Maya vs Period Calendar 2026: Ochrana súkromia, funkcie a porovnanie cien
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 a Period Calendar sú obidva populárne bezplatné sledovače menštruácie s veľkými používateľskými základňami na rozvíjajúcich sa trhoch. Maya od Plackal Tech má viac ako 10 miliónov stiahnutí a je obzvlášť silná v Indii, Pakistane, Bangladéši, Nepále a na Srí Lanke. Period Calendar od Simple Design tvrdí, že má 300 miliónov používateľov a je populárny v Latinskej Amerike, na Blízkom východe, v juhovýchodnej Ázii a v subsaharskej Afrike.
Obe aplikácie oslovujú používateľov, ktorí chcú bezplatné a prístupné sledovanie menštruácie. Obe sú podporované reklamami. Obe ponúkajú základné predpovede cyklu, zaznamenávanie symptómov a kalendárové zobrazenia. Pre ich cieľové demografické skupiny — často mladších používateľov na trhoch, kde sú platené zdravotné aplikácie menej bežné — je cenový bod „bezplatne“ zásadný.
Nepohodlnou realitou je, že obe aplikácie majú zdokumentované problémy s ochranou súkromia. Maya bola prichytená pri zdieľaní údajov s Facebookom. Period Calendar tvrdí, že nezhromažďuje žiadne údaje, zatiaľ čo prevádzkuje reklamné siete, ktoré to vyžadujú. Pre stovky miliónov používateľov, ktorí dôverujú týmto aplikáciám s intímnymi zdravotnými údajmi, je rozdiel medzi marketingom ochrany súkromia a praxou významný.
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
Obe Maya a Period Calendar sú bezplatné s reklamami a nákupmi v aplikácii. Finančný náklad je minimálny. Náklad na ochranu súkromia je výmena: obe používajú modely podporované reklamami, ktoré vytvárajú prenosy údajov do reklamných sietí.
PinkyBloom je bezplatný bez reklám. Pre používateľov na trhoch, kde sú bezplatné aplikácie nevyhnutné, PinkyBloom poskytuje rovnaký cenový bod s funkciami AI a bez prerušenia reklám.
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.
