Deleting your ProtonMail account on an Android device requires careful steps to prevent data loss. Before initiating the deletion process, it is essential to back up important emails, attachments, and contact details, as ProtonMail follows strict privacy policies that make account recovery impossible after deletion. Since ProtonMail does not provide an automatic export feature, you will need to manually save emails as PDFs, download necessary attachments, and take note of essential contacts to ensure you do not lose valuable information permanently.

To start the deletion process, open the ProtonMail app on your Android device and log in to your account. Tap the menu icon (three horizontal lines) in the top-left corner and navigate to Settings. Under the Account & Subscription section, find the Delete Account option. Before proceeding, ProtonMail will ask you to confirm your identity by entering your account password. If you have enabled two-factor authentication (2FA), you will also need to input the verification code sent to your registered device. Additionally, ProtonMail may ask you to provide a reason for deleting your account, though this step is optional.

After verifying your credentials, ProtonMail will display a final warning regarding the permanent deletion of your account. If you are sure about your decision, tap on Delete Account Permanently to complete the process. Once deleted, all your emails, contacts, and account settings will be erased permanently, and you will not be able to reuse the same email address in the future. If you decide to use ProtonMail again, you will need to create a new account with a different email address.

If you are hesitant about permanently deleting your account, you may consider alternative solutions such as switching to a free plan or disabling email notifications instead of complete account removal. Additionally, if you plan to transition to another email provider, setting up email forwarding before deletion can help ensure that you do not miss any important messages. By following these steps and taking necessary precautions, you can successfully delete your ProtonMail account on Android while safeguarding any essential data.
