BTC Purchase Tracker does not require:
- an account
- a cloud service
- a wallet connection
- private keys or seed phrases
The application stores its data locally in:
btc-purchase-tracker.sqlite
On first launch, you choose the folder where the database will be stored.
When creating a new database, BTC Purchase Tracker asks you to choose either EUR or USD.
The selected currency is permanently associated with that database and cannot be changed later. The application does not perform currency conversion.
If you want to track purchases made in a different currency, use a separate database.
Financial and Bitcoin values are stored using integer units:
- fiat amounts are stored as integer cents
- Bitcoin amounts are stored as integer satoshi
BTC values shown in the interface are calculated from satoshi. Bitcoin is not stored using floating-point values.
The main window provides:
- total fiat spent
- total BTC purchased
- total satoshi
- average purchase price per BTC
- year-based filtering
- chronological purchase-price chart
- sortable purchase table
Each purchase can contain:
- date
- site / exchange
- fiat amount
- BTC
- satoshi
- TX / transaction ID
BTC and satoshi remain mathematically consistent when entering or importing data.
BTC Purchase Tracker can import CSV files using common column names such as:
Data,Date,Data acquistoSito,Site,Exchange,PiattaformaEuro,EUR,Euro spesiUSD,Dollari,Dollars,USD spentBTC,Bitcoin,BTC on-chainSatoshi,SatsTX,TXID,ID transazione
Supported separators include:
- semicolon (
;) - comma (
,) - tab
BTC or satoshi is sufficient. If both are present, they must represent the same amount.
Supported date formats include:
26/08/20262026-08-2626-08-2026
Before importing, the application displays a summary of:
- valid rows
- duplicate TX / IDs
- rows containing errors
Valid rows are then inserted in a single SQLite transaction.
BTC Purchase Tracker automatically maintains:
btc_purchase_tracker_autobackup.csv
in the same folder as the active SQLite database.
The file is refreshed after relevant database operations, providing an additional human-readable copy of the purchase history.
For a complete application backup, the SQLite database itself remains the primary file to preserve.
A diagnostic log can be exported from the Info menu when troubleshooting is required.
The exported log is limited to approximately 200 KB and contains technical application events only. It does not include purchase amounts, BTC / satoshi values, transaction notes, TX / IDs or the Lightning BOLT12 Offer.
The user's home-directory path is masked when it appears in operating-system error messages.
Prebuilt packages are available from the GitHub Releases section.
Download the Windows ZIP archive, extract it and run:
BTC-Purchase-Tracker.exe
The Windows release is portable and does not require a traditional installer.
Windows SmartScreen may display a warning for an unsigned application downloaded from the Internet.
The archive does not bundle the Microsoft Visual C++ runtime. If the application does not start or Windows reports a missing runtime DLL, install the latest official Microsoft Visual C++ Redistributable x64 from Microsoft's download page, then start the application again.
Download the Linux AppImage from the release assets. If it is supplied inside a ZIP, extract it first.
If necessary, make it executable:
chmod +x BTC-Purchase-Tracker-*.AppImageThen run it:
./BTC-Purchase-Tracker-*.AppImageNo system-wide installation is required.
Download the checksum file alongside the corresponding release asset. The Windows checksum covers the complete portable ZIP; the Linux checksum covers the AppImage.
On Linux, place both files in the same folder and run:
sha256sum -c BTC-Purchase-Tracker-1.0.0-x86_64.AppImage.sha256On Windows, calculate the ZIP hash in PowerShell and compare it with the .sha256 file:
Get-FileHash .\BTC-Purchase-Tracker-1.0.0-Windows-x64.zip -Algorithm SHA256A matching checksum checks file integrity against that checksum; it is not a publisher signature.
BTC Purchase Tracker is written in C++20 using Qt 6 Widgets and Qt SQL / SQLite.
