Notes[edit | edit source]

  1. A version that generally continued working even after the usual 90-day expiration (until it became incompatible with the production server). Signal stopped releasing such versions at some point.
  2. Android API level 20 is 4.4W, KITKAT_WATCH (see e.g. Unclear if Signal worked on this version.[source needed]
  3. "Apple ended active support for iOS 12 in September of 2019. We support older operating systems for as long as possible unless there is a technical limitation. This is not a decision we took lightly. Please also keep in mind that we have limitations on what operating systems we can support as we are a very small team and a non-profit organization. An iOS device running iOS 13 or later is now required to use Signal."—from a comment by Miguel-Signal on signalapp/Signal-iOS#5661
  4. About monthly in-app donations: "In regards to changing your subscription, your account should be in an auto-cancel state within a few days and the donation should be cancelled within a billing cycle. So at most, you will only be charged for one more month."—from a comment by Miguel-Signal on signalapp/Signal-iOS#5661
