Does Vivaldi train on your data?
Vivaldi's browser privacy policy is short and direct, and it does not mention AI, machine learning or model training at all.
At around 5,000 characters this is one of the shortest policies on the site, and it spends them on what Vivaldi does not collect. It contains no form of "train", no "machine learning", no "artificial intelligence" and no bare "AI". Its single "automated" is unrelated to model building. Brevity is not evasion, but it is not an answer either.

How to opt out of Vivaldi AI training
Plan by plan, from what Vivaldi's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.
All accounts
Not graded, so no route is pointed at. At around 5,000 characters this is one of the shortest policies on the site, and it spends them on what Vivaldi does not collect. It contains no form of "train", no "machine learning", no "artificial intelligence" and no bare "AI". Its single "automated" is unrelated to model building. Brevity is not evasion, but it is not an answer either.
