Long time ago, about 10 years ago, I thought of similar contraption with already google-verse system. Basically you upload a encrypted file (text or pdf) to google drive with public share link, and add an event to your Google calendar with a 3 month advance notice (& 2 months, 1 months, all by email), one time recurring only.
