NOTE: This article is not about any of the “normal” topics of this newsletter: genealogy, history, current affairs, DNA, and related topics. However, I believe that all computer users and owners should be aware of the privacy concerns and the solutions that are available.
Proton appears to be the leading privacy-focused application (Proton Mail, Proton VPN, Proton Drive, and Proton Calendar) available today. Best of all, these applications are available free of charge, although payment is requested for enhanced versions offering additional features.

According to a new announcement from Proton, the following additions have just been made to Proton Calendar:
Proton Calendar, which claims to be the “world’s only” calendar using end-to-end encryption and cryptographic verification, has arrived on iOS, giving those seeking a more secure work suite an alternative to Google, Apple, and the like.
Proton Calendar is pitched as offering encryption for all event details, as well as “high-performance elliptic curve cryptography (ECC Curve25519)” to lock it. The web app version of Proton Calendar is open source, with the code for mobile apps to come next, Proton says. Proton also notes that it never finds out who you’ve invited to an event, and it allows for inviting people outside the Proton ecosystem, letting people “cryptographically verify that it was you who invited them.”
Andy Yen, CEO of Proton, said in an interview with Wired in May that calendars are an “extremely sensitive” record of your life and that protecting them is essential. Encryption protects your calendar data from government requests, data leaks, or “a change in business model of your cloud provider.”
Proton, then, is offering a far more simple pitch: your data is always encrypted, and it’s not being used to connect other (often ad-driven) services or, as is often the case, round out a heap of user data.
Getting a calendar app onto iOS is part of Proton’s broader push to position its suite of services—email, calendar, file storage, and VPN—as a security and privacy-minded alternative to the free (or freemium) ecosystems run by the biggest tech firms. You pay for all but the most basic services, and you get services focused on protecting your work and communications. Proton’s services are not nearly as feature-packed as the more established suites from Google, Apple, or enterprise firms, but they are under active development.
Proton touts its servers and user data as being protected by “Swiss data privacy laws,” which somewhat came back on the company last year. Proton (then known as ProtonMail) had said that it did not, by default, “keep any IP logs which can be linked to your anonymous email account.” After a Swiss court injunction, Proton was forced to keep IP logs on an account under investigation, removed the logging language from its policy, and pointed to Tor as a way to better anonymize Proton access.
