Evidence stays separate from calculations
The invoice or warranty card you attach is kept as the original file. The dates and term you type are what the calculator uses, and you can note where you read them. Nothing is extracted automatically, and no calculation claims a manufacturer will accept a warranty.
Questions
Can I manage a household or small office?
Yes. Use the owner/location field for each item and filter by it. There is no cloud sharing; export and import a backup file to move a register.
How large can attachments be?
Up to 15 MB per file. Browsers limit total storage and may clear it under pressure, so keep your own copies of important receipts.
