## What is Arythm?

She's tired of explaining her cycle. You're tired of guessing. Same problem.

Arythm syncs the current phase of her cycle to your phone — encrypted, partner-only. You see where she is and how to actually help, so she's supported without the emotional labor of explaining it again. Free for 7 days.

HOW IT WORKS
• She connects Apple Health or Oura — or just logs her period right in Arythm
• Her current cycle phase is encrypted on her device, end-to-end
• Only you see it — never the cloud, never us, never anyone else
• Lives on your home screen as a widget — no app-opening required, just glance
• You both get tips, body info, and a read on her energy

NO RING REQUIRED
• A simple shared calendar — she taps to log her period, that's it
• Arythm predicts her phase from her history, even with no wearable at all
• Already on Oura or Apple Health? It folds that in automatically
• One calendar, however she tracks — logged days and predicted days, clearly shown

BUILT FOR THE DAYS YOU CAN'T READ HER
• No more "I'm fine" when she's not fine
• You stop guessing why she's tired today
• She stops having to translate her body into your language
• You actually become helpful instead of confused
• Built for the days she needs you to just know

WHAT YOU SEE AS A PARTNER
• Her current cycle phase, updated automatically
• A calendar of where she's been and what's coming
• Tips for how to actually be supportive this week
• A read on her energy and rest — never raw numbers
• How long the current phase will last

PRIVACY IS THE PRODUCT
• End-to-end encrypted (AES-256-GCM, Curve25519 key exchange)
• No raw health data leaves her device
• The server only ever sees an unreadable blob — never your actual cycle data
• When you unlink, all shared data is deleted immediately
• No ads, no data sales, no third-party tracking

YOUR RING ALREADY KNOWS
• Best with Oura — temperature-based phase detection, no daily logging needed
• Works with Apple Watch cycle tracking too, through Apple Health
• Already use Flo, Clue, or Apple Health? Arythm reads from those automatically
• No wearable? Her own logging works just as well — nothing's gated behind a ring

PREMIUM
• Free for 7 days — see the whole thing before you pay a cent
• Then $3.99/mo or $24/yr — two bucks a month if you go yearly
• Partner pays, sharer has free access
• Cancel anytime

She doesn't have to explain. You don't have to guess. Arythm is the quiet, private way two people stay in sync.

TERMS
