What Atlan's privacy policy and terms of service say about your data

D1.4 downgrade: owner claim qualified by carve-out

Customer owns outputs but "understands that AI Inputs...may generate same or similar AI Outputs" to other customers' outputs, shared/ambiguous reuse.

D5.1 downgrade: vague disclosure

Outputs "tagged as such" is a labeling assertion without concrete disclosure mechanism, half for naming without detail.

D6.1 upgrade: explicit refusal of ADM

"We do not use any automated processes to make decisions about you that produce legal or significant effects" is a direct, named prohibition, full.

All adverse flags: false

No silence on training, deletion, sales, or licensing. No perpetual/sublicensable clauses, no opt-out-only for harmful use, no indefinite retention.

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: shorter retention for AI conversation logs
Only partial: your ownership of generated outputs
Only partial: a retention period for your data
