These terms are an agreement between you and The Expedition Post ("we", "us"), the provider of this service. By creating an account, requesting a letter, or subscribing, you agree to them. If you are signing up on behalf of a household, you confirm you are an adult with authority to do so.
The Expedition Post generates monthly illustrated letters written in the voice of Rex Wilder, a fictional world traveler, tailored to the age and interests of the child you add to your account. Pro members also receive The Membership and destination photo albums built from each letter. Letters are works of creative non-fiction: destinations, recipes and cultural details are drawn from real places, but Rex is a character and each letter is generated for your family, not reported by a person on the ground.
Keep your login details confidential; you are responsible for activity under your account. Provide accurate information and keep it current. We ask only for a child's first name, age and interests — please do not enter a child's surname, address, school, or any other identifying detail.
You agree not to:
Printing and copying letters and Membership pages for your own family, co-op group or classroom of the children on your account is expressly allowed and encouraged.
We retain ownership of the service, the Rex Wilder character, the illustrations, the design, and the software. You receive a limited, non-exclusive, non-transferable right to use the letters and Membership pages generated for your account for personal and family educational purposes.
Letters and Membership pages are produced with the help of AI and may contain inaccuracies. Please review material before teaching it, and treat recipes, travel details and cultural notes as a starting point rather than verified fact. We do not guarantee that the service will be uninterrupted or error-free, and to the fullest extent permitted by law we disclaim implied warranties of merchantability and fitness for a particular purpose.
Orders are sold by The Expedition Post and processed securely by Stripe, our payment processor. We handle all billing questions, cancellations and returns directly — write to us through our contact page. Our money-back terms are in the 30-Day Guarantee section below. Pro memberships renew automatically until cancelled; cancelling stops the next renewal and you keep Pro access until the end of the period you have already paid for.
We may suspend or terminate access for material breach of these terms, non-payment, suspected fraud or security risk, or repeated misuse. You may close your account at any time; on closure we delete your children's profiles and stored letters, so export or print anything you want to keep first.
To the extent permitted by law, our aggregate liability is limited to the fees you paid in the twelve months before the claim, and we exclude indirect or consequential losses. We do not exclude liability for fraud, death or personal injury caused by negligence. You agree to indemnify us against claims arising from your unlawful use of the service or breach of these terms.
We may update these terms; continued use after an update means you accept the revised version. You may not assign this agreement without our consent; we may assign it as part of a merger or acquisition. Neither party is liable for delays caused by events beyond reasonable control. Questions go to our contact page.
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.
The Expedition Post offers a 30-day money-back guarantee. If a Pro membership isn't right for your family, request a full refund within 30 days of your order date and we'll return what you paid.
Refunds are issued by The Expedition Post through Stripe, back to the card you paid with. Write to us through our contact page and we'll arrange it for you.
You can cancel a Pro membership at any time from Manage billing on your Letter Shelf. Cancelling stops future renewals; you keep Pro access, including The Membership and photo albums, until the end of the period you've already paid for. If a renewal charges you unexpectedly, get in touch and we'll sort it out.
Letters you've already received are free forever and are not affected by a refund or cancellation — only the Pro extras stop.
