Who handles your data
Hiperion Accounting Advisory is the controller of the personal data collected on this website.
R. Barão de Ijuí, 131, 1º andar · Liberdade · São Paulo, SP · 01502-010
What we collect
- Data you send through the contact form: name, e-mail, company, subject and message.
- Data you share when you reach us by WhatsApp, phone or e-mail.
- Technical records generated automatically by the server, such as IP address and the date and time of the visit, used for security and abuse prevention.
Why we handle it
- To answer your message and prepare proposals, as a preliminary step of a contract.
- To keep the site secure and prevent automated submissions, on the basis of legitimate interest.
- To comply with the legal and regulatory duties of accounting work.
Who we share it with
We do not sell or trade your data. It may be accessed by the providers that host the website and the firm's e-mail, always limited to the purposes above, and by authorities when the law requires it.
How long we keep it
Contact messages are kept for as long as needed to answer you and to keep a record of the relationship. Client data follows the retention periods required by Brazilian accounting and tax rules. After that, data is deleted or anonymized.
Cookies and local storage
This website uses no advertising cookies and no third party tracking tools.
We only store your theme choice, light or dark, in your browser's local storage. That value stays on your device and is never sent to Hiperion. Clearing the site data in your browser removes it.
Your rights
The law gives you the right, at any time, to:
- Confirm whether we handle your data and access it.
- Correct incomplete, inaccurate or outdated data.
- Request the anonymization, blocking or deletion of unnecessary data.
- Request portability of your data to another provider.
- Know who we share your data with.
- Withdraw consent, where consent is the legal basis.
How to exercise your rights
Contact us through any of the channels on the contact page, stating your request and how to reach you. We reply within 15 days, the period set by law.
Security
We apply technical and administrative measures to protect data against unauthorized access, loss and improper disclosure, with access restricted to the team that needs it. No system is completely immune, so we review these measures regularly.
Changes to this policy
We may update this text to reflect changes on the website or in the law. The date of the last update appears right below the title of this page.
