Comparison studies vs other fertility tracking methods or gold standards - no head-to-head validation studies found Regulatory approval history and decisions by FDA or other regulatory bodies - no documentation of regulatory submissions or decisions Documentation of how accuracy claims are substantiated for marketing purposes - no methodology documentation found Clinical practice guidelines or professional society endorsements - only DRG survey of OB/GYNs mentioned, not formal endorsements
FND
Foundation
0/25
Flo Health demonstrates STRONG Foundation across all five sub-criteria. The company has established credible leadership with deep expertise in women's health, clinical research, and medical science. The mission is highly specific and actionable, centered on improving women's health globally with particular focus on equity through the Pass It On Project. The Scientific Advisory Board includes internationally recognized researchers from top-tier institutions (Yale, Johns Hopkins, University of Virginia, UCL) with relevant expertise in women's health, psychiatry, neuroscience, and digital medicine. Thought leadership is evident through prolific peer-reviewed research output, active science team publication record, and extensive health education content. Marketing messaging aligns well with the stated mission, emphasizing user autonomy, body knowledge, and inclusive healthcare rather than exploitative fear-based appeals. The company demonstrates commitment to equity through multilingual support (23+ languages), accessible pricing (freemium model with Premium subscription), and the Pass It On Project extending free premium access to underserved communities. The regulatory history shows a significant privacy violation settlement with Meta/FTC in 2021, but this relates to Security/Privacy (not Foundation) and the company has since implemented corrective measures with ISO certifications and stronger data practices. Overall, Foundation dimension reflects a well-established company with credible leadership, clear mission, strong expert partnerships, active thought leadership, and marketing practices that respect users.
Strengths
- Leadership team demonstrates strong expertise in women's health, clinical research, and medical science with 100+ doctors and scientists, including named PhD-level directors across medical accuracy and science functions (from foundation_evidence_leadership_team)
- Scientific Advisory Board includes internationally recognized academics from top institutions: Yale, Johns Hopkins, University of Virginia, University College London, Texas Christian University (from foundation_evidence_advisory_board)
- Mission is specific and actionable with concrete equity commitment through Pass It On Project targeting 1 billion women in underserved communities (from foundation_evidence_mission_vision)
- Strong thought leadership demonstrated through peer-reviewed publications in Nature, BMJ Public Health, and other top-tier journals with research involving 22+ million participants (from foundation_evidence_blog_thought_leadership)
- Marketing messaging emphasizes user autonomy ('Know your body. Own your health') and inclusivity rather than fear-based appeals (from foundation_evidence_marketing_alignment)
- Demonstrated commitment to accessibility through 23+ language support and Anonymous Mode feature (from equity_evidence_language_options and foundation_evidence_social_media)
- Inclusive product design addressing diverse health needs including PCOS, perimenopause, pregnancy, and dedicated LGBTQ+ support section (from foundation_evidence_product_design_diversity and equity_evidence_lgbtq_cultural)
Concerns
- No founder names or founding date provided in available sources; limited company history details despite requesting that information (from foundation_evidence_company_history showing gap)
- While 100+ doctors and scientists claimed, only 8-10 specific named leaders provided; verification of claimed team size not independently confirmable from available sources
- No documentation of how advisory board members are engaged or their involvement frequency; appears to be research collaboration rather than active governance advisory role
- Limited documentation of diversity within leadership team (only 3-4 names appear to indicate gender diversity among named leaders; no racial/ethnic diversity metrics provided)
- Social media presence noted (TikTok @flohealthapp) but content quality and engagement details not available for assessment
- No explicit statement regarding team diversity metrics, DEI commitments, or workforce composition beyond the Glassdoor link reference (not analyzed in provided sources)
What We Couldn't Find
- Founder names and founding date/year not provided in available sources despite checking foundation_evidence_company_history Diversity metrics for leadership team (race, ethnicity, gender representation) not documented in available sources Advisory board engagement frequency and governance role clarity not specified (research collaboration vs. advisory governance) Specific social media content quality assessment not possible; only TikTok handle mentioned without content details Board of Directors composition not documented in available sources Details on how diversity, equity, and inclusion goals are operationalized beyond Pass It On Project
EQT
Equity
0/25
Flo demonstrates strong accessibility infrastructure (23 languages, free usable tier, accessibility statement) and emerging inclusive positioning (LGBTQ+ section, Pass It On Project for underserved communities), but critical equity documentation gaps significantly limit the overall score. The product shows awareness of serving diverse populations globally but lacks evidence of intentional inclusive design processes, diversity representation in marketing, robust individual affordability mechanisms (sliding scale, Medicaid), and documented partnerships with community health organizations. For a Medical classification product with 420+ million users claiming global reach to underserved populations, the absence of documented diverse representation, community partnerships, and individual financial assistance mechanisms is concerning. The free tier provides baseline accessibility, but premium features create potential barriers for low-income users. Pass It On Project addresses global equity for underserved communities but doesn't address individual user affordability within Flo's primary user base. Language support is excellent (23 languages) but technical accessibility standards (WCAG level, screen reader compatibility) are not documented. Medical products serving women's health should demonstrate intentional design inclusion; Flo shows intent through LGBTQ+ section and global mission but lacks rigorous evidence of inclusive implementation.
Strengths
- Exceptional multilingual support (23 languages on website, 6 in Help Center) enabling access for non-English speakers globally - foundation_evidence_mission_vision and equity_evidence_language_options
- Free tier available indefinitely with useful core features (period tracking, ovulation prediction, symptom logging, calendar, Secret Chats, Anonymous Mode) removing cost barrier to basic functionality - equity_evidence_pricing_cost
- FSA/HSA eligible status providing tax-advantaged access for users with these accounts - equity_evidence_pricing_cost
- Pass It On Project explicitly addressing health equity by providing free Premium memberships to underserved populations globally, targeting 1 billion women in resource-limited settings - foundation_evidence_mission_vision
- Dedicated LGBTQ+ section on website indicating intentional inclusivity for sexual/gender minorities - equity_evidence_lgbtq_cultural
- Accessibility Statement published (flo.health/accessibility-statement-flo) and device accessibility features recognized in data handling - equity_evidence_accessibility_wcag
- Product design supports diverse menstrual health situations (irregular periods/PCOS, perimenopause, pregnancy, postpartum, sexual health) with customizable symptom tracking - equity_evidence_product_design_diversity
- User testimonials reflect some diversity (PCOS, irregular periods, fertility challenges) suggesting product utility across health situations - accuracy_evidence_app_store_reviews
Concerns
- Zero evidence of visual/imagery diversity in marketing materials, website, or testimonials despite serving women globally across racial, body size, age, and disability groups - equity_evidence_imagery_diversity explicitly documents this gap
- No documented sliding scale, financial assistance, or low-income programs for individual users; affordability based solely on free tier or ability to pay - equity_evidence_sliding_scale states explicitly 'does not currently offer a sliding scale or financial assistance program'
- No Medicaid acceptance documented, potentially excluding low-income insured populations - equity_evidence_pricing_cost
- No student discounts or special pricing programs identified - equity_evidence_sliding_scale
- Community advocacy limited to Pass It On Project; no documented partnerships with specific community health organizations, local health initiatives, or grassroots women's health programs - equity_evidence_community_programs
- No evidence of inclusive design processes, user testing with diverse populations, or accessibility testing (WCAG compliance level, screen reader compatibility not documented) - equity_evidence_product_design_diversity and equity_evidence_accessibility_wcag
- LGBTQ+ section exists but specific content inclusivity details, language sensitivity, and transgender health feature specificity not documented - equity_evidence_lgbtq_cultural
- Testimonial diversity is anecdotal rather than evidence of intentional inclusive design research or representation strategy - accuracy_evidence_app_store_reviews
- Global scale (420+ million users) contradicts limited evidence of intentional equity-focused product design or community partnership strategy
What We Couldn't Find
- Visual representation diversity analysis: no evidence of racial diversity, body size diversity, age diversity, disability representation, or gender identity representation in marketing imagery, website content, or testimonials (expected for global women's health product) - should find at equity_evidence_imagery_diversity and marketing_materials Individual affordability mechanisms: no sliding scale, financial assistance programs, scholarships, or need-based access programs documented for individual users (expected for Medical classification product claiming global equity commitment) - should find at equity_evidence_sliding_scale and pricing_page Insurance coverage: no Medicaid, Medicaid managed care, or other insurance partnerships documented (expected for Medical product) - should find at equity_evidence_pricing_cost and pricing_page Community health partnerships: no specific named partnerships with community health organizations, public health agencies, or grassroots women's health initiatives documented (expected for product with equity mission) - should find at equity_evidence_community_programs Inclusive design documentation: no evidence of user testing with diverse body types, disabled users, transgender users, or other marginalized populations; no WCAG compliance level or accessibility testing results (expected for accessible digital product) - should find at equity_evidence_product_design_diversity and equity_evidence_accessibility_wcag LGBTQ+ content specificity: dedicated LGBTQ+ section exists but no details about transgender health features, inclusive language, or content diversity (expected given navigation link exists) - should find at equity_evidence_lgbtq_cultural Marketing diversity: marketing materials not provided for analysis of messaging inclusivity, stereotype avoidance, or representation strategy - should find at marketing_materials Detailed WCAG compliance level: Accessibility Statement exists but WCAG level (A/AA/AAA) not documented in available sources
