Data handling

The server answers from the same published information as this website. It does not store the questions sent to it, the tool inputs or any conversation content. To prevent abuse it keeps a short-lived request counter keyed to a one-way hash of the caller’s network address, which expires after one minute. Like every page on this site, requests appear in standard web server logs. See our privacy policy 및 data use terms.

Support

Questions about the server or the funds: call (844) 875-2288 or contact VistaShares.

For information only; not investment advice or an offer to buy or sell shares. Investors should consider each fund’s investment objectives, risks, charges and expenses carefully before investing. The prospectus contains this and other information and should be read carefully before investing; it is available on each fund page. Investments involve risk, including possible loss of principal. ETF shares are bought and sold at market price, not net asset value.
