Overview

The “Haushaltsbuch & Budget Planer” app is a locally operating iPhone application. All income, expenses, and categories you enter are stored exclusively on your device. The app does not transmit this data to a server, a cloud, or any third party.

Processing outside your device is limited to the optional subscription system: Apple processes an in-app purchase, while RevenueCat loads offerings, validates subscription status, and provides purchase and subscription analytics. Both are described separately below.

Data stored in the app

The app stores the following data locally in a SQLite database on your device:

• Transactions: type (income or expense), amount, category, date, optional note, creation and update timestamps
• Categories: name, type, sort order
• App settings such as language and display preferences

The locally stored financial records contain no names, email addresses, phone numbers, postal addresses, advertising identifiers, or location data. There is no user account, no registration and no sign-in. For the optional subscription system, the RevenueCat SDK assigns a random pseudonymous App User ID to the installation as described below. If you delete the app from your device, the locally stored financial data is also removed.

The legal basis is Art. 6 (1)(b) GDPR (performance of the usage relationship) and Art. 6 (1)(f) GDPR (legitimate interest in the proper operation of the app). Since the data is processed exclusively locally on your device, processing by us as controller occurs only insofar as we provide the app.

In-app purchases and subscription (Apple)

The app offers an optional “Pro” subscription via Apple’s in-app purchase system (StoreKit). When you make a purchase or restore a purchase history, you are connected directly to Apple. Apple processes your payment data, your Apple ID, and purchase-related metadata under its own responsibility.

We do not receive your payment-card details from Apple. Purchase history and subscription status needed to unlock Pro are processed through RevenueCat as described below; Apple also provides aggregated sales and payout data through App Store Connect.

Provider: Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland. Further information: Apple Privacy Policy.

Subscription validation (RevenueCat)

To manage and validate the subscription status, we use the RevenueCat service. The provider is RevenueCat, Inc., 144 2nd St, San Francisco, CA 94105, USA.

Because the app does not provide RevenueCat with a custom user ID, the RevenueCat SDK generates a random pseudonymous App User ID and caches it on the device. A reinstall normally creates a new ID. RevenueCat receives this ID together with purchase history and subscription events provided by Apple, such as purchase, renewal, cancellation, and refund. RevenueCat uses these data to load offerings, determine whether Pro is active, prevent purchase fraud, and provide purchase and subscription analytics. RevenueCat does not receive your transactions, categories, notes, or backup files.

The legal basis is Art. 6 (1)(b) GDPR (performance of the subscription contract). RevenueCat may also process data in the USA. Where required, transfers are based on the EU-US Data Privacy Framework, where the recipient is certified for it, and additionally on EU Standard Contractual Clauses. Further information: RevenueCat Privacy Policy.

Backup and restore

The app allows you to manually export all locally stored transactions and categories as a JSON file. You can save the export file yourself, for example via the iOS Files app, or store it in a cloud of your choice. Re-import is also performed manually by you. We do not operate any backup infrastructure of our own and have no access to your export files.

What this app does not do

• No advertising or tracking SDKs, no cross-app tracking, no identifier for advertisers (IDFA)
• No behavioural or product-usage analytics libraries and no third-party crash reporting; RevenueCat processes only purchase and subscription analytics
• No connection to bank accounts or financial institutions for importing transactions
• No profiling, no automated decision-making within the meaning of Art. 22 GDPR
• No sale, no transfer and no commercial exploitation of your transaction data

Retention period

Transactions and categories stored in the app remain on your device until you delete them in the app or uninstall the app.

RevenueCat retains the purchase and subscription data it processes in accordance with its privacy policy and for as long as required to provide the service, meet legal obligations, resolve disputes, and enforce agreements.

Your rights

Under the GDPR, you have in particular the right to information, rectification, erasure, restriction of processing, data portability, and to object to processing based on Art. 6 (1)(f) GDPR. Where processing is based on consent, you may withdraw that consent at any time with effect for the future.

For data stored locally in the app, you can exercise your rights directly by editing or deleting them in the app itself. For data processed by RevenueCat, a message to support@kimaracode.com is sufficient; we will forward your request to RevenueCat.

Right to lodge a complaint

You have the right to lodge a complaint with a data protection supervisory authority. The competent authority is in particular the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen), Kavalleriestraße 2-4, 40213 Düsseldorf, Email: poststelle@ldi.nrw.de, Website: https://www.ldi.nrw.de/.
