Overview
Maya og Period Calendar er begge populære gratis menstruationstrackere med store brugerbaser i udviklingsmarkeder. Maya fra Plackal Tech har over 10 millioner downloads og er særligt stærk i Indien, Pakistan, Bangladesh, Nepal og Sri Lanka. Period Calendar fra Simple Design hævder at have 300 millioner brugere og er populær i Latinamerika, Mellemøsten, Sydøstasien og Sub-Sahara Afrika.
Begge apps appellerer til brugere, der ønsker gratis, tilgængelig menstruationstracking. Begge er annonceunderstøttede. Begge tilbyder grundlæggende cyklusforudsigelser, symptomregistrering og kalenderoversigter. For deres målgrupper — ofte yngre brugere i markeder, hvor betalte sundhedsapps er mindre almindelige — er den "gratis" pris essentiel.
Den ubehagelige virkelighed er, at begge apps har dokumenterede privatlivsproblemer. Maya blev taget i at dele data med Facebook. Period Calendar hævder, at der ikke indsamles data, mens de kører annoncenetværk, der kræver det. For hundrede millioner brugere, der stoler på disse apps med intime sundhedsdata, er kløften mellem privatlivsmarkedsføring og praksis betydelig.
Privacy comparison
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.
Features and intelligence
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.
Pricing comparison
Både Maya og Period Calendar er gratis med annoncer og køb i appen. De finansielle omkostninger er minimale. Privatlivsomkostningen er afvejningen: begge bruger annonceunderstøttede modeller, der skaber datastreams til annoncenetværk.
PinkyBloom er gratis uden annoncer. For brugere i markeder, hvor gratis apps er essentielle, giver PinkyBloom den samme pris med AI-funktioner og ingen annonceafbrydelser.
There's a better option
Maya shared diary entries with Facebook. Period Calendar runs Google Ads while claiming no data collection. PinkyBloom resolves both contradictions — no ads, no ad SDKs, never sold. AI-powered health tracking in 71 languages, including Hindi, Bengali, Tamil, Telugu, Arabic, and more.
