About this notice

OPEN SI Establishment operates osisys.com and Open SI’s development real-estate assistant service. This notice covers both. It explains information used by the features currently available and identifies planned notification functionality separately.

Information we use

When you contact us, we receive the information you choose to include, such as your name, email address and message. The company website currently provides email links. If you submit a message through our contact-message service, we also store a message identifier, submission time and a derived identifier used to limit repeated requests.

If you use the development service, we store account and verification information, your phone number, profile details you provide, your conversations and submitted actions, and your saved consent and notification choices. Office profiles can include a public name, office or individual type and entered licence details.

We use this information to provide account access, maintain the service and your conversation history, apply your choices, respond to requests, and protect against misuse.

Browser storage

The company website remembers your chosen colour theme in your browser. The development service uses cookies and browser storage for sign-in, request protection, unfinished drafts and recovery of pending actions. Clearing browser storage can remove these local preferences or interrupt access; it does not itself delete information already stored by the service.

Who receives information

Our hosting and storage providers process information needed to operate the sites. Email providers process messages sent through the contact links. An SMS verification provider processes the phone verification requests used for registration, code sign-in and self-service phone changes.

Information made available to a particular assistant is governed by that assistant’s access permissions. It is not made available to another assistant merely because you use both. Authorized administrators can inspect accounts and retained conversations for support and administration.

Notifications and planned features

Account notification preferences are available in the service’s settings. These choices are separate from verification codes requested for account access. Registration consent is recorded, and channel preferences can subsequently be changed.

WhatsApp service notifications are planned and are not currently operating. If enabled, Meta/WhatsApp would process recipient numbers, notification content and delivery information. Listing publication and saved-preference memory are also not currently enabled in the development service.

Retention and deletion

The current development service does not automatically delete account or conversation records after a fixed period. Signing out, clearing browser storage or reaching the end of a guest-access session does not delete those server-held records. Messages saved through the company website’s contact-message service also have no automatic deletion schedule in the current implementation.

You can contact us to request access, correction or deletion of your information. Please do not include passwords or verification codes in your request.
