ctLibrary is a free offline-first document and notes library. Keep PDFs, Word, Excel, PowerPoint, images, text files, and your own typed notes organized in one place — on your device, and optionally synced across your Apple devices through your own iCloud account. ORGANIZE - Folders contain Categories. Categories contain documents and notes together. - Personal folder with Important Documents and Personal Notes categories, ready on first launch. Create your own folders and categories anytime. IMPORT DOCUMENTS - Import PDFs, Word, Excel, PowerPoint, images, text, CSV, RTF, and Markdown. - Share into ctLibrary from Mail, Files, Safari, cloud-drive apps, and more. - Manual import from the Files picker also supported. READ, SEARCH, SHARE - Open PDFs directly in the app with pinch-to-zoom and pagination. - Preview images, text, and CSV files in-app. - Best-effort preview of Office files; fall back to Open With for full editing. - Fast offline search across document titles, descriptions, file names, and note text. - Favorites and Recent Items for one-tap access. NOTES - Type quick notes alongside your imported documents. - Notes search by title and body content. - Combined view shows documents and notes together inside each category. SYNC ACROSS YOUR APPLE DEVICES (OPTIONAL) - Turn on iCloud Sync in Settings to keep your library in sync between your iPhone and iPad through your own iCloud account. - Data stays in your iCloud account; Cozzitech operates no sync server and never sees it. - Sync is off by default — your library can stay 100% on-device if you prefer. OFFLINE-FIRST PRIVACY - Everything stays on your device (or in your own iCloud, if you turn sync on). We never see your documents or notes. - No analytics, no tracking, no advertising. - Optional App Lock with biometric unlock and recovery code. - Optional one-time email verification unlocks unlimited folders, categories, documents, notes, and outbound sharing. ctLibrary is built for people who want a reliable local reference library — emergency-management binders, work procedures, household paperwork, training materials, or anything you want at hand without depending on a third-party cloud.
