| File content | Preview, edit, copy, move, rename, archive, extract, convert, play, share, scan, or otherwise complete the action you selected. | The file’s existing location, a destination you choose, temporary working memory, or app-private storage for specific features. |
| File metadata | Show names, paths, sizes, dates, MIME types, categories, media details, checksums, archive entries, and sort or search results. | Read from Android storage and held in bounded local caches where needed. |
| Preferences | Remember theme, layout, navigation, viewer, performance, Home, and feature choices. | App preferences on the device; eligible preferences may participate in Android backup. |
| Favorites, pins & recents | Return to locations or files you chose and show recent activity. | Local app storage. Removing an entry from these lists does not delete the underlying file. |
| Transfer state | Show progress, completion, failure, and notifications for operations you started. | Memory and local operation state; Manage on PC session lists clear when that server stops. |
| Version snapshots | Keep a reversible copy before the built-in text editor overwrites a local file. | App-private storage. History is bounded and older snapshots are pruned automatically. |
| Saved connections | Reconnect to SMB, FTP, WebDAV, Nextcloud, or compatible NAS locations you configured. | App no-backup storage; passwords are encrypted with a device-bound Android Keystore key. |
| Purchase entitlement | Determine whether Google Play reports Fylo Pro as active, pending, canceled, refunded, or unavailable. | Queried through Google Play Billing and cached locally; Fylo operates no payment database. |
| AI models & indexes | Support optional on-device AI features after you install them and grant the related consent. | App-private or no-backup storage, never uploaded to Fylo. |
