FAQ
Where does the data come from?
Steam's public review summary (IUserReviewsService/GetAppReviews). We store only per-language totals, cached for up to 12 hours.
Is this affiliated with Valve or Steam?
No. Fizz Labs is independent and not affiliated with Valve. Steam is a trademark of Valve Corporation.
Why does my game show "low sample"?
A language with fewer than 200 reviews can swing a lot from a handful of reviews, so we mark it instead of warning.
Why did I get a "try again later" message?
Steam limits how often its public API can be called. If we have no cached copy yet, please retry in a few minutes.
Do you collect my email or use cookies?
No. We count anonymous button clicks only. Quotes go through your own email client to support@fizzlabs.ai.
What's the weekly digest?
A planned paid product (from $29/mo, estimate) that summarizes Chinese, Japanese and Korean negative-review themes for your game each week. Click "Notify me" to tell us you want it — we build it only if enough studios ask.
Can you fix my store page localization?
Yes — see our store listing localization service, store-l10n (fizz-store-l10n.pages.dev).
