Data Protection
No a321, privacy isn't red tape — it's respect. This document explains clearly what data we collect, why we collect it, how we protect it, and what your rights are as a Brazilian user. We've written it in plain language so you can understand everything without needing a lawyer.
A321 operates in compliance with the General Data Protection Law (Lei 13.709/2018). We have a dedicated Data Protection Officer (DPO) and internal processes aligned with the ANPD.
All data transmissions between your device and a321's servers are protected by 256-bit SSL encryption — the same standard used by major Brazilian banks such as Itaú and Bradesco.
A321 does not sell, rent, or trade personal data with third parties for commercial purposes. Full stop. Data sharing occurs only with essential operational partners and under confidentiality agreements.
Access, correct, export, or request deletion of your data at any time directly through your account dashboard or by contacting our DPO. All your rights under the LGPD are available to you.
Only strictly necessary cookies are enabled by default. You can manage the rest — analytics and personalization — directly in a321's privacy settings.
A321 does not collect, process, or store data from users under 18 years of age under any circumstances. Accounts created by minors are closed immediately and their data permanently deleted.
