Scope and territorial reach
The General Data Protection Regulation harmonized EU privacy law and replaced Directive 95/46/EC. Direct effect — no national transposition required, though most member states layered additional national acts on top (TDDDG in Germany, Loi Informatique et Libertés in France, DPA 2018 in UK).
Applies extraterritorially under Art 3(2) — any controller offering goods/services to or monitoring behaviour of EU/EEA data subjects, regardless of where the controller is established.
Where it applies — 20 jurisdictions

Seven principles (Article 5)
The constitutional backbone — every processing activity must satisfy all seven simultaneously.
-
01
Lawfulness, fairness, transparency Art 5(1)(a)
Process data on a clear legal basis, fairly, and tell users what you do.
-
02
Purpose limitation Art 5(1)(b)
Collect data for specified, explicit purposes — don't repurpose later.
-
03
Data minimisation Art 5(1)(c)
Only collect what's adequate, relevant, and necessary for the purpose.
-
04
Accuracy Art 5(1)(d)
Keep data accurate and up to date; correct or erase inaccurate data without delay.
-
05
Storage limitation Art 5(1)(e)
Keep data only as long as necessary; define and document retention periods.
-
06
Integrity & confidentiality Art 5(1)(f)
Protect data against unauthorized access, loss, or destruction (security).
-
07
Accountability Art 5(2)
Demonstrate compliance — document everything (ROPA, DPIA, policies).
Six lawful bases (Article 6)
You must identify and document one before processing — and consent isn't always the right one.
Consent
User explicitly opts in (free, specific, informed, unambiguous).
Contract
Necessary to perform a contract with the user.
Legal obligation
Required by law (tax records, AML, GDPR itself).
Vital interests
Necessary to protect someone's life.
Public task
Performing a task in the public interest / official authority.
Legitimate interest
Your interest doesn't override user rights — needs an LIA.
Eight data-subject rights (Articles 12–22)
What individuals can demand from you, with the response window and scope.
| Right | Article | Response | Scope |
|---|---|---|---|
| Right to be informed | Art 13–14 | At collection | At collection — privacy notice must be transparent. |
| Right of access | Art 15 | 30 days | User can request copy of all their data. |
| Right to rectification | Art 16 | 30 days | Correct inaccurate or incomplete data. |
| Right to erasure | Art 17 | 30 days | "Right to be forgotten" — deletion under specific conditions. |
| Right to restrict processing | Art 18 | 30 days | Pause processing while disputes are resolved. |
| Right to data portability | Art 20 | 30 days | Receive data in machine-readable format, transfer to another controller. |
| Right to object | Art 21 | 30 days | Object to processing (esp. direct marketing — absolute right). |
| Rights re: automated decisions | Art 22 | 30 days | Not subject to solely-automated decisions with legal effect. |
Fines & enforcement
Maximum administrative penalty: €20.0M or 4% of global annual turnover (Art 83(5)). Tiered structure: Art 83(4) = 2% / €10M for procedural failures.

National addons
GDPR is a Regulation — directly applicable, no transposition required. But Member States layer additional rules on top via national acts.
| Country | National act | Stricter than GDPR baseline? | Note |
|---|---|---|---|
| 🇩🇪 Germany DE | TDDDG (ex-TTDSG) + BDSG | Stricter | TTDSG renamed TDDDG on 14 May 2024 to align with EU Digital Services Act; §25 cookie-consent rule unchanged and stricter than ePrivacy. |
| 🇫🇷 France FR | Loi Informatique et Libertés | Stricter | CNIL issued formal notices (mises en demeure) on GA4 from Feb 2022 — no fine, but drove migration. Post-DPF (2023) practical posture relaxed for DPF-certified Google entities. |
| 🇮🇹 Italy IT | Codice Privacy | Stricter | Garante prov. 9782890 (23 Jun 2022, Caffeina Media) ruled pre-DPF GA4 transfers unlawful. Post-DPF (Jul 2023) the transfer dimension shifted; ePrivacy/consent issues remain. |
