App and website privacy
The offline app and this website are separate systems. Read NullKey’s published app privacy policy for the vault, unlock methods, imports, backups and support correspondence.
This product website includes Google Analytics, which stays off until you accept it in the consent banner. See Alvento’s website privacy notice for details. This applies to the website only: Google Analytics is not part of the NullKey app and does not see your vault or how you use the app, which has no internet permission. This product section is hosted with Alvento’s main website. Hosting services may process request and operational information to serve pages. Visiting a website still makes network requests, even though the app itself works offline.
