## What is RYTEX?

Know Your Rhythm.

RYTEX is a private, ad-free period and cycle tracker.
Your health data lives on your device — always.

TRACK YOUR CYCLE
• Period & ovulation predictions
• Symptom tracking (mood, cramps, energy, sleep and more)
• Daily & monthly cycle insights
• Irregular cycle support

PLAN AHEAD 
See your predicted period dates for the next 3 and 6 months.
Plan your vacation, your important days, your life —
without surprises.

PARTNER SHARING
• Share your cycle privately with your partner
• Sharing starts only with your invitation and their explicit acceptance
• End-to-end encrypted — no one can read it, not even us
• You control what they see, and you can stop sharing anytime

TRULY PRIVATE
• Your health data stays on your device
• Anything you share is end-to-end encrypted
• No ads. Ever.
• No data selling. Ever.
• No account required to start

HEALTH INSIGHTS
• Science-based cycle analysis
• PMS & ovulation pattern detection
• Doctor report export (PDF)

SPARK 
Something your partner can send you.
Something you can send back.
Only visible when you open the app.
No notification. No trace.

Some things don't need words.

DISCREET BY DESIGN 
All notifications are private.
No period dates. No symptom details. No cycle info.
Just a gentle nudge — nothing more.

Your health is yours alone.

Apple Health: RYTEX can import your past Menstrual Flow records from the Health app (read-only) so you keep your history when switching from another period tracker. Settings → Data Transfer → Import from Health.

## Version history (last 5 releases)

### 1.2.2 — 2026-08-23

• Fixed: SPARK history could look empty when your connection was weak.
• Sending and reply errors now tell you the reason.
• If you don't track your own cycle, settings that don't apply to you are hidden.
• Speed and stability improvements.

### 1.2.1 — 2026-08-17

• Cleaner symptom screen: sections are clearly separated and the selection cards are wider.
• Labels now read fully in every language.
• Fixed the version shown in Settings › About.

### 1.2.0 — 2026-08-13

• RYTEX Premium: partner sharing and SPARK are now part of Premium. Everything else stays free — cycle tracking, calendar, symptoms, insights, doctor report and backup.
• 14 days free: every feature is open for two weeks.
• Already using RYTEX before this update? Premium is on us for a year.
• Three new languages: Dutch, Swedish and Norwegian.

### 1.1.0 — 2026-08-10

• You can now correct when your period ended: tap a day inside it and choose "Ended", or extend it the next day with "Still on my period".
• Spotting between periods can be logged: it shows as a small dot on the calendar, and repeated spotting raises a health flag.
• Reminder notifications on iPhone are fixed, and tapping one takes you straight to the reminder it was about.
• The selected day in the calendar is now visible on period days too.
• Fixed an issue that prevented sending a SPARK to your partner.
