Privacy Policy

Last updated: March 24, 2026

The Blue application (hereinafter referred to as "we", "our" or "the application") is dedicated to aquarium keeping — both reef (saltwater) and freshwater — and building a passionate community. Protecting your privacy is of paramount importance to us. This privacy policy aims to explain what data we collect, why we collect it, and how we use it.

1. Data Collected

We collect the following data:

  • First and last name
  • Postal address (optional)
  • Phone number (optional)
  • Email address
  • Username
  • User-entered measurements
  • Aquarium data
  • Equipment data

2. Purpose of Data Collection

We collect this data in order to:

  • Personalize the user experience within the Blue community.
  • Provide accurate water parameter measurements.
  • Optimize the experience within the Blue application.

3. Data Collection

User data is collected via a form during registration.

4. Data Storage and Security

User data is stored on a secure server external to the application.

Inactive user accounts without activity for more than 24 months may be subject to deletion after prior notification by email.

5. Cookies and Similar Technologies

As a mobile application, Blue uses local storage and analytics tools to improve the user experience. We do not use traditional browser cookies.

6. Data Sharing

Data sharing concerns information related to the aquarium, measurements, fish, corals, invertebrates, and equipment. Only the user's first and last name are displayed on the sharing page. Sharing is initiated by the user via the share button located on various pages of the application. A sharing opt-out option is available in the "Tank" section when selecting an aquarium. Blue does not share users' personal information.

7. Your Rights (GDPR)

In accordance with the General Data Protection Regulation (GDPR) and applicable data protection laws, you have the following rights regarding your personal data:

  • Right of access: You can request a copy of your personal data at any time.

  • Right of erasure: You can delete your account from the Profile section in the app. Data is removed within 30 days.
  • Right to data portability: You can request your data in a structured, commonly used format.
  • Right to object: You can object to the processing of your data for specific purposes.
  • Right to withdraw consent: You can withdraw your consent at any time without affecting the lawfulness of processing before withdrawal.
