Privacy Policy

Last updated: September 28, 2026

1General

TWINA HOME TECH LTD. (טוינה בית הטכנולוגיה בע"מ) (hereinafter: "the Company" or "we") operates the "Haminhelet" system — a service for managing urban-renewal (Pinui-Binui) processes for developers and project stakeholders. This policy explains what personal information we collect, how we use it, and with whom we share it. Use of the service and its associated WhatsApp channel constitutes consent to this policy.

2Information We Collect

  • Apartment owners and authorized representatives: Full name, phone number, ID number, apartment ownership details (address, ownership percentage, signing and measurement status), and messages sent through the WhatsApp channel.
  • Developer representatives and project stakeholders (management system users): Email address for authentication.
  • Technical information: Session login cookie essential for operation, and usage logs for security and maintenance purposes.

3How We Collect Information

  • From the developer or other project stakeholder (such as a lawyer), who enters project, building, and apartment owner data.
  • From your direct communication with the bot on the WhatsApp channel (for example, requesting a meeting).

4Use of WhatsApp and Meta Services

The messaging channel operates via WhatsApp Cloud API provided by Meta Platforms, Inc. Relevant messages and contact details are also processed and transmitted through Meta's servers, subject to WhatsApp/Meta's privacy policy and terms of service. We do not control Meta's processing of information. We recommend reviewing WhatsApp's privacy policy at https://www.whatsapp.com/legal/privacy-policy.

5Consent to Receive WhatsApp Messages

  • Apartment owners are added to the system by project stakeholders (developer or lawyer representing the project), based on their rights in a property participating in an urban-renewal project.
  • Joining the WhatsApp messaging service is done with the explicit consent of the apartment owner (Opt-in), following an initial outreach that provides the project details and the contacting stakeholder.
  • Messages sent are operational only and relate to the project in which the apartment owner participates: scheduling measurement and signing appointments, project status updates, responses to owner-initiated inquiries, and administrative information directly related to the project.
  • We do not send marketing messages, advertisements, or messages unrelated to the project in which the apartment owner participates.
  • Unsubscribing from messages is available at any time through one of two methods: sending the message STOP to the project's WhatsApp channel, or contacting us by email at support@haminhelet.co.il.

6Purposes of Information Use

  • Coordinating and managing measurement and signing appointments within urban-renewal projects.
  • Contacting apartment owners and responding to inquiries.
  • Operation, security, and improvement of the service.

We do not use information for marketing purposes and do not sell personal information.

7Legal Basis

Information processing is carried out in accordance with the Israeli Protection of Privacy Law, 5741-1981, and its regulations.

8Information Sharing with Third Parties

We may share information with:

  • Meta Platforms — for operating the WhatsApp channel.
  • Infrastructure and cloud storage providers, who process information on our behalf subject to confidentiality and security obligations.
  • SMS providers — for delivering one-time login codes by SMS (an Israeli SMS gateway for Israeli numbers; Twilio for international numbers).
  • Artificial-intelligence service providers (OpenAI) — as described in section 9.
  • The developer or project stakeholders for the relevant project.
  • Authorized authorities, as required by law.

9Processing by Artificial-Intelligence Services

A business that registers on the platform confirms, at registration, that project data may be sent to external artificial-intelligence services (currently OpenAI) to improve the user experience. The consent is the business's, over the data it uploads; toward apartment owners, the basis for this processing is this privacy policy.

It is used mainly to understand unstructured information, such as a file in an unfamiliar layout, a name that was not recognised, or a message in the bot. ID and phone numbers are hidden before sending. The service does not train models on the data, and processing follows the data processing agreement and this privacy policy.

10Data Retention

We retain personal information in accordance with the requirements of Israeli law applicable to urban-renewal projects and business documentation. Information that is not legally required to be retained will be deleted or anonymized upon termination of the service.

When you request a code on the public inquiry form, we keep your IP address to prevent abuse, and delete it after 30 days.

11Information Security

We take reasonable measures to protect information, including traffic encryption, access controls, and separation between data of different clients. However, we cannot guarantee absolute security.

12Your Rights

In accordance with the law, you may contact us to review, correct, or delete information about you, subject to retention obligations applicable to us by law. Privacy inquiries can be sent to support@haminhelet.co.il.

13Cookies

The management system uses an essential login cookie only, required for maintaining your authentication. We do not use advertising or tracking cookies.

14Changes to the Policy

We may update this policy from time to time. An updated version will be published on this page along with the update date.
