Proton Calendar prices by country, on its own site
We read Proton Calendar’s pricing page on proton.me from 8 countries on Oct 9, 2026. It showed the same prices in every one of them as in the United States.
Read by a script, from a home connection in one country and from a data centre in each of the others. A site does not always show a data centre what it shows a person at home there. A page can list its prices in a different order from one country to the next, so a price here is not matched to a plan: open the vendor’s page to see which is which. A country’s price is for people who live there.
