I created https://titanotes.com, an online tool/service to encrypt and store text data using a set of keys known only to the sender. The sender then shares the message URL and keys with the intended recipient via a different channel. Messages are stored for 72hrs before being automatically deleted. No client-side information (browser fingerprints, IP address, user-agents etc) is collected. So far, it has processed just over 2k messages in 3 months.

Why did I create it? I suddenly had a lot of time after leaving an exhausting corporate role. Is it perfect? No. A couple of things could be done better/differently.

The future? Knowing that text-only data is limiting, I'm working on: -encrypting attachments - images, PDFs etc. -customizable retention periods

Yes, I know there are existing products serving the same purpose but hey, why not?
