Consent

We should inform the users:

• The driving force is privacy
• Uninstalling before migration will disable preserveLegacyExternalStorage and they will need to perform a manual migration
  • Just tell them not to uninstall
• Syncing will temporarily be disabled
• Uninstalling during the process may cause data loss
• Uninstalling after the process will delete all data instead of just settings
• How long this will take

We should obtain explicit consent:

• Since we are moving files, this puts data itegrity at (low) risk
• To reduce issues from users uninstalling

We may inform users:

• Syncing and importing will be much faster
• The new location of storage
• USB access only

We do this via a link to https://github.com/ankidroid/Anki-Android/wiki/Storage-Migration-FAQ
