free cloud data stores that use get/post? [closed]

Question

I know that there are other key/value stores similar to http://openkeyval.org out there but i cannot remember their names.

Please enlighten me.

i need the following features:

• free
• can be used via 100% clientside code
• fast and easy to integrate with

edit:
dropped the security requirement, since its not very important to me and was skewing the answers towards self-hosted solutions.

found another service:
http://rastajs.errorjs.com/

this one is easy to use but seems to mangle my values by removing all the spaces!

Parse.com's data storage api has a really wonderful jquery library ( https://github.com/srhyne/jQuery-Parse ) that makes it extremely easy to have simple key/value storage from your front-end javascript.
