Maya vs Period Calendar 2026: Privacy, Features & Price Compared

Maya and Period Calendar are both popular free period trackers with large user bases across developing markets. Maya by Plackal Tech has over 10 million downloads and is particularly strong in India, Pakistan, Bangladesh, Nepal, and Sri Lanka. Period Calendar by Simple Design claims 300 million users and is popular across Latin America, the Middle East, Southeast Asia, and Sub-Saharan Africa.

Both apps appeal to users who want free, accessible period tracking. Both are ad-supported. Both offer basic cycle predictions, symptom logging, and calendar views. For their target demographics — often younger users in markets where paid health apps are less common — the "free" price point is essential.

The uncomfortable reality is that both apps have documented privacy issues. Maya was caught sharing data with Facebook. Period Calendar claims no data collection while running ad networks that require it. For hundreds of millions of users who trust these apps with intimate health data, the gap between privacy marketing and practice is significant.

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 servers means no cloud data. No accounts means no identity linkage. Your data stays on your iPhone, 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) with genuine privacy.

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 on-device 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.

Both Maya and Period Calendar are free with ads and in-app purchases. The financial cost is minimal. The privacy cost is the trade-off: both use ad-supported models that create data flows to advertising networks.

PinkyBloom is free with no ads, no in-app purchases, and no privacy cost. Every feature included. For users in markets where free apps are essential, PinkyBloom provides the same price point with dramatically better privacy, AI features, and no advertising interruptions.
