5. Legal bases (UK GDPR)

Where we act as controller, we rely on:

Where we act as processor for Customer Data, we process it under your instructions and our agreement with you.

c) Ensure correct operation and maintenance of systems and databases
d) Produce aggregated anonymous averages for insights/publications

7. Security

Your data is sent securely across the internet using TLS/SSL encryption in transit. While we take appropriate technical and organisational measures, the internet is not a fully secure environment.

You are responsible for:

• keeping your password safe,
• keeping your devices and software up to date,

The Service may use cookies and similar technologies to operate effectively and understand usage patterns. You can manage cookies through your browser settings and, where applicable, our consent banner.

We send billing information, product information, service updates, and notifications via email. Where appropriate, emails include opt-out instructions for non-essential communications. Service/billing messages may still be sent where necessary to deliver the Service.

10. Data access, export, and deletion

Provided you have met your obligations under the Service Terms of Use, you can download/export your data via the Service.

Retention after cancellation: Customer Data may be permanently deleted 60 days after you stop paying for the Service or earlier at your request.

Backups: Backups may persist for a limited period after deletion/cancellation and are overwritten on a rolling basis. [BACKUP RETENTION TO CONFIRM]

We may retain limited information where required for legal, accounting, security, or dispute-resolution purposes.

11. Your rights

Depending on the context and applicable law, you may have rights to:

• access, rectify, erase, restrict, or port your personal data,
• object to processing,
• withdraw consent (where processing is based on consent).

For Customer Data you control (your end-customer/job data), you are typically the controller and responsible for handling data subject requests; we will assist where required under our agreement.
