This Privacy Policy describes how Bitcoin & Satoshi Calculator / Convertor (the "App") collects, uses, and discloses your information. This App is developed by Cosmic Tools and Games ("we," "us," or "our").
By downloading or using the App, you agree to the terms of this Privacy Policy.
A. Information You Provide Directly The App does not require you to create an account, log in, or provide any personal identification (such as your name, email, or phone number) to use its primary features.
B. Financial Data (Local Only) Any financial data (such as Bitcoin amounts, Satoshi values, or fiat currency inputs) that you enter into the calculator is processed locally on your device. This data is not transmitted to our servers and we do not have access to it.
C. Information Collected Automatically (Third Parties) While the App itself does not store your personal data on our servers, we use third-party services that collect information to provide advertisements, analyze performance, and improve stability.
Google AdMob: We use Google AdMob to display advertisements. AdMob may collect and use unique device identifiers (such as your Advertising ID), approximate location, and interaction data to show personalized or non-personalized ads and to prevent fraud.
Google Firebase Crashlytics: We use Crashlytics to monitor app stability. If the App crashes, Crashlytics collects anonymous crash logs, stack traces, and device state information (e.g., device model, operating system version, free RAM). This data helps us identify and fix bugs.
D. Local Storage The App uses your device's local storage (Shared Preferences) to save your personal settings, such as:
Selected Theme (Light/Dark/System)
Preferred Fiat Currency (e.g., USD, EUR)
Last used Unit (Bitcoin vs. Satoshi)
Cached Exchange Rates
This data is stored solely on your device to improve your user experience and is not transmitted to us.
To provide real-time Bitcoin exchange rates, this App connects to public APIs provided by third parties. When the App fetches a rate, your IP address is visible to these services as part of the standard internet request.
Coinbase API: Used to fetch current spot prices.
CoinGecko API: Used as a fallback source for price data.
These services operate under their own privacy policies.
We use the limited information described above to:
Display current exchange rates.
Remember your preferences between sessions.
Display advertisements (via AdMob).
Monitor App Health: Analyze crash reports and diagnostics (via Firebase) to fix bugs and improve performance.
We do not sell your personal data. Data collected by third-party services (AdMob and Firebase) is processed according to Google’s Privacy Policy.
AdMob: Used for Advertising and Marketing.
Firebase: Used for Analytics and App Functionality.
The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us so we can resolve the issue.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this page periodically for any changes.
