CBR Currency
Last updated: November 9, 2026
This policy explains how CBR Currency for Android and iOS (package / bundle identifier net.inettools.cbrcurrency, Russian name «Калькулятор валют») processes data when converting currencies with official Bank of Russia rates. The application is developed by InetTools and is not an official Bank of Russia application.
Developer and Contact
The app is published by InetTools. For privacy questions, contact us at support@inettools.net.
Purpose of the App
The app converts amounts between RUB and popular currencies using official Bank of Russia exchange rates. Exchange rates are public reference data and are not the user's personal data.
Network Requests and API
To calculate a conversion, the app calls the InetTools API: https://ru.inettools.net/api/currency/convert. The request contains the entered amount, source currency, and target currency. These values are needed only to perform the calculation. Rate history is loaded through /api/market-indicators/history with the selected indicator code and period.
The InetTools server may automatically receive standard technical request data such as IP address, user agent, request time, requested URL, response code, and delivery error details. This data is used for security, diagnostics, and stable API operation.
Local Storage
The current app version does not require sign-in and does not store conversion history in a separate user database. The entered amount, selected currencies, and result are kept in the app's runtime screen state while the user is using the screen. The theme preference, random analytics identifier and a bounded queue of anonymous events are stored locally.
Analytics and Advertising
The app uses AppMetrica and a dedicated PostHog project for product analytics, and Sentry for error and stability diagnostics. These SDKs may receive technical device details, app version, session, launch event, and error information. AppMetrica is configured without location tracking, and the Android build excludes the advertising identifier module. AppMetrica may estimate the country or region from an IP address, without requesting device location. We do not use advertising SDKs and do not sell users' personal data.
PostHog uses https://posthog.inettools.net and receives only screen opens, conversion and history request starts and actual completions, theme changes and closed error categories. Properties include app version, language, form factor, window-size category, orientation and operation duration. A random anonymous installation/session identifier is used. IP addresses are anonymized; person profiles, screen/session recordings, automatic interaction capture and geolocation are disabled. Amounts, currency pairs, exchange rates, conversion results, entered text, URLs and raw errors are not sent to PostHog.
Device Permissions
The app needs internet access to call the currency calculator API, send AppMetrica and PostHog technical analytics, and send Sentry error reports. It does not request access to contacts, camera, microphone, SMS, calendar, user files, precise or approximate location, or payment data.
On iOS, these network requests use the standard system network connection; no access to the photo library, camera or files is requested. The app does not request the advertising identifier or permission to track users across other companies' apps and websites.
External Sources
Exchange rates are aggregated server-side by InetTools from public Bank of Russia exchange-rate data. The app does not call the Bank of Russia website directly from the user's device.
Data Deletion
Users can delete local app data through Android system settings or by deleting the app on Android or iOS. For questions about API technical logs, contact us at support@inettools.net.
Children
The app is not specifically directed to children and does not include account registration, user content publishing, or communication features between users.
Policy Changes
We may update this policy when the app, API, or legal requirements change. The current version is published on this page.
