About K&J Stack

K&J Stack is a browser-based precious-metals portfolio tracker for people who want a simple way to record bullion, coins, jewellery and scrap metal and compare purchase cost with estimated live melt value.

No account is required. Portfolio entries are stored locally in the visitor's browser rather than in a K&J Stack user database. The export and import tools allow users to create their own portable backup.

What the tracker covers

The tracker supports gold, silver, platinum and palladium, multiple purity standards, grams, kilograms and troy ounces, and GBP, USD and EUR display currencies.

What it does not do

K&J Stack does not buy or sell metals and does not provide investment, tax, legal or appraisal advice. Displayed values are estimates based on third-party market data and may differ from executable dealer prices.
