Terms of Use

Effective 2026-09-25.

The site and what it promises

Prism Data Lab publishes data analysis, methods articles, code listings, and data files about finance and machine learning for readers to learn from. What is published here is checked with care, and every article names its sources — and still, everything here is provided "as is," without warranty of any kind. Facts move; a published date tells you when a page was last checked, not that nothing has changed since.

Not advice

Nothing on this site is investment, tax, accounting, or legal advice, and nothing here is a recommendation to buy, sell, or hold anything. Articles analyse public data for educational purposes. Markets move; a figure is accurate as of the date and source cited and may be stale when you read it.

Who this site is for

This is a general-audience reference site. Nothing here requires an account, a purchase, or any personal information, so there is no minimum age to read a page. The published email address is for correspondence with adults: if you are under 13, ask a parent or guardian to write on your behalf rather than emailing yourself.

Acceptable use

Read, quote with attribution, and link to any page freely. The code listings are published under the MIT License unless a listing says otherwise; the data files may be reused with a link back to the article they came from. Do not scrape the site at volumes that degrade it for others, misrepresent its content as your own, or frame it in a way that misattributes it.

Intellectual property

The site's original text, design, code, and artwork belong to Prism Data Lab. Third-party names and marks mentioned in articles belong to their owners and are used only to identify what is being discussed.

No accounts, no purchases

This site sells nothing and never asks for credentials of any kind. Anything elsewhere claiming to be this site and asking for a login or payment is an impersonation.

Liability

To the maximum extent permitted by law, Prism Data Lab is not liable for any damages arising from use of this site, its code, or its data.

Changes

These terms change only when the site's practices do; the effective date above moves with any change. Questions: contact.
