Privacy Policy — Kubu

Last updated: 2026-05-28

1. Introduction

Kubu is an iOS mobile application for managing group holiday budgets. It is developed and published by an independent developer.

2. Data collected

Kubu does not collect any personally identifiable data.

All information entered in the App (trip names, expense categories, amounts, participant names) is stored exclusively on your device, in the App's local database (SQLite via SwiftData).

Kubu uses PostHog, an anonymized usage-analytics service hosted in the European Union (eu.i.posthog.com), to measure general app usage (screens viewed, trip creation, adding an expense, paywall display, purchase or restore). These events contain no personally identifiable data: no name, no amount, no entered content.

Kubu:

  • does not transmit any data you enter (trips, expenses, participants) to third parties,
  • only sends anonymized usage statistics via PostHog,
  • contains no advertising SDK and no advertising tracker,
  • does not collect advertising identifiers (IDFA).

3. System resources

Photo library (optional)

Kubu can save a trip summary to your photo library only if you explicitly tap the "Save to Photos" button. Photo library access is never triggered automatically.

Kubu never reads your existing photos. Access is strictly limited to adding an image generated by the App.

User preferences (UserDefaults)

Kubu uses local device preferences (UserDefaults) to remember your in-app settings, for example your default currency. These data never leave your device.

4. Data sharing

Kubu does not share any data you enter (trips, expenses, participants) with third parties, advertising partners or governments, except where legally required. Only anonymized usage statistics are sent to PostHog (see section 2), and are never resold to third parties.

5. Storage and security

All your data is stored locally on your iPhone, in the App's secure sandbox. It is protected by iOS's standard security mechanisms (storage encryption, app isolation).

Uninstalling the App permanently deletes all your data.

6. Minors

Kubu collects no personally identifiable data and does not specifically target minors. The App is suitable for all ages.

7. Changes to this policy

If this policy is materially changed, the date at the top of this document will be updated.

8. Contact

For any privacy-related question about your data in Kubu, contact the developer via the App Store product page or at alexandre-paul@outlook.com.

The data you enter in Kubu (trips, expenses, participants) stays on your device. Only anonymized usage statistics are sent via PostHog.
