Terms of Service
Last updated: 21 October 2026
These terms cover your use of Good Eye, a tool made by Kinoko Studio that uses AI to predict visual attention. By using Good Eye, you agree to them.
Who we are
Good Eye is run by Kinoko Studio in Hong Kong and is available at goodeye.kinokostudio.com.hk. In these terms, "we", "us" and "our" mean Kinoko Studio.
Your account
Good Eye uses Google Sign-In, and the iPhone app also offers Sign in with Apple, so you need a Google account, or an Apple account on iPhone, to use anything beyond the sign-in screen. You're responsible for keeping your account secure and for all activity under it. Each person may have one account.
Credits
Good Eye runs on credits, and each analysis costs one credit. New accounts get a one-time bonus of 15 free credits the first time they sign in. You can also buy credit packs at any time. Neither the welcome credits nor paid credits expire, and paid credits carry over indefinitely.
The apps and the website share one credit balance. Credits you buy in an app and credits you buy on the website are the same credits, and they don't expire. If you delete your account, your credits are deleted with it, as described in our Privacy Policy.
All credit purchases are final, except that refunds for in-app purchases go through Apple or Google (see Payments). We don't refund credit packs once you've bought them, except where the law requires it. Credits have no monetary value and can't be transferred or exchanged for cash.
Payments
On the website, Stripe processes our payments, so when you buy credits there you also agree to Stripe's terms. We don't store your card details. We keep purchase records for accounting, as described in our Privacy Policy.
In the iPhone and Android apps, you buy the same credit packs through the App Store or Google Play. The store takes the payment, and its terms also apply to the purchase. Refunds for in-app purchases go through Apple or Google under their terms, not through us.
Acceptable use
You agree not to use Good Eye to:
- upload images that are illegal, infringing or defamatory, or that violate anyone else's rights, including any image that depicts minors in a sexual manner;
- reverse-engineer, scrape or extract the underlying models or technology;
- send automated requests in a way that abuses the service or interferes with other users;
- get around or manipulate the credit system.
We may suspend or close accounts that break these terms.
Your images and content
You own the images you upload. When you upload an image, you confirm that you have the right to use it, and you give us a limited licence to process it and store the result in your private analysis history, as described in our Privacy Policy. We don't claim ownership of your images, and we use them only to provide the service to you.
Results are predictions
Good Eye gives you AI-generated predictions of visual attention. They're statistical estimates from machine-learning models, and they don't replace laboratory eye-tracking studies or research with real people. We don't guarantee that any result is accurate for a particular image or audience.
Intellectual property
Good Eye, its attention models, and all related technology and content are proprietary to Kinoko Studio. Nothing in these terms grants you any licence to Kinoko Studio's intellectual property beyond the right to use the service as intended.
Disclaimer of warranties
Good Eye is provided "as is" and "as available" without warranties of any kind, express or implied. We do not warrant that the service will be uninterrupted, error-free, or that results will be accurate for your purposes.
Limitation of liability
To the fullest extent permitted by law, Kinoko Studio is not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of Good Eye. Our total liability for any claim arising from these terms or your use of the service is limited to the amount you paid us in the 12 months before the claim.
Changes to these terms
We may update these terms from time to time. When we do, we'll change the "Last updated" date above, and if a change is material, we'll let you know the next time you sign in. If you keep using Good Eye after an update, you accept the revised terms.
Governing law
These terms are governed by the laws of Hong Kong SAR. Any disputes shall be subject to the exclusive jurisdiction of the courts of Hong Kong.
