This site is designed to need almost nothing from you. No account exists. Calculator inputs travel in the page address and are computed per-request; we do not store them. Your Money Plan answers are computed on the page and stored nowhere. The Ask feature sends your question to an AI model to compose an answer from our own content and does not store the question.

正確に何が保存されているか

• あなたのブラウザ上のみ: your theme choice, language, and ★ saved pages live in your browser's local storage. Clearing browser data removes them. The language choice also sets a small preference cookie so pages load in your language.
• ご連絡いただいた場合: the contact form stores your message and, if you provide one, your email — used only to respond.
• 購読する場合: your email address, used only for the updates you signed up for; write to us any time to be removed.
• サーバーログ: standard, short-lived technical logs (IP, path, time) for security and rate-limiting.

広告 Cookie（開示）

If clearly-labeled advertising (such as Google AdSense) is enabled in the future, ad vendors may use cookies or similar technologies to serve and measure ads, including personalized ads where law and your settings permit; Google's use of advertising cookies is described at Google's Ads settings pages, and non-personalized options exist. Today, no advertising cookies are set by this site. This paragraph exists so the policy will not silently change meaning later.

私たちが絶対にしないこと

No selling of personal information. No third-party analytics trackers. No requirement to identify yourself to use any tool. No storage of your financial figures.

あなたの選択肢

Use the site without JavaScript (core pages still render), clear local storage at will, and contact us for deletion of any contact-form or subscriber record: /contact.
