A simple web page for users to delete their PeriodTracker account. Use this repo as a template to create your own 'delete account' repository and webpage.
Change the value in config.js to point to your own API endpoint.
You can host this page on GitHub pages or any other static hosting service.
For github pages, go to Settings > Code and automation > Pages. Select the branch to use and the root folder, then add your subdomain, eg delete-account.example.com.
Add a CNAME record to your DNS provider to point to your github pages domain: <user>.github.io.
