Who we are

BNYA (GREENBER BNYA AI LTD) builds and runs an AI agent for budget control in construction projects. This page explains what personal information we receive, why, how long we keep it and who it is shared with. It covers the website bnya.ai, the system our customers work in and BNYA's WhatsApp numbers.

Our role

The companies that work with BNYA (our customers) own their information. Each customer has a database of its own, and we process the information in it on the customer's behalf and on its instructions. If you work for a customer, you can turn to your company's administrator about your information — or to us directly.

What we receive

• A request through the website: name, company, role, phone and e-mail (optional) — only to get back to you.
• An account in the system: name, e-mail, role in the project, and phone — to know who you are when you write on WhatsApp.
• WhatsApp messages: when you write to a BNYA WhatsApp number we receive your phone number, what you send (text, photos and files) and when, and we keep the messages the agent sends you.
• Project data: records and documents the customer uploads or connects — invoices, orders, contracts, bills of quantities, schedules — and what they contain, such as names of suppliers and contacts.
• Activity records: who made or approved each change, for control and audit.
• Technical information: errors, performance data and recordings of how the system is used (what was on screen and what was clicked), to find and fix problems.

How we use it

Only to provide the service: to answer messages, run the budget control, send updates and questions to the project's people, manage access and fix problems. We do not sell personal information, use it for advertising, or share it beyond what is described here.

WhatsApp

Messages travel through Meta's WhatsApp. We use information received from WhatsApp only to answer you and to do the work your company uses BNYA for — not for advertising or any other purpose. If more than 24 hours have passed since your last message, you first get a short notice that a new message is waiting, and its content only once you choose to read it. To stop receiving messages, write to us or to your company's administrator.

Who it is shared with

With service providers that process information for us, each only as far as it needs to:

• Supabase — databases and file storage (Frankfurt, Germany).
• Amazon Web Services — each customer's servers (Frankfurt, Germany).
• Anthropic — the AI model (Claude) that reads messages and documents and drafts answers; processing may take place in the United States.
• Meta (WhatsApp) — delivering WhatsApp messages.
• Sentry — error tracking and recordings of system use (servers in the EU).
• Cloudflare — hosting the website and the system.
• Resend — sending e-mail: invitations, password resets and website requests.

Beyond that, we disclose information only when the law requires it.

How long we keep it

These are the defaults; each customer can change them for its own data.

• WhatsApp message content and the files sent in them — 90 days. Then the content is deleted, and the phone number is kept masked (its last four digits only) for statistics, up to 13 months.
• A conversation not used — 90 days.
• Records of the agent's cost and use, without content — 13 months.
• Project records, documents and activity records — while the project is active with the customer, or as the customer decides.
• A website request — as long as needed to handle it.

Your rights

Under Israel's Privacy Protection Law (and the GDPR where it applies) you may ask to see, correct or delete the information about you, and ask us to stop sending you messages. A deletion request by phone number deletes the content of your messages and conversations and removes the phone from your account. Write to info@bnya.ai or to your company's administrator.

Security

Each customer has a database of its own. Access requires signing in and a role-based permission, connections are encrypted, an idle session ends by itself, and every change of permissions is recorded.

Cookies

The website bnya.ai uses no advertising or tracking cookies. The system keeps in your browser only what is needed to keep you signed in.

Changes and contact

When something changes we update this page, with the date at its top. For any question: info@bnya.ai.
