  3. Privacy-Preserving Notifications/Generic Notification Mode

    Recently, reports involving Signal highlighted that operating system notification databases may retain sensitive information from message notifications, even after the original messages are deleted. While this example involved Signal and iOS, the same general risk may apply to other apps and operating systems where notification content is stored or indexed outside the app.

    For privacy-focused users, Proton Mail and other Proton products should offer an option to use generic notification text instead of exposing message content in system notifications.

    For example, instead of showing sender names, subject lines, or message previews, the notification could simply say:

    “New Proton Mail message…

  4. LA CRM - Mailbridge Failure

    Hi Proton Team,

    This is a niche issue, but I utilize a tool called Less Annoying CRM (LACRM), which allows permits email logging required for my industry. On their help site (https://www.lessannoyingcrm.com/help/finding-imap-information-for-email-syncing), they specifically call out proton mail for being unable to sync with their tools:

    "ProtonMail: their end-to-end encryption prevents a normal IMAP sync. ProtonMail’s “Bridge” tool does not solve this, so automatic email logging will not work."

    Is there the possibility that the bridge tool could permit a normal IMAP sync without compromising the security of the tool?

  5. Time-tracking Calendar Integration

    One missing feature from the Proton Suite is a Time-tracking layer integrated in the Calendar app.

    It would be a handy feature to toogle on/off alongside your planned schedule, in order to track the real time invested in your projects, get records and overviews, and be able to learn from them and improve your workflow. All with the same level of privacy and encryption of the other features.

    Right now Proton users still depend on external apps to track their time, which don't integrate in the Proton ecosystem nor offer the same kind of data security. More on the contrary,…

  6. dark mode toggle in-app

    The mobile apps need to have a dark mode toggle just like the web version. I want to keep my device in light mode but have this app in dark mode just like every other company offers but for some reason it only syncs with your device theme. It exists for the web version so why is it overlooked in the mobile apps?

  7. horizontal calendar mode in mobile app

    In the mobile app (I am using IOS) I cannot turn my phone horizontal on to view the calendar in an extended aspect ratio. This makes the week view nearly impossible to use and limits you to the 3 day view on mobile. It works on the iPad app but not on the iPhone app so this seems to be a hugely overlooked feature.

  8. Share and collaborate on emails.

    There is a wonderful feature in Spark and Bluemail that allows the user to share an email with a pre-approved contact in lieu of forwarding and going back and forth that way. When you share an email with another user, a chat opens up in which the two users can discuss the content of the email without having to forward and comment in a new email. The absence of this feature is the ONLY reason my wife and I haven’t switched to protonmail desktop as our primary email client.

  9. Import Mail Files from Mac OS Mail App

    To make best use of proton mail app I need the chance import my existing mail archives - the files I have created in Mail on my MacStudio). Not being able to have my mail archives accessible renders proton mail meaningless. I cannot work if my old mails are not available in the system.

  10. Calendar delete invitations on iOS

    Invitations can only be responded to in Proton Calendar on iOS. I would like to just delete the invitation from my Calendar altogether, without response.

  11. Block sender without opening the email

    Opening suspicious messages shouldn't be necessary to block the sender, hate doing that.

    A 'block sender' button at the top would be great next to 'move to spam' and 'delete'.

  12. Remove notification after event ends

    In Google Calendar, on Android at least, event notifications automatically disappear after an event ends. It would be nice if Proton Calendar did the same, to help keep the system notification tray tidier.

  13. (Current) Critical Security Vulnerability: Missing Default-Deny Policy - Why Whitelists Fail Against Zero-Click Exploits (State Trojans)

    (Current Text) April 26, 2026
    Dear Proton Team,

    Currently, Proton Mail under (Filters) "Blocked and Allowed Senders Lists" offers only a whitelist as a positive exception in a system that standardly accepts everything ("Default-Allow"). The "Allow" function serves merely to move important emails back from the Spam folder to the Inbox; it does not prevent the receipt of emails from other domains. The "Block" function serves only to block known, malicious senders.

    The fundamental security problem is that for users who need to protect themselves against Zero-Click Exploits (e.g., advanced state trojans like Pegasus or similar spyware), this "Default-Allow" model…

  14. Improve email masking in Daily Notifications (Show first and last characters)

    Currently, Daily Email Notifications only show the first two characters of the recipient address. This makes it difficult to distinguish between similar aliases or folders (e.g., support@... vs super@...).

    I suggest updating the masking logic to show both the beginning and the end of the local part of the email address.
    * Current: su********@proton.me
    * Proposed: su****rt@proton.me or s******t@proton.me

    This provides better clarity while maintaining the privacy of the full address.

  15. Creation of a Public Spam Address List

    I suggest creating a public list of known spam addresses. This list could be initially curated by Proton Mail and then maintained and continuously updated by the community (for example, via GitHub).

    Additionally, it would be highly beneficial to add, in this section (https://account.proton.me/u/78/mail/filters#spam) within each user account’s spam filter settings, a feature that allows users to upload one or more precompiled lists of spam addresses (e.g., in .txt, .md, .csv, .json, or similar formats). This would enable users to manage their own personalized lists and import them all at once, rather than having to mark addresses individually.

  16. Strike agenda items

    When deleting an event in the Proton Calendar, I still want to be reminded that it was there originally. Is it possible to offer two kinds of delete:
    (A) strike through the event (so it is still visible in the calendar, but now the title is in strike through), or
    (B) permanently delete the event?

  17. Option to hide the left sidebar when viewing an email on OSX

    On web, you can simply click a left arrow and it minimizes the sidebar. But you can't do this in the OSX desktop app. Would love increased focus in my experience when reading an individual email, side bar is distracting. Thanks

  18. sunrise and sunset times

    For people who start the day early (runners, photographers etc), it would be really useful to have the option to display sunrise/sunset times for your local area. Planning out hikes/runs etc would be so much easier.

  19. Option to remove previous email history when replying

    sometimes i dont need the existing conversation and its tiresome to remove it each time i reply
    it could be added to settings as an ability to disable quoting the messages we are replying to

  20. Option to be able to click anywhere on email when shift / ctrl clicking

    I know you can select email by pressing the thumbnail and using ctrl-click or shift-click from there to select, but I'd like to have the option to do this without having to press the thumbnail every time.

    Often I end up accidentally clicking away or forgetting and clicking the email itself when selecting and its quite annoying. Or it ending up taking longer to select emails because I have to carefully click each one.

    Worst case please add it as an toggleable setting.
