Privacy and data choices.
Essential preferences
zcompound stores your language, appearance, and saved-reading choices on your device so those features work. The calculator runs in your browser and does not save the amounts you enter.
Optional measurement
With your permission, Google Analytics measures page views and broad feature interactions such as opening a guide, using site search, or visiting the calculator. zcompound does not send search text, calculator amounts, names, email addresses, advertising identifiers, or financial account data through these events. Google Signals and ad personalization are disabled.
Optional third-party market data
The site includes a first-party market reference map and tape without contacting TradingView. If you choose to load third-party market data, the same saved consent enables TradingView in both the global tape and the homepage board. TradingView can receive this page URL, the widget type, displayed symbols, and your IP address. TradingView says its widgets do not set cookies. Quote timing varies by instrument and venue and may be real-time, delayed, or end-of-day.
You can turn live data off from either the global tape or homepage board at any time. Both controls update the same choice saved in this browser and prevent the TradingView script from loading on later page visits unless you enable it again. See the TradingView widget privacy FAQ.
User-initiated machine translation
English and Vietnamese are zcompound’s reviewed editions. Opening the language menu loads Google’s available-language list on demand. Choosing another language translates the visible page with Google’s website-translation code. Google can receive the page URL, your IP address, and browser data. Your choice is stored in language cookies so it can be restored on a later visit; choosing English or Vietnamese removes the Google translation cookie. Machine translation may contain errors, especially in financial terms.
Change your choice
Use “Analytics choices” in the footer at any time. Choosing “No thanks” stops optional measurement on that browser and removes the first-party Google Analytics cookies that zcompound can access. The separate market-data choice can be changed from either the global tape or the homepage board.
