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 leaves your phone. Your logs never do.
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 never leaves
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
End-to-end encrypted between your two phones. We never hold the key. Our relay forwards ciphertext it cannot open and keeps it for at most seven days. No phone number, no email, no account.
Want to see what the app itself sends home? Read the Receipt. For the longer version of the privacy argument, 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
Private entries never leave, 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.
Read morePregnancy
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
Peer to peer and encrypted end to end, iPhone to Android or either to its own kind. When a relay is needed it forwards packets it cannot read. No media server ever hears your call.
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.
