Thanks for the suggestions guys. I have decided to go with Aegisub for the time being, the reason being that I want to retain my own intellectual property. Also, given the propriety nature of the subjects I work on, I don't think my clients would agree to me using an online platform.
Subtitle Edit is not an online platform, so it's safe to use without causing any confidentiality problems. I used Aegisub but found it cumbersome so gave it up. There is also MonalLe which I've used and is not an online platform, so it's safe too, especially in your case.
