These Terms of Use govern your access to and use of this application. By using the service, you agree to use it lawfully and responsibly and to comply with these terms.

Accounts and access

Some features may be available anonymously, while others require you to sign in using a supported identity provider. You are responsible for activity that occurs through your account and for maintaining control of your sign-in method and associated email account.

Acceptable use

Do not attempt to disrupt the service, interfere with other users, abuse system resources, scrape or exfiltrate data you are not authorized to access, bypass usage limits, or use the service for unlawful, fraudulent, or harmful purposes.

AI-generated content

The service may present AI-generated questions, explanations, translations, and related educational content. This content may be incomplete, inaccurate, or unsuitable for your specific use case. The service is provided for learning and practice purposes only and should not be treated as professional, legal, medical, financial, safety-critical, or official examination advice.

Plans, limits, and features

We may offer different levels of access, including anonymous, free, and Pro experiences. Limits such as daily usage quotas, anonymous session restrictions, available features, supported subjects, and question availability may vary by plan and may change over time.

Subscriptions and billing

Pro subscriptions are processed through the payment provider shown at checkout. Pricing, billing interval, taxes, renewal terms, and included features are presented during checkout and may change for future purchases or renewals.

Unless you cancel, paid subscriptions may renew automatically for the next billing period. If you cancel, Pro access remains active until the end of the current paid billing period, and renewal stops after that. Unless otherwise required by applicable law, purchases and subscription charges are generally non-refundable.

Availability and changes

The service is provided as-is and may change over time. We may add, remove, suspend, or modify features, plans, quotas, integrations, and supported content at any time.

Suspension and termination

We may suspend, restrict, or terminate access when reasonably necessary to protect system integrity, prevent abuse, address security or billing issues, enforce these terms, or comply with legal requirements.
