Common questions
Do I need an account?
No. The current quiz version keeps progress locally without a YSFMARK account.
Why do I see ads?
Ads support the app. Advertising options and personalisation depend on consent, your region, and device settings. See the app’s Privacy options where available.
Can I change my advertising choice?
Open Privacy options inside the app where that entry is available. You can also manage advertising identifiers in Android’s privacy settings.
How do I report a question?
Send the question wording or a screenshot that does not reveal personal information, explain the issue, and include the app version. We review corrections without promising an immediate update.
Contact us
Let’s work it out.
Include the app name, app version, device model, and what happened. Never send passwords, payment-card details, identity documents, or private cooking notes.
