Terms of Service

1. Website operator and agreement

This website is operated by Sylva Technology Limited, Business Registration Number 80261442, at Room 1508, 15/F, Office Tower Two, Grand Plaza, 625 Nathan Road, Mong Kok, Hong Kong (the “Operator”, “we”, or “us”). These terms apply when you access this website or use services provided by us.

This website is operated by Sylva Technology Limited. The iOS app is distributed and in-app purchases are processed by the seller and platform identified on its App Store listing.

By using the service, you agree to these terms. If you do not agree, do not use the service.

2. What the service does

Aquascape visualization software that helps people explore aquarium and vivarium design ideas using photos of their own spaces.

Generated images are visual concepts. They are not biological, structural, electrical, engineering, or livestock-safety advice, and they do not guarantee that a pictured design can be built safely or successfully.

3. Accounts and permitted use

You must provide accurate account information, protect your sign-in details, and promptly report suspected unauthorized use. You are responsible for activity carried out through your account.

You may use Vivarium only lawfully and in accordance with the Acceptable Use Policy. We may restrict or suspend access when reasonably necessary to protect users, third parties, or the service.

4. App Store purchases and delivery

Subscriptions and credit packs are currently purchased in the iOS app through Apple’s in-app purchase system. The App Store shows the final price, currency, billing period, and applicable tax before confirmation.

After Apple confirms a purchase, the applicable credits or subscription entitlement are added to the customer account. Generation delivery follows the status shown in the app.

Generation time varies with image complexity, service demand, and provider availability. The app shows job status and makes completed concepts available in the user account.

When a generation job fails, credits reserved for that job are returned automatically. If an automatic return does not appear, contact support for review.

5. Credits and subscriptions

Credits are limited, non-transferable service units used only for Vivarium generation services. They are not money, cannot be withdrawn or transferred between users, and have no cash value.

An App Store subscription renews for the billing period shown at purchase until cancelled through Apple. Cancellation rules appear in the Subscription Cancellation Policy. Refund requests follow the Refund and Dispute Policy.

6. Intellectual property

You keep rights you hold in images you upload. You give us the limited permission needed to host, process, and transform those images to provide and secure the service.

Vivarium, its interface, software, and original materials are owned by us or our licensors. Generated output may be affected by third-party rights and applicable law; we do not promise that every output is exclusive or registrable.

7. Liability and governing law

The service is provided with reasonable care, but AI output can be incomplete, inaccurate, or unsuitable. Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded.

These terms are governed by the laws of the Hong Kong Special Administrative Region, without limiting any mandatory consumer rights that apply in the customer’s place of residence. Disputes will be handled in the non-exclusive jurisdiction of the courts of Hong Kong, subject to mandatory consumer rights.
