Maya 與 Period Calendar 2026：隱私、功能及價格比較

Maya 和 Period Calendar 都是受歡迎的免費月經追蹤應用，在發展中市場擁有大量用戶。Plackal Tech 的 Maya 擁有超過 1000 萬次下載，特別在印度、巴基斯坦、孟加拉、尼泊爾和斯里蘭卡表現強勁。Simple Design 的 Period Calendar 聲稱擁有 3 億用戶，在拉丁美洲、中東、東南亞和撒哈拉以南非洲都很受歡迎。

這兩款應用吸引希望免費、可獲得的月經追蹤的用戶。兩者均以廣告支持。兩者都提供基本的周期預測、症狀記錄和日曆視圖。對於他們的目標人群——通常是在付費健康應用不太常見的市場中的年輕用戶——“免費”的價格點至關重要。

不舒服的現實是，這兩款應用都有記錄在案的隱私問題。Maya 被發現與 Facebook 分享數據。Period Calendar 聲稱不會收集數據，但卻運行需要數據的廣告網絡。對於數以億計信任這些應用的用戶來說，隱私營銷與實踐之間的差距是顯著的。

Maya's privacy failure is documented. Privacy International's September 2019 investigation found Maya transmitting intimate data to Facebook — including diary text entries where users described symptoms, moods, and sexual activity. Users writing private health notes were unknowingly sending them to Facebook's advertising ecosystem.

Period Calendar's privacy issue is structural. The app markets "we don't collect or store your data" while running Google Ads, DoubleClick, and AdMob. Privacy International documented heavy third-party traffic to Google advertising services despite local storage claims. Advertising SDKs collect device identifiers and behavioral data by design.

Both apps are ad-supported, meaning both embed advertising SDKs that create data flows to third parties. Maya's flow to Facebook was documented directly. Period Calendar's flow through ad networks is inherent to its business model.

PinkyBloom eliminates ads entirely, so there are no ad SDKs collecting anything. No accounts means no identity linkage. Your cycle log is stored on your phone, encrypted and biometrically protected. For users across South Asia, the Middle East, and emerging markets, PinkyBloom provides the same accessibility (free, 71 languages, no account needed) without the ads.

Maya provides standard period tracking with cycle predictions, ovulation estimates, symptom logging, and a text diary. Health content is tailored to South Asian audiences. The diary feature is notable — and notably was the feature sending data to Facebook.

Period Calendar provides basic logging: period dates, predictions, symptom tracking, and a calendar view. It's simple and reliable but lacks any advanced intelligence.

Neither app offers AI, voice logging, or predictive health features. Both are manual logging tools with basic statistical predictions.

PinkyBloom transforms the experience with AI. Voice logging replaces manual text entry — safer than Maya's diary (which went to Facebook) and faster than Period Calendar's forms. AI mood forecasts predict patterns. Doctor visit reports create professional summaries. All available in 71 languages, covering every market where Maya and Period Calendar are popular.

Maya 和 Period Calendar 都是免費的，並且有廣告和應用內購買。財務成本微乎其微。隱私成本是權衡：兩者都使用廣告支持的模式，創建數據流向廣告網絡。

PinkyBloom 是免費的，沒有廣告。對於在免費應用至關重要的市場中的用戶，PinkyBloom 提供相同的價格點，並且擁有 AI 功能和沒有廣告干擾。
