The short version
iost.asia is a static information site. You cannot create an account here, there are no forms to fill in, and we do not run advertising, analytics trackers or tracking cookies. We do not build profiles of visitors and we do not sell data.
The site does show live data, such as the IOST price, exchange rates and blockchain lookups. Our server does not fetch that data for you. Instead, small scripts in your browser request it directly from public services. That means those services receive a normal web request from your device, including your IP address, and their own privacy policies apply to it.
Public APIs your browser calls
These are the only external services the site’s scripts contact. Pages with a live price or converter call the market and currency-rate services; the three blockchain endpoints are used only by the explorer widget, for example on our IOST explorer page.
| Service | Address | What it is used for |
|---|---|---|
| CoinGecko API | api.coingecko.com | IOST price, market data and charts |
| Binance market data API | data-api.binance.vision | Backup IOST/USDT price if CoinGecko fails |
| jsDelivr CDN (currency-api) | cdn.jsdelivr.net | USD exchange rates for local currencies |
| ExchangeRate-API | open.er-api.com | Backup exchange rates |
| IOST mainnet node API | api.iost.io | Network status, transactions and accounts |
| IOST Layer 2 RPC | l2-mainnet.iost.io | Layer 2 status and lookups |
| BNB Chain RPC | bsc-dataseed.bnbchain.org | BEP-20 IOST address and transaction lookups |
Fonts and images are served from iost.asia itself, not from third-party font services.
When you use the explorer, whatever you type, such as a transaction hash, an IOST account name or a 0x address, is sent to the matching blockchain endpoint so it can return the result. Blockchain data is public by design, but the service you query can link your lookup to your IP address. If that matters to you, avoid pasting your own addresses, or check them on an official explorer of your choice. Our price page and converter only request market and currency data; amounts you enter in the converter are calculated in your browser and never sent anywhere.
What is stored on your device
To avoid asking the same APIs again on every page, the site keeps a short cache of public market data in your browser’s sessionStorage. Prices are kept for about 90 seconds, chart data for about 10 minutes and exchange rates for about an hour. The cache holds only public data, never anything about you, and your browser deletes it automatically when you close the tab. We do not set cookies or use localStorage for tracking.
Hosting logs
Like almost every website, iost.asia is served by a hosting provider whose servers keep standard technical logs. These typically include your IP address, the page requested, the time, and your browser’s user agent. They are used to deliver the site, keep it secure and diagnose errors. We do not use them to identify or profile individual visitors.
If you email us
If you write to support@iost.asia, we receive your email address and whatever you include in the message. We use it only to reply and, where relevant, to fix the page you wrote about. We do not add you to a mailing list, and we do not share your message or address with anyone without your permission. You can ask us to delete your correspondence at any time. More about how we work is on our contact page and about page.
External links and changes
Our pages link to exchanges, regulators and block explorers. Once you follow a link, the other site’s privacy policy applies, including when you click a button to an exchange such as the ones described in our disclaimer. If we ever change how the site handles data, for example by adding a new data source, we will update this page first. Questions about privacy go to the same address as everything else: support@iost.asia.
