Good to know about this tool

What does this tool do?

Logs income and expenses chronologically with a running balance — saveable as an encrypted .itss profile.

Why does it exist?

Typical use cases
  • Track a small shop's daily cash register
  • Prepare cash income and expenses for your tax advisor
  • Keep a personal household ledger
Best practices & notes
  • Save and export the profile regularly with a strong password
  • Use GoBD-compliant software for tax-binding cash bookkeeping

Frequently Asked Questions

Is this a legally compliant cash book?

No, this tool is for simple tracking only — for legally compliant cash books, use a specialized system or your tax advisor.

Are my entries stored?

Only if you explicitly choose to: use the profile manager to save your entries as an encrypted (.itss) profile and reload them later. Without a saved profile, everything is lost on reload.

Is my saved profile secure?

Yes, the profile is encrypted with AES-256-GCM and unreadable without your password.
