The app may store certain app-related data locally on your device. This may include selected species, favorite items, filter settings, language preferences, recently viewed sections, or other preferences needed to make the app work correctly.
When the app or website version loads content from our server, standard technical information may be processed automatically by hosting systems. This may include your IP address, device type, browser or WebView information, operating system, requested pages or files, date and time of access, and technical logs.
This technical information is used for security, maintenance, troubleshooting, performance monitoring, and keeping the app available. We do not use this information to directly identify individual users.

We use information handled by the app to provide and maintain the core functionality of Aquarium: Compatibility and Calculator.
This includes displaying aquarium species data, checking selected combinations, saving favorites locally, loading images and content, remembering app preferences, improving app stability, and helping the interface work correctly on different devices.
Technical logs may be used to diagnose errors, prevent misuse, protect the service, monitor server performance, and improve reliability.
We do not sell personal information. We do not rent or trade personal information. We do not require users to submit sensitive personal information to use the main features of the app.
Local Storage
Aquarium: Compatibility and Calculator may use local storage, device storage, browser storage, or WebView storage to remember user preferences and app state.
For example, the app may save favorite species, selected filters, language settings, or other interface preferences. This information is stored on your device and is used only to improve your experience inside the app.
You can remove locally stored data by clearing the app data in your device settings, clearing browser or WebView storage, or uninstalling the app.
Internet Access
The app may use internet access to load certain content, images, updates, website resources, or app data from our server.
When internet access is used, standard technical information may be processed by servers, hosting providers, or infrastructure services. This processing is limited to what is needed for app delivery, maintenance, and security.
Third-Party Services
The app may rely on technical infrastructure such as hosting providers, platform services, or server systems that help deliver app content and keep the service available.
These services may process standard technical information such as IP address, device information, request logs, and performance data as part of normal server operation.
If future versions of the app include analytics, advertising, crash reporting, or other third-party SDKs, this Privacy Policy may be updated to explain what services are used and what information may be processed.
Cookies and Similar Technologies
The website version of Aquarium: Compatibility and Calculator may use cookies, local storage, browser storage, or similar technologies to support functionality and remember preferences.
These technologies may be used to store favorites, filters, selected settings, or other app states. They may also be used by hosting or technical services for security, performance, and maintenance.
Data Sharing
We do not sell, rent, or trade personal information.
Technical information may be processed by service providers that help host, operate, secure, or maintain the app and website. These providers process information only as needed to provide their services.
We may disclose information if required by law, legal process, government request, or if necessary to protect the rights, safety, security, or integrity of the app, users, or others.
Data Retention
Local app data, such as favorites or settings, may remain on your device until you delete it, clear app storage, or uninstall the app.
Server logs and technical records may be retained for a limited period as needed for security, troubleshooting, maintenance, and legal compliance. Retention periods may vary depending on hosting provider settings and operational needs.
Children’s Privacy
Aquarium: Compatibility and Calculator is an educational aquarium planning tool. It is not designed to knowingly collect personal information from children.

Educational Disclaimer
The information provided by Aquarium: Compatibility and Calculator is for educational and planning purposes only.
Aquarium species behavior may vary depending on tank size, water parameters, age, sex ratio, individual temperament, feeding, layout, hiding places, water quality, and other conditions.
The app does not replace advice from experienced aquarists, veterinarians, aquatic specialists, or other qualified professionals. Users should always observe living creatures carefully and make responsible care decisions.
Security
We take reasonable steps to protect the app and related services from unauthorized access, misuse, data loss, and technical issues.
However, no method of internet transmission or electronic storage is completely secure. Because the app does not require users to submit sensitive personal information, the privacy risk is limited compared with services that collect accounts, payments, or personal profiles.
