Privacy
Shenzhen Crafi Technology Co., Ltd. (“CraFi”, “we”) operates https://crafi.tech and BusinessOS. This policy explains what we collect and how we use it. It was last updated on 7 November 2026.
What BusinessOS does
After you sign in, you describe the customer you want. BusinessOS reads public web pages, reviews companies, and prepares an email. When you choose Send, that email leaves from your own mailbox.
Information you give us
Your company website, which you enter before signing in. We read that public page to show a company name.
Messages you type in BusinessOS, the customer description, and the emails you ask us to draft or send.
Appointment requests: name, phone or WeChat, email, company, and question.
Email sign-in
When you continue with email, we send a 6-digit code to that address. We use the code only to sign you in. A correct code opens BusinessOS. We keep the code for up to 10 minutes, then delete it.
We store the account email, company website, and company name. The sign-in lasts 14 days in a cookie in your browser.
Your mailbox
Connect Email Address asks for an authorization code, sometimes called an app password, for the email address you used to sign in. We use it only to send a message you have already reviewed, from that address, when you choose Send.
We do not read your inbox, contacts, or other mailbox contents. We store the code in encrypted form. We do not use mailbox data for advertising.
How we use this information
We use your account, website, and messages to run your BusinessOS workspace: to keep your conversation, search public pages, score a company, and prepare a draft. We use appointment details only to reply to that request.
Each account can generate 10 emails for free. After that, generating an email requires a $10 monthly PayPal subscription. Sending an email that was already generated does not use this allowance. We store the PayPal subscription id, its status, and how many emails the account has generated. We do not store a card number.
Who else processes data
Resend, to deliver the sign-in code to the email address you enter. Resend receives that address and the code.
Your mail provider, when you connect your mailbox, receives the message you chose to send.
Cloudflare, which hosts the site and stores the records described above.
An AI service. We send the conversation, the customer description, text from public pages, and the email draft so the AI can write the reply, the score, and the draft. We do not send your mailbox authorization code or the contents of your mailbox.
Hunter, when a qualified company’s public pages do not show an email address. We send that company’s domain so Hunter can look for a public address. We do not send your account email.
PayPal, when you subscribe. PayPal receives the subscription and processes the $10 monthly payment. We do not send your mailbox authorization code or the contents of your messages to PayPal.
Cookies
We use a sign-in cookie for 14 days, and a short-lived cookie while you enter the email code. The private records page uses a separate administrator cookie. We do not use advertising cookies.
How long we keep it
We keep your account, conversations, company reviews, drafts, sent-mail records, mailbox authorization code, and PayPal subscription record until you ask us to delete them, or until we no longer need them to operate the service. Sign-in codes are deleted within 10 minutes.
Signing out removes the sign-in cookie from that browser. The saved records stay. Appointment requests are kept so we can respond.
Your choices
You can stop using BusinessOS and email us to ask for a copy or deletion of your records.
Send stays unavailable until you connect your own email address.
You can cancel the $10 monthly subscription in BusinessOS. Generating email remains available until the month you already paid for ends. The 10 free generated emails are not billed.
Children
BusinessOS is for companies. We do not intend it for anyone under 16.
Changes
If we change this policy, we will post the new version on this page and change the date above.
