Heartwood

The private box only the two of you can open.

Private By Design

Heartwood is an end-to-end encrypted box for a couple: photos and videos, your story timeline, private chat and voice notes, milestones, and sealed letters that open on a date you choose.

Everything is encrypted on your phone before it is uploaded. You and your partner compare a safety number once, so you can check for yourselves that nobody in the middle — including us — holds the key.

Yours To Keep

Export everything, free, on every plan. Paid plans add shared storage; they never gate access to your own memories.

Heartwood has no ads, no selling of data, and no third-party tracking SDKs.
