YOUR WORLD, YOUR PRIVACY
Privacy policy
Effective November 6, 2026
Who operates the app
Duo Aquarium: Calm Fish Tank is provided by GGAP LLC, with Herb Trevathan as the contact. Email herb.trevathan@icloud.com with privacy questions or requests.
Information in the aquarium app
The app stores your selected fish and plants, habitat, lighting, motion settings, saved aquarium arrangements, feeding time, and simulated glass clarity on your device. Native comfort preferences are also stored on your device. These settings are used to restore your aquarium and operate the simulation. We do not receive or upload them.
The app does not request your contacts, location, camera, microphone, health information, or photo-library access. It does not include third-party advertising or analytics SDKs. It does not track you across apps or websites, and we do not sell or share personal information for advertising.
Offline use and optional sharing
Aquarium artwork, simulation code, sound generation, help, and these legal documents are bundled in the iOS app. Normal aquarium use requires no internet connection. If you choose Share, the app makes an aquarium image available to the destination you select in the system share sheet. That destination handles the image according to its own practices. The app does not independently upload the image or retain a developer copy. Links you choose to open outside the aquarium, including email support or Apple's terms, may use the internet.
Apple services
Apple handles payment and download of the paid app. We do not receive your payment-card details through the app. Apple may process purchase records, diagnostics, device backups, or other information under your Apple settings and Apple's privacy policy. Device backups may include your locally stored aquarium. The app does not implement its own cloud synchronization.
Support correspondence
If you email us, we receive your email address and any information or attachments you choose to send. We use this to answer your request and maintain necessary support, security, or legal records. Do not include passwords or payment details. Support correspondence is retained only as needed for those purposes or applicable legal obligations. Contact us to request access, correction, or deletion; applicable exceptions may apply.
This website
This product website uses no advertising pixels, analytics scripts, or nonessential cookies. Its hosting provider may process standard request information such as IP address, browser details, requested address, and access time to deliver pages and protect the service. Those logs are governed by the host's operational retention settings. Email links open your email app; there is no contact form collecting data here.
Deleting your data
In the app, open Settings and choose Reset aquarium and saved tanks to clear aquarium settings and saved arrangements. Native comfort switches can be changed separately in Settings. Deleting the app removes its local data, subject to device backup behavior controlled by Apple. If you use the browser demo, Reset aquarium clears its saved tanks in that browser; you can also clear the site's browser storage. We have no server copy of your aquarium to delete.
Children and international users
The aquarium does not require an age, profile, or personal information to play. We do not knowingly collect children's personal information through the app. A parent or guardian who believes information was sent to support by a child can contact us for help deleting it. If you send a support message, your email provider and ours may process that correspondence in countries outside your own.
Changes and contact
We will update this page and its effective date when our practices change. Material changes will also be explained in the app or release information as appropriate. Privacy contact: GGAP LLC / Herb Trevathan, herb.trevathan@icloud.com.
