By accessing or using XTREME ZOOM (the "Service") at xtremezoom.com, you agree to be bound by these Terms of Service and the Privacy Policy. If you do not agree, please do not use the Service.
XTREME ZOOM is a browser-based visual guessing game in which players identify mystery objects from extreme close-up images. The Service includes free guest play, optional accounts, leaderboards, daily challenges, and optional paid upgrades.
You must be at least 13 years old (or the minimum age required in your country) to use XTREME ZOOM. By using the Service you represent that you meet this requirement. Minors should use the Service only with the consent and supervision of a parent or legal guardian.
Some features may require sign-in. You are responsible for keeping your account secure and for all activity that occurs under your account. We may remove leaderboard entries, display names, or accounts that violate these Terms or that we reasonably believe are fraudulent.
Paid upgrades, subscriptions, and virtual items may be offered through external payment providers (such as Stripe). Billing, renewal, and cancellation follow the terms shown at the time of purchase and applicable consumer-protection laws. Virtual items have no real-world monetary value and are non-transferable.
The Service is supported in part by advertising, including ads served by Google AdSense and similar partners. Use of these ad services is governed by their own terms and privacy policies. See the Privacy Policy for details on cookies and personalized advertising.

To the maximum extent permitted by law, XTREME ZOOM and its operators shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, data, goodwill, or other intangible losses arising from or related to your use of the Service.
