Privacy Policy

Effective date: 2025-11-27 · Last updated: June 2026

This privacy policy applies to the Wachty app (hereby referred to as "Application") for mobile devices, created by Mateusz Moc.

1. Locally Stored Data

The Application stores voyage data (names, dates, crew details, phone numbers, logbook entries) exclusively on the user's device. This data is not automatically transmitted to any server and is not accessible to the developer.

2. Location Data (GPS)

The Application requests location access for two purposes:

• Voyage Logbook — coordinates, speed, and course are stored locally when a watch change is recorded or a manual log entry is made.
• Weather Service — when the weather service is enabled, current GPS coordinates are sent to Open-Meteo (open-meteo.com) to retrieve a local weather forecast. No user-identifying data is transmitted.

Location access is optional — the app works without it, but logbook and weather features will be unavailable. The app does not track location in the background.

3. Third-Party Services

Firebase Analytics and Crashlytics (Google LLC)

The Application uses Firebase Analytics and Firebase Crashlytics by Google. These services collect anonymous usage data (number of sessions, screens viewed, in-app events) and crash reports. Data is not linked to the user's identity — no login, email address, or name is involved.

Data is processed by Google LLC in accordance with their privacy policy: policies.google.com/privacy

Open-Meteo (open-meteo.com)

When the weather service is enabled (default: on), the Application sends GPS coordinates to the open-source weather API Open-Meteo to retrieve a local forecast. Open-Meteo requires no account or login. Open-Meteo privacy policy: open-meteo.com/en/terms

The weather service can be disabled in the app's Settings — when disabled, no data is sent to Open-Meteo.

4. iCloud Backup

The Application offers an optional backup of voyages to a user-selected folder in iCloud Drive. Backup is triggered manually by the user only. Data is stored on the user's own iCloud account and is not accessible to the developer.

5. Permissions

The Application may request the following permissions:

• Location: voyage logbook and weather service. Optional.
• Notifications: local watch change reminders. Optional.
• Camera: scanning a QR code with voyage settings. Optional.

6. Data Sharing

Voyage data is not shared with third parties. It leaves the device only through explicit user actions:

• Generating a PDF file with the crew list or schedule.
• Sending a voyage file (.wachty) via AirDrop or a messaging app.

7. Security

Voyage data is stored locally on the device. PRO status (in-app purchase) is stored in the iOS Keychain.
