Pairing is a one-time setup between two phones. After it's done, both of you can join the weekly check-in cycle. Entries you've already written before pairing stay private to you.

Couples mode is what unlocks the simultaneous reveal. It needs both of you to install the app and complete a one-time pairing.

How to pair

If you're sending the invite

Open the app. Go to Settings → Invite a partner.
Tap Share invite. Your phone's share sheet opens.
Send the link to your partner — iMessage, WhatsApp, email, whatever works for the two of you.

The link is good for 15 minutes. After that you'll need to send a fresh one.

If you're accepting an invite

Tap the link your partner sent.
iPhone or Android opens the app to the accept-invite screen.
Tap Accept.
Both phones show a 6-digit verification code.

Verify the code

Compare the 6-digit code on both phones — in person, on a call, however you can. The codes must match.

If they match, you're paired. Tap Confirm on both phones.
If they don't match, something went wrong with the pairing. Tap Cancel on both phones and try again from a different network.

The code is your protection against someone interfering with the pairing process. Two seconds of comparison, on both ends.

What changes after pairing

The check-in tab activates. From now on, entries you mark Shared are part of the weekly cycle.
Both of you can see each other's name and profile photo (if either of you set one).
If one of you has a Premium subscription, the other gets premium features at no extra cost. (Inherited Pro)

Pre-pairing entries stay yours

Entries you wrote before pairing were locked with your personal key. Your partner's phone never gets that key. The reveal only includes entries written after you paired — your earlier solo entries remain private to you.

Day-change requests

Either of you can change the check-in day:

Settings → Check-in day
Pick a new day
The other partner gets a notification: "Sam wants to move check-in to Wednesdays."
They tap accept or decline.
Accepted: the new day takes effect immediately. Declined: the original day stays.

Neither of you can change the day on your own. The structure is what protects both of you.

Unpair

Settings → Disconnect from partner → confirm.

What happens:

The shared key is destroyed on your phone. Your partner's phone is notified and the same happens on theirs.
Your check-in cycle stops. You go back to solo mode.
If you had inherited premium from your partner, that ends now.
Entries that were locked with the shared key can no longer be opened, including your partner's past shared entries on your phone. (Their entries on their phone are still readable — for them. Yours on yours, same.)

Unpairing can't be undone. Re-pairing later starts fresh — none of the past shared entries come back.
