Privacy Policy
Last updated: September 12, 2026
Purpose
SimHub is a private, single-owner application. It receives SMS messages from the owner's 4G modem and forwards those messages to the same owner by email.
Data processed
SimHub processes SMS message content and the associated phone numbers. This data is stored only on the owner's local device for 30 days and is then deleted.
How data is used
SMS messages and phone numbers are used only to forward received messages to the owner. They are not sold, shared, disclosed, or transferred to third parties.
Gmail access
SimHub uses Gmail OAuth only to send these email notifications. It requests only the https://www.googleapis.com/auth/gmail.send scope. SimHub does not read, modify, or delete Gmail messages.
Public website
This website contains only information about the project and this privacy policy. It does not expose the modem or the local SimHub control panel.
