1. About this policy
This policy covers the Cost Control mobile application for iOS and Android and this support website. For questions about our handling of information, contact the developer at bestban@yandex.com. Available features depend on the app version and platform.
2. Information stored on your device
The app stores expenses, income, transaction notes, categories, budgets, recurring records, preferences and app-lock settings locally. Core record keeping does not require a Cost Control account. We do not upload your financial records to a developer-operated database, and do not send the content of those records to advertising or purchase providers.
If you enable biometric unlock, authentication is performed by your operating system. The app receives the authentication result, not your fingerprint or face template. Reminder permissions are used for local notifications that you enable.
3. Optional backups and exports
When you choose cloud backup, your backup is sent to iCloud Drive on iOS or the app's private application-data area in Google Drive on Android. Google sign-in is used for the Google Drive connection. If you enable automatic backups, the app may update your backup without asking on each occasion. You can turn automatic backup off in the app.
You can also export reports or share a backup through the system share sheet. The selected service or recipient receives the file, including the financial information it contains. Backups and exported files can contain sensitive information; manage their access and deletion in the service or storage location you use.
4. Advertising and consent
The app uses Google AdMob for optional rewarded ads. Google and its advertising partners may process identifiers, IP addresses, device and app information, diagnostics, and ad views or interactions to deliver and measure ads, prevent fraud, and, where permitted and consented to, personalize advertising. IP addresses may be used to estimate approximate location. We do not request precise device location for ads.
Where required, Google User Messaging Platform (UMP) presents a consent message before ad requests. You can manage or withdraw your advertising choices through Settings → Ad privacy when those options apply. On iOS, the operating system may ask for App Tracking Transparency permission. You can change that permission in iOS Settings. Refusing tracking does not prevent use of the core app.

5. Purchases and subscriptions
Apple App Store or Google Play processes payment. RevenueCat helps verify purchases, restore access, and manage Premium entitlements. These services may process an app-specific user identifier, purchase receipts or tokens, product and subscription information, and technical device or app information. We do not receive your full payment-card details. See RevenueCat's Privacy Policy, Apple's Privacy Policy, and Google's Privacy Policy.
6. Support and website access
If you email us, we receive your email address and the content you send to handle your request. Please share only the information needed to explain your issue. This website does not add analytics or advertising scripts. Its hosting provider may keep access and error logs containing technical request information, such as IP address, requested URL and time, for operation and security.
7. Retention, deletion and your choices
You control your local records and can edit or delete them in the app. Removing the app generally removes its local data, subject to operating-system backup and restore behavior. Deleting a local record or uninstalling the app does not automatically delete previously exported files or cloud backups, or cancel a subscription. Delete those copies with your cloud or storage provider and manage subscriptions through the store.
Purchase and advertising providers retain information according to their policies and applicable requirements. Depending on your location, you may have rights to access, correct, delete, restrict or object to processing of your personal information, request portability, withdraw consent, or complain to a competent data-protection authority. Contact us to make a request about information we hold. We cannot retrieve financial records stored only on your device.
8. Security, international processing and children
We use available platform controls to protect information, but no storage or transmission method is completely secure. Providers may process data outside your country as described in their policies. The app is not directed to children under 13. If you believe a child has sent personal information to us, please contact us.
9. Changes and contact
We may update this policy as the app or its services change. The date above identifies the latest version. For privacy questions and requests: bestban@yandex.com.
