Overview
Flo 和 Maya 是受歡迎的月經追蹤應用，擁有重疊的用戶基礎，特別是在南亞地區。Flo 是全球領導者，擁有 4.4 億用戶，是一個綜合健康平台，擁有 AI 聊天機器人、社區論壇和大量內容。Plackal Tech 的 Maya 雖然規模較小，但在印度、巴基斯坦、孟加拉國、尼泊爾和斯里蘭卡深耕多年，下載量超過 1000 萬。
Flo 吸引那些希望擁有功能豐富、一體化健康平台的用戶。Maya 吸引那些希望擁有簡單易用的月經追蹤器，並提供針對南亞受眾的健康提示的用戶。
不幸的真相是，這兩款應用都被發現與 Facebook 分享用戶的私密健康數據。Flo 的規模龐大；Maya 則通過詳細的日記條目和應用互動數據進行分享。對於他們合計超過 4.5 億的用戶基礎，這代表了健康應用歷史上最大的集體隱私侵犯之一。
Privacy comparison
Both Flo and Maya have documented records of sharing user health data with Facebook — making this comparison a case study in why cloud-based period trackers are fundamentally vulnerable.
Flo's record spans two federal proceedings. The FTC alleged data sharing with Google, Facebook, and analytics firms in 2021, and Flo settled with no fine and no admission. A class action settled in 2025; Flo paid $8M of a $56M total. A California jury found Meta liable for eavesdropping on Flo users' menstrual data.
Maya's violations were documented by Privacy International's landmark 2019 investigation "No Body's Business But Mine." The investigation found Maya transmitted intimate data — including diary text entries where users described symptoms, moods, and sexual activity — to Facebook's SDK. Users writing private health notes were unknowingly sending them to one of the world's largest advertising companies.
Maya is also ad-supported, meaning additional advertising SDKs collect data alongside the Facebook SDK. For Maya's South Asian user base, where digital privacy awareness varies widely, this represents an especially harmful betrayal of trust.
PinkyBloom has no Facebook SDK, no advertising SDKs, and no account. Your cycle log is stored on your phone, not in an account on our servers, and it's never sold.
Features and intelligence
Flo is the more feature-rich app: cloud-based AI chatbot, 70+ symptoms, community forums, pregnancy mode, and thousands of expert articles. It's built to be a comprehensive health platform.
Maya provides solid basic features: cycle predictions, ovulation estimates, symptom logging, a text diary, and health content tailored to South Asian audiences. It's simpler and more accessible but lacks advanced intelligence.
Neither app offers voice logging or predictive mood forecasting.
PinkyBloom supports 71 languages (including Hindi, Bengali, Tamil, Telugu, Kannada, Malayalam, Marathi, Gujarati, Urdu, and Punjabi) and delivers AI features neither app can match. Voice logging, mood forecasts, doctor visit reports, and encrypted partner sharing — available to users across South Asia and beyond.
Pricing comparison
Flo 每年收費約 49.99 美元的高級版。免費版有廣告。Maya 免費但有廣告，並提供應用內購買。兩者都通過廣告獲利——這同樣的廣告基礎設施使它們的數據分享成為可能。
成本問題實際上是關於你所支付的金錢以外的東西。Flo 和 Maya 都證明了它們的「免費」或廣告支持層級隱藏著你的健康數據流向廣告公司的成本。
PinkyBloom 是免費的。沒有廣告。對於希望擁有尊重其隱私的月經追蹤器的南亞及全球用戶來說，PinkyBloom 是明確的選擇。
There's a better option
Flo shared data with Google and Meta. Maya shared diary entries with Facebook. Both have proven they can't be trusted with your reproductive health data. PinkyBloom never sells your data and shows no ads — 71 languages including comprehensive South Asian coverage.
