From the very first envelope, the story is written around your child. We weave in their name (or nickname), favourite themes, and milestones (birthdays, first day at school, new sibling) so the plot feels naturally theirs. You can add siblings or friends as sidekicks, choose a world (or rotate across worlds), and we tune length, vocabulary and prompts to their reading stage. Prefer cozy, gentle adventures? Tell us and we'll keep the tone soft and reassuring.
Between chapters you can update details anytime - new interests, different difficulty, a theme switch, even cosmetic touches like wax-seal colour or a keepsake upgrade. Changes made before our next mailing cut-off flow straight into the very next letter; later updates roll to the following one.
Your child also shapes the plot: simple choices via your account determine what happens next, and the next letter reflects their decision - confidence-boosting agency without screens.
We only collect the minimum information needed to personalise the story, never sell data, and you can view or delete details at any time. In short: it's their world, continuously tailored as they grow - while you stay in control with pause/skip options whenever life gets busy.
