Personal use means non-commercial... which means a "logo" would most likely be outside the realm of personal use and a possible violation of licensing. There's no way to be certain without reading the actual license.
Scanning, screencaps, tracing, reformatting, etc., something does not change copyrights. Thinking that altering something by X% and you're "okay" is a complete myth. There's no such leeway. Only altering something so it is unrecognizable is okay... in which case, why bother trying to obfuscate the original item at all?
