Personal data policy
Updated 22 October 2026
How visitor and customer data is processed at https://e-metrix.ru under Russian Federal Law No. 152-FZ.
Contents
Operator and enquiries
The operator is sole proprietor Черемисин Дмитрий Сергеевич (Dmitry Sergeevich Cheremisin). Correspondence and claims: г. Иркутск, ул. Курортная, д. 3, оф. 6. Email: .
Enquiries are handled on working days, Monday–Friday, 10:00–18:00 Irkutsk time (UTC+8). Statutory deadlines apply to personal data requests.
Visiting the website
There are no enquiry forms, accounts, online payments or newsletters. Fonts, icons and illustrations are hosted on this website. Contact controls open your selected email application or messenger.
The server processes IP addresses and technical request information (time, requested URL and browser parameters) to deliver and protect the site. Contact requests use temporary IP-based rate limiting, not advertising. Necessary operation and security processing relies on Article 6(1)(7) of Law No. 152-FZ, subject to visitors’ rights.
Messages, contracts and payment
When you contact us, we use the name, contact details, messages and project materials you provide to reply and discuss your project. Orders may also require customer or representative details, specifications, invoices, receipts and completion records. Please do not send information unnecessary for the task.
Pre-contractual and contractual processing at the customer’s initiative relies on Article 6(1)(5); legally required payment and tax processing relies on Article 6(1)(2). A separate lawful basis is required for another purpose.
Messages, contracts, invoices and completion records are kept in the working Mail.ru inbox, provided by VK LLC under its terms. Your chosen messenger also processes messages under its rules. Payment organisations and the Russian Federal Tax Service receive information required for payment and tax obligations, including payment receipts. This site does not receive bank card details.
Personal data is not sold and correspondence is not published. Necessary operations include collection, recording, storage, correction, use, transfer, restriction and destruction. Work uses electronic correspondence with human involvement; no proprietary CRM or automated mailing is used.
Retention and protection
Enquiry data is used until discussions or the order are completed, then destroyed within the time limits of Article 21 of Law No. 152-FZ unless a contract or law provides another retention basis. Required payment and tax records are retained for statutory periods, limited to the data necessary for that purpose.
Temporary contact request counters are held in service memory, not written by it to a database. Hosting logs depend on the actual hosting configuration. Access to working email and documents is restricted. Contact endpoints apply rate limits; public deployment provides HTTPS. Ask the operator about actual hosting, recipients and retention. Not all external service data is stored on the website server.
Your rights
You may request processing information, correction, restriction or destruction where applicable, and withdraw consent. Write to or the postal address above with enough information to identify your data and verify your entitlement. Articles 20–21 of Law No. 152-FZ govern response deadlines.
Withdrawal stops processing based on consent; statutory contract, payment and record-keeping obligations may continue. You may complain to Roskomnadzor or a court. The current policy is publicly accessible and is updated when processing changes.
