How we build
When an action touches your files, photos, money, or accounts, the product keeps the decision visible, checks what happened, and leaves a way back.
The person reviews and approves the important action.
The product checks and clearly reports the result.
Mistakes have a safe, understandable path back.
Privacy is how we build, not what we sell: data minimization, local processing when practical, and clear deletion are product requirements.
