Litestore keeps your store's data safe, and you can report a problem to us privately.
You and your customers sign in with a link sent by email. Litestore never stores a password.
Litestore allows 5 sign-in tries and 3 emailed links a minute. After that, people have to wait.
The database itself blocks some mistakes. Here it stops a refund that's bigger than the order.
A stock change is only saved when the old quantity plus the change equals the new one.
Payment records can't be edited or deleted.
A payment must match its order's currency.
Two customers can't share an email and two products can't share a SKU, even if the case differs.
Litestore protects your data. Keeping the server safe is up to you.
Please tell us privately through GitHub rather than opening a public issue.
