Sharing Boxes: How Couples and Families Can Inventory Together

Solo home-inventory accounts have a quiet death curve.

You start strong. You photograph the kitchen, label some boxes, feel like an organized adult. Then your partner reorganizes the storage closet without telling you. You don't see the new arrangement, the inventory drifts out of sync, and within a month it's wrong about half your boxes. You stop opening the app.

Two-person households quietly defeat single-user inventory tools. This post is about the feature we shipped to fix that.

What "sharing a box" actually means

A few terms first, because the model matters:

• Workspace — the top-level container. Most people have one ("Home"). Power users have several ("Home", "Storage Unit", "Parents' Place").
• Box — a single physical or logical container of items inside a workspace. Photographable, sharable.
• Box Share — a permission grant on a single box (or a whole workspace) to another AllKeep user.

The granularity is per-box. You can share the kitchen but not the bedroom. You can share a single moving box with your parents who are helping. You don't have to share everything to share something.

Why this matters: the partner case

Here's the real-life version:

• I log the kitchen, garage, and storage closet.
• My partner logs the bedroom, bathroom, and "her" closet.
• We share the kitchen with each other (we both cook), and the storage closet (we both lose things in there).
• We don't share each other's clothes closets. Why would we.

The result: one inventory, two contributors, zero duplication. When she puts the colander in a new spot and photographs it, I see the update on my phone. The "where is X" question essentially disappears.

This was a feature we built for ourselves first. Other users quickly told us it was the entire reason they'd started using the app.

The permission model

There are three levels:

Viewer

Can see boxes, items, photos, search. Cannot edit.

Use case: you want a family member to be able to find the spare car keys when they need them, but you don't want them reorganizing the inventory.

Editor

Can add, edit, and delete items in a shared box. Cannot delete the box itself, cannot change permissions.

Use case: your partner. Roommates. The most common share level in two-person households.

Manager

Editor permissions + can invite other people to the same box, change the box itself, transfer ownership.

Use case: a co-owner. Adult kids managing a parent's storage unit. Co-founders sharing a workshop inventory.

You can also revoke any share at any time, instantly. The other user loses access on next sync — no waiting period, no email chain.

Use cases we've seen

Couple splitting kitchen + garage

The default we expected. Two phones, one inventory. Both can add items, both see updates.

Parents and adult kids tracking storage

Less obvious but very common. An adult child has stuff in their parents' garage. The parents need to find it sometimes ("which box has your old college textbooks"). Adult child shares the relevant boxes as viewer — parents can find things, can't accidentally delete them.

Roommates sharing common areas

Three roommates, shared kitchen and living room. Each has their own bedroom workspace (private). The shared spaces are a multi-editor box — anyone can update what's in the kitchen pantry.

Splitting an estate

Sad but real. Family members tracking what's in a parent's home after a passing. Sharing the inventory turns a stressful logistics problem into a coordinatable one. We've had multiple users tell us this was where the app earned its keep for them.

What's coming

The honest "not done yet" list:

• Read-only public links — for things like estate sales, garage sales, "here's what I'm selling" listings. Currently shares require an AllKeep account on both sides.
• Archive mode — a way to "freeze" a shared box (e.g. when someone moves out) without deleting it.
• Notification controls — right now you get every change notification on a shared box. We're adding per-share filters.

Privacy and data

A few things worth saying clearly:

• We don't see your shared boxes any more than your private ones. Same encryption, same isolation.
• Photos in a shared box are visible to everyone in the share. This is obvious but worth saying — don't share a box and expect photos to be private from the people you shared with.
• Revoking a share immediately removes access on next sync. Cached data on the other person's device is wiped on next open.

Full policy: allkeep.org/en/privacy.

Set it up

If you already have an AllKeep account, sharing is in the box context menu — three dots → Share → invite by email. The other person installs the Android app or signs in on the web, accepts, done.

If you don't have an account yet — install the Android app, set up your first workspace, then invite a partner or family member to a single box. The "where did you put X" question won't be a question anymore.
