teknik.io is a website that provides services like email, [encrypted] file uploads, Git repos, blogs, URL shortening, and more. I've used them for a few years and they're wonderful. It's all open-source and privacy conscious, maybe some Tildes users would like it?

Registration is usually invite-only, but it's open for a few hours.

Thanks @duckoverflow for mentioning this.

Edit: also their privacy policy is short, simple, and easy-to-read if anyone is interested in that. I'd consider it a great example of what a privacy policy should be.
