Keepy gives your private photos, videos and documents a separate home on your iPhone. START WITH YOUR FIRST FILE Create your PIN and open your vault. Add photos, videos or documents, organize them into albums and return to your saved collection whenever you need it. Viewing saved files works offline. CAREFUL IMPORTS Keepy checks that a copy was written and its record saved before offering to remove the original from Photos. Import results show what succeeded and what needs another attempt. Removing originals is your choice. BACK UP AND RESTORE Create a ZIP backup of your photos, videos, documents and albums. Password protection is enabled by default, and Keepy verifies the archive before sharing. Restore a Keepy backup into a vault while keeping existing files. Store the archive outside Keepy and keep its password somewhere safe. PINs, browser sessions and settings are not included. SEPARATE VAULTS Use different PINs for separate collections. Optional decoy vaults and repeated entry of the main PIN can be configured after setup. Choose another app icon for your Home Screen. These features offer discretion; they cannot guarantee protection against inspection or coercion. MORE WAYS TO USE YOUR VAULT Browse with a separate web session for each vault, open Telegram or WhatsApp web sessions, and use on-device photo enhancement. Online services require an internet connection and follow their own privacy policies. FREE AND PAID OPTIONS Start with a free vault with import limits and advertising. Paid plans offer larger or unlimited allowances and remove ads; unlimited storage is limited by your iPhone's free space. Everything you added before version 1.11 always stays accessible. Without an active plan, your newest items within the free limits stay open; other items are locked but kept, can be deleted at any time, and are always included in Keepy backups. PRIVACY AND RECOVERY Vault files stay in Keepy's storage unless you choose to share, export or upload them. iOS Data Protection protects files on the device; the vault PIN is an app lock, not a file-encryption key. Keepy uses analytics and ads, with controls in Vault settings. There is no automatic cloud recovery and no forgotten-PIN reset. Back up before deleting the app or replacing your phone. SUBSCRIPTIONS Available plans, localized prices and any eligible free trial are shown before purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account subscription settings. Free trials are available only to eligible accounts for the selected plan.
