Where are the words added to User Dictionary stored?

Depending on the type of product used, the initial storage for words will be different.

• SpellCheckAsYouType (SCAYT) and WProofreader: By default, all words added using SCAYT and WProofreader User Dictionary functionality are saved  to the browser's local storage. Thus, all the words are stored on end user’s side and available from a particular browser only.
• WebSpellChecker Dialog (WSC): The words added using WSC User Dictionary functionality are saved in the browser's cookies on the end user’s side.

To access and use a personal dictionary from different browsers and machines (or devices) while working with the system, a user has to create a dictionary from:

• Dictionaries tab of SCAYT plugin for CKEditor 4;
• Options tab of WSC Dialog plugin for CKEditor 4;
• Dictionaries tab of WProofreader. 

After creation of a new dictionary, the words from the local storage and cookies respectively will be moved to a server. For the Server version, the dictionary is saved — on the client’s server where the WebSpellChecker application is installed and running. In the case with the Cloud-based version, such dictionary is stored on the WebSpellChecker Servers, and each dictionary is associated with a particular service ID.

As soon as the end-user decides to create a personal user dictionary on the server, all the words from cookies (WSC) or local storage (SCAYT) will be moved to the dictionary on the server accordingly.
