Is this basically a calendar app

A calendar app can record dates but cannot predict future cycles or identify patterns. A period tracker with cycle prediction algorithms does the math that turns past dates into future estimates. The core difference is prediction, not recording.

Can I use Floriva without internet access

Yes. Floriva works entirely offline. No internet connection is needed for tracking, predictions, or any core feature. The app never contacts a server because there is no server to contact.

What happens if I forget to log a period

The prediction adjusts based on the data you do enter. Missing one month of data does not break the algorithm. It recalculates using the cycles you have recorded. The predictions become less accurate with gaps, but they self-correct when you resume logging.

Digital Period Tracking for People Who Prefer Paper

For people tracking cycles on paper who want digital predictions without surveillance. How on-device apps deliver predictions without cloud accounts.

Why Paper Trackers Are Skeptical of Apps If you have been tracking your period on paper, in a notebook, on a wall calendar, or not tracking at all, you probably have a reason. Maybe you tried Flo or Clue and were put off by the account creation, the data collection, or the news about health data being sold. Maybe you do not like the idea of an app company knowing your cycle. Maybe you just prefer simple tools that do not require a login. These are reasonable positions. Most period tracking apps are designed to collect as much data as possible because more data means better advertising targeting or more valuable research datasets. The apps feel invasive because they are. The signup screen, the email verification, the "allow notifications" prompt, the mood tracking, the sexual activity logging: these features generate data that the company monetizes. What a Minimal Digital Tracker Looks Like We built Floriva for people who want the math without the surveillance. Here is what the experience looks like. You open the app. There is no signup screen. You tap to enter the start date of your last period. That is it. You are tracking. After your next period, you enter that start date too. Af
