FAQ
Where is my data stored?
Everything is stored on your device. There is no account linking, cloud sync or sign-up, and your asset data is never sent anywhere.
How does pricing work?
The asset ledger and net-worth trend are free. Premium asset classes, the inventory PDF, the inheritance-tax estimate and CSV export are unlocked with a one-time ¥3,000 Full Access purchase.
Can the tax estimate be used for filing?
No. It is a personal simulation of the total inheritance tax and does not reflect the spousal credit or special provisions. For official filings, consult a professional such as a tax accountant.
This app is a general informational and educational tool. It does not recommend or solicit financial products, nor provide tax or investment advice. The inheritance-tax figure is a rough estimate of the total tax and differs from any actual filing.
