Does Sim train AI on your data?
We don't reduce this to a yes/no — wording matters (defaults, opt-outs, enterprise carve-outs). Here is exactly what Sim's privacy policy said when we captured it on 2026-11-01:
“Generalized AI/ML Model means an AI or machine-learning model intended to be broadly trained across multiple users and not specific to a single user's data or behavior.”
“This data cannot be tied back to individual users and is not used for generalized AI/ML training with Google Data.”
“We affirm that: Sim does not use, transfer, or allow Google Data to be used to train, improve, or develop generalized or non-personalized AI/ML models.”
