Terms of Service

Last updated: 12 November 2026

These terms are an agreement between you and Fuqin Fang ("Sagacia", "we", "us"), the operator of the Sagacia service at sagacia.ai and related sites and apps (the "Service"). By creating an account or using the Service you agree to them.

1. The Service

Sagacia is a study tool for exam preparation. It provides online past papers and practice questions, automated and AI-assisted marking, grade estimates, and explanations. Marking, grade estimates and explanations are produced with the help of AI models. They are study aids and can be wrong. They are not official results and are not a prediction or guarantee of any exam outcome, university offer or predicted grade issued by a school.

2. Accounts

• You sign in with an email address and a one-time code. Keep access to that email secure; you are responsible for activity on your account.
• You must give accurate information when we ask for it, including your real name, school and country. We may suspend accounts that give false information.
• If you are under 18, you may use the Service only with the permission of a parent or legal guardian, who agrees to these terms on your behalf. The Service is not directed to children under 13.
• One account is for one person. Do not share or sell accounts.

3. Subscriptions and payment

• Paid features are sold as monthly subscriptions per subject at the prices shown on the Pricing page. A subscription renews automatically each month until you cancel. If you cancel, you keep access until the end of the period you have paid for.
• We may change prices for future periods. We will tell you at least 14 days before a price change applies to your subscription, and you can cancel before it does.
• Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries about payments and handles returns for payments. Taxes are calculated and collected by Paddle at checkout.
• Subscriptions are personal and cannot be transferred. Refunds are described in the Refund Policy.

4. Acceptable use

• Use the Service for your own study. Do not copy, scrape or bulk-download questions, mark schemes, explanations or other content, and do not use the Service to build a competing product or to train AI models.
• Do not attempt to disrupt the Service, get around usage limits, or access other people's data.
• Do not upload content that is unlawful or that you have no right to upload.

We may limit, suspend or close accounts that break these rules. Explanations may carry visible and invisible marks that identify the account that viewed them.

5. Content and intellectual property

The software, explanations, generated questions and other content of the Service belong to us or our licensors. Past examination questions remain the property of their respective exam boards and are shown for individual study. You keep the rights in the answers and photos you submit and give us permission to process them to provide and improve the Service, including checking and improving marking quality.

6. Availability and changes

We work to keep the Service available but do not promise it will be uninterrupted or error-free. We may change or withdraw features. If we close the Service, we will refund the unused part of any subscription period you have paid for.

7. Liability

The Service is provided "as is". To the extent the law allows, we are not liable for indirect or consequential loss, or for exam results, admissions decisions or other outcomes, and our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have as a consumer that cannot be limited by law.

8. Ending the agreement

You may stop using the Service at any time and ask us to delete your account. We may end or suspend your access if you break these terms.

9. Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region, without affecting mandatory consumer protections of the country where you live.
