Overview
Maya en Period Calendar zijn beide populaire gratis menstruatietrackers met grote gebruikersbasissen in ontwikkelingsmarkten. Maya van Plackal Tech heeft meer dan 10 miljoen downloads en is bijzonder sterk in India, Pakistan, Bangladesh, Nepal en Sri Lanka. Period Calendar van Simple Design beweert 300 miljoen gebruikers te hebben en is populair in Latijns-Amerika, het Midden-Oosten, Zuidoost-Azië en Sub-Sahara Afrika.
Beide apps spreken gebruikers aan die gratis, toegankelijke menstruatietracking willen. Beide zijn advertentie-ondersteund. Beide bieden basiscyclusvoorspellingen, symptoomregistratie en kalenderweergaven. Voor hun doelgroepen — vaak jongere gebruikers in markten waar betaalde gezondheidsapps minder gebruikelijk zijn — is het "gratis" prijsniveau essentieel.
De ongemakkelijke realiteit is dat beide apps gedocumenteerde privacyproblemen hebben. Maya werd betrapt op het delen van gegevens met Facebook. Period Calendar beweert geen gegevens te verzamelen terwijl het advertentienetwerken draait die dat vereisen. Voor honderden miljoenen gebruikers die deze apps vertrouwen met intieme gezondheidsgegevens, is de kloof tussen privacymarketing en praktijk aanzienlijk.
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
Zowel Maya als Period Calendar zijn gratis met advertenties en in-app aankopen. De financiële kosten zijn minimaal. De privacykosten zijn de afweging: beide gebruiken advertentie-ondersteunde modellen die gegevensstromen naar advertentienetwerken creëren.
PinkyBloom is gratis zonder advertenties. Voor gebruikers in markten waar gratis apps essentieel zijn, biedt PinkyBloom hetzelfde prijsniveau met AI-functies en geen advertentieonderbrekingen.
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.
