Privacy & Data Rights

Privacy policy

This is the public-facing privacy notice for people whose data Prosigna may hold. It is written to satisfy Article 14 of the UK GDPR (information to be provided where personal data has not been obtained from the data subject).

Who we are

Prosigna is an intelligence platform that surfaces wealth events to regulated financial services professionals. We are the controller of the personal data described in this notice.

Prosigna is operated by Burst Technologies, trading as Prosigna ("Prosigna", "we").

Correspondence address: Prosigna, 800 N King Street, Suite 304-2311, Wilmington, DE 19801, USA. Email: info@prosigna.io.

What data we hold about you

If you appear in Prosigna, we may hold:

- Your name

- Your role and the company or organisation associated with you in public filings

- Public-record information about an event you are connected to (e.g., a director appointment, an SEC filing, a property transaction, a probate grant)

- Limited business-context contact information (work email, work phone, business address) where available from public sources or contact enrichment services

- A LinkedIn URL where one is associated with your name and company in public web search results

We do not hold:

- Government-issued identifiers (national insurance, social security)

- Financial account details

- Health, religion, or other special category data

- Personal (non-work) contact details, where avoidable

Where we got it

We obtain personal data from:

- UK Companies House

- HM Land Registry

- The London Gazette

- The Probate Registry

- US Securities and Exchange Commission (EDGAR)

- Press articles and publicly available web content

- Third-party contact enrichment services that themselves rely on publicly available business information

Why we hold it

We use this data to identify wealth events and surface them as time-limited prospect briefs to wealth managers, private banks, family offices, and other regulated financial services firms.

Our legal basis is legitimate interests under Article 6(1)(f) UK GDPR. The legitimate interest is in providing regulated financial professionals with timely intelligence about wealth events drawn from statutorily public sources. We have conducted a Legitimate Interests Assessment that documents this balance. See our Compliance page for more detail.

We use automated scoring to estimate the likelihood and timing of a wealth event. We do not make solely automated decisions about you that produce legal or similarly significant effects.

Who we share it with

We share your personal data with:

- Subscribing firms (wealth managers, private banks, family offices, broker-dealers, RIAs) — but only after they purchase a specific brief about you. Once they do, they become an independent controller and are required to provide you with their own privacy notice when they first contact you.

We do not share your personal data with advertisers, consumer marketers, data brokers for resale, or political organisations. It is provided only to subscribing regulated financial firms, and only after they purchase a brief; US state privacy law treats that disclosure as a sale, and the notice for US residents below explains how to opt out.

How long we keep it

We keep prospect briefs for a maximum of 12 months from the date of the underlying event. After that, the brief is removed from active inventory.

If you opt out (see below), we add your name and company to a suppression list, remove any existing briefs about you immediately, and retain the suppression record indefinitely so that you are not re-introduced.

Your rights

You have the right to:

- Object: To our processing. We will stop processing your personal data unless we can demonstrate compelling legitimate grounds that override your interests. For most prospect briefs, an objection will result in immediate removal.

- Access: The personal data we hold about you.

- Correct: Inaccurate personal data.

- Erase: Your personal data, subject to certain exceptions (e.g., where we are required to retain audit records).

- Restrict: Processing while we investigate a complaint.

- Portability: Receive your personal data in a portable format in certain circumstances.

To exercise any of these rights, use our opt-out form (no account required) or email info@prosigna.io. We respond within one month.

You also have the right to complain to the Information Commissioner's Office (ICO) at ico.org.uk.

Notice for US residents

For US residents, the personal information we collect includes:

- Identifiers such as your name and business contact details

- Professional and employment information

- Publicly available information from government filings and statutory registers

- Inferences such as the likelihood of a liquidity event

We obtain this information from public filings and statutory registers, and from licensed contact-data providers. We use it to provide wealth-event intelligence to subscribing financial firms. Personal information is provided to subscribing firms for a fee when they select a brief about you.

You have the right to know what personal information we hold, to request deletion or correction, and to opt out of the sale or sharing of your personal information. We will not discriminate against you for exercising any of these rights.

You can opt out through the Do Not Sell or Share My Personal Information link or the /gdpr form, and make any request by emailing info@prosigna.io. We act on opt-out requests within 15 business days and answer requests to know, delete or correct within 45 days.

International transfers

Where we transfer personal data outside the UK or EEA, we rely on UK International Data Transfer Agreements or EU Standard Contractual Clauses.

If you are in the EU or EEA, references to the UK GDPR include the equivalent provisions of the EU GDPR.
