From Mac360’s review of Evernote, and from my It Pays To Read The Fine Print department comes the Terms of Service agreement at Evernote:
Accordingly, by using the Service and posting Content, you grant Evernote a license to display, perform and distribute your Content, and to modify and reproduce such Content to enable Evernote to operate and promote the Service. (You also agree that Evernote has the right to elect not to accept, post, store, display, publish or transmit any Content in our sole discretion.) You agree that these licenses are royalty free, irrevocable and worldwide, and include a right for Evernote to make such Content available to others with whom Evernote has contractual relationships related to the provision of the Evernote Service, solely for the purpose of providing such services, and to otherwise permit access to your Content to third parties if Evernote determines such access is necessary to comply with its legal obligations.
In other words, when you store your data online using Evernote, they can re-distribute or modify your data any which way and wherever they choose. They wouldn’t, would they?
