abstract = {We present measurements of $B^{+}\rightarrow\rho^{+}\gamma$
and $B^{0}\rightarrow\rho^{0}\gamma$ decays using a combined
data sample of $772 \times 10^6$$B\overline{B}$ pairs
collected by the Belle experiment and $387\times
10^6$$B\overline{B}$ pairs collected by the Belle II
experiment in $e^{+}e^{-}$ collisions at the $\Upsilon (4S)$
resonance. After an optimized selection, a simultaneous fit
to the Belle and Belle II data sets yields $114\pm
12$$B^{+}\rightarrow\rho^{+}\gamma$ and $99\pm
12$$B^{0}\rightarrow\rho^{0}\gamma$ decays. The measured
branching fractions are $(13.1^{+2.0 +1.3}_{-1.9
-1.2})\times 10^{-7}$ and $(7.5\pm 1.3^{+1.0}_{-0.8})\times
10^{-7}$ for $B^{+}\rightarrow\rho^{+}\gamma$ and
$B^{0}\rightarrow\rho^{0}\gamma$ decays, respectively, where
the first uncertainty is statistical and the second is
systematic. We also measure the isospin asymmetry $A_{\rm
I}(B\rightarrow\rho\gamma)=(10.9^{+11.2 +7.8}_{-11.7
-7.3})\\%$ and the direct CP asymmetry
$A_{CP}(B^{+}\rightarrow\rho^{+}\gamma)=(-8.2\pm
15.2^{+1.6}_{-1.2})\\%$.},
