Frequently Asked Questions

Yes, completely — these letters are deeply personal and I respect your privacy 100%. Your collections live in your own private account, so only you can see and manage them when you're signed in.

Each collection also has a unique, unguessable link. Your letters aren't publicly listed or searchable — the only way someone can view them is if you share the link directly. Just remember anyone with the link can open it, so share it only with people you trust.
