Privacy policy
Effective 13 September 2026.
The short version
Every calculator on Danfio runs inside your browser. The numbers you type — income, debts, balances, documents — are never sent to us and are never stored on a server. We have no accounts, no newsletter and no user database to leak.
1. What you type into a tool
Inputs stay in your browser's memory and, where a shareable link is useful, may be written into the page address (the part after the “?” in the URL). That address exists only in your browser tab until you copy it somewhere. Pressing reset, or reloading the page without the query string, removes it. We never receive a copy.
2. What we do not collect
- No account, email address or password is required to use any tool.
- No file you process is uploaded. PDF, image and text tools work on the file inside your browser.
- No data entered into a calculator is logged, profiled or sold.
3. Hosting and server logs
The site is served by a content delivery network, which keeps short-lived technical logs (IP address, user agent, requested page, timestamp) in order to deliver pages and block abuse. Those logs are generated by the host, are used for security and reliability, and are never combined with anything you type into a tool.
4. Advertising (Google AdSense)
This site is supported by display advertising served by Google and its partners. When ads are shown, Google may use cookies or similar technologies to serve and measure them, including personalised ads based on your previous visits to this and other websites. Google's use of advertising cookies is described in Google's ownadvertising policies.
- You can turn off personalised advertising inGoogle Ads Settings.
- In the EEA, the UK and Switzerland, personalised ads are requested only after you make a choice in the consent message shown on your first visit, delivered through a Google-certified consent management platform. You can change that choice at any time from the privacy settings link shown with the ads.
- Industry-wide opt-outs are available ataboutads.infoandyouronlinechoices.eu.
5. Analytics
We do not run analytics on the tools themselves. If aggregate traffic statistics are ever enabled, they will be limited to page-level counts — which page was opened, roughly where from, on what kind of device — and this page will be updated before that happens.
6. Children
The site is intended for adults making financial, home, tax or file decisions. It is not directed at children, and we do not knowingly collect personal information from children.
7. Your rights
Because we hold no personal data about tool users, there is usually nothing to export or delete on our side. If you believe we hold information about you — for example an email you sent us — write toDanfioTools@gmail.com and we will respond within 30 days. Requests about advertising cookies should go to Google, which controls that processing.
8. Changes to this policy
If the site adds a feature that changes any statement above — for example a newsletter or an optional cloud account — this page will be updated and the effective date changed before that feature ships.
