We collect your name, email address and optional phone number to process your PPR request and manage airfield operations, including safety and operational coordination. This data is processed under our legitimate interests in operating Sleap Airfield safely and efficiently. Your email address, phone number and any notes you add are deleted three months after your arrival date. If a landing fee is still unpaid then, they are kept until it is settled, and never more than twelve months. Your name and flight details are kept for our airfield movement and accounting records. Access to this data is restricted to authorised staff and it will not be used for marketing purposes. Data may be shared with relevant authorities where required for safety or legal reasons.
