data privacy university
DSAR. PII. PHI. TCPA. Express written consent. These terms decide what companies owe you and what you owe your customers — and most explanations of them are written by lawyers for lawyers. These are not.
Free, no signup, no gate. Written to be quoted: every guide opens with a direct answer you can lift, and says plainly where the honest answer is "it depends" or "that rule no longer applies."
The vocabulary, defined plainly.
What is PII?
allPersonally identifiable information is any data that can identify a specific person, alone or combined with other data. What counts is broader than most people expect.
What is PHI?
allProtected health information is health data tied to an identifiable person and held by a covered entity. The second half of that sentence is what most people miss.
What is the difference between consent and notice?
allTelling someone what you will do is notice. Getting their agreement is consent. Many organizations have documented the first and believe they have the second.
What the rules actually require.
What is the TCPA?
businessThe Telephone Consumer Protection Act governs calls and texts to consumers. It carries statutory damages per message, which is why consent evidence matters so much.
What data privacy rights do I have in the US?
consumerThere is no single US privacy law. What you can demand depends on your state — but the practical rights are more consistent than the patchwork suggests.
Who does HIPAA apply to?
businessHIPAA applies to covered entities and their business associates — a narrower group than almost everyone assumes. Being outside it does not mean being unregulated.
What to do about it.
What is a DSAR?
allA data subject access request is a person asking an organization what personal data it holds about them. Here is what it obliges, and how long you have to answer.
What is prior express written consent?
businessThe TCPA's highest consent standard has specific content requirements. Most consent records fail on the disclosure, not the signature.
How do you prove consent was given?
businessMost consent records prove a form was submitted. Very few prove what the person was actually shown. That gap is where disputes are lost.
How do I stop companies from selling my data?
consumerOpt-out rights exist in most states, and there is now a browser signal that exercises them automatically. Most people use neither.
What is data minimization?
businessEvery field you do not collect is one you never have to secure, disclose, delete, or explain. Minimization is the cheapest privacy control there is.
PRYVC builds consent infrastructure, so we have an obvious interest in people understanding consent. We would rather that interest be stated than hidden. These guides are not a sales funnel: they describe the law and the practice as they are, including the parts where the honest answer is that a rule was struck down, or that a term means less than it sounds like.
Nothing here is legal advice. Privacy law is fact-specific and moves quickly. Where a guide states a deadline, a damages figure, or a rule's status, check it against current sources before relying on it.
