Wuala // was a secure online file storage, file synchronization, versioning and backup service originally developed and run by Caleido Inc. It is now part of LaCie, which is in turn owned by Seagate Technology. The service stores files in data centres that are provided by Wuala in multiple European countries (France, Germany, Switzerland). An earlier version also supported distributed storage on other users' machines, however this feature has been dropped. On 17 August 2015 Wuala announced that it was discontinuing its service and that all stored data would be deleted on 15 November 2015.

Any registered user can:
- keep files private
- share files with other registered users
- share files with unregistered users, through a keyed hyperlink
- publish files
- file synchronization
- file versioning.
Registered and unregistered users can:
When a user adds a file to Wuala, or saves changes to a file that is served by Wuala, the user's local copy of file is:
- first encrypted
- then chunked into redundant fragments using Reed-Solomon error correction codes.
- The fragments are then uploaded to the data centers
Wuala offered free accounts that had 5 GB of storage for no charge. As of 11 June 2014 they shifted to a paid-only service. As of the end of 2014 they will no longer support any form of free-only storage, shifting entirely to a payment based usage model.
Users of joint products may start with greater amounts of storage for a limited period:
- with a LaCie external hard disk drive, 10 GB for one year
- with a LaCie USB flash drive, 4 GB for two years.
Additional storage may be bought. As of June 2014, the referral system was shut down due to the new paid-only policy.
For bought storage: prices range from 29 EUR/year for 20 GB to 999 EUR/year for 1 TB. Pricing changed in June 2014: The storage plan starts with 0.99 € per month (9 € per year) for 5 GB and ends at 159.90 € per Month (1799 € per year) for 2 TB of storage.
One of the distinguishing features of Wuala, the ability to trade local disk storage space against cloud storage, is no longer available.
The user interface offers most of the features that are normally associated with a file manager. Additional features come through integration.
- on any number of Linux, Mac OS X and Microsoft Windows computers
- with FUSE, MacFUSE and Dokan respectively for file system integration.
Wuala Webstart and web browsers
Through a web browser, on a computer that has Java installed:
- the user can start/trust a Java applet, which downloads and runs a class loader allowing fast start of the latest version of the Wuala application.
If the computer is without Java, or if running of the class loader is prevented:
- any folder that is public, or shared with a weblink, can be browsed.
Support for the following may be limited:
According to the FAQ, Wuala employs full client-side encryption. All files and their metadata – most OS X metadata is not supported – get encrypted before they are uploaded. The encryption key is stored such that no one, not even LaCie that operates the service, can decrypt the stored files. The disadvantage of this is that Wuala has no password recovery and all data processing needs to be done in the client (for example creating a search index). The advantage is significantly improved privacy.
Since the source code to Wuala has not been released, it is difficult to ensure that the software does what it states it does (including proper client-side encryption). Also, updates are pushed automatically to the client machine. These facts mean that users of Wuala are not safe from possible backdoors in code.
