Privacy Policy

Esther The Investor · Lumhera SARL · Effective October 7, 2026

1. About this policy

Lumhera SARL provides Esther The Investor, an educational game. This policy explains how the mobile app handles information.

2. Information collection, advertising and tracking

The app does not require a Lumhera account and does not ask you to provide personal information to Lumhera SARL. Lumhera SARL does not use the app to serve advertising, run developer-operated analytics, or track users across other companies’ apps or websites.

Apple, Google and their store services may process information independently when you download the app, make a purchase, or restore a purchase. Their processing is governed by their own privacy policies.

3. Local game data

Game progress, completed stages, in-game results, language, audio, display settings and purchase entitlements may be saved locally on your device using the operating system’s app storage. Lumhera SARL does not receive this local game data. Deleting the app, clearing app data, resetting progress, or changing devices may remove local progress and settings.

4. Downloads and in-app purchases

On iPhone and iPad, downloads and in-app purchases are processed by Apple through the App Store. On Android, they are processed by Google through Google Play. The store controls payment and may process your store account, payment, transaction, device and diagnostic information. The app does not receive your full card number or store password.

To display products, complete a purchase, check an entitlement, or restore a non-consumable purchase, the app communicates with the relevant store. The app receives the product identifier, purchase status and entitlement or transaction information needed to unlock purchased content and save that entitlement locally. Restoration requires an internet connection and the same store account used for the original purchase.

5. Children’s privacy

The app does not knowingly ask children or other users to submit personal information to Lumhera SARL. If a parent or guardian believes that a child has sent personal information to us by email, please contact us so we can respond appropriately.

6. Changes

We may update this policy if the app, its SDKs, store requirements, or applicable law changes. We will revise the effective date when an update is published.
