今天，我们为14亿中国人带来了本地化支持。这是我们为所有人带来互联网隐私和安全的使命中非常重要的一步。 Today, we’re making ProtonMail more accessible for 1.4 billion native Chinese speakers, a major step forward in our mission to bring Internet privacy and security to all. 从现在开始，除了已经支持的14种语言外，您还可以使用简体中文和繁体中文为ProtonMail的默认语言。要更改默认语言，只需要在mail.protonmail.com中登录帐户，选择导航条的”设置（Settings)”，然后在”语言（Language）”下拉菜单中选择您语言即可。 自去年推出的志愿者翻译项目以来，中文本地化一直是ProtonMail的首要任务。这个志愿者计划的目标是翻译ProtonMail静态页面，网页应用界面以及iOS和Android应用程序。ProtonMail已支持捷克语，荷兰语，英语，法语，德语，意大利语，日语，波兰语，葡萄牙语，罗马尼亚语，俄语，西班牙语，土耳其语和乌克兰语。 中国拥有超过7亿的互联网用户，并且在线人数超过世界上任何其他国家。中文也是使用最广泛的语言，其次是西班牙语和英语。繁体中文是香港和台湾人的主要书面文字，简体中文主要用于中国大陆和新加坡。 现在ProtonMail已经覆盖超过30亿人的母语本地化。这要归功于翻译志愿者的支持。非常感谢ProtonMail的社区对翻译工作的帮助。 我们正在积极努力带来更多语言的本地化。如果目前ProtonMail不支持您的母语，我们邀请您并希望您能加入翻译项目。访问此页面了解更多详情。 诚挚的问候， ProtonMail团队
