X (formerly Twitter).
Post-acquisition X rewrote the privacy policy to fold your posts, replies, images, and even your biometric ID-verification data into Grok's training pipeline §7.5. DMs aren't end-to-end encrypted for most users §9.4, the AI opt-out is a toggle most users will never find §13, and 'public means public, forever' is now policy §11.1. The TOS can change at any time, and continued use is consent §2.1.
TL;DR — 8 answers.
The eight things you actually want to know, at a glance.
The questions, answered.
No legalese. Every answer the way your most cynical friend would put it.
Do they sell your data?
The full-firehose enterprise API is exactly that: every public post, sold to anyone with a checkbook.
Are they tracking you on other sites?
The X Pixel and embedded post widgets log impressions on millions of third-party pages, signed-in or not.
Can your data train their AI?
Default. Yes. Public posts, replies, images, and (per a 2025 policy revision) DMs in some regions all feed Grok. Opt-out exists in a toggle most users have never seen.
Who can see what you do?
Public posts: everyone, including data licensees and Grok. DMs: X employees and law enforcement on process. Premium+ ID: X plus their verification vendor.
Can you delete everything?
Deleting a post hides it. Copies live in archives, in Grok's training set, and in third-party licensees who've already pulled the firehose.
Do they honor your opt-out?
GPC: ignored. The 'Don't allow my posts to be used for Grok training' toggle was added under regulatory pressure, hidden under Settings > Privacy & Safety > Data sharing.
Special handling for minors?
Account requires 13+. Beyond that, minors get the same algorithmic feed as adults. No specific carve-out for AI training.
Been fined for this before?
USD 150M (FTC, 2022 - phone numbers used for ads). EUR 450K (Irish DPC, 2020 - breach). EU DSA investigation ongoing.
At a glance, honestly.
Eight signals, color-coded. Like a model card for a machine — except the machine is reading your data.
The Privacy Label, honestly.
An Apple-style label for what's collected and a Cranor-style back-of-pack for what they do with it. Every cell links to the exact line in their policy.
The receipts, translated.
Five of the worst clauses, lifted verbatim. Strikethroughs are theirs. Marginalia is ours.
Dark patterns spotted.
Tricks the policy and surrounding UX use to make you "consent" without really consenting.
Your rights, by where you live.
Same company, wildly different rights depending on your jurisdiction. Direct links to the specific opt-out / delete / access flows.
- ✓ Right of access
- ✓ Right to erasure
- ✓ Right to data portability
- ✓ Right to object to processing
- ✓ Right against solely-automated decisions
