Security and privacy
We ask for as little as we can get away with, we tell you why we need it, and we do not pass it on. This page sets out what we hold, what we do with it, and how to see it, change it or have it deleted.
We do not share customer data with other companies. We do not store card details. Access, correction and deletion requests are answered within one calendar week. Cookies are used for analytics only.
What we do with your data
The short version is that it stays here and it gets used for the thing you gave it to us for.
We take care when dealing with customer data. We will never share customer data with unnecessary third party data processors, we will never ask for information we do not need, and we will always explain why we need whatever we do ask for.
No customer information is synced across any CRM or third party accounting software, and your data is not shared with other companies.
The details we collect are used to process your order or to process a finance application. We do not store details we have no reason to retain.
What we hold and why
- Order details, to process and deliver your order
- Finance application details, where you have applied for credit
- Contact form submissions, emailed to sales and kept as a soft copy on the website so nothing is lost if email fails
- Invoicing records, which HMRC requires us to keep for seven years
What we do not do
- Share your data with other companies
- Sync it into a CRM or third party accounting software
- Ask for information we have no use for
- Store your card number, which never reaches us in the first place
Your information will be read, and the email may stay in our archive in case we need someone with your skill set in future. By sending a CV you are showing a legitimate interest in working for GSM Performance. If you would rather we did not keep it, email sales@gsmperformance.co.uk and we will remove it.

How we use cookies
Analytics, so we can see how the site is being used and keep it secure.
We use cookies on this website to track visitor behaviour, which helps us improve the site and its security. These are placed by Google Analytics. You can read Google’s privacy and cookie policy for what they collect.
Every browser lets you see and control the cookies it keeps. The relevant instructions are below.
Payment security
Your card number goes straight to the payment provider and never reaches us.
Everything on this site runs over an encrypted connection, and any information you enter is encrypted before it is transmitted. Your browser will show a padlock next to the address on any page where you enter personal or payment information.
Card payments are handled entirely by the payment provider you choose at checkout. The card number is passed straight to them and is never stored by us once your order has been processed. There is nothing on our side for anyone to take, which is also why we cannot write a card number down over the phone for you.
Your provider verifies the details with your bank or card issuer as the payment goes through, usually in a couple of seconds. Enter the cardholder name, address and card details exactly as your bank holds them or the payment may not authorise.
