The short version

Your household entries belong to you. Income, expenses, categories, and notes stay on your device. The app has no user account, bank connection, advertising, or cloud sync, and we cannot see your entries.

Only an optional Pro purchase involves services outside your device: the current iPhone app uses the App Store for payment, and RevenueCat checks whether Pro is active. If an Android version becomes available, Google Play will handle purchases on that platform. None of these services receives your household entries. The details and legal basis follow below.

Data stored in the app

To provide its features, the app keeps the following information on your device. Technically, it uses a local SQLite database:

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

To decide whether to offer the reminder option, the app keeps only on your device a capped count of newly saved expenses plus the number and date of “Not now” choices. Existing transactions and income entries do not advance this card, and the discovery state is not sent anywhere.

The operating system asks for notification permission only after you tap “Enable reminder.” Unless permission is granted, reminders stay off. Once enabled, the selected weekdays, time and the seed used to vary the daily saying stay on your device. The app schedules local notifications through the operating system without a server or push service. You can change or turn off reminders in the app or revoke notification permission in the system settings.

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 purchase 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 (Apple)

The app offers monthly and annual Pro subscriptions, a one-time Lifetime Pro purchase, and voluntary consumable tips through Apple’s in-app purchase system (StoreKit). Tips unlock nothing and can be purchased repeatedly. When you make a purchase or restore 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 provide purchases and 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.

Future Android version and Google Play

If an Android version with optional Pro purchases and tips becomes available, it will use Google Play’s billing system. When you make a purchase or restore purchase history on that platform, you will be connected directly to Google Play. Google will process your payment data, your Google Account, and purchase-related metadata under its own responsibility.

We will not receive your payment-card details from Google. Purchase history and subscription status needed to provide purchases and unlock Pro will be processed through RevenueCat as described below; Google will also provide aggregated sales and payout data through Play Console.

For users in the European Economic Area, Google services are generally provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Further information: Google Privacy Policy.

Purchase validation (RevenueCat)

To load purchase options, manage purchases and validate Pro access, we use the RevenueCat service. The provider is RevenueCat, Inc., 1032 E Brandon Blvd #3003, Brandon, FL 33511, 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 may receive this ID, the device type, operating system, last-seen time, and purchase and subscription information provided by Apple or, if the Android version becomes available, Google Play. This information may include the Apple receipt file or Google purchase token and events 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 purchase or 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 free backup creates a JSON file containing all transactions and categories. You decide where to keep it, using the storage and sharing options on your device, and when to restore it. We do not operate our own backup service and have no access to your backup files.

On iPhone, the app marks its Documents, Application Support and Preferences directories as excluded from iCloud and Finder device backups. The local database and app preferences are therefore not restored from those device backups. iOS may still show a small Haushaltsbuch entry in backup settings because system-managed app metadata can remain; this does not mean that your transactions or categories are included.

What this app does not do

• No advertising or tracking SDKs, no cross-app tracking, and no advertising identifier
• No behavioral 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 [email protected] 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: [email protected], Website: https://www.ldi.nrw.de/.

We adapt this privacy policy when the app, services used or legal requirements change. We will inform you of material changes via an app update or on this page.
