We really like the idea you convey of 'secret' and 'private' but this logo is a little plain. Can you make it a little more unique? Or offer a few other options that are in this vein of secrecy?
some other concepts: kicked off high heels panties zippers lips with a finger in front of them as if to say 'shhh' maybe their could be something inside of the keyhole - like a peek into the forbidden area
Regarding text: -can you make the letters all caps and try different font styles? -we don't want handwriting fonts, scripts, or overly feminine fonts.
Thank you for the feedback and ranking. I think we approach your logo in 2 different ways: for me, less is more. I want to let the customer imagine what he might see through the keyhole (and not show him). You want something more illustrative with more details which, I'm afraid, it won't work in case you want an icon.
I wish you good luck in finding something that suits you best.
