Summary
Stability AI's terms include standard broad rights for the company, including mandatory arbitration with a class-action waiver (though an opt-out and small claims carveout exist), broad termination discretion without notice, and non-refundable expiring service credits. Privacy practices include sharing data with advertising partners and analytics providers, which the company itself notes may constitute a data 'sale' under CCPA, though targeted-advertising opt-outs are offered.
