Terms of Service
Effective 5 July 2026. This is a binding agreement between you and Junius Lau (operating as ZeniStudy) (“ZeniStudy”, “we”, “us”), governing your use of the ZeniStudy website, app, and API (the “Service”).
1Acceptance of these Terms
By creating an account, or by using the Service in any way, you agree to these Terms and to our Privacy Policy. If you don’t agree, don’t use the Service. If you’re using ZeniStudy on behalf of a school, company, or other organization, you’re confirming you have authority to bind that organization to these Terms.
2Eligibility & capacity to contract
You must be at least 13 years old to use ZeniStudy. Malaysian law generally treats anyone under 18 as a minor who cannot be bound by a contract on their own (Age of Majority Act 1971), so:
- If you’re 13–17, you may use free features, but a parent or legal guardian must make (or directly authorize) any purchase — credits, a subscription, or extra Library slots — and that parent or guardian is the one agreeing to Sections 7 and 14 of these Terms and is responsible for the charges.
- If you’re 18 or older, you’re contracting on your own behalf.
We don’t knowingly let anyone under 13 create an account. See Section 10 of the Privacy Policy for what happens if we learn otherwise.
3What the Service is
ZeniStudy lets you upload study material (documents, text, or a lecture/video transcript) and generates study guides, flashcards, and quizzes from it using an automated AI model, subject to a credit-based usage system. Some outputs are automatically kept in your Library so you can revisit them without regenerating; quizzes you complete can be saved with your results.
4Your account
You need an account to use most of the Service. You’re responsible for keeping your login credentials confidential and for everything that happens under your account. Tell us immediately at juniustk905@gmail.com if you suspect unauthorized access. One account per person — don’t share credentials or create accounts to get around a limit, a suspension, or the free-signup credit grant.
5AI-generated content — read this
The most important section in this document
Study guides, flashcards, and quizzes are produced by an automated third-party AI model based on what you upload. They can be wrong.
- Generated content may contain errors, outdated information, omissions, or entirely fabricated (“hallucinated”) facts, citations, or figures.
- It is not a substitutefor your actual course materials, textbook, syllabus, or instructor — it’s a study aid, not an authoritative source.
- We do not guarantee accuracy, completeness, or that using ZeniStudy will improve your grades, test scores, or any academic outcome.
- You’re responsible for checking anything you intend to rely on academically against your own source material before you trust it.
- You’re also responsible for following your own school’s or institution’s rules on AI use and academic integrity — ZeniStudy is a tool; how you use its output against your institution’s policies is on you, not us.
6Your content & our license to it
You keep ownership of whatever you upload. By uploading it, you give us a limited, non-exclusive license to store, process, transmit (including to the third-party AI and OCR providers listed in Section 11), and display it back to you, solely to operate the Service and generate your requested output.
You confirm that you have the right to upload whatever you upload, and that doing so doesn’t infringe anyone else’s copyright, privacy, or other rights — for example, you shouldn’t upload someone else’s personal or confidential information without their permission, or material you don’t have the right to reproduce or process this way. You’re responsible for your uploads; see Section 15 (Indemnity).
7Credits, payments & subscriptions
Credits are a prepaid license to use AI-generation features. They are not currency, have no cash value, aren’t transferable between accounts, and can’t be redeemed for cash.
Prices are shown and charged in USD, processed by Stripe. Subscriptions renew automatically at the end of each billing period until you cancel; cancelling stops the next renewal — you keep access through the period you already paid for. One-time top-ups, credit packs, and the Library-slots purchase are single charges with no renewal.
All sales are final.Credits, top-ups, subscription payments, and Library-slot purchases are non-refundable except where a refund is required by applicable law (see the Refund & Billing Policy, Section 3, for the full policy and how chargebacks are handled).
8Saved content & storage limits
Your Library has a limit on how many study guides, flashcard decks, and saved quizzes you can keep at once; you can raise that limit with a one-time purchase, or free up space by deleting items. We don’t promise unlimited or permanent storage — if you delete your account, or if we terminate it under Section 12, saved content is removed along with it.
9Acceptable use
Don’t do any of the following:
- Upload unlawful, infringing, or malicious content (including malware).
- Reverse-engineer, scrape, or attempt to circumvent the Service’s rate limits, credit system, or security controls.
- Resell, sublicense, or provide bulk/automated access to the Service without our written permission.
- Use the Service to generate content for someone else’s benefit at commercial scale outside your own personal study use, without our permission.
- Interfere with the Service’s operation or other users’ use of it.
We can suspend or terminate accounts that break this section — see Section 12.
10Our intellectual property
The Service — its software, design, and the ZeniStudy name and logo — belongs to Junius Lau (operating as ZeniStudy) or our licensors. These Terms don’t give you any rights to our IP beyond what’s needed to use the Service as intended.
11Third-party services
ZeniStudy relies on third-party providers to work:
| Provider | What it’s used for |
|---|---|
| Stripe | Payment processing. Stripe handles your card details directly — we never see or store full card numbers. |
| Supabase | Account authentication and some data storage. |
| DeepSeek | The AI model that generates study guides, flashcards, and quizzes from your uploaded content. |
| Google Cloud Vision | Optical character recognition (OCR) for scanned/image-only PDFs. |
| Vercel | Application hosting and infrastructure. |
We’re not liable for outages, errors, or failures caused by these third-party providers that are outside our reasonable control.
12Suspension & termination
You can delete your account at any time from Settings. We can suspend or terminate your account, immediately and without refund, if you breach these Terms, we reasonably suspect fraud or abuse, you file a payment chargeback instead of contacting us first, or we’re required to by law. Sections 5, 6 (as to content already processed), 13, 14, 15, and 16 survive termination.
13Disclaimer of warranties
The Service is provided “as is” and “as available.”To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We don’t warrant the Service will be uninterrupted, error-free, or that generated content will be accurate (see Section 5).
14Limitation of liability
To the fullest extent the law allows, ZeniStudy and its officers, employees, and contractors are not liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, goodwill, or academic outcomes (including exam results, grades, or admissions decisions), arising from your use of the Service.
Our total liability for any claim relating to the Service is capped at the greater of USD 100or the amount you actually paid us in the 12 months before the claim arose. This cap doesn’t apply where the law doesn’t allow it (for example, liability for fraud or for death or personal injury caused by negligence, to the extent Malaysian law makes such a cap unenforceable).
15Indemnity
You agree to indemnify and hold us harmless from any claim, loss, or expense (including reasonable legal fees) arising from your breach of these Terms, your uploaded content, or your misuse of the Service.
16Governing law & disputes
These Terms are governed by the laws of Malaysia, without regard to conflict-of-law rules.
Arbitration. Any dispute arising from these Terms or the Service — other than a claim that qualifies for small-claims court, or a request for urgent injunctive relief — will be resolved by binding arbitration administered by the Asian International Arbitration Centre (AIAC) under its Arbitration Rules (or its Fast Track Rules, where the amount in dispute qualifies), seated in Kuala Lumpur, conducted in English, before a single arbitrator.
Individual claims only.Disputes will be arbitrated on an individual basis only. Neither you nor we may bring a claim as a class, collective, or representative action, or consolidate an arbitration with anyone else’s, to the fullest extent the law allows.
17Changes to these Terms
We may update these Terms from time to time. We’ll post the revised version here with a new effective date and, for material changes, tell you by email or in-app notice. Continuing to use the Service after a change takes effect means you accept it.
18General
If any part of these Terms is found unenforceable, the rest remains in effect. Our failure to enforce a right isn’t a waiver of it. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Neither party is liable for delay or failure caused by events outside its reasonable control. These Terms, together with the Privacy Policy and Refund & Billing Policy, are the entire agreement between us. Notices to us go to juniustk905@gmail.com.
