I would like to suggest adding Bulgarian language support across all Proton apps and services, including Proton Mail, Proton Drive, Proton VPN, Proton Pass, Proton Calendar, and the Proton web interface.

Bulgarian is spoken by millions of people worldwide and is an official language of the European Union. Adding Bulgarian would make Proton’s privacy-focused ecosystem more accessible to Bulgarian-speaking users and would further support Proton’s goal of making privacy available to everyone.

Ideally, Bulgarian localization would cover the entire user interface, including menus, settings, notifications, system messages, onboarding screens, help pages, and other user-facing content.

It would also be great if Proton could consider allowing the community to contribute to or review Bulgarian translations, as community localization can help ensure that translations are natural, accurate, and consistent.

I hope Proton will consider adding Bulgarian in the future. It would be a very welcome improvement for Bulgarian-speaking users.
