''Is Tiddlyspot secure?''
No. Tiddlyspot does not use SSL/https. Your password is sent in clear text when uploading and when authenticating to access a private site. This means that your Tiddlyspot is vulnerable to packet sniffing and your password could be discovered by a malicious third party. Also your data is transmitted unencrypted when you view your site, even if it is a private site. For this reason please don't put sensitive information such as banking details in your Tiddlyspot and don't use a password that you use for other high security sites.
