When you choose Option A (ad-supported) in our cookie banner you consent to a defined set of third-party companies receiving limited data about your visit so that we can fund free journalism. This page lists every category of vendor, the data we transfer, the legal bases we rely on, and how to exercise your rights. If you choose Option B (£1 trial, then £4.99/month) no third-party vendor receives any data at all.

§ 1

Who counts as a vendor

A vendor is any third party that processes personal data in connection with advertising, audience measurement or anti-fraud on blitz-voltage.com. We rely on the IAB Europe Transparency & Consent Framework v2.2 and its Global Vendor List (GVL), maintained at vendor-list.consensu.org. At the time of writing the GVL contains 121 registered vendors that have signed the IAB Europe Policies and accepted joint-controller terms with us.

§ 2

§ 3

TCF v2.2 purposes we ask consent for

  • Purpose 1. Store and/or access information on a device.
  • Purpose 2. Use limited data to select advertising.
  • Purpose 3. Create profiles for personalised advertising.
  • Purpose 4. Use profiles to select personalised advertising.
  • Purpose 5. Create profiles to personalise content.
  • Purpose 6. Use profiles to select personalised content.
  • Purpose 7. Measure advertising performance.
  • Purpose 8. Measure content performance.
  • Purpose 9. Understand audiences through statistics or market research.
  • Purpose 10. Develop and improve services.
  • Purpose 11. Use limited data to select content.

We additionally rely on Special Feature 1 (precise geolocation) only where vendors require it for ad delivery; consent is requested separately. We do not use Special Feature 2 (active scanning of device characteristics).

§ 4

Data fields transferred to vendors

When Option A is selected, the following fields may be transmitted in the OpenRTB bid request and associated measurement pixels. No other personal data leaves our infrastructure.

  • IP address (truncated to /24 for IPv4, /56 for IPv6 where the vendor supports it)
  • User-Agent string and Client Hints (browser, OS, device type, viewport)
  • IAB TCF v2.2 consent string and Google Additional Consent (AC) string
  • Pseudonymous advertising identifiers (Google GPID, RampID, ID5, UID 2.0 where consent granted)
  • First-party Blitz Voltage cookie ID (rotates every 13 months)
  • Page URL, referrer URL, page category and content keywords (excluding article body)
  • Coarse geolocation derived from IP (country, region, city — never precise GPS)
  • Timestamp of the impression and viewability metrics (in-view %, time-in-view)
  • Ad slot identifiers, creative IDs, bid prices and win/loss signals
  • Hashed (SHA-256) email address — only when you are logged in AND have granted advertising consent
  • Subscription tier flag (free vs paid) — used solely to suppress ads for paid readers

We never transfer: your real name, postal address, payment card details, password, comment history, the body text of articles you read, or any special-category data within the meaning of Article 9 UK GDPR.

§ 5

Legal bases

All advertising and audience-measurement processing relies on your consent under Article 6(1)(a) UK GDPR and regulation 6 PECR. Anti-fraud and ad-quality controls (e.g. detecting click farms) additionally rely on our legitimate interests under Article 6(1)(f), with a documented balancing test available on request.

§ 6

International transfers

Where a vendor is based outside the UK we rely, in order of preference, on: (a) the UK adequacy regulations for the EEA; (b) the UK Extension to the EU–US Data Privacy Framework for certified US recipients; (c) the ICO's International Data Transfer Agreement or the EU SCCs with the UK Addendum, supplemented by a Transfer Risk Assessment. The applicable mechanism for each vendor is recorded in the JSON list linked above.

§ 7

Retention and deletion

Bid-stream data is retained by vendors for a maximum of 13 months unless a shorter period is stated above. Our own ad-request logs are truncated to aggregate counters after 30 days. You can request deletion of all vendor-side identifiers tied to your account by emailing [email protected]; we forward the request to every vendor within 72 hours under Article 19 UK GDPR.

§ 8

Your rights and how to withdraw consent

  • Reopen the consent banner at any time via — withdrawal is as easy as the original consent.
  • Request access, rectification, erasure, restriction or portability of your data.
  • Object to processing based on legitimate interests.
  • Lodge a complaint with the Information Commissioner's Office (ico.org.uk · 0303 123 1113).
§ 9

Changes to the vendor list

The IAB Global Vendor List is updated weekly. We re-evaluate additions and removals every Monday; if a new vendor introduces a new purpose or data category we will re-prompt for consent before any data is shared. A signed changelog is available at blitz-voltage.com/vendors/changelog.
