Illustration explaining Proprietary

Proprietary software is owned by a company which restricts the ways in which it can be used, modified, or redistributed.

Users normally need to pay to use the software, cannot read or modify the source code, and cannot copy the software or re-sell it as part of their own product. Common examples include Microsoft Excel and Adobe Acrobat. Non-proprietary software is usually open source.
