Open a backup without Kuriosa
Choose a Kuriosa backup and type your recovery key. Your browser decrypts it on this computer and writes the same files as Export everything: a spreadsheet, CSV and JSON files, and every photo and document.
Everything happens on this computer: the backup and the key never leave it, and this page sends nothing.
Works in current versions of Chrome, Edge, Firefox, and Safari. For backups with many gigabytes of photos, use Chrome or Edge on a computer: they write the files straight into a folder.
