The Expedition Post is the data controller for the information described here — we decide what is collected and why. Accounts are held by parents and guardians, not by children.
Card and billing details are collected and held by our payment provider, not by us. We never see your full card number.
To write each letter, the child's first name, age and interests are sent to an AI text provider that generates the letter and Membership pages. That information is used to produce your content, is not used to identify the child, and we do not permit it to be used to train public models. Destination photographs are retrieved from a stock photography service using only the destination name.
We do not sell personal information and we do not advertise to children.
Account details, explorer profiles and letters are kept for as long as your account is open. Delete an explorer and their profile and letters go with it. Close your account and we delete your data within 30 days, except records we must keep for tax and accounting. Support messages are kept for two years.
You can ask us to give you a copy of your data, correct it, delete it, restrict or object to how we use it, or withdraw consent where we relied on it. Much of this you can do yourself from your Letter Shelf. Write to us through the contact page and we'll respond within one month. If you are in the UK or EEA you also have the right to complain to your local supervisory authority. Where data is processed outside your region, we rely on appropriate safeguards such as standard contractual clauses.
Data is encrypted in transit and at rest, access is restricted, and each account can only read its own records. We use essential cookies and local storage to keep you signed in and to process payments. We do not use advertising or tracking cookies, so there is nothing to opt out of — clearing your browser storage signs you out.
