Terms of Service

1. What the Service is — and is not

The Service is a software tool that processes PDF documents you upload and produces interactive lessons, quizzes, glossaries, diagrams and summaries using artificial-intelligence (“AI”) models. We provide the tool only. We are not the author, publisher, licensor or owner of your documents or of the content generated from them, and we do not endorse, verify or take responsibility for it.

The Service is a study and productivity aid. It is not an educational institution, a tutoring service, a publisher, and it does not provide legal, medical, financial, investment, engineering, safety, or any other professional advice.

2. Accounts

You must provide accurate registration information (or log in through a supported provider), keep your credentials secure, and be at least 13 years old — or the minimum digital-consent age where you live. You are responsible for all activity under your account and must notify us promptly at [email protected] if you suspect unauthorized use.

3. Your content and the output — ownership

You keep everything you bring and everything you make. As between you and us, you retain all right, title and interest in and to (a) the documents and files you upload (“Input”) and (b) the lessons, quizzes, glossaries, diagrams and other material generated for you from that Input (“Output”). We claim no ownership of your Input or Output, and nothing in these Terms assigns or transfers any of your rights to us.

Limited licence to us. You grant us a non-exclusive, worldwide, royalty-free licence to host, copy, process, transmit, display and technically modify your Input solely to operate and provide the Service to you — for example extracting text, sending page excerpts to our AI provider, storing generated Output, tracking your progress, showing your content back to you, and providing support. We may also retain aggregated, de-identified usage data (for example counts of generations) that cannot reasonably be used to identify you or reconstruct your content.

Output is not exclusive. AI systems generate content probabilistically: similar or substantially similar output may be produced for other users, and Output may contain material similar to third-party content. You are solely responsible for ensuring your use of Output does not infringe anyone’s rights.

Your responsibility for the content. You are solely responsible for your Input and for your use of the Output, including for obtaining any third-party permissions, licences or consents needed to upload and process the Input. You must not upload material you do not have the right to use, or material you owe confidentiality duties to (for example an employer’s internal documents, another person’s unpublished work, or records containing personal or sensitive data) unless you are authorised to do so and are permitted to share it with a third-party processor.

Backups. You should keep your own copies of anything you upload. We may delete content in accordance with these Terms, and we are not obliged to retain or restore it.

4. AI-generated content — no warranty of accuracy

Output is generated by AI models and may be inaccurate, incomplete, misleading, biased, or may misinterpret your document. It may also omit or invent facts, figures, formulas, citations or page references. Always verify Output against the original document and against authoritative sources before relying on it.

You agree that: (a) Output is not a substitute for professional advice or for the source material; (b) you will not use Output where accuracy is critical or where an error could cause harm — including medical, legal, financial, safety-critical, engineering or compliance decisions — without independent verification by a qualified professional; and (c) we are not responsible for any decision, action, result, loss, damage, examination outcome or missed opportunity arising from your use of, or reliance on, Output.

5. Third-party AI and infrastructure providers

To generate Output, extracts of your Input are transmitted to third-party AI providers (currently OpenAI) and processed on their systems. We also use third-party hosting, email and payment providers. Those providers act under their own terms and policies; we do not control them and are not liable for their acts, omissions, outages, or changes in their models, pricing or policies.

6. Acceptable use

You agree not to:

• upload content you are not entitled to use, share or process;
• use the Service to create, store or distribute unlawful, defamatory, obscene, hateful, or infringing material;
• upload malware, or attempt to breach or probe the security, authentication or rate limits of the Service;
• access or attempt to access other users’ accounts or data, or scrape or harvest content;
• reverse engineer, resell, sublicense, or provide the Service to third parties without our written permission;
• circumvent credit limits, the generation queue, or any usage control, or use automated means to abuse free or demo allowances;
• use the Service in a way that violates applicable law, export controls, or the rights of others.

We have no obligation to monitor content, but we may review, remove or refuse to process content, and suspend or terminate accounts, where we believe it is necessary to comply with law, enforce these Terms, or protect the Service, other users or third parties.

7. Notices and takedown (copyright and other rights)

If you believe material on the Service infringes your rights, send a notice to [email protected] with: (a) your contact details; (b) identification of the work or right claimed; (c) the location of the material in question; (d) a statement that you have a good-faith belief the use is not authorised; and (e) a statement, under penalty of perjury where applicable, that the information is accurate and you are authorised to act. We may remove or disable the material and, where appropriate, notify the account holder.

8. Credits, subscriptions and billing

• Credits are AI budget, not a unit of content. One credit represents $0.01 of maximum provider AI spend. A job reserves a worst-case amount which is reconciled against the actual provider cost, and any unused reservation is returned to your balance.
• Free accounts receive a one-time starter credit allowance that does not renew. Pro accounts receive a monthly allowance that renews each billing month; unused credits do not roll over and have no cash value.
• Subscriptions are billed by our payment provider (Lemon Squeezy), which acts as merchant of record and handles taxes, invoicing and refunds. Subscriptions renew until cancelled. Cancelling keeps Pro access until the end of the paid period, after which the account reverts to Free.
• Prices may change; changes apply from the next renewal and will be shown before purchase.

9. Availability and changes to the Service

We may add, change or remove features, change models or providers, and impose or adjust usage limits. We do not guarantee uninterrupted operation, and generation jobs may be queued, delayed, paused or fail.

10. Disclaimer of warranties

The Service is provided “as is” and “as available”, without warranty of any kind. To the maximum extent permitted by law, we disclaim all express, implied and statutory warranties, including merchantability, fitness for a particular purpose, title, non-infringement, accuracy, reliability and availability. We do not warrant that the Service will be uninterrupted, secure, error-free, or that Output will be accurate or fit for your purpose.

11. Limitation of liability

To the maximum extent permitted by applicable law:

• we are not liable for any indirect, incidental, special, punitive or consequential damages, or for loss of profits, revenue, data, goodwill, study time, or anticipated savings, however caused;
• we are not liable for the content, accuracy or consequences of Output, or for any decision taken in reliance on it;
• we are not liable for loss, corruption or deletion of your Input or Output, for service interruptions, or for the acts or omissions of third-party providers (including our AI, hosting, email and payment providers);
• our total aggregate liability arising out of or relating to the Service is limited to the greater of (a) the amounts you paid us for the Service in the 12 months before the event giving rise to the claim, or (b) USD 20;

Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for fraud, or for death or personal injury caused by negligence, or any statutory rights you have as a consumer that cannot be waived. Some jurisdictions do not allow certain exclusions, in which case they apply to you only to the extent permitted.

12. Your indemnity

You agree to indemnify, defend and hold harmless PDF Course and its owners, employees and providers from and against any claim, demand, loss, liability, damage, cost or expense (including reasonable legal fees) arising out of or relating to: your Input; your use of Output; your breach of these Terms; or your violation of any law or third-party right.

13. Termination

You may delete your account and its content at any time in your account settings; deletion removes your profile and associated content, except records we must keep for billing, security or legal reasons. We may suspend or terminate your access for breach of these Terms, for non-payment, or where required by law. Sections 1, 3, 4, 10, 11, 12, 13 and 14 survive termination.

14. General

• Changes to these Terms. We may update these Terms; material changes will be announced in the app or by email and take effect from the stated date. Continued use means you accept them.
• Governing law and disputes. These Terms are governed by the law of the country in which the operator of the Service is established, without affecting any mandatory consumer rights — including the right to sue in your country of residence — that apply to you.
• Entire agreement, severability, no waiver. These Terms and the Privacy Policy are the entire agreement between us. If a provision is unenforceable, the rest remains in force. A failure to enforce a provision is not a waiver of it.
• Assignment. You may not assign these Terms without our consent; we may assign them to a successor or in connection with a reorganisation or sale.
