Overview
FloとMayaは、特に南アジアで重複するユーザーベースを持つ人気の月経トラッカーです。Floは4億4000万人のユーザーを持つグローバルリーダーで、AIチャットボット、コミュニティフォーラム、豊富なコンテンツを備えた包括的な健康プラットフォームです。Plackal TechのMayaは規模は小さいですが、インド、パキスタン、バングラデシュ、ネパール、スリランカで深く根付いており、1000万回以上のダウンロードがあります。
Floは、機能が豊富でオールインワンの健康プラットフォームを求めるユーザーにアピールします。Mayaは、南アジアのオーディエンスに合わせた健康のヒントを提供するシンプルでアクセスしやすい月経トラッカーを求めるユーザーにアピールします。
不快な真実は、両方のアプリがユーザーの親密な健康データをFacebookと共有していることが発覚したことです。Floは大規模に行い、Mayaは詳細な日記のエントリーやアプリのインタラクションデータを通じて行いました。450万人以上のユーザーを持つ両者にとって、これは健康アプリの歴史の中で最大の集団プライバシー侵害の一つを表しています。
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はプレミアムに対して約$49.99/年を請求します。無料プランには広告があります。Mayaは広告付きで無料で、アプリ内購入を提供します。両者は広告を通じて収益を上げており — これは彼らの文書化されたデータ共有を可能にした同じ広告インフラです。
コストの問題は、本当にお金を超えて何を支払っているかに関するものです。FloとMayaは、彼らの「無料」または広告サポートプランには、あなたの健康データが広告会社に流れる隠れたコストが伴うことを証明しています。
PinkyBloomは無料です。広告なし。南アジア全体および世界中でプライバシーを尊重する月経トラッカーを求めるユーザーにとって、PinkyBloomは明確な選択肢です。
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.
