Fiscalapi respects your privacy and your right to informational self-determination, and ensures that this privacy notice is observed at all times by Fiscalapi or by the third parties with which it has a legal relationship.
The personal data collected depends on the type of legal relationship. By way of example and without limitation:
With respect to the data of the licensees' customers, Fiscalapi acts as data processor on behalf of the licensee, who is the controller with respect to its customers and must have their authorization and its own privacy notice. Fiscalapi processes this data solely to provide the service contracted by the licensee.

You are entitled at all times to exercise your ARCO rights (Access, Rectification, Cancellation, and Opposition: the rights Mexico's personal data protection law gives you over your personal data) under the terms set out in this privacy notice.
ARCO rights allow individuals to exercise control over their personal data:
To exercise any of the ARCO rights, you must send a request by email to legal@fiscalapi.com containing the following:
For the right of rectification, the data subject must also indicate the changes to be made and provide the documentation that supports the request.
We will inform the data subject by email of the decision adopted within a maximum of twenty days from the date the request was received, so that, if it is granted, it takes effect within the fifteen days following the date the response is communicated. These periods may be extended only once, for an equal period, when the circumstances of the case justify it. For the right of access, the data will be delivered once the identity of the data subject or of their legal representative has been proven.
If the request does not meet all the requirements, Fiscalapi may, within the first 5 business days, issue a request for information, which must be answered within the following 10 business days; otherwise, the request will be deemed not submitted.
Fiscalapi may deny access, rectification, cancellation, or opposition in the cases set out in Article 33 of the Law, including: when the data subject or the representative is not duly accredited; when the data is not in the controller's possession; when the rights of a third party would be harmed; when there is a legal impediment or a resolution of a competent authority; and when the rectification, cancellation, or opposition has already been carried out.
The denial may be partial when part of the request does not fall under the grounds above, in which case the corresponding access, rectification, cancellation, or opposition will be carried out. In all cases, we will inform you of the reason for our decision within the established periods and through the same means by which you submitted your request, together with the relevant evidence, where applicable.
Exercising ARCO rights is free of charge; charges may be made only to recover reproduction, copying, or shipping costs.
