@XNHQ@mastodon.social End-to-end privacy and zero-knowledge principles: Proton emphasizes zero-access encryption and data that cannot be accessed by third parties, including during AI interactions, with chats and data decrypted only on user devices and not logged or sent to external AI providers when users choose private options. On-device and open-source approaches: Proton highlights on-device indexing and the use of open-source language models for some AI tasks, which enhances transparency and reduces reliance on external data collection by third parties https://techcrunch.com/2025/07/23/protons-new-privacy-first-ai-assistant-encrypts-all-chats-keeps-no-logs/ No data retention for AI processing: In Proton Scribe’s privacy-first implementation, prompts transmitted to servers are minimal, and data is not retained after the draft is created, reducing exposure to training data or third-party access. https://techcrunch.com/2024/07/18/proton-launches-privacy-first-ai-writing-assistant-for-email-that-runs-on-device/ 1/2

@XNHQ@mastodon.social 2/2 Independent privacy design: Proton positions its AI work as privacy-first, often away from large open data-train partnerships (e.g., not sending user data to third-party providers like OpenAI) and focusing on internal models and European-hosted infrastructure to improve privacy protections. https://proton.me/blog/proton-scribe-writing-assistant Use Proton Drive and other privacy-centric services as part of an integrated privacy strategy, since Proton argues these layers minimize exposure to AI training or data harvesting https://proton.me/blog/proton-scribe-writing-assistant No one forces you to use either Lumo or their assistant, which can be deactivated. Proton Scribe (the Proton Scribe writing assistant) can be deactivated. You can turn it off in your Proton settings so it’s hidden from the email composer, and admins can control access for users as needed. If you want, https://proton.me/support/proton-scribe-writing-assistant#disable 🤷 🤷 🤷 🤷
