Frequently Asked Questions Is Frontière GDPR-compliant? Yes on every model labeled EU sovereign. Those run on providers with no non-EU capital control, so no US court order can reach your prompts. What does "EU sovereign" mean? It follows the SecNumCloud principle: what matters is who controls the company operating the servers, not where they sit. A US provider with an EU region is still subject to the CLOUD Act. Does Frontière keep my prompts? Not for API calls. Only billing data is stored: model, token counts, and amount charged. The provider does see the content, which is why every model carries its jurisdiction label. How much does it cost? No subscription. You top up a prepaid balance from €10 and pay per token. The cheapest sovereign model starts at €0.0056 per 100,000 input tokens.
