Hi Proton Team and Community,

first of all, thank you for creating Lumo — a privacy-first AI assistant that finally allows European users and businesses to use AI without compromising confidentiality or GDPR compliance. Proton has solved the fundamental problem that all other AI platforms struggle with: trust.

Now that Lumo exists, I would like to propose the next major step:

➡️ A Private Lumo App Store for creating, sharing, and monetizing custom “MyLumos”.

Just like OpenAI has custom GPTs (and a GPT Store), Proton could offer a secure and encrypted alternative — fully compliant, private, and built inside the Proton ecosystem.

1. What this feature would enable

Users could create their own AI assistants (“MyLumos”) — for example:

• productivity assistants
• privacy-focused advisors
• business workflow helpers
• educational bots
• interactive story or game bots
• niche expert assistants in specific fields

…and then share them securely with:

• the entire Proton community,
• selected groups,
• teams within a business,
• or even privately via Proton Drive.

All without leaving the Proton environment and without any data ever going to third parties.

This would be the first truly GDPR-compliant AI app ecosystem, something no US-based provider can offer today.

2. Why Proton is the perfect place for this

Other platforms store user chats on US servers, often unencrypted, often used for training, and not protected against government access. This makes serious use cases (business, legal, financial, medical) impossible.

Lumo is already the solution:

• End-to-end encrypted
• No server-side logs
• Not used for model training
• Runs in EU-based infrastructure
• Built by a privacy-focused, community-funded organization

A Lumo App Store would expand this into a full secure AI ecosystem for Europe.

3. Monetization (optional for creators)

To motivate creators and allow quality apps to thrive, Proton could offer:

Option A: Ad-supported free usage

Creators can enable a small, privacy-friendly ad banner (no tracking, no profiling).
Revenue is shared between Proton and the creator.

Option B: Remove ads

Users can pay a small one-time fee or subscription to unlock ad-free usage.
Pricing is set by the creator.

This creates a win-win-win situation:

• Proton receives sustainable income (without surveillance)
• Creators are rewarded for their work
• Users can choose between free or premium

All inside a privacy-respecting system.

4. Why this matters

This would give Europe its first:

• privacy-first AI marketplace
• GDPR-compliant platform for business AI
• safe space for sharing creative and educational AI tools
• secure alternative to OpenAI’s GPT Store
• environment where users don’t have to fear data extraction or third-party access

As a creator myself (building tools like interactive privacy games and business assistants), I would immediately move everything to Proton Lumo if such a store existed — especially for sensitive applications that cannot run on OpenAI for compliance reasons.

---

5. Final statement

A private Lumo Store would make Proton the leading AI platform for privacy-conscious users, European companies, and creators. It would fill the gap where all other AI platforms fail:
Privacy, compliance, trust, and transparency.

I truly believe this could become one of Proton’s most impactful innovations — and I would love to support and contribute to it.

Thank you for considering this idea!
Proton + Lumo + Community = 🚀
