Gamma

Trains on user data, no opt-out

The research and development clause says Gamma may use personal information to train its artificial intelligence models, and the policy discloses no opt-out for that training, which raises the train-by-default dealbreaker on an explicit reservation.

Full data-subject rights for Europe

The Notice to European Users grants access, correction, deletion, a machine-readable transfer, restriction, objection, and consent withdrawal, all exercisable by email to privacy@gamma.app.

No concrete retention period

Retention is described only as keeping data to fulfil the purposes for which it was collected, with no fixed number named, so the disclosure stays vague rather than time-bound.

Named transfer safeguard, generic security

International transfers rely on adequacy decisions and standard-form contracts approved by relevant authorities, while security is described only as technical, organizational and physical safeguards with no controls such as TLS or encryption named and no breach-notice commitment.
