GDPR & Privacy-Notice Checklist for Spain, Mexico and LatAm Sites

What an SMB site actually needs: Spain GDPR/LSSI, Mexico’s aviso de privacidad, cookies, WhatsApp and forms. Not legal advice — the list a €500 pack skips.

Does an SMB need “GDPR compliance” or a copied notice?

It needs to tell the truth about the data it takes. EU Spain is GDPR + LOPDGDD + LSSI. Mexico is an aviso de privacidad. Argentina 25.326. Colombia 1581. A European GDPR paste on a Mexican site that uses WhatsApp is theatre.

Forms and WhatsApp are personal data

A form to a personal Gmail mixes company and private life. Marketing consent is not the same checkbox as “send the request”.

A cookie banner that does not block is decoration

Spain’s AEPD has been clear: non-essential analytics wait for yes. If you do not measure, do not hang ten tags “just in case”.

For an SMB the risk is often a form nobody submits because the notice looks fake — or a Meta ad that cannot find a policy.
