LGPD compliance for an AI writing tool
Lei Geral de Proteção de Dados Pessoais (Lei nº 13.709/2018). This page applies it to one kind of product (AI writing tool), so you get the obligations that are actually yours instead of a summary of the whole statute.
Does it apply to you?
Processing carried out in Brazil or aimed at offering goods or services in Brazil.
What an AI writing tool typically processes
- user text sent to a model provider for completion
- drafts and history stored per account
- usage metering for billing
Each of these is processing you have to disclose. Adding an SDK later adds to this list — which is why a policy written once goes stale.
Documents you need
The intersection of what LGPD requires and what an AI writing tool actually does:
- Privacy policy
- Terms of service
Rights you must honour
LGPD gives people in Brazil the right to:
- Access a copy of their data
- Correct inaccurate data
- Have their data deleted
- Receive their data in a portable format
- Object to certain processing
- Withdraw consent at any time
- Ask for human review of an automated decision
