Koinkat v0.1.1

Koinkat is a local-first personal finance manager for the desktop. It tracks accounts and spending across multiple currencies, imports transactions from European banks via PSD2 (Enable Banking) with a learning categorization engine, split-expense tracking, and budgets - and every byte of data stays in a database on your own computer: no cloud, no account with anyone, no telemetry. Free software (GPL-3.0-or-later) for anyone who wants bank-connected finance tracking without handing their data to a service.

What changed in 0.1.1

• macOS builds are signed with an Apple Developer ID certificate and notarized by Apple, so the app opens with no security warnings.
• macOS builds are universal: they run on Intel Macs as well as Apple Silicon. 0.1.0 was Apple Silicon only.
• The app's typefaces are bundled instead of loaded from Google Fonts, so Koinkat contacts no font host and renders correctly offline.
• Refreshed the app icon set.
• Corrected the Enable Banking setup guidance in the README and the in-app guide: restricted-mode activation covers only the accounts you link in the Control Panel.
• Hardened budget writes: grouped budget changes now run as single atomic database batches, and a failed budget deletion reports why instead of failing silently.

Install notes - the full guide is in the README:

• macOS (Apple Silicon and Intel): download Koinkat_0.1.1_universal.dmg, open it, and drag Koinkat to Applications. The app is signed and notarized, so it opens normally with no extra steps.
• Windows: builds are not code-signed, so SmartScreen shows "Windows protected your PC". Click "More info", then "Run anyway". Alternatively, download the installer with curl.exe from PowerShell, which avoids the dialog entirely (commands in the README).
• Linux: the AppImage needs chmod +x; if it reports a FUSE error, install libfuse2 (sudo apt install libfuse2) or run it with --appimage-extract-and-run. deb and rpm install normally.

Install notes - builds are unsigned; the full guide is in the README:

• Windows: SmartScreen shows "Windows protected your PC". Click "More info", then "Run anyway".
• macOS (Apple Silicon only): recommended: download the .app.tar.gz with curl in Terminal, unpack, and move to Applications - curl downloads carry no quarantine flag, so the app opens with no dialog (exact commands in the README). If you used the .dmg in a browser instead and macOS says Koinkat "is damaged and can't be opened", it is not damaged: run xattr -cr /Applications/Koinkat.app and open it again; an "unidentified developer" block clears via System Settings > Privacy & Security > Open Anyway.
• Linux: the AppImage needs chmod +x; if it reports a FUSE error, install libfuse2 (sudo apt install libfuse2) or run it with --appimage-extract-and-run. deb and rpm install normally.
