Email support@byteshards.com
One person reads every message. Include your device, OS version, and the app version shown next to Profile → Settings → About and we can usually fix it in one reply.
Write to support@byteshards.com for anything: a bug, a wrong answer on a card, a purchase that didn't unlock, a data request, or a feature you want.
To report a factual error on a card, tap Report an issue in the row under the answer while you're studying it — pick a category, add a note, and a human reviews it. To report a shared answer or anything objectionable another learner wrote, email support@byteshards.com with the subject "Report content" and the card name — we aim to review and take down reported content within 24 hours.
Cancelling happens in your store account, not in the ByteShards app. Apple and Google own the billing relationship, so they are the only place a subscription can be changed or stopped. Deleting the app does not cancel a subscription, and neither does deleting your ByteShards account.
Purchases are made through the app store you downloaded from, so refunds are requested from that store and decided by them under their own policies. We never see your payment details and cannot issue a refund ourselves.
If the app is broken for you, please email support@byteshards.com as well — a fix is usually faster than a refund, and if the store asks us to confirm the problem we will.
An account is optional in ByteShards — if you never signed in, there is nothing on our side to delete and uninstalling the app removes your data. If you did sign in, you can delete the account and all synced data at any time.
Profile → Settings → Delete account. This permanently removes your account, synced progress, league history, and friends links. It is immediate and cannot be undone.
Email support@byteshards.com with the subject "Delete my account", from the address you signed in with. We verify and delete within 30 days, and confirm when it's done.
Full detail on what is kept and for how long is in the Privacy Policy.
