1. Proposal: Two Self-Hosted Media Side Projects for the Proton Ecosystem

   Hey everyone,
   I’d like to propose two side projects that Proton could develop. Both concepts are self-hosted media streaming services that would add massive value to the Proton ecosystem without requiring Proton to build or maintain new data centers.

   1. ProtonTV: Self-Hosted Video Streaming
      ProtonTV would be a media server and client app allowing users to stream their personal video libraries (e.g., ripped DVDs, Blu-rays, or other downloaded media).
      How it works:

      • Self-Hosted: Install it on a NAS or Home Server.
      • Proton Drive Integration: Alternatively, download the app on any device, log into your Proton account, and link a Proton Drive folder containing your media. To save server costs, the client device’s resources would handle processing tasks like decoding and series identification.
      • Metadata: The app would use TMDB as the default scraper, with options to add third-party database extensions. Subscription Tiers:
      • Free Tier: Host it on your Home Server (limited to local network access by default, as most users watch series and movies at home). However, users still have the option to set up remote access manually via port forwarding or tools like Tailscale.
      • Plus Tier (e.g., Mail Plus, Drive Plus, VPN Plus): Unlocks official, seamless remote access to your Home Server through your Proton account, OR unlocks the Proton Drive linking method.
      • Bundled Tier (e.g., Proton Unlimited, Duo, Family, Visionary): Unlocks remote access + Advanced Media Features. The app scans your .mkv (and other) files for embedded dubs and subs, lets you set default language profiles, and automatically fetches missing dubs and subtitles from the internet.

   2. Protonfy: Self-Hosted Audio Streaming
      Protonfy would be the audio equivalent—a self-hosted music streaming service for your personal song library.
      How it works:

      • Self-Hosted: Like ProtonTV, it can be installed on a NAS or Home Server for local file management.
      • Proton Drive Integration: Users can also choose to stream their library directly via a linked Proton Drive folder. Subscription Tiers:
      • Free Tier: Self-host the service on your Home Server or NAS with remote access included out-of-the-box (since music is primarily enjoyed on the go, making local-only access impractical).
      • Plus Tier: Unlocks the ability to stream your library directly from Proton Drive.
      • Bundled Tier: Adds an automated feature that downloads lyrics for your library from free online databases.

   Future Vision: The "Plex Hybrid" Model

   If Proton ever decides to enter the licensed media space, both apps could evolve into a hybrid model similar to Plex. Users could choose to prioritize their local, self-hosted files or seamlessly integrate Proton's licensed content.
   For now, keeping these projects strictly self-hosted allows Proton to build them as low-maintenance side projects in their free time, keeping the main focus on their core privacy apps.

2. Geburtstag im Format dd. MMM eingeben (ohne Jahr)

   In Kontakte (Proton Mail) sollte es möglich sein, den Geburtstag einer Person ohne das Geburtsjahr einzutragen. Dies ist aktuell nicht möglich. Ich kann den Geburtstag nur als dd. MMM yyyy eingeben. Dies ist ein Problem, da ich so das Geburtsdatum nicht eintragen kann, wenn ich das Geburtsjahr nicht kenne und kein fiktives Geburtsjahr "erfinden" will.

3. Fowarding Mails from Gmail contradicts the reason why I switched to Proton.

   I want to do everything I can to get more free storage space. However, the forwarding from Gmail to Proton means that the systems from Google know my new email addresses. I prefer to manually switch my accounts to the new email addresses.

4. Help us get ready for youtube vpn blocks

   I just had my first experience on youtube (app, have not graduated to using it on Brave browser) where it showed me results for my search (biatholon athlete's name who competes internationally) and refused to allow me to use it unless I turned off vpn. I did a little searching and saw it's been an issue for 5 months or so, possibly related to the UK ID checking nonsense. While I'm seriously thinking about deleting youtube too many institutions require using it to view content that they require. I switched to another server and cleared the cash on the proton vpn and youtube. I can watch videos it shows me, I'm just anticipating a day when it will block all use with a vpn. I suggest in-depth blog post(s) on bypassing this with vpn settings, other ways, and getting youtube type content elsewhere (not another ****** platform that grabs as much data as it can and designs itself to be addictive).

   Sorry this is not a request for functionality.

5. No US social media platforms for news, discussions, etc.

   I would appreciate it if feature releases, the latest news on privacy and tips on online security were not announced and discussed on US platforms such as X and Reddit. These are private-sector platforms, and the US administration is using its economic and military power to prevent regulations on American social media platforms that would protect EU European users.

7. Data validation in Proton Sheets

   Hello Proton Team,

   So the current behaviour of the validation is that when we press a "Delete" on a validation Cell, the validation Cell with "Dropdown (from a range)" will entirely disappear, which is quite wrong in my opinion. I (and I believe the most people) would be expected that deletion won't remove the validation that applied on that Cell.

   Not just this, I hope this validation system can have an option that allows user to decide rejecting the value or not, with the rule we set up. Unlike the current status that always allow other values that is not following the validation rule.

   Sincerely,
   sia

8. Has proton ever considered joining forces with GrapheneOS?

   This would be a real game changer in the market. A one stop shop for all my security concerns. Add in good virus software and Graphene/Proton would be a powerhouse.

9. Please consider joining the Fediverse

   Mastodon is way better place to have a converstation than this forum that forces me to share feedback by logging in through Facebook or Google, whilst my name and IP address is getting permanently stored.

10. I would like to advise Proton to think long and hard about the setup of this forum

    As a European Proton customer I would like to advice Proton to think long and hard about the setup of this forum.

    I just had sign away the storing of my name, ip adress and other things just to provide feedback to Proton.

    And I had to gain access to the forum through Facebook or Google.

    Really, in this day and age?!?

11. Prioritization

    Hi Proton Team!

    I really like all the new products and ideas that are implemented. I appreciate how this is mostly due to people in this forum actively requesting stuff and you listening! Bravo.

    BUT! Could you please mainly focus on the boring task of improving your existing products before rolling out new stuff? There are so many important features being discussed here that are just sitting and waiting since 2023...For example:

    • Mac Folder Sync
    • Separated Mailboxes
    • Improved Docs

    I understand the excitement of launching new products, but a solid foundation matters more than a wide product range. Quality over quantity, please!

    Thanks for listening.

12. excel

    Awesome to see sheets coming to Proton. Some things I noticed that were missing for me when using Google Sheets:

    1. When using the '$' symbol, I'm noticing the cells still move if dragging or copying. Generally this symbol indicates that the cells should be static.

    2. When using the "sum" feature and I add a row in the middle, the "sum" should update to include the new total number of rows.

    3. The ability to "hide" a sheet that I don't want to see all the time.

    4. Suggestion: for the "accounting" formatting, can we move the currency symbol to always be left aligned and the numbers to be right aligned? Google sheets does this with their formatting and I really prefer it when viewing money.

13. Proton Sheets - Undo via keyboard shortcut inconsistent

    On Mac within safari, using cmd+Z to undo within Proton Sheets sometimes undoes the last action in sheets as it should, or it randomly switches to undoing within safari (reopening a closed tab).

    unclear to me when it choses to do which, but it's very disorienting.

14. Proton sheets - backspace or change of a cell should not lose formatting + formula weirdness

    I have a column of dates. If I change one, the formatting of the cell reverts to black text even though I changed it to white.

    I also have a row of cells that are dark with white text. if I hit backspace on the cell (ie getting rid of the text) the cell loses its background colour.

    I've tried recreating one of my google sheets in proton sheets, but I haven't managed to get very far. Having to continually reformat things is tedious. I knew that functionality would be basic initially, but this is a simple duration counter (for tracking birthdays/ages).

    also...
    The formula don't work the same?

    have a few cells set up as follows:
    =DATEDIF(A4,T2,"Y")
    =DATEDIF(A4,T2,"YM")
    =DATEDIF(A4,T2,"MD")

    (where A4 is the "start" date and T2 is today's date.)
    this spits out the years/months/days between those two dates.

    But when I refer to those like so:
    =D4&" is "&Q4&" years, "&R4&" months, "&S4&" days old."
    (D4 being the name of the person)

    it SHOULD say
    Name is x years, x months, and x days old

    what it does instead is:
    Name is 35 years, 11 months, 17.10994212962963 days old.

    Yet the day cell had no decimal points, it was simply 17. Google sheets treats this as an integer, too.

    EDIT:

    I noticed this is because I used
    =NOW()
    like I did in google, but here I should have used
    =TODAY()

    changing that fixed the creation of a crazy long fraction. I sort of understand the logic to this, but I feel like being able to port across from google sheets logic would be beneficial.

    EDIT 2: also, if someone specifically set up a cell with, say, two decimal points visually showing despite actually being a much longer number, and then wanted to refer to that cell as part of a string like I have--- that would simply override that preference.

    DE: [Seu Nome / Coletivo de Usuários de Privacidade]
    ASSUNTO: Proposta de Aprimoramento Crítico: Criptografia Total de Metadados no Ecossistema Proton (VPN + Mail)
    DATA: [Data Atual]
    PRIORIDADE: Estratégica & Técnica

    ---

    1. INTRODUÇÃO E CONTEXTO URGENTE

    Prezada Equipe Proton,

    A Proton AG consolidou-se como farol global em privacidade digital, oferecendo serviços confiáveis como Proton Mail e Proton VPN, que priorizam a criptografia de conteúdo e tráfego. No entanto, uma vulnerabilidade crítica persiste – e sua solução definirá o próximo patamar da privacidade verdadeira: a proteção integral dos metadados.

    Metadados são a “assinatura comportamental” do usuário: horários de conexão, localização aparente, padrões de comunicação, relações de endereço de e-mail, tamanho de mensagens, e até padrões de tráfego de rede. Esses dados, quando expostos, permitem:

    · Perfis de vigilância massiva (como revelado por Edward Snowden).
    · Identificação de usuários mesmo com conteúdo criptografado.
    · Correlação de atividades entre serviços, destruindo o anonimato.

    Atualmente, nem Proton Mail nem Proton VPN oferecem criptografia sistemática de metadados como funcionalidade padrão ou avançada. Esta é uma lacuna estratégica e de segurança que pode ser preenchida com inovação técnica.

    ---

    1. VISÃO PROPOSTA: METADATA-SHIELD™ (OU “PROTON GUARD”)

    Sugerimos o desenvolvimento de um sistema unificado de criptografia de metadados, aplicado tanto ao Proton Mail quanto ao Proton VPN, com as seguintes premissas:

    · Criptografia de metadados de ponta a ponta (E2EE para metadados).
    · Ofuscação ativa contra análise de tráfego (traffic analysis).
    · Integração transparente com os protocolos existentes.
    · Modos de operação configuráveis (equilíbrio entre privacidade extrema e desempenho).

    ---

    1. PROPOSTA TÉCNICA DETALHADA

    A) Proton VPN – Metadados de Conexão e Tráfego

    Vulnerabilidade Atual Solução Proposta
    IP real pode ser inferido por timing attacks ou vazamentos de DNS. Modo “Full Metadata Obfuscation”: uso de redes overlay como Tor sobre VPN (opcional) e padding de pacotes aleatório.
    Padrão de tráfego identifica atividades (ex.: streaming vs. mensagens). Traffic Shaping Adaptativo: injeta tráfego falso e uniformiza tamanho de pacotes.
    Timestamps de conexão expõem hábitos. Delay Jitter Aleatório: introduz atrasos não determinísticos nas sessões.
    Servidor VPN conhecido pode ser correlacionado. Multi-Hop Dinâmico: roteamento automático entre 2–3 servidores Proton com criptografia em camadas.

    B) Proton Mail – Metadados de E-mail

    Vulnerabilidade Atual Solução Proposta
    Assunto, remetente, destinatário em texto plano (fora do corpo criptografado). Criptografia de Cabeçalhos PGP-Extended: estender o padrão PGP para incluir metadados essenciais no bloco criptografado.
    Relações sociais expostas pela lista de contatos. Contact Graph Encryption: armazenar contatos localmente ou criptografados com chave derivada do usuário.
    Timestamps e tamanhos de e-mail. Agregação Temporal: enviar e-mails em “lotes” horários predefinidos pelo usuário.
    Notificações push que vazam existência de novos e-mails. Modo “Stealth Notifications”: notificações genéricas sem indicar origem ou quantidade.

    ---

    1. ARQUITETURA SUGERIDA – SISTEMA DE METADADOS CIFRADOS

    Camada 1: Criptografia de Conteúdo (já existente)
        - Mail: AES-256 + PGP
        - VPN: AES-256-GCM / ChaCha20
    
    Camada 2: Criptografia de Metadados (nova)
        - Mail: Encapsulamento de cabeçalhos em bloco E2EE
        - VPN: Envelope de metadados de sessão criptografado com chave episódica
    
    Camada 3: Ofuscação de Padrões (nova)
        - Mail: Padding de tamanho de e-mails + agendamento estocástico
        - VPN: Traffic masking e multi-hop aleatório
    
    Camada 4: Controle do Usuário
        - Interface “Privacy Slider”: configuração granular (Modo Normal > Avançado > Paranóico)
    

    ---

    1. BENEFÍCIOS ESTRATÉGICOS PARA A PROTON AG

    · Diferencial absoluto no mercado: Primeiro ecossistema com criptografia integral de metadados.
    · Atração de usuários de alto risco: Jornalistas, ativistas, dissidentes, corporações com demandas de compliance extremo.
    · Preparação para regulamentações futuras: Leis como GDPR 2.0 e ePrivacy tratarão metadados como dados pessoais.
    · Fortalecimento da marca: “Proton – Where Metadata Also Dies.”

    Para: Equipe de Desenvolvimento e Liderança da Proton AG
    Assunto: Sugestão para Implementação de Criptografia de Metadados no Proton Mail e Proton VPN

    Prezada Equipe Proton,

    Como usuário comprometido com privacidade digital e admirador do ecossistema Proton, gostaria de sugerir uma melhoria que considero fundamental para alinhar ainda mais seus serviços com os princípios de privacidade por design: a criptografia completa de metadados no Proton Mail e Proton VPN.

    🛡️ Contexto e Oportunidade

    Atualmente, o Proton Mail já oferece criptografia de ponta a ponta para o conteúdo de e-mails, e o Proton VPN protege o tráfego com protocolos modernos. No entanto, metadados (como assunto, remetente, destinatário, horários, geolocalização de conexão, etc.) permanecem parcialmente expostos ou associáveis em determinados cenários.

    A criptografia de metadados representaria um salto evolutivo, posicionando a Proton como a primeira plataforma unificada a oferecer privacidade integral — não apenas para dados, mas também para o contexto das comunicações.

    💡 Benefícios Estratégicos

    1. Diferencial competitivo absoluto: · Nenhum outro ecossistema (Tuta, ExpressVPN, etc.) oferece VPN + e-mail com criptografia total de metadados de forma integrada. · Atrairia usuários de alta sensibilidade (jornalistas, ativistas, empresas com compliance rigoroso).
    2. Alinhamento com a missão Proton: · Consistente com o lema "Privacy by Default". · Reforçaria a confiança na marca como líder em privacidade real, não apenas em marketing.
    3. Preparação para regulamentações futuras: · Leis como GDPR e DMA estão aumentando a pressão sobre proteção de dados; metadados são cada vez mais tratados como dados pessoais. · Oferecer essa proteção antecipadamente colocaria a Proton à frente de requisitos legais.

    🔧 Sugestão de Implementação Técnica

    · Proton Mail:
    · Criptografar assunto, cabeçalhos e relações de endereços com chaves derivadas das chaves PGP dos usuários.
    · Oferecer opção de modo "Metadados Ocultos" (similar ao funcionamento do Tuta, mas com a robustez do PGP e criptografia pós-quântica em desenvolvimento). AES - 256 Bits e AES - 512 Bits
    · Proton VPN:
    · Implementar ofuscação avançada de metadados de conexão (timestamp, padrão de tráfego, portas).
    · Explorar técnicas como padding de pacotes e delay-jitter aleatório para reduzir identificação por análise de tráfego.
    · Integração Proton Ecosystem:
    · Sincronizar chaves de criptografia de metadados entre Mail, VPN, Calendar e Drive para uma experiência unificada e sem vazamento contextual.

    🌍 Impacto Esperado

    · Para usuários: Privacidade verdadeiramente abrangente, reduzindo riscos de inferência de comportamento, profiling e vigilância baseada em metadados.
    · Para a Proton: Consolidação como o ecossistema mais seguro do mundo, justificando premium pricing e fidelização a longo prazo.
    · Para a indústria: Estabelecimento de um novo padrão ético em privacidade digital.

    ⏳ Considerações de Viabilidade

    · Reconheço os desafios técnicos: impacto na performance, usabilidade e interoperabilidade (especialmente com e-mails externos).
    · Sugiro uma abordagem faseada:
    1. Lançar como recurso opt-in para usuários avançados.
    2. Coletar métricas de desempenho e feedback.
    3. Evoluir para default progressivamente.

    🎯 Conclusão

    A Proton já é referência em criptografia e privacidade. Criptografar metadados seria o próximo marco natural — um movimento ousado que redefiniria o que significa "comunicação segura" e solidificaria o legado da Proton como pioneira em privacidade digital real.

    Agradeço pela atenção e permaneço à disposição para contribuir com testes ou discussões técnicas.

    Respeitosamente,
    [Seu Nome ou "Um Usuário Comprometido com a Privacidade"]

20. What could be improved in Proton so that more people would buy subscriptions?

    1. Proton pay - I use GrapheneOS, and I'm missing software that can replace Gpay, that I can trust with my data, and that I want to use with NFC.

    2. Proton notes - Right now, I'm using Notesnook. Obsidian seems too cluttered for me, while Notesnook looks minimalistic. I use to-do lists and tables, because it's convenient for me to have everything in one app, but maybe in the future I'll start making tables in Proton Sheets.

    3. Proton to-do-list -In Notesnook, I have tables, notes, to-do lists, all of which are missing from the Proton app. At least the to-do list and notes are there, and you can switch to tables in Proton Sheets, but I haven't seen the need for that yet.

    4. Proton forms

    5. Proton RSS Reader - I use the minimalist BazQux Reader, but I would like a confidential one from Proton.

    6. More support for Linux, because there are more people in Linux who care about security and privacy.

    I believe that these innovations will make Proton much more popular and many people may switch to Proton, while others will purchase more expensive subscriptions.
