Support

One person reads every message. Not a bot, not a queue — so allow a day or two, and please say what actually happened.

Only so we can reply. It is not added to any list.

Prefer your own mail app? support@sidezero.app

What helps us answer on the first reply

Your browser (Chrome, Edge), the SideZero version from Settings, which model you were using, and what you expected to happen instead. A screenshot beats a description.

Never send us an API key. We never need one, and we cannot use one. If you have already pasted a key anywhere you are unsure about, revoke it at your provider and issue a new one.

Answers that do not need an email

What are the limits?
5 messages a day with no account, 20 a day signed in, and 200 a day on the $12 plan. Those are the whole limits — we do not use the word "unlimited".

Do my own API keys cost me anything here?
No. On your own key every feature is free and never metered by us. You pay your provider directly, and SideZero shows you the real price of each reply.

Where are my keys stored?
Only in your browser. They are never sent to us and never leave your device — watch the network traffic yourself.

How do I cancel, or delete my account?
Both from your account page: cancelling takes two clicks and keeps the plan until the period you paid for ends. Deleting removes your data immediately.

Something was charged and you did not mean to buy it?
Email us. We would rather refund a confused purchase than keep it.
