Privacy policy
Last updated: November 1, 2026.
Files, text and passwords
The tools process content on your device. Their code does not send files, JSON, tokens or Wi-Fi passwords to the server, and does not save them in cookies or local storage. Results remain on the page or are saved on your device when downloaded.
Your language preference
Choosing a language saves the nandez_lang cookie for up to one year. It only contains es, en or pt-br and remembers your choice when visiting the site root. It contains no tool data and is not used for advertising. You can delete it in your browser. Language-specific URLs always use the language in their address.
Wi-Fi QR codes
The code contains the network password, which anyone with access to the QR can read. Only share it with people who should connect.
Hosting technical data
The hosting server may log IP address, date, requested URL, browser and errors. This differs from content processed by the tools. Retention and configuration depend on the provider and site operator.
External resources and contact
QR and PDF libraries are served from this site. External links have their own policies. Contact emails are processed by the relevant email providers.
Advertising and cookies
AdSense integration is disabled in this version. If enabled, this policy and consent controls must reflect the providers and processing actually used.
