Incident #92022A · 14 SEP 2026major
Bolt.new may train AI and license datasets from user content unless users opt out
The new policy lets StackBlitz use Bolt prompts, code, outputs and interaction data to train AI models and license de-identified datasets to third parties, for compensation, unless the user opts out. Bolt Forge users consent to this as a condition of use, with a stated data value of about $6.50 per month. Accounts in the EEA, UK and Switzerland are excluded, and StackBlitz-only use is not covered.
Taken from you
- Bolt content (prompts, code, outputs, fix traces) can be used to train AI models by default unless you opt out
- De-identified datasets from your Bolt content may be licensed to third-party AI developers, including for compensation
- Forge users must accept training and dataset licensing as a condition of using Forge; the opt-out does not apply while Forge is enabled
- Opt-out or withdrawal does not undo models already trained or datasets already delivered
- StackBlitz may start, pause or resume these practices without treating it as a policy change
- Stopping use of Forge does not by itself withdraw consent for content already collected
Won back
- Opt-out is free and available on all plans, via account settings or email
- EEA, UK and Swiss accounts are excluded from model training and dataset licensing, and accounts of unknown location are treated as in those regions
- Content used only on StackBlitz.com, the SDK or WebContainer API is excluded
- 30-day export period after non-cause termination or suspension
- Datasets are de-identified, and recipients are contractually barred from re-identifying
