Overview
Flo ଏବଂ Period Calendar by Simple Design, ଡାଉନଲୋଡ୍ ସଂଖ୍ୟା ଦ୍ୱାରା, ସବୁଠାରୁ ପ୍ରସିଦ୍ଧ ପିରିଅଡ୍ ଟ୍ରାକର। Flo 440 ମିଲିୟନ୍ ବ୍ୟବହାରକାରୀ ଦାବି କରେ; Period Calendar 300 ମିଲିୟନ୍ ଦାବି କରେ। ସେମାନେ ମିଶି ଏକ ଅର୍ଧ ବିଲିୟନ୍ ଖାତାକୁ ପ୍ରତିନିଧିତ୍ୱ କରନ୍ତି ଯାହା ପ୍ରଜନନ ସ୍ୱାସ୍ଥ୍ୟ ତଥ୍ୟକୁ ଟ୍ରାକ୍ କରେ।
ଏହି ଆପ୍ସ ଦୃଷ୍ଟିକୋଣରେ ଅତ୍ୟନ୍ତ ଭିନ୍ନ। Flo ହେଉଛି ଏକ ସମ୍ପୂର୍ଣ୍ଣ ସ୍ୱାସ୍ଥ୍ୟ ପ୍ଲାଟଫର୍ମ ଯାହାରେ AI ଚାଟ୍ବଟ୍, ସମୁଦାୟ ଫୋରମ୍, ବିଶେଷଜ୍ଞ ବିଷୟବସ୍ତୁ, ଏବଂ ପ୍ରିମିୟମ୍ ସବ୍ସକ୍ରିପ୍ସନ୍ ଅଛି। Period Calendar ହେଉଛି ଏକ ସରଳ, କୌଣସି ଫ୍ରିଲ୍ସ ଟ୍ରାକର — ତୁମର ପିରିଅଡ୍ ଲଗ୍ କର, ପୂର୍ବାନୁମାନ ଦେଖ, ଲକ୍ଷଣ ଟ୍ରାକ୍ କର। Flo ସକ୍ରିୟ ସ୍ୱାସ୍ଥ୍ୟ ଗ୍ରାହକକୁ ଲକ୍ଷ୍ୟ କରେ; Period Calendar ସେହି ବ୍ୟବହାରକାରୀକୁ ଲକ୍ଷ୍ୟ କରେ ଯିଏ ସରଳତାକୁ ସବୁକିଛିରୁ ଉପରେ ଚାହାଁନ୍ତି।
ସେମାନେ ଯାହା ଅଂଶୀଦାର କରନ୍ତି ସେହିଟି ହେଉଛି ଗୋପନୀୟତାର ଖାଲିକା। Flo ର ଗୋପନୀୟତା ଫେଡେରାଲ୍ କୋର୍ଟରେ ଦଲିଲ କରାଯାଇଛି। Period Calendar ର ଗୋପନୀୟତା ଏହାର ବ୍ୟବସାୟ ମଡେଲରେ ଅନ୍ତର୍ଗତ — Google ବିଜ୍ଞାପନ ଏସଡିକେ ଚାଳନା କରିବା ସମୟରେ କୌଣସି ତଥ୍ୟ ସଂଗ୍ରହ କରିବାର ଦାବି କରେ।
Privacy comparison
Flo's privacy failures are the most documented in the industry. An FTC order in 2021, a class action Flo settled for $8M in 2025, and a California jury verdict against Meta for eavesdropping on Flo users' data. Flo denies wrongdoing, and no court has found that it broke the law.
Period Calendar's privacy situation is different but concerning. The app markets itself with bold "we don't collect or store your data" claims. But it's ad-supported through Google Ads, DoubleClick, and AdMob. Privacy International documented heavy third-party network traffic to Google advertising services despite the local storage claims. Advertising SDKs collect device identifiers, usage patterns, and behavioral data by definition — that's how ad targeting works.
The pattern is the same: both apps say one thing about privacy and do another. Flo's contradiction ran for nearly three years before the press caught it. Period Calendar's contradiction is structural — you cannot simultaneously claim "no data collection" and run ad networks that require data collection to function.
PinkyBloom eliminates the contradiction. No ads means no ad SDKs. No accounts means no identity linkage. Your cycle log is stored on your phone, protected by your phone's own encrypted storage.

Pricing comparison
Flo charges ~$49.99/year for premium. Period Calendar is free with ads and optional paid upgrades. The cost difference is significant — Flo is among the most expensive period trackers; Period Calendar is among the cheapest.
But the real cost includes what you pay beyond money. Flo costs subscriptions and, for nearly three years, your data. Period Calendar costs your attention (ads) and potentially your data (ad SDKs).
No ads, no hidden data costs. More features than Flo, simpler than Period Calendar, and never sold.
There's a better option
The two most-downloaded period trackers both have privacy contradictions — Flo's documented by the FTC, Period Calendar's embedded in its ad model. PinkyBloom is the zero-contradiction alternative: no ads, no account, never sold. More features than Flo, simpler setup than Period Calendar.
