Proton said the Standard Notes app, which is available for both mobile and desktop, will remain “open source, freely available and fully supported”.
It also suggested that there will be no change to Standard Notes’ prices; its press release specifies that existing five-year subscriptions “will continue to be honored.”
“Standard Notes will remain an independent product and in due course both companies will open access to their products to each others’ users,” Proton added.
It’s a bit murkier, SimpleLogin remains an independent product that you can now login to with a proton account. They also added some of SimpleLogin’s features into Proton.
I wouldn’t be surprised if they do a similar thing where you can login to standard notes itself with a Proton account but they also start integrating pieces of the app more closely into the Proton suite.
