Your first portable checkpoint

Start your Mini Backpack.

Give it a name and a purpose. It stays in this browser unless you deliberately export a copy.

Know where it lives before you begin.

This release stores readable data in your browser’s local storage on this device. Signing in elsewhere will not retrieve it. Clearing browser data or losing this device can erase it unless you keep an exported copy. Do not enter passwords, account numbers, addresses, child identifiers, medical details, sealed records, or confidential legal material.

Checking this browser for an existing Mini Backpack…

Checking local storage…

Carry it manually.

Export makes a readable JSON file with schema version 1 and a SHA-256 integrity receipt. Import checks the file type, schema, required fields, storage boundary, Backpack ID, and digest before replacing the local copy. Invalid or altered files fail closed and are not saved.
