Verified Data. Guaranteed Compliance.
Why Compliance Matters
Data protection isn’t optional — it’s what defines the credibility of your business. At TheSellersIndex, compliance is built into every layer of our verification process. We operate under UK ICO registration, Cyber Essentials certification, and PCI-level payment security through
Stripe.
That means the data you buy is:
-
Lawful:
processed under legitimate interest (GDPR Article 6 (1)(f)). -
Secure:
encrypted end-to-end from verification to download -
Accountable:
timestamped, auditable, and retraceable for 90 days. - We don’t trade in lists. We provide verified business intelligence — structured, lawful, and ready for responsible use.

GDPR in Plain English
The legal foundation for how we process data
We process business information under the GDPR principle of legitimate interest.
In simple terms: we only handle data where there’s a clear commercial reason to do so — B2B communication
with verified companies.
- We never process personal data unrelated to business activity.
- We mask all emails until lawful contact verification exists.
- We remove dormant records every 30 days.
- We provide audit evidence on request under Article 30 (Records of Processing Activities).
- If you’re an agency, marketplace consultant, or investor, this means you can use our data confidently without breaching data-protection law.
Data Security & Payment Protection
- TLS 1.3 encryption across all endpoints.
- Supabase-hosted storage with signed 72-hour download links.
- Stripe Payment Element — PCI L1 certified, no card data stored.
- Multi-factor access control — for internal verification systems.
- Automated deletion — for internal verification systems.
- Result: — zero exposure, zero retention risk, zero compliance surprises.
Our Compliance Promise

This means if you’re ever asked “Where did this data come from?”, you’ll have the answer. Compliance isn’t an afterthought; it’s our commercial advantage.
