The cadence
Letters arrive weekly. You'll receive a notification when a new letter is waiting. Replies are optional — you can simply read, or you can write back. There is no feed, no algorithm, no pressure to engage.
Privacy
Your correspondence is private. Letter content is never used for analytics, training, or public display. Only the human creative team behind Mateo can see what you write — and only to write you back.
