OmniGraffle
OmniGraffle is a Mac diagramming and vector graphics app for creating flowcharts, wireframes, layouts, and other precise visual documents.
What is OmniGraffle?
OmniGraffle is a native Mac graphics and diagramming app for building clear visual documents such as flowcharts, process maps, wireframes, org charts, layouts, and technical diagrams. It is designed for people who need more precision and structure than a simple drawing tool, including designers, analysts, project planners, engineers, and other office or technical users. The app supports both quick sketching and detailed document construction, so it fits early idea exploration as well as polished final deliverables. Common workflows include planning interfaces, explaining systems, mapping processes, and preparing visuals for presentations or documentation. OmniGraffle also works well for users who need reusable shapes, alignment tools, layers, and scalable vector output. Published by The Omni Group, it is part of a long-running Mac productivity and design lineup.

Safety overview
Status: Safe
OmniGraffle is legitimate productivity software for creating diagrams and graphics on your Mac. It normally needs access only to the files you open, save, import, or export, and that level of file access is expected for a document-based design app. If you use cloud storage or sharing features, the privacy and retention of those files also depend on the services you connect. Keep documents backed up if they matter to your work, especially before removing the app or clearing its support files.
Recommendation: Keep OmniGraffle if you use it for diagrams, wireframes, or visual planning. Remove it only if you no longer need the app, and expect any app-specific settings, templates, or local support data to stop being available afterward.
