> All data is in my phone

It's stored in your phone but it's still going to the LLM when working on it, right?

Unless you invented a system of magic placeholders?

I trust Gemini API because they already have all my data and in Openrouter I have only enabled providers with Zero Data Retention and that are not using prompts for training (you can check Openrouter docs for this).

As you can imagine the official Deepseek API doesn't honor these conditions but there are US based provider like Novita, Coreweave... that serve this specific Deepsek model and honor them.
