I came across “PrivacyNotes” by accident when looking for something else on Caskhub. I am not sure if this is the proper place to submit apps or websites for consideration to be recommended. They claim to have E2EE, zero knowledge, open source, no subscription, hosted outside the US, and more. That was paraphrased from their website. I have not had a chance to try their service \ myself. I also am not able to examine their code because that is not something I have knowledge in but it is on github.
If this isn’t the correct location for submitting software/apps to be considered. Let me know and I’ll repost in the proper area.
