You can delete your account and everything attached to it at any time.
In the app or on the site: open your account, choose Delete account, and confirm. This is immediate and cannot be undone.
By email: write to vj@sagapic.com from the address on the account, with the subject Delete my account. We action it within 30 days and reply when it is done.
If you signed in with Facebook, Google or Apple: removing Sagapic from that provider stops future sign-in but does not by itself delete what we hold. Use either method above so the data is actually erased.
What deletion removes: your email address and password hash, your reading position, shelf and downloads, your preferences, your subscription and purchase records, your credit ledger, and the product events recorded against your account.
What we keep, and why: payment records we are required to retain for tax and accounting, held apart from your account and not usable to identify you as a reader.
