Everything in one place

Made for the way cycles actually feel

Not just dates on a calendar — Cyria reads your patterns and turns them into calm, useful guidance.

Smart cycle predictions

Period, fertile window and ovulation estimates update as you log — see “next period in 30 days” at a glance on the cycle ring.

Beautiful calendar

Month and year views mark period, predicted period, estimated ovulation and fertile days — with cycle history a tap away.

Log what matters

Flow, period pain, symptoms, mood, intimacy and notes — every section is optional, and saving takes one tap.

Trends & insights

Cycle length, period length and day-to-day variation over time — “your cycle is generally regular,” backed by your own data.

Daily tips

Gentle, cycle-aware guidance for today — what you might feel, what can help, and what to keep tracking.

Reminders that respect you

Period and tracking reminders you control — off by default, easy to tune, never noisy.

Privacy first

Your health data is yours. Even the ad-funded parts.

Health data is some of the most personal data there is. Here’s how Cyria handles it — honestly, including where our control ends.

✓ Ads that never see your cycle

Advertising partners may receive standard device identifiers to serve and measure ads — that’s the full list. Your health data — the period dates, symptoms, moods and everything else you track — is never part of it: not sold, not shared with advertisers, regardless of any settings.

✓ Analytics for a better Cyria, not a profile of you

With your consent, we look at anonymized account and usage data — never health data — to see which features help and where people get stuck. One purpose only: a better product and a smoother experience for you.

✓ Honest about security

We implement technical and organizational measures in an effort to protect your data. Though we can’t guarantee that misuse or loss will never occur, we use all reasonable efforts to prevent it.

✓ What we do — and don’t — hand over

We never sell your health data — and we never hand it over to third parties. Running an online service still means relying on partners like hosting providers; an incident on their side is something we can’t fully control. If anything ever touches your data, you’ll hear it from us first.
