Period tracker to share with partner

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.

What sharing means here

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.

The dial

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.

Basic

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.

Mood

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.

Full

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.

One thread, two phones

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.

Period apps for couples, compared

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.
