In theory you should be able to publish your own list of stories if you don't break them down explicitly and thus overlap much of the book / method 's value. In that case it would simply be a resource for Heisig learners in your language.

edit: rereading your 1 st post I notice you mentioned you never owned the book. That is a point worth considering. If you want the author / publisher's approval you need to at least recognize the value that they created. Heisig created value with his method.

It doesn't hurt to email Heisig and politely ask and be on good terms with him/his publisher. I can only speak in the context of the website since when I asked Heisig many years ago, I was very clear to him (via email) how I would use the keywords, and that my site didn't index the components as such. A lot of time passed since and maybe they are more, or less open towards derivatives.

I think it was important to them that my site was free too. We had a discussion a long time ago on the forum and I think it's possible to pay them royalties if you made an app. I think that must be the case for the official Remembering the Kanji app.

For a simple list of stories where you don't explicitly break down the components, that should be fine. Maybe explain that to the contact you have. Otherwise I'm sorry not much we can do. You could also take advice from a lawyer if it's really important to you. You don't need to go to court for that, just take an appointment with a lawyer or whatever they are called in your country, that knows a little bit about copyrights, and have them write a latter in response to the publisher stating x or y or z. And it might be that and you may never hear from them again. Or he might tell you it's a gray area and you may not want to spend any more on it.
