Privacy Policy - Nummerkoll. Effective: 2026-10-16. Publisher: zenith-ops. Contact: zenith-ops@mail.grokbot.com

Summary
Nummerkoll processes everything on your device. We do not collect, store, sell or share the numbers you check, the pages you visit, or any browsing data.

What the extension does with data
- Numbers you type, paste or select (personnummer, organisation numbers, bank details, etc.) are checked locally in your browser. They are never sent to us or any third party, never written to storage, and not logged.
- Settings stored with chrome.storage: your language choice. Nothing else.
- The selected-text right-click menu passes the selection to the popup through temporary session storage, which the browser clears when it closes.

No tracking
No analytics, advertising, fingerprinting, remote code or cookies. The extension does not sell or transfer user data to third parties, and does not use data for purposes unrelated to the extension's single purpose, or to determine creditworthiness.

Your rights (GDPR)
Because we hold no personal data from local use, there is nothing to access or erase. You may complain to the Swedish Authority for Privacy Protection (IMY, imy.se).

Sensitive numbers
Personnummer are personal data in Sweden. Nummerkoll lets you validate them locally without transmission. You remain responsible for having a lawful basis when handling other people's personnummer.
