@deusalgor thx

On pc: C: - users - username - appdata - locallow - numerology - simple planes - aircraft designs. I wrote that from memory, hope it is correct.

1. Find the simpleplanes folder.
2. Open and go to Files
3. It's the first thing

(I don't know where the simpleplanes folder is except on android, its device storage/android/data/com.jundroo.simpleplanes)
