Package: com.leakcheck.nexus
LeakCheck: Refrigerant Log stores everything you enter only on your phone. Digital NEXUS does not collect, receive, sell or share any of your data. The app has no account, no ads, no analytics and no in-app purchases.
The app keeps a leak-rate log for refrigeration and air-conditioning equipment: units, refrigerant additions, leak-rate results and service notes. This data is saved in the app's private storage on your device. It is never sent to us or to anyone else by the app.
The app asks for no device permissions: no camera, microphone, location, contacts or files. The current release declares zero internet or network-state permissions in its Android manifest, bundles its UI assets locally, and works 100% offline with zero network requests.
If you tap Share or Print, the report goes to the app or printer you choose (for example email, a messaging app, cloud storage or a print service). That only happens when you do it, and what that app does with the report is covered by its own privacy policy.
You can delete any record in the app. Clearing the app's storage or uninstalling the app deletes all of its data from your phone. Because we hold no data about you, there is nothing for us to delete on our side; you can still write to us with any question.
The app is a work tool for adults and is not directed at children.
LeakCheck: Refrigerant Log is an independent app by Digital NEXUS. It is not affiliated with, endorsed by or connected to the U.S. Environmental Protection Agency (EPA) or any government agency.
If this policy changes, the new version will be posted on this page with a new effective date.
