All appsLicence to the work – monthly, yearly or lifetime, no account; your data stays yours.
All appsA licence at €19 a month pays for itself in under a week of work. You save ~€90 a month, ~€71 net after the licence.
Conservative: Sovereign saves half of that time. A typical cloud tool over 5 years: €2340.
One key for the whole team – organisation name signed into the licence, device management and a shared audit export. Monthly or yearly, cancel anytime.
The first twelve holders receive a licence numbered 01–12 – at the price of a regular licence.
Offline does not mean frozen in time. Every release is recorded here, the roadmap is public and updates follow rules we can keep.
Refreshed consolidated texts from official sources as of 22 Oct 2026: Czechia 26 acts (e-Sbírka open data), Germany 65 (Federal legal information portal and Gesetze im Internet – BMJ; Bayern.Recht), Austria 40 (RIS – Federal Chancellery).
“Report a discrepancy” button in the status bar and footer of every app: one e-mail to both official contacts at once with pre-filled context – app, module, jurisdiction, version, address, time; the text is copied as well, so it works offline.
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
