We will only send you marketing emails if you have asked us to (for example by ticking the marketing box at checkout). You can withdraw your consent and unsubscribe at any time using the link in any marketing email, or by emailing us at [email protected]. Withdrawing consent will not affect any trade-in or service communications we need to send you about your order.

We do not sell your personal data. We share it only where necessary with:
- Loss/theft verification services (e.g. CheckMEND) to check devices.
- Payment providers and banks, to pay you for your device.
- Delivery and postal services where relevant to your order.
- Our website, hosting, email and analytics providers (including Google) who process data on our behalf.
- Review platforms (e.g. Trustpilot), only where you choose to leave a review.
- Law enforcement or other authorities where we are legally required to do so.
Some of these providers may process data outside the UK; where they do, we take steps to ensure your data is protected by appropriate safeguards.

How long we keep your information
We keep your personal data only for as long as necessary for the purposes above.
