Guest Access: You may use the App without an account.

To access premium features, or to keep your progress safe across devices, you will need to create an account.

Registered Accounts: You must provide accurate information. You are responsible for keeping your credentials secure and for all activity under your account. If you create an account after using Guest Access, your existing guest progress may be carried over to your new account.

Accounts for Children: If you are under 13, a parent or guardian must read and agree to these Terms and our Privacy Policy on your behalf before the App is used. By tapping "I Agree" on the consent screen, the parent or guardian confirms their consent.

We make every effort to ensure questions and explanations are accurate, but do not warrant that all content is error-free. If you believe a question or answer is incorrect, please contact us at admin@psle-ace.com.

We do not guarantee the App will be available at all times, and may suspend, modify, or discontinue it at any time without notice.
