Khwarizmi Support

Help, answers, and how to reach a human

Contact: contact@zeroais.com — a real person reads it, usually within two working days. Tell us your device, whether you signed in with Apple, Google, or an email code, and what happened.

Common questions

How do I delete my account?

Open Settings in the app and tap Delete account. Your account record, sign-in sessions, subscription record, and usage counters are permanently removed from our server, and the chats, projects, and files stored for that account on your device are erased. It cannot be undone. If a subscription is active, cancel it separately in your app store account — deleting the account does not cancel store billing.

How do I manage or cancel Khwarizmi Plus?

Subscriptions are billed by your app store, not by us.

iPhone/iPad: Settings app → tap your name → Subscriptions → Khwarizmi.
Android: Play Store → profile icon → Payments and subscriptions → Subscriptions → Khwarizmi.

You keep Plus until the end of the period you already paid for. Refunds are handled by the store, not by ZEROAI.

I paid but I'm still on the free plan

Open the upgrade screen and tap Restore purchases. Store confirmations can take a minute to reach us. If it still says Free after a few minutes, email us with the store receipt and we'll fix it.

What are the daily limits?

The free plan includes 30 messages and 5 attachments per rolling 24-hour window. The window opens with your first message and the full allowance returns 24 hours later — the app tells you when. Khwarizmi Plus raises both limits well beyond normal daily use.

I can't sign in

Guest mode works without an account — tap Skip for now and keep going. If a sign-in code never arrives, check spam, then email us. If Sign in with Apple or Google fails repeatedly, note the exact message you see and send it to us.

Is my conversation data private?

Your chats live on your device, not on our servers. Messages are sent to our server only to generate a reply, and are not kept as conversation history. No ads, no third-party analytics, and your conversations are never used to train AI models. Full detail in the Privacy Policy.
