Privacy notice
Comprehensive privacy notice under Mexican legislation on personal data held by private parties.
Data controller
Pureza, operator of pureza.mx, is responsible for processing personal data collected through this website. Contact contacto@pureza.mx about this notice.
Data collected
- Identification and contact: name, email address and telephone number.
- Delivery: address and delivery instructions.
- Billing data when a tax invoice is requested.
- Technical browsing data necessary to operate the website.
Primary purposes
Processing orders, coordinating shipments, issuing tax invoices and responding to support requests.
Secondary purposes
Measuring the performance of advertising campaigns that bring visitors to the site. Pseudonymized identifiers are shared with advertising platforms for this purpose. You may object by writing to contacto@pureza.mx without affecting your order.
Cookies and local storage
The site uses the TikTok measurement pixel, which sets platform cookies to attribute visits and orders to advertising campaigns. Cart contents are saved in browser local storage. When payment is initiated, the email address and telephone number entered are shared with the advertising platform as SHA-256 hashes, rather than plain text. Hashing pseudonymizes these identifiers; it does not make them anonymous.
- pz_bump_descargo: records for one year that the cart consumable disclaimer has been displayed.
- pz_bump_no: records for thirty days, using the current cart’s random identifier, that the consumable offer was dismissed.
- pz_verificado: records for thirty days the researcher declaration that grants access to commercial pages.
- pz_attr: stores visit attribution for ninety days, including the ad or link identifier, campaign parameters, landing page and referring website. Its purpose is to measure channels that bring visits and orders, and the cookie is not readable by browser scripts.
Data sharing
Data are shared with delivery and payment-processing providers as needed to fulfill the order. Advertising platforms receive pseudonymized identifiers for the measurement purpose described above.
ARCO rights
To exercise rights of access, rectification, cancellation or objection (ARCO), or withdraw consent to data processing, write to contacto@pureza.mx with your name and a way to contact you. Requests are handled within the time limits established by applicable law.
