Data we do NOT collect
We do not collect or store: values entered in calculators, calculation results, financial data, personal documents (CPF, RG), or banking/credit card information.
4. Your Rights (LGPD Art. 18)
Under Brazil's LGPD, you have the right to: confirm data processing, access your data, correct inaccurate data, request anonymization or deletion, data portability, revoke consent, and oppose processing. Contact our Data Protection Officer at privacidade@sethian.com.br.
5. Security
We use SSL/TLS encryption, client-side processing (your data stays in your browser), IP anonymization, and restricted access controls to protect your information.
