Yesterday's Price is a free daily game operated by WheyDev LLC. By playing, you agree to these terms. They're short on purpose.
The game is for fun
Every price comes from real U.S. Bureau of Labor Statistics data pulled through FRED, and we take care to get it right — but the game is entertainment, not financial, historical, or economic advice. Don't rely on it for anything that matters.
Provided as is
Yesterday's Priceis provided “as is,” without warranties of any kind. We can't promise it will always be available, error-free, or uninterrupted, and we're not liable for any loss arising from your use of it. We may change, pause, or discontinue the game at any time.
Fair use
Play it, share your results, tell your friends — that's what it's for. Please don't try to break, overload, scrape, or reverse-engineer the game, or use it in any way that harms other players or WheyDev LLC. The name, design, and code are ours; the underlying price data belongs to its original public sources.
Your privacy
We collect almost nothing, and never anything that identifies you. The details are in our Privacy page.
Governing law
WheyDev LLC is registered in Wyoming, USA, and these terms are governed by its laws.
Changes and contact
We may update these terms as the game grows; the “last updated” date above always reflects the current version. Questions? Email us at [email protected].
