About this app

Red Alert is a menstrual cycle tracker for partners who want to pay
attention.

Enter the start date of her last period and the app maps out the month:
which phase she's in today, what commonly comes with it, and three
practical things you can do about it. No guessing. No awkward silences.

Built to be used openly, together — Red Alert works best when she knows
you're using it. It's a shared reference, not a secret one.


THE PHASES

🔴 Period — Time for care. A heating pad, her favourite comfort food,
and patience.
⚡ Follicular — Energy usually climbs. A good window for plans and real
conversations.
🌟 Peak day — Confidence and enthusiasm often at their highest.
🌙 Luteal — Frequently more introspective. Be present without pressure.
❤️ Premenstrual — Small gestures go a long way. Don't take mood shifts
personally.

Every phase description is general guidance. Every person is different,
and she is the authority on how she actually feels.

WHY IT HELPS

"What's wrong?" answered with "nothing" often isn't a communication
problem — it's a timing problem. Knowing that this week tends to run
low-energy doesn't make you a mind reader. It just means you stop
scheduling the hard conversation for the worst possible Tuesday.

Partners who pay attention are more present, more patient, and a lot
easier to live with.


PRIVACY

Everything you enter stays on your device. No account, no sign-up.
Google Drive backup is optional, off by default, and encrypted on your
phone before anything is uploaded — we never receive it and can't read
it. The app uses Google Analytics for Firebase to understand crashes and
general usage; this never includes the cycle dates, notes, or personal
details you enter.

IMPORTANT

Red Alert is an educational tool. Predictions are estimates based on
average cycle data and will not match every person. It is NOT a
contraceptive method, NOT a fertility treatment, and NOT a substitute for
medical advice. Consult a healthcare professional for anything
health-related.

Only track someone else's cycle with their knowledge and agreement.
Cycle tracker for couples. Understand her phases and show up when it counts.
