Share your cycle with one person. Decide exactly how far.
PinkyBloom is a period tracker you can share with your partner, free on both phones. You track here. He gets PinkyBond on his phone. What crosses between the two is a snapshot you set — the phase, the week ahead, a mood word if you allow it — encrypted so that nobody else, including us, can read it.
A snapshot goes to him. Your logs don't.
Most period apps that share with a partner hand him a copy of your calendar. PinkyBloom computes something smaller on your phone — a derived snapshot — and sends only that. It is enough for him to plan around. It is not enough to argue with.
What can leave
Your phase, an energy level from 0 to 5, a mood word, and a forecast of the week ahead. At Full, a status you write and — in perimenopause or menopause — your top symptoms.
What he never sees
Notes. Private entries. The symptoms you logged. Your conversations with Pinky. Your history. The dates behind the phase. None of it is in the snapshot at any level.
How it travels
在你的手机与他的手机之间端到端加密。我们从不持有密钥。我们的中继服务器只转发它无法打开的密文，一旦他的手机收到就会删除——如果他的手机一直离线，最多保留 30 天。没有电话号码，没有电子邮箱，没有账号。
For the longer version of the privacy argument, read how to share your cycle without giving up your privacy.
Basic, Mood or Full. You choose. He is never notified.
Three levels, set on your phone, changed whenever you like. Moving down a level is silent — his app simply shows less.
He sees
Your phase, or your trimester or recovery stage.
He does not
Everything else stays with you. His app still shows a mood and energy, predicted from your phase and labelled that way.
He sees
Phase, plus the mood and energy you logged today, and the week between you.
He does not
Notes, symptoms and dates stay with you.
He sees
Everything above, plus a status you write and, in perimenopause or menopause, your top symptoms.
He does not
He never sees private entries, even here.
The sharing follows you. So does he.
PinkyBloom tracks five life stages, and PinkyBond follows whichever one you are in. A period tracker for couples usually stops at the cycle. This one does not.
Cycle
Phase, energy, and the week ahead. He knows the week before it happens.

Nothing changes on his side until you choose to reveal it in the app. The reveal is yours to time.
Read morePostpartum
Recovery stage instead of phase. Your recovery feeds the forecast he sees.
Read morePerimenopause
The pattern, and at Full your top symptoms. No other tracker with a partner side follows you here.
Read moreMenopause
The partner side does not end at the last period. He keeps the week ahead and the thread.

Not a read-only card. A place the two of you talk.
Every other period tracker with a partner mode shows him a calendar and stops there. PinkyBloom and PinkyBond open a thread between your two phones, with voice and video calls, and the thread knows what week it is. He checks in too, so it goes both ways.
Messages
End-to-end encrypted between your two phones. We never hold the key. Notifications never carry your message; your phone decrypts it locally.
Calls
点对点并端到端加密，无论是 iPhone 对 Android，还是同类设备之间。需要中继服务器时，它只转发自己无法读取的数据包。任何媒体服务器都绝不会听到你的通话内容，也绝不会录制任何通话。我们的服务器会保留一份通话记录——谁拨打的、何时拨打、语音还是视频、如何结束——保留 90 天，以便未接来电能够送达关机的手机。
Identity
No phone number. No email. No account. The pairing is the identity, and a six-digit check lets the two of you confirm nobody sat in the middle.
How the pairing works on his phone: PinkyBond pairing.
Pause, in one tap
Sharing stops until you turn it back on. He is not notified. Lowering the level is just as quiet. Unpairing ends it on both phones; his app shows nothing.
Safety Mode
For when a relationship turns. Safety Mode replaces what you share with neutral placeholder data — a steady phase, an even mood, no status of your own — so “show me your app” has nothing to show. He is not told it is on.
Others share a calendar. This shares a channel.
Flo for Partners, Clue Connect and Stardust all let a partner see your cycle. Each gives him a read-only calendar or card, through the company's servers; Clue Connect also needs Clue Plus on your side. PinkyBloom and PinkyBond give the two of you a private channel built on the same signal — a thread, calls, a check-in of his own — free on both phones, encrypted between them, with you holding the dial.
Sharing a period tracker with your partner: the questions people actually type
Your cycle in. His week out.
PinkyBloom for you. PinkyBond for him. Free on iPhone and Android, no account on either side.
