Best Simple Period Trackers With No Surveillance (2026)
We compared 5 minimal period trackers for users who want cycle predictions without data collection or complex features. Ranked by simplicity and privacy.
Floriva is the simplest private period tracker: no account, no internet required, just enter your period dates and get predictions. Drip and Euki are also minimal and on-device. Avoid Flo, Clue, and Glow if you want a tracking tool, not a data collection platform.
How We Evaluated
We prioritized simplicity: how fast can you go from installing the app to having a working tracker? We disqualified any app that requires more than 2 minutes of setup or demands personal information before you can start tracking. Then we checked privacy: on-device storage, no accounts, no third-party analytics code.
The target user here is someone who has been tracking on paper (or not tracking at all) and wants the prediction benefits of digital without the data collection overhead of mainstream apps. Feature richness was scored negatively when extra features added complexity without improving core tracking.
The Simplicity Problem With Most Period Trackers
Most period trackers are designed to maximize engagement, not minimize friction. Flo greets you with account creation, email verification, health profile questions, notification permissions, and a premium upsell before you can log a single period. Clue asks for your birth date, cycle history, and creates a server-side account.
This design serves the company, not the user who just wants to know when her next period starts. If you have been using paper because digital felt like too much, these apps confirm your instinct.
What Minimal Actually Means
A genuinely minimal period tracker should work like a calculator. You open it, input data, get a result. No login screen, no onboarding flow, no daily notifications asking you to log your mood. The five apps in this comparison represent the simplest options available, ranked by how close they get to that calculator experience.
Floriva gets closest because we built it specifically for this use case. We asked ourselves: what is the minimum viable period tracker for someone who values simplicity and privacy above all else? The answer was start-date tracking with automatic predictions and nothing else required.

Quick answers to the obvious questions.
What is the simplest period tracker that does not collect data
Floriva requires the least setup: open the app, enter your last period date, and start tracking. No account, no email, no internet connection needed. Predictions work from start dates alone. You can ignore every optional feature.
Do I need to log symptoms every day for accurate predictions
No. Cycle predictions are based on period start dates, not daily symptom logs. Logging symptoms is useful for identifying patterns (like PMS timing) but is not required for the core prediction to work. All five apps generate predictions from start dates alone.
What does 'no surveillance' mean for a period tracker
It means the app does not embed advertising or analytics SDKs that send user behavior to third parties, does not require an account that ties cycle data to an email or phone number, and does not sync data to company-controlled servers by default. The 2021 FTC action against Flo documented exactly the kind of SDK-layer data sharing that 'no surveillance' apps are built to avoid. Health data flowed to Facebook, Google Analytics, and AppsFlyer despite policy language to the contrary.
Questions people ask before they switch.
Is Apple Health good enough for period tracking?
For basic cycle tracking, yes. Apple Health records period dates and generates predictions. It lacks the symptom pattern analysis and dedicated interface of a purpose-built tracker, but if you already have an iPhone and want zero extra apps, it works. Disable iCloud Health sync if privacy is your priority.
Can I export my data from Floriva?
Yes. You can export your cycle data as a file you control. Since the data is on your device, you can also simply note your start dates in any format you prefer as a backup.
Why would I switch from paper if these apps are so minimal?
Predictions. Paper records your period dates but cannot calculate when your next period will start, when your fertile window is, or whether your cycle has been getting shorter over the past year. That math is the main reason to use a digital tracker.
