Your files stay on your device
When you open a file in the CSV converter or the cost basis calculator, your browser reads it and works through it inside the page. The file and its contents are not sent to us. The converted file you download is created in your browser too.
To check it yourself, press F12 in most desktop browsers, open the Network tab and load a file: nothing that is sent contains it.
When you pick a country in the cost basis calculator, it asks our site for that currency's daily exchange rates. Only the currency code is sent, nothing from your file.
Live rate pages
Rate pages refresh their prices from our site once a minute; each refresh sends nothing about you beyond what opening any page sends.
The calculator on the rate pages works out its answer on our site: each time you change it, the amount you enter, whether you buy or sell, whether the amount is in USDT or local currency, and the payment method you pick are sent to our site in the web address the calculator uses to get the price. Like any page visit, that shows up in the basic visit information described below; we don't store these amounts anywhere else or link them to you. Your choice is also kept after the # in the page's address so a reload shows the same answer; that part stays in your browser.
The one thing you can choose to send
If the converter doesn't recognize a file, it shows a "Send column names" button. Pressing it sends only the column names from the top of the file (no amounts, dates or addresses), so we can add that kind of file. Nothing is sent unless you press the button.
What we see when you visit
Like any website, our hosting provider and we see the basic information every browser sends: your IP address, browser type, the page you opened and the time. The site is delivered through Cloudflare, which processes this information to serve and protect the site. Pages use the fonts already on your device, so no font service is contacted.
Visit counts
To see which pages people find useful, the site counts three things: a page being opened, a click on the referral link in our sign-up guides, and a click on a "Copy" button next to the referral code. Each one adds 1 to a daily total for that page and country; the country comes from Cloudflare, which works it out from the connection. We don't store your IP address, set a cookie or keep anything that tells one visitor from another, so these totals can't be traced back to you.
Google Analytics
We use Google Analytics to see how many people visit, which pages they read and which country they come from. It sets cookies named _ga and ga followed by a code, and sends Google your IP address, your browser, the pages you open and two events: a copy of the referral code that worked, and a click on the referral link to Binance's sign-up page. What was copied is not sent. Google explains how it uses this information in How Google uses information from sites or apps that use our services. The site shows no ads.
Google Analytics is on by default. In the European Economic Area, the United Kingdom, Turkey and Serbia, where the law asks for consent before cookies like these, it starts switched off: no analytics cookies are set there, and Google only receives a signal without cookies that a page was opened.
To switch it off, use the button below. Your choice is kept in this browser's local storage (not in a cookie), and switching off also deletes any _ga cookies already set. To switch it off on every site, install Google's opt-out add-on.
Cookies
The site itself sets no cookies. Google Analytics sets the cookies described above unless it is switched off. Cloudflare, which delivers the site, may set a short-lived cookie when it checks whether a visit comes from a bot.
