TaxNoticeWiz is designed to operate without your personal tax identifiers. Text you submit to the response-letter generator is processed transiently via first-party AI providers under zero-data-retention terms — never stored on our servers, never used for training. Inputs containing obvious identifiers (SSN patterns) are rejected. We collect: the email you provide to unlock the generator, and standard server logs. Do not submit Social Security numbers, taxpayer identification numbers, or financial account numbers — the tools are designed for placeholder data only. Contact: support@taxnoticewiz.com. Operated by RENDUN LIMITED.
