Terms of Use

Last updated: 20 September 2026.

By using K&J Stack, you agree to use the site as an informational tracking tool. Market prices, currency rates, calculations and portfolio values may be delayed, unavailable or inaccurate.

No financial or appraisal advice

Nothing on K&J Stack is financial, investment, tax, legal or professional appraisal advice. The service does not make an offer to buy or sell precious metals. You are responsible for checking important values with an appropriate dealer or professional before making a transaction.

Data and backups

Your portfolio is stored in your browser. Browser data can be lost or cleared, so you are responsible for exporting backups you wish to keep. K&J Stack cannot recover locally stored holdings from another device or a cleared browser.

Availability

The service may change, experience interruptions or rely on third-party data sources that become unavailable. No guarantee is made that the service or any particular data feed will always be available.
