The app
The app at /app/ runs entirely in your browser. Your sessions, trades, notes, settings and indicator scripts are saved in your browser’s own storage on your device. They are never sent to us, and we cannot see them. Clearing your browser data for this site deletes them.
To draw charts, the app downloads price candles directly from Binance’s public market-data service. Binance therefore sees your IP address and which market you asked for, as with any website you visit.
The site
We count page views with Cloudflare Web Analytics. It uses no cookies and does not identify or follow individual visitors.
Our hosting provider, Cloudflare, processes your IP address in order to deliver pages, as every web host does.
Advertising
Guide pages may show ads from Google AdSense. When they do, Google and its partners may use cookies to show and measure ads, including ads based on your earlier visits to this and other websites. Where the law requires it, you are asked for consent first and can change your choice at any time from the consent message. You can also manage ad personalisation in Google’s Ads Settings.
The app shows no ads and sets no advertising cookies.
Referral links
Some guides link to exchanges with referral links, each labelled as one. If you follow one, the exchange learns that you came from Nendojo. We receive no personal information about you from the exchange.
Donations
If you donate, the payment is handled by your bank, the blockchain network or GitHub. We see only what that channel shows a recipient.
