Magic Tricks ๐Ÿง™โ€โ™‚๏ธโœจ

๐Ÿ‘‹Hi, ArcaneChat magician here ๐Ÿง™โ€โ™‚๏ธ this is the section where I teach you some magic tricks to help you get the full potential out of ArcaneChat

In today's lesson we will be looking at the image editor of ArcaneChat:

when you attach an image, before sending it you could click in the pencil โœ๏ธ icon to edit it, here you have all kind of cool tricks, from drawing to blurring a part of the picture, ex. to protect some faces

you can also put some text, what not many think of is that using the text option you can also enter arbitrary emoji, and then using two fingers to pan you can make it bigger or rotate it and put it the way you like, this gives you a lot of gadgets to add to make your images more fun

if you have kids in the family using the app they will love it, together with the drawing brush it is also a source of entertainment for small kids! (this was tested already! just a small advice: better do it in a dedicated profile or they might accidentally mess up your chats or send stuff to your contacts!)

And that is all for today ๐Ÿง™โ€โ™‚๏ธโœจ

Meta quietly disables end-to-end encryption for Instagram DMs โ€” a feature that was already there, protecting people.

E2EE isn't a bonus feature. It's the baseline. When it disappears silently, it's worth asking: who benefits from the change?

The architecture of trust is always a design choice. ๐Ÿ” #infosec #privacy #encryption
