PERIOD. never does. No advertisers. No data trade. Period.Cycle apps have repeatedly been caught sharing menstrual and pregnancy data with advertisers and big tech. Regulators stepped in. Lawsuits followed. PERIOD. doesn't play that game. - 02 ### Built by Lisa The industry designs apps to look 'feminine' rather than to actually work for women. PERIOD. is Lisa's idea. She uses it herself, every month, and knows exactly what's missing.Pink tones and floral icons aren't product design for women. - 03 ### Clarity first Everything you need at a glance, in plain language: where you are in your cycle, what your body is doing and what you can expect. No clutter, no pop ups, no scare tactics. Understanding your own body should be simple.You choose how the app talks to you, and it learns from your own cycles. - 04 ### 100,000+ women chose it before you The first 10,000 arrived in less than two weeks, organically, without ad spend. Not because we're big, but because it works.‘So nice to finally be able to log everything, without your data being sold. The app works really well and gives good tips.’ SHCup, App Store review Sources: regulator findings and public reporting on the cycle tracking industry. ## What you get in PERIOD.

MaudS96 · App Store Really a good app > Really a good app where an ad for the pro version does not pop up every two seconds. You can tell it was made by a woman for women, and every time you open the app you learn something new about your body. I found the app through a TikTok from the maker and deleted Flo, which I had used for years, straight away. Really great, more women like this in our world please! 🩷 dunia0401 · App Store Extensive, personal and professional > An app for women, made by and with women, and you can tell in everything. It is well put together, with extensive options to track your period and over time even personal predictions. What a breath of fresh air this app is. Thanks for making it! 💗 Noortje84 · App Store Perfect > Amazing app! Clear, informative, transparent and easy to use. I immediately deleted my old cycle app Clue. Really reassuring that my data is finally treated confidentially. Kierie · App Store Best app for your cycle > Really lovely app. One that simply looks calm, asks the right questions and gives good tips. And so nice that it comes without weird ads.
