The app
Privacy
This app lives at https://app.michaelthornbooks.com. It is a companion to the novels — not a replacement for michaelthornbooks.com. Last updated August 19, 2026.
What this app collects
If you send a letter, it is emailed to [email protected]. We may also keep the name, email, topic, and message so a signed-in reader can see their own copies later.
Sign-in
You may sign in with Google or X. Those companies send us a name and email so we can attach letters to your account. We do not get your password. You can use the app without signing in; anonymous letters are still delivered.
What we do not do
We do not sell your information. We do not run ads in this app. We do not take card numbers. Paperbacks are sold on Amazon; when you buy, you leave this app and deal with Amazon under their privacy policy.
Cookies and accounts
A signed-in session uses a cookie (or a short-lived token in preview) so the app knows it is you. That is the whole of it.
How long we keep it
Letters stay until they are answered or you ask that they be deleted. Sign-in records last as long as your account does.
Children
This app is not directed at children under 13. Do not send a letter on behalf of a child that age.
Ask us
To read, correct, or delete what we have of yours, send a letter. Say so plainly. We will handle it.
