Your information, explained clearly.

Irina Oliveira is the controller of the personal information collected through this website. You can use the contact details below for any privacy question or request.

The inquiry form may collect:

• your name and email address;
• your phone number, if you choose to provide it;
• the student level, IB Mathematics course and intended exam date;
• the message you write about the student and the support being sought; and
• limited technical information generated when the site is used, such as IP address, request details and security logs.

I use this information only for the following purposes and legal bases:

• to read and reply to your inquiry, assess whether I can help, and arrange an introductory call — steps taken at your request before any tutoring agreement;
• to maintain the security, reliability and abuse prevention of the site — my legitimate interest in operating a safe service; and
• to meet a legal obligation or establish, exercise or defend legal claims, where necessary.

Information is shared only when needed with service providers that support the site: Vercel for hosting and security, Resend for transactional email delivery, and the email provider used to receive and reply to inquiries. These providers process information under their own security and data-protection terms.

I do not sell personal information, use it for advertising, or add you to a marketing list. Information may also be disclosed where the law requires it or to professional advisers when necessary.

Some service providers may process information outside the European Economic Area, including in the United States. Where required, transfers are protected by an adequacy decision, Standard Contractual Clauses or another safeguard recognised by data-protection law. You may ask for more information about the applicable safeguards.

Inquiry details and correspondence are kept for as long as needed to reply, assess the request and, if relevant, begin or manage the tutoring relationship. They may be kept longer when required by law or reasonably necessary for legal claims, after which they are deleted or anonymised.

Technical and email-delivery logs are retained according to the operational schedules of the relevant providers and only for as long as needed for delivery, security and troubleshooting.

Depending on the circumstances, you may ask to access, correct, delete or restrict the use of your information, receive it in a portable format, or object to processing based on legitimate interests. These rights are free to exercise, although identity may need to be verified and some legal exceptions may apply.

You also have the right to lodge a complaint with the Portuguese data-protection authority, the Comissão Nacional de Proteção de Dados (CNPD).

Please share only the educational context needed to explain the request. Do not include health information, identification documents or other sensitive or unnecessary details. When an inquiry concerns a minor, a parent or guardian should provide the information where appropriate.

Reasonable technical and organisational measures are used to protect information. No internet service can guarantee absolute security, so please use the direct email address below if you would prefer not to use the form.

This site does not currently use advertising or analytics cookies. Hosting and security systems may still process essential technical information needed to deliver the pages, prevent abuse and keep the service available.
