** Hi I purchased on my iPhone but I want to purchase on my desktop bc I have more entries.
Diarium version: 2.9.13
OS + version: latest (Monterey macOS vers 12.4)
I am not able to issue refunds for Apple purchases. Apple doesn't provide developers with that ability.
You need to contact Apple support, they can refund the purchase. You can also try what is suggested here: https://support.apple.com/en-us/HT204084
