Transparent planning starts with accountable publishing.

Ownership and responsibility

ETF Compass is published by Lambda Software. Lambda Software maintains the calculator, the source-backed learning material, and the contact path for questions and corrections.

Editorial responsibility

Lambda Software is responsible for ETF Compass and its model explanations. The organizational byline identifies the publisher; it does not claim regulated adviser status or a professional finance qualification.

How content is prepared

Articles begin with the behaviour implemented in the calculator and explain it in plain language. Time-sensitive facts are checked against primary public sources, linked at the end of the relevant article, and accompanied by an update date. Worked examples are illustrative and must be reproducible from the stated inputs.

Lambda Software separately publishes engineering notes about calculation validation and local-first product boundaries. Those notes document how the product is tested and maintained; the ETF Compass guides remain the canonical educational articles.

Corrections and updates

If a formula explanation, source, translation, or factual statement needs correction, email lambda.softwarepg@gmail.com with the page and issue. Material corrections should update the visible review date.

Advertising and editorial independence

Advertising is disabled while the site is under review. If Google ads are enabled later, advertising will remain separate from calculator results and will not determine article conclusions, assumptions, or source selection.
