DanfioYour privacy choices
Last updated .
The short version
A privacy-choices page usually means a dashboard of tracking switches. On this site most of those switches have nothing to control, because the architecture already made the biggest choice for you: every calculation happens in your browser, and the numbers you type never leave the device. The few choices that are genuinely yours are set out below, with the exact steps to use them.
The choices the local-first design removed
Opt-out controls exist on most sites because your input goes to somebody else's server first. Here it does not: income, debts, balances, contract text and the files you open are processed in your own device's memory, and not one of them is sent to us or to a third party. There is no "opt out of input profiling" switch because there is no input profile; there is no account and no mailing list, so there is no record to close. The one feature that writes input into a URL is the share link, and that text stays in your own tab until you copy it somewhere.
Preferences kept in your browser
Your browser stores a few choices of your own: the color theme, the light or dark setting, the currency symbol, and the tools you saved or opened recently. They live in this site's local storage, work on this device only, and are never sent to us. To clear all of them, delete this site's data in your browser settings; the pages keep working, and the preferences simply return to their defaults.
Page counts, without cookies
We look at aggregate traffic: which page was opened, from which country, on what kind of device. Those numbers come from Cloudflare Web Analytics, which sets no cookie, stores nothing in your browser and builds no profile of anyone - it counts pages, not people. None of it comes from what you do inside a tool. If your browser or an extension blocks the analytics script, every tool works exactly the same: that is the simplest and most complete privacy switch you have.
Advertising, today and later
No advertising code is running on this site at the moment: no ad script, no advertising cookie, not even a reserved ad slot. So there is no advertising consent banner to accept or refuse today, because there is nothing to consent to. If Google AdSense begins serving ads later, the personalized-ads switch will sit in Google's own ad settings rather than here; before that happens, this page, the privacy policy and the date at the top of both will change first.
Selling or sharing personal information
Several US state privacy laws require a site to say whether it sells or shares personal information, and to offer a "Do Not Sell My Personal Information" route. The honest answer for this site is that nothing is sold and nothing is shared, not because a request arrived and we stopped, but because we hold no customer database and tool inputs never reach a server. There is nothing to sell, so there is no decorative opt-out button to press.
Other ways to exercise your rights
Technical server logs are produced by the content delivery network for security and reliability, and their retention and access are governed by the host's policy. Cookies, site data, blocking and tracking settings all belong to your browser, and clearing this site's data takes effect immediately. If you believe we hold something about you - an email you once sent us, for example - write to contact@danfio.comand we will answer within 30 days. Requests about advertising cookies should go to Google, which controls that processing.
