About this app

BTC Gains Checker — Bitcoin portfolio
Private BTC portfolio overview

Record your Bitcoin transactions and thus monitor the development and value of your portfolio - in real time, without compromising on privacy.
BTC Gains Checker stores your transaction data exclusively on your phone. There is no need to create a user account and send data to the server. The app connects to the Internet only to get the current BTC price.
The optional data backup function works by sending data encrypted with the AES-256-GCM algorithm to the Google server, i.e. with an encryption key derived from your access code. Only an unreadable encrypted file gets to the Google server - neither the operator nor Google can read your transactions.

FUNCTIONS
Portfolio overview - amount of BTC held, amount of FIAT invested, portfolio value, average purchase price and current profit or loss, current BTC price.
Interactive graph - view your portfolio over time.
Landscape graph - rotate your phone to landscape to view a larger graph.
Historical P&L (Profit & Loss) – how the FIAT value of your BTC has developed over time based on real historical BTC prices.
Import and export transactions – bulk transfer of transactions without manual entry.
Support for multiple currencies – USD, EUR or CZK and the ability to combine them in transactions.
Passcode & Biometrics – protect access to the application with a passcode and Face ID or fingerprint.
Data encryption – the ability to turn on encryption of application data based on your passcode.
Encrypted backup – the ability to turn on backup to Google Drive. Data can be synchronized between your devices (same Google ID and same passcode). Data is encrypted directly on your device. Without your passcode, it is unreadable to anyone else.
Hide values ​​– pressing a button or turning the phone face down blurs the information, which contributes to your privacy.

PRIVACY & TECHNICAL SOLUTION
Most portfolio trackers require you to create an account and store your financial data on their servers. BTC Gains Checker works completely privately. Your data is never seen by the operator or Google.
User transaction data is stored locally.
No registration, no account, and no need to share data with the server.
The application communicates with the Internet only to get the current and historical BTC price.
The application does not contain any analytical or advertising SDKs. We only collect anonymous crash reports.
The passcode is used to unlock the application and encrypt data. Without the passcode, data cannot be decrypted.
Optional cloud backup and synchronization between devices uses end-to-end AES-256-GCM encryption with a key derived from your passcode. All devices must have the same passcode to synchronize. No one except you can read the data on the server.
