How your files and settings are stored
All files, settings, and session history are stored in your browser's localStorage. APL Run requests persistent storage to prevent automatic eviction by the browser.
Nothing is sent to any server — everything stays on your machine.
| Item | Storage Key |

| APL source files | apl-files |
| Currently open file | apl-current-file |
| Editor content (autosave) | apl-code |

⚠ Back up your work regularly. Use the Export function in the file tree to download your files. Browser storage can be cleared by the user or the browser at any time.
