Am I breaking rules by putting book ratings out into the ether?

I read... a lot. And I have a need to then 'tick' off those books virtually by marking them off my goodreads,bookmory, and other apps.

I give a rating - I think I'm always fair with my ratings:
5⭐ : couldn't put it down, lives in my brain loved the characters, the plot, completely absorbed.- will fight people to read more
4⭐: really enjoyed, struggled to it down, enjoyed the overall story and will read more by the author always
3⭐: enjoyed and finished the book happily. will probably read more but not necessarily leaping lines to get there.
2⭐: it was okay. I didn't necessarily hate it but didn't love it either. probably unlikely to read more.
1⭐: very likely hate read as I can't dnf a book.


My usual ratings are 3-5's... and I always 'rate up' so if I think it's a 3.5 star, I'll give a four. But I was talking with other authors and there seemed to be a split on whether authors should rate other authors. It was pretty much 50/50 to it being a resolute NO and a Yes, but always 4 stars and up.

My personal opinion is telling authors they can't rate others authors is like telling a chef they can't eat another chefs cooking. As long as feedback is constructive, fair and honest surely it's welcome?

Not everyone will like my books and I'm not going to love everyone elses - but that's okay.
