Privacy Policy

1. About this policy

This Privacy Policy describes how OOO “Sistemy Snizheniya Treniya” (“SSTR”, “we”) handles personal data collected through sstr.tech (the “Site”). We process data under Russian Federal Law No. 152-FZ “On Personal Data”.

By using the Site, submitting a form, or contacting us at the listed channels, you confirm that you have read this policy and agree to the processing of personal data described below.

2. Data we collect

When you interact with the Site, we may receive:

• your name (if provided in a form);
• your email address;
• your phone number;
• the message you send through a form;
• technical data: IP address, device type, User-Agent, referrer, visit time — captured automatically by server logs.

We do not request or process special categories of personal data (race, political views, health information, etc.).

3. How we use data

We use the data we receive only to:

• respond to your message;
• provide the engineering consultation or calculation you requested;

We keep data no longer than necessary. Contact details and correspondence are retained for the duration of our exchange and for 3 years afterwards (the general civil statute of limitations under Russian law). Server logs are kept for up to 90 days.

We do not sell your personal data and do not share it for marketing purposes. We disclose data only to:

• technical service providers (hosting, transactional email) — under confidentiality terms, limited to what is needed to provide the service;
• government authorities — when required by a lawful request under Russian legislation.

7. Cookies and analytics

The Site uses functional cookies to remember your language preference and to keep basic web-app state. We do not place marketing or advertising cookies. You can disable cookies in your browser settings; the Site will keep working with minor limitations.
