Storage you control

Use Save scenario only if you want the browser to retain your planning data locally. Browser storage is not encrypted by this application and may be visible to others using the same browser profile. Use the available clear/reset controls and browser settings to remove stored records.

Downloads and network requests

Exports are generated locally. Shared sample links do not include your entered financial amounts. Static hosting still receives ordinary web requests such as IP address and user agent according to the host's own policy. External IRS links leave this site.

Third parties

Google AdSense account verification and manual educational-page placements are prepared, but no advertising script or live request is active. Financial workspaces have no ad placement. Live serving requires an appropriate consent platform and updated privacy disclosures; financial inputs must never become advertising or analytics parameters.
