## What is S3Deck?

S3Deck puts AWS S3 and every S3-compatible storage on your iPhone — Cloudflare R2, MinIO, Backblaze B2, DigitalOcean Spaces, Wasabi, Ceph and any custom endpoint. Check a bucket, grab a file, share a link or fix a bucket setting without opening a web console.

BROWSE AND PREVIEW
• Folders and files laid out for the phone: tap to open, long-press to select several, ⋯ for every action.
• Preview photos, PDFs, video, audio and text right in the app.
• Filter a folder instantly, or search a whole bucket.

UPLOAD AND DOWNLOAD
• Upload from the Files app, iCloud Drive or any file provider.
• Downloads land in S3Deck's own folder, which you also find in the Files app under On My iPhone.
• A live transfer queue with retry and cancel; large files go up in parts.

MANAGE OBJECTS
• Create folders, rename, copy, move and delete.
• Edit metadata and headers, tags, storage class and permissions; browse and restore versions.

SHARE IN A TAP
• Presigned links with an expiry, public/private toggles and copy-ready object URLs.
• Open downloaded files in other apps through the share sheet.

BUCKET SETTINGS
• Bucket policy editor with validation and ready-made snippets.
• CORS rules, lifecycle rules, versioning, ACLs and access logging.

PRIVATE BY DESIGN
• S3Deck connects directly from your iPhone to your storage endpoint. Your files and credentials never pass through any server of ours — there isn't one.
• Secret keys are kept in the iOS Keychain.
• Mark production connections read-only to block every delete and overwrite.
• No analytics, no tracking, no account.

Works with the same connections as S3Deck for Mac, Windows and Linux. Available in English and Vietnamese.
