A PEACEFUL PLACE, CLEAR TERMS
Terms of use
Effective November 6, 2026
Provider and agreement
Duo Aquarium: Calm Fish Tank is provided by GGAP LLC, with Herb Trevathan as the contact. These terms describe use of the app and its product website. For the iOS app, Apple's Standard Licensed Application End User License Agreement also applies. These terms supplement that agreement and do not replace its mandatory provisions or your statutory rights.
Your aquarium
Subject to the applicable license, you may use the app on compatible Apple devices you own or control as permitted by Apple's usage rules. The app is a virtual aquarium for entertainment and relaxation. Fish, plants, water conditions, and care actions are simulated. It is not medical treatment, a promise of a health outcome, or guidance for caring for real animals.
One-time purchase
The App Store displays the final purchase price, currency, and applicable taxes before you buy. The current app has no subscriptions, advertisements, consumable purchases, or paid food. Your purchase provides access to the features included in the purchased app version; it is not a promise of every future product, unlimited maintenance, or perpetual compatibility. Purchases, redownloads, Family Sharing eligibility, cancellations where available, and refund requests are handled through Apple under its terms and applicable law.
Local data and sharing
Your aquarium and saved arrangements are stored on your device. You are responsible for any device backups you wish to keep. Resetting the aquarium or deleting the app may remove your setup. If you share an aquarium image, you choose the recipient or service and are responsible for that sharing. Our Privacy policy explains these features.
Respectful and lawful use
Do not use the app or website unlawfully, interfere with their security, redistribute the app or artwork as your own product, or infringe others' rights. Restrictions on copying, modification, and reverse engineering apply only to the extent permitted by applicable law and Apple's license. You may share ordinary aquarium snapshots made using the app for personal or social use.
Ownership
GGAP LLC and its licensors retain rights in the software, branding, and bundled content. Your purchase is a license to use the app, not a transfer of those rights. Apple, iPhone, and iPad are trademarks of Apple Inc. Duo Aquarium is an independent app and is not sponsored or endorsed by Apple.
Availability and updates
Features depend on device capabilities and operating-system support. We may provide updates to improve, repair, or change the app. Compatibility and continuous availability are not guaranteed. We do not guarantee App Store approval or a particular release date. Device-specific layout behavior may differ; see the current App Store listing for supported systems.
Warranties, liability, and consumer rights
To the extent permitted by law, the app and website are supplied as available without additional warranties beyond those required by law or Apple's applicable license. Nothing here excludes mandatory consumer guarantees, liability that cannot legally be excluded, or remedies available under applicable law. Apple's standard license governs applicable warranty and liability provisions for the iOS app. Stop using the app if its motion or lighting feels uncomfortable; reduce motion and brightness are available.
Support, changes, and contact
Contact GGAP LLC / Herb Trevathan at herb.trevathan@icloud.com for support or questions. We may update these terms and their effective date. Changes will apply subject to applicable law and any notice or consent required by law; they do not remove rights you already have.
