attempts buyer buyers download e-book ebook expires feature haven help hours indefinitely issue link number page pdf remain secure security share solutions stamping static thank-you unique valid

I haven't been able to find anything about how to add the stamping feature to my e-book.

Without the stamping feature, how is my e-book secure?

Thank you!

Also, we issue each buyer a unique download link that expires after the number of attempts and hours you specify, so there's no static download link buyers could share that would ever remain valid indefinitely.
