3. Mode and place of processing the data

Methods of processing

The controller processes personal data in a proper manner and takes appropriate security measures to prevent unauthorized access, disclosure, modification, or unauthorized destruction of data.

Data processing is carried out using computers or IT-based systems, following organizational procedures specifically tailored to the stated purposes.

Place

Data is processed at the controller's operating offices and in any other place where the parties involved in the processing are located. Depending on the user's location, data transfers may involve transferring the user's data to a country other than their own.

Retention time

Unless specified otherwise in this document, personal data is processed and stored for as long as required by the purpose it has been collected for.

4. The purposes of processing

Personal data about the user is collected to allow the controller to provide its service and comply with its legal obligations. In addition, data is collected for the following purposes:

  • Handling of activity data
  • Management of productivity operations
  • Platform services and hosting
  • Location-based interactions
  • Photo and media management
  • Authentication via third-party providers

5. Detailed information on the processing of personal data

Handling of activity data

This type of service allows the controller to use activity data for this app to perform or provide certain features (e.g. recording fishing sessions as a workout).

Apple HealthKit — Apple Inc., United States
Data processed: general activity data

Platform services and hosting

These services have the purpose of hosting and running key components of this app, thus allowing it to be provided through a unified platform, including the handling of payments for in-app subscriptions.

App Store Connect — Apple Inc., United States
Data processed: device information, purchase data (for in-app subscriptions)

Location-based interactions

Geolocation
Data processed: geographic position

This app continuously collects the user's location (GPS) during active fishing trips to record the route covered and display it on a map. Location tracking can be revoked by the user at any time via the device settings.

Management of productivity operations

Apple iCloud — Apple Inc., United States
Data processed: device information, trip and catch data, photos

This app uses Apple CloudKit to store the user's data (trips, catches, photos) in their private iCloud database and to sync it across the user's devices. The provider itself has no access to this data.

Access to camera and photo library

This app accesses the device's camera and/or photo library to allow users to take photos of their catches, or select them from the photo library, and save them within the app.

Data processed: photos, images
Place of processing: user's device / user's private iCloud database (Apple Inc.)

These photos are stored exclusively alongside the other trip data via the user's private iCloud environment and are not transmitted to the provider or any other third party.

Sign in with Apple

This app allows users to register and log in via "Sign in with Apple." In doing so, Apple Inc. processes the user's login data as an independent controller (e.g. an Apple-generated, pseudonymous user identifier as well as, if shared by the user, their name and email address).

Provider: Apple Inc., United States
Data processed: user identifier, possibly name and email address

6. Cookies and trackers

This app uses no cookies and no tracking technologies for advertising or analytics purposes. No ad tracking takes place and no advertising IDs (e.g. IDFA) are processed.

The third-party services mentioned in this privacy policy (Apple HealthKit, Apple iCloud, App Store Connect, Sign in with Apple, Geolocation) serve exclusively to provide the app's core features and not to track user behavior.
