Can you guarantee that you are handling data the way that ProtonMail does? Do you know how ProtonMail handles its data? A privacy policy is not just some mumbo-jumbo where you just need to get the words right. The words need to be in correspondence with your actions. Copying someone else's words is not a recipe for success because those words are in accordance with their actions. Even if the privacy policy is compliant for them, the same policy can be non-compliant for you.
