Every rate in the app carries a validity date
Laws change; without a cloud the app cannot know. So every monetary constant – VAT, the attorney calculation base, notary tariff, Eurocodes – is stored with its validity and source. The app shows the date it was verified and warns when it needs its annual update.
New rates, amended laws and historical versions for the next year. One download, no registration, no auto-renewal.
per app · first 12 months included in the licence
Updating is a choice, not a condition. Without it the app simply shows that it calculates as of the last revision date.
Buy once – the app keeps growing and updates itself over the web, no app stores. 12 months of updates included · last update Thursday 22 October 2026
