Title: Integrate Green Contextual Advertising to Expand Lumo Free Tier

Description:

Problem: Lumo's subscription-only model limits free tier generosity (7-day chat history, 100 queries/week), restricting adoption to a privacy-conscious niche rather than building the mass user base needed to challenge US AI dominance.

Proposal: Implement "Lumo Green Ads" — contextual advertising from EU-certified green companies, using the EU's September 2026 Empowering Consumers for the Green Transition Directive (Directive 2024/825/EU) as regulatory foundation.

Benefits:

Enables expanded free tier (300-500 queries/week, 30-90 day history) for users opting into ads
Preserves privacy principles: no behavioral tracking, no profiling, on-device content classification only
Creates competitive differentiation that US competitors cannot credibly match
Aligns with EU policy coherence (Green Deal + Digital Strategy + AI Act)
Generates supplementary revenue while expanding accessibility to broader user base
Technical Feasibility: Privacy-preserving contextual advertising frameworks already exist (TCF 2.2 compliance, on-device keyword extraction, TEE-based processing). No third-party tracking, cookies, or cross-site profiling required.

Model: Contextual, not behavioral. Ads matched to query content. Certified advertisers only (ISO 14067 or EU Ecolabel required). User opts in for expanded free tier; opt-out preserves current experience.

Implementation: Phased rollout — pilot with 10-20 certified advertisers in Germany/Netherlands (strong green consumerism markets), expand to 100+ across EU within 12 months.

Revenue Estimate: At €3-8 CPM for contextual green ads with 2-5M free users, generates supplementary income to subsidize expanded free tier features.

Strategic Significance: Addresses core tension between values-driven positioning and growth imperatives needed for geopolitical influence. The September 2026 directive enforcement creates a first-mover window before US competitors can adapt.
