This page says what sellmydata collects, why, and who sees it. It is written to be read, not skimmed past.
What we collect
When you list data: your work email, company name, industry, headcount range, which systems the data comes from, a rough volume, a date range, anything you type in the notes, and the time you ticked the rights confirmation.
When you request access as a lab: your email, your organisation, and your message.
When you sign in: an account with your email, managed by Clerk. We do not store passwords.
Listing is free and needs no upload. The data you list stays with you until you have signed a license with a specific lab.
The data you sell
When a deal is signed, you send the data to us. We remove personal information, such as names, email addresses, phone numbers and similar identifiers, and then deliver it to the lab. We do this to a commercially reasonable standard. No method catches everything, and you will not be able to check the result yourself, so we are telling you plainly: removing personal information is our responsibility, it lowers the risk, and it does not remove it entirely.
We hold the data only to remove personal information and deliver it. We do not sell it to anyone else or use it for anything else.
Why
To show your listing to labs, to contact you when a lab is interested, to show you the status of your listings, and to introduce you to a buyer if you say yes. Nothing else.
Who sees it
Labs see the anonymous parts of a listing: industry, headcount range, systems, volume, dates, and notes. They never see your company name or email unless you agree to an introduction.
The operator of sellmydata sees everything above in order to make introductions.
Services that process it on our behalf: Vercel (hosting and privacy-friendly analytics that set no cookies), Neon (database), Clerk (sign-in), and Resend (email to the operator). We do not sell your contact details to anyone.
Cookies
Two, both needed for the site to work: a sign-in session cookie set by Clerk, and a cookie that remembers a lab has entered the catalog password. No advertising or tracking cookies.
How long
Until you ask us to remove your listing or account. Email us and it is gone within seven days.
Your rights
You can ask for a copy of what we hold about you, ask us to correct it, or ask us to delete it. Email info@sell-my-data.com.
Changes
If this page changes in a way that matters, we email everyone with a listing.
