By default Apple keeps the keys to iCloud Drive in its data centers and can decrypt your files, for example to restore them after a forgotten password. Advanced Data Protection, a setting turned on from an iPhone, iPad or Mac, deletes Apple's copy of the keys and leaves them on your trusted devices; Apple no longer offers it to new users in the UK. Even with it on, the file type, size, creation and modification dates and checksums of the file content and file name stay under keys Apple holds. With the setting on, iCloud.com cannot open your files until you allow web access, and then each session gets temporary keys from one of your devices.

Tresorit says files, file names and subfolder names are encrypted on your device, each with its own key. The names of top-level folders, their size and member list, and file size, type and creation time are not end-to-end encrypted. Recipients' public keys are vouched for by Tresorit's own certificate authority. Web Access decrypts files in your browser with code that Tresorit serves on every visit.

Penetration tests, a source code review and a cryptographic review of the end-to-end encryption and the web, mobile and desktop apps, carried out in August and September 2019. Commissioned by Tresorit.

Users in the US contract with Apple Inc. in Cupertino, California; users elsewhere contract with a regional Apple company, such as Apple Distribution International in Ireland. The terms are governed by California law, except for residents of the EU, the UK, Switzerland, Norway and Iceland, whose local law applies. Apple keeps the keys it can use in its US data centers and may store data with third-party data centers. In mainland China, iCloud is operated by GCBD (AIPO Cloud (Guizhou) Technology Co. Ltd) under its own terms.

Tresorit AG is registered in Zurich, and its terms are governed by Swiss law. Files of personal accounts outside Switzerland are stored on Microsoft Azure in Ireland, and files of Swiss customers in Switzerland; account metadata is always stored in Ireland.

Swiss Post acquired a majority stake in July 2021. Tresorit says it remains an independent company within the Swiss Post group, which runs it as part of its digital business services.

Deleted files stay in Recently Deleted for 30 days and can be restored. Pages, Numbers and Keynote documents keep a version history; Apple documents no version history for other files.

Personal Lite keeps 5 previous versions of each file, Personal Essential 10 and Personal Pro 25. Earlier versions can be downloaded but not set back as the current file. Deleted files and subfolders can be restored from the trash; deleted top-level folders cannot.
