What you can do in Furuwaku on the web
Limit estimator with a safe band
Salary, spouse, dependents, social insurance and iDeCo run through the standard resident-tax formula to produce a standard ceiling and a conservative 85% band.
One ledger above every portal
Rakuten, Furusato Choice, Satofull, Furunavi and Amazon each remember only their own orders — log them all here, grouped by municipality and filterable by portal and year.
One-stop paperwork checklists
Form received, filled, ID copies attached, mailed, arrival confirmed — per donation, with the January 10 deadline and the days remaining on every card.
Five-municipality warning
A five-dot gauge that turns amber at the cap and red past it, because a sixth town silently kills one-stop for the whole year.
Year-end allowance ring
Yen remaining against your estimated ceiling, countdowns to December 31 and January 10, and every donation whose paperwork is unfinished.
Return-gift log
What arrived, what it cost in allowance and your own notes — so you never re-order a dud, and always re-order the good one.

Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a Furuwaku app for iPhone or Android?+
Not yet. Furuwaku is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
