Last updated: February 2026·Maya vs Period Calendar·PinkyBloom: Free

Our verdict

Maya was caught sharing diary entries with Facebook. Period Calendar claims no data collection while running Google Ads. Both are popular free ad-supported trackers across South Asia, the Middle East, and emerging markets — and both have privacy contradictions. PinkyBloom offers AI, 71 languages, and zero ads — and never sells your data.

Overview

Maya und Period Calendar sind beide beliebte kostenlose Menstruationstracker mit einer großen Nutzerbasis in Entwicklungsmärkten. Maya von Plackal Tech hat über 10 Millionen Downloads und ist besonders stark in Indien, Pakistan, Bangladesch, Nepal und Sri Lanka. Period Calendar von Simple Design behauptet, 300 Millionen Nutzer zu haben und ist in Lateinamerika, dem Nahen Osten, Südostasien und Subsahara-Afrika beliebt.

Beide Apps sprechen Nutzer an, die eine kostenlose, zugängliche Menstruationstrackung wünschen. Beide sind werbefinanziert. Beide bieten grundlegende Zyklusvorhersagen, Symptomprotokollierung und Kalenderansichten. Für ihre Zielgruppen – oft jüngere Nutzer in Märkten, in denen kostenpflichtige Gesundheits-Apps weniger verbreitet sind – ist der Preis von "kostenlos" entscheidend.

Die unangenehme Realität ist, dass beide Apps dokumentierte Datenschutzprobleme haben. Maya wurde dabei erwischt, Daten mit Facebook zu teilen. Period Calendar behauptet, keine Daten zu sammeln, während Werbenetzwerke betrieben werden, die dies erfordern. Für Hunderte Millionen Nutzer, die diesen Apps intime Gesundheitsdaten anvertrauen, ist die Kluft zwischen Datenschutzmarketing und -praxis erheblich.

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

Sowohl Maya als auch Period Calendar sind kostenlos mit Werbung und In-App-Käufen. Die finanziellen Kosten sind minimal. Die Datenschutzkosten sind der Kompromiss: Beide verwenden werbefinanzierte Modelle, die Datenströme zu Werbenetzwerken erzeugen.

PinkyBloom ist kostenlos ohne Werbung. Für Nutzer in Märkten, in denen kostenlose Apps unerlässlich sind, bietet PinkyBloom den gleichen Preis mit KI-Funktionen und keinen Werbeunterbrechungen.

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.
