## What is Cycle Cipher?

Cycle Cipher is a private, local-first period and cycle tracker. Log the details that matter to you without creating an account, seeing ads, or sending health entries to the developer.

TRACK YOUR CYCLE

- Record period flow and daily notes.
- Log symptoms, moods, sexual activity, and basal body temperature.
- Review your history in a clear calendar.
- See cycle and period-length summaries based on the data you enter.

PRIVATE BY DESIGN

- Health records stay in the app's local container.
- Optional PIN and device authentication protect access.
- No advertising, analytics, accounts, or developer-operated cloud sync.
- Create password-encrypted backups and CSV copies when you choose.

REMINDERS ON YOUR TERMS

Choose optional on-device reminders and manage notification permission at any time. Cycle estimates are based only on past entries and may be early, late, or unavailable.

SENSITIVE HEALTH HISTORY

Privately record pregnancy tests, pregnancy outcomes, provider visits, contraception changes, and related dates. These entries are personal records, not medical guidance.

FREE FOR EVERYONE

Every feature is available for free. Optional, repeatable tips are processed by Apple and never unlock features or change app behavior.

Cycle Cipher does not diagnose conditions, provide treatment, or replace a qualified healthcare professional. Fertility and ovulation estimates are approximate and must not be used as contraception. Seek urgent medical help when you are concerned about severe or emergency symptoms.
