Yes, I am quite aware of that thank you. BUT I am an avid believer in DEPTH of protection – and also my phone is sometimes ‘in the hands of others’ (for instance, taking photos). The sole reason that I use AxCrypt is for this Depth (for just a very few of my ‘very special’ files) – I am OK with my ‘transmission medium’ (SpiderOak, that does have log-off options of course) and also OK with my password manager (LastPass, that does have log-off options of course). Also, both have other-device options where I can kill a compromised password so that the old password is totally useless.
Whatever, Happy Christmas!
