Where Substack keeps newsletters in cloud plus reading cache on Android and iPhone. Exact folders are covered below.
Last updated
Substack is newsletters cloud with phone reading. Publications, subs, and posts live in your account. The phone caches reading lists and audio.
Same email means same inbox of writers. Exact cache names shift with reader versus publisher builds. Keep online during swaps so reads upload. If subs vanish, check the email first. A work versus personal split is the usual empty feed cause with newsletter apps. Check the in app storage readout when sizes look wrong on different releases. When in doubt, verify paths inside the app before trusting a remembered folder.

Sign in on the new phone with the same email and subscriptions return from the cloud. Phone holds login and reading cache only. Posts read from account. Check the email before wiping, since a second account shows empty and hides paid pubs.
Does Substack back up my subscriptions?
