Android and iOS data collection
One network mitigation for Apple devices (e.g iPads) without a cellular baseband is to have a router block all connections to 17.0.0.0&#x2F;8, except a once a week check for OS and app updates. This assumes no use of iCloud, which would siphon much more data than described in this article.  It&#x27;s also necessary to disable Siri on-device search (e.g. &quot;Learn from this app&quot;) and Spotlight indexing of in-app content (per-app setting for &quot;Show app in Search&quot;), including E2E encrypted messengers like Signal and Wire.<p>For phones, the only mitigation is a lifestyle change to switch from always-reachable to scheduled availability windows or the always-async workflows of pre-mobile computing.  A faraday bag can deny realtime telemetry, even if it&#x27;s cached for relay when connectivity returns.
