What it does
A link and a password
Share report makes a link at longbook.app/r/ and a password of three words and two digits. The moment the link is made, Report shared shows the link and the password side by side, each with a copy button, to be sent separately. The password is shown only then; longbook's server keeps only a hash of it.
Comments on each section
The report opens in a browser once the password is typed, and every section has its own comment box; a name is optional. Pull comments writes the comments into the report in your folder, under the section each one is about.
Three days, or sooner
A link expires 3 days after it is made. Stop sharing ends it sooner and deletes the shared copy and its comments from longbook's server. Shared with keeps a note of who has the link.
Why it exists
Household money is often looked at by more than one person: a partner, a parent, an accountant. A link shows one month without handing over the whole longbook, and the questions come back beside the numbers they are about.
Questions
What does the person I share with see?+
The one report, drawn as the app draws it. For a month longbook drew, that is Total expenses, Accounts, Categories and All charges. No other part of your longbook is sent.
Do they need longbook?+
No. The link opens in a browser and the password unlocks it; reading and commenting need no account. Only the person sharing signs in to longbook.
What if the password is lost?+
longbook cannot show it again. Stop sharing, then Share report once more for a fresh link and password.
