This site has no advertising trackers, no analytics scripts, and no cookies set by us. The landed cost calculator runs entirely in your browser — the numbers you type are not transmitted anywhere. We collect only what you send us by email or what is needed to invoice you, we do not sell it, and you can ask us to delete it.
| Data | When | Why |
|---|---|---|
| Name, email address, company name | When you email us or book a call | To reply and to know who we are dealing with |
| Supplier details you share (company name, registration number, quotations, product specifications, photographs) | When you order a check | To perform the check you asked for |
| Invoicing data (billing name, address, tax number if you provide one) | When an invoice is issued | Legal and accounting records |
| Payment data | At checkout | Processed by our payment provider. We do not receive or store card numbers. |
| Server logs (IP address, requested URL, timestamp, user agent) | On every request | Security and abuse prevention, held briefly by our hosting provider |
We do not knowingly collect data from anyone under 18. We do not collect special-category data, and we ask that you do not send it.
Only what is necessary, and only to these categories:
Suppliers you ask us to check will learn that an enquiry was made, because we contact them. They are not told who the client is beyond what is necessary to conduct the check, unless you instruct us otherwise.
Work is performed in China and your data is processed there and in the country where our service providers operate. If you are in the European Economic Area, the United Kingdom, or a jurisdiction with data-transfer restrictions, this means your data leaves your region. Where required we rely on an appropriate transfer mechanism, and we limit what is transferred to what the engagement needs.
You can ask to see the personal data we hold about you, correct it, or have it deleted. You can object to processing or ask for it to be restricted. Write to hello@sourcingproof.com and we will respond within 30 days. We may need to verify your identity first.
If you are in the EEA or UK you also have the right to complain to your local data protection authority. If you are a California resident, you have the right to know what we collect and to request deletion; we do not sell personal information as defined by the CCPA.
Data is held in access-controlled accounts, transmitted over HTTPS, and shared only as described above. No system is perfectly secure. If a breach affects your data, we will notify you and any relevant authority as required by applicable law.
If this policy changes materially, the date at the top changes and, for anyone with an active engagement, we will say so by email.
