Legal
Terms of Service
The rules for using IsThisAI, including credits, subscriptions, acceptable use and the limits of detection results.
Last updated Oct 25, 2026
1. Who you are dealing with
These terms are between you and Wang Xiaochun, an individual trader operating IsThisAI, High House, High Street, Sai Ying Pun, Hong Kong (support@isthisai.pro). By creating an account or using the service you accept these terms.
2. The service
IsThisAI analyses text and images you submit and returns a report with a detection score, the evidence available and the limits of the result. Content types marked "in evaluation" are not available or sold until they are released.
3. What results mean
Detection is probabilistic. Scores and verdicts are evidence, not proof, and can be wrong in both directions. Do not use a result as the only basis for a decision that affects someone's rights, education, employment, reputation or access to services. We do not guarantee any particular accuracy.
4. Eligibility and accounts
You must be at least 18. Keep access to your email account secure, because sign-in codes are sent there. You are responsible for activity on your account. One person may claim the free sign-up credits once.
5. Credits
- Credits are used to run checks. The cost of each check is shown before you run it.
- Credits have no cash value, cannot be transferred or exchanged, and are not refundable except as set out in our Refund Policy or required by law.
- Free sign-up credits expire after 7 days. Monthly plan credits reset at the start of each billing period and do not roll over. Credit pack credits expire 12 months after purchase.
- Credits are reserved when a check starts and charged only when a usable report is ready. If a check fails, the reserved credits return to your balance.
6. Plans, payment and cancellation
Prices are in US dollars and include VAT or similar taxes where they apply. Monthly plans renew automatically each month on the purchase date until cancelled. You can cancel at any time in your account; the plan stays active until the end of the paid period and is not charged again. We may change prices for future periods; we will tell you before a change affects your renewal, and you can cancel before it applies.
7. Acceptable use
You must not:
- submit content you are not allowed to share, or that is illegal, sexually exploits minors, or infringes others' rights;
- use the service to harass, defame or discriminate against anyone;
- try to break, overload, scrape, reverse engineer or get around the limits or security of the service, including the human check;
- create multiple accounts to collect free credits.
We may suspend or close accounts that break these rules.
8. Your content
You keep all rights in the content you submit. You give us a limited licence to store and process it, and to send it to our detection provider, only to run your checks and show your reports. We do not use your content to train AI models. Retention is described in our Data Retention page.
If you believe content on IsThisAI infringes your copyright, email support@isthisai.pro with the details.
9. Availability and changes
We work to keep the service available but do not promise it will be uninterrupted. Detection engines and their versions may change; each report records the engine and version used.
10. Liability
To the extent the law allows, the service is provided "as is", and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.
11. Ending the agreement
You can stop using the service and delete your account at any time. We may end these terms if you seriously breach them. Sections that by their nature should survive (such as liability and governing law) continue after the end.
12. Law and disputes
These terms are governed by the laws of the Hong Kong Special Administrative Region. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live and may bring proceedings there.
13. Changes to these terms
We will post changes here and update the date above. For material changes we will tell signed-in users in advance.
