Estimated Market Value
$0.0000
Data is worth more for users who buy more: ad buyers pay a premium for high commercial intent — the auction study below found that users actively shopping for a product sell for more than their browsing history alone. We index your value against the average online shopper (≈$280/month in the U.S.), so the estimate scales with your spend — double the average spend, double the commercial-intent value.
Why an email address matters. On their own, cookies are anonymous identifiers tied to one browser. Attaching a (hashed) email address links them to a persistent, cross-device identity — the basis of the “identity resolution” that advertisers pay a premium for. Industry measurements put the uplift from authenticated, email-linked audiences at roughly +20% to +40% in yield, with email-based universal IDs reported as high as +116% effective CPM versus cookies alone. Our model applies a representative 2× uplift.
Each cookie is valued as
Base × Persistence × Security, summed across all
cookies, then scaled by your spend and (optionally) an email uplift:
Total = (Σ cookies) × Spend index × Email.
Figures are illustrative estimates of wholesale ad-market value, not an offer of payment. Real prices vary by buyer, geography, and intent.
Cookie Segments
Each cookie is sorted into a segment based on its domain and name patterns. Segment mix influences which tranches your dataset is eligible for.
List Your Dataset
Your account is in good standing when the following are true. Violation of any removes a listing from the market immediately.
Once listed, your dataset can be unlocked by any number of verified buyers — each unlock pays you the full amount, independently. Your data is licensed, not sold. It earns every time it is accessed.
YouDB lists data but does not guarantee a transaction. Purchase decisions are made by buyers if they’re available and interested.
A fresh upload is required before re-listing. Upload new data above, then re-certify all three statements.

Credits & Referrals
Credits are the unit of upload capacity: 1 credit = 1 KB of accepted, de-duplicated data (~8 cookie records). The floor monthly price is always non-zero — but referrals earn real credits and are heavily rewarded.

Unlimited credits
Share your unique referral link. Every new account that signs up through it earns you +25 credits instantly. When they complete their first paid month, you earn +150 more (or one free month at your tier — your choice). They get 50% off their first month. The floor monthly price stays non-zero for everyone — referrals buy capacity, not a free ride.

Why This Matters
There is a simple transaction at the heart of the modern web that nobody disclosed to you. When you visit a website, your browser sends signals — cookies, identifiers, behavioural traces — that tell advertisers who you are and what you want. Those signals are sold, in real time, at auction. The price they fetch funds the content you read, the platforms you use, the creators you follow. Everyone in that chain is compensated.
Except you.
