Effective October 22, 2026. This notice describes the current SimpleFinCalc website.
Calculator inputs stay in your browser
The calculators run in browser JavaScript. We do not send the amounts you enter to a calculation API or store them in a database. There are no financial-account connections or user accounts. CSV files are generated in your browser when you select Download.
We do not save your financial inputs in local storage or put them in shareable URLs. Reloading a page restores the illustrative example. Links may include a named example identifier, which contains no personal amounts.
Theme preference
If you change the light/dark mode, the site stores your choice in your browser under sfc-theme. This preference is local to your browser and is not an advertising identifier. You can remove it by clearing this site’s browser data.
Hosting and access information
The site is intended for Cloudflare hosting. Like other hosting services, Cloudflare can process technical request information such as IP address, requested URL, browser details and time for delivery and security. See Cloudflare’s privacy policy. Calculator amounts are not part of the requested URL.
Advertising and analytics
This launch does not load Google advertising scripts, marketing cookies or an analytics SDK. An AdSense ownership meta tag or ads.txt record, if present, is a static verification record and does not itself serve an ad. If advertising or analytics is activated later, this notice and any necessary consent controls will be updated before activation.
Contact email
If you email yjh@dgvantage.com, your address and the content you choose to send are processed by the mailbox service to handle your request. Do not send sensitive financial documents. Messages may be retained as needed to resolve a report and maintain a record of corrections. You can contact the same address to request deletion, subject to any applicable retention obligations.
External links and saved files
Links to reference sites are subject to their own privacy practices. CSV exports you save may contain the amounts and subscription names you entered; you control where those files are stored or shared.
