Privacy Policy

Effective from 11 September 2026

This Policy explains what personal data we collect when you use portal-diagnostov.com, why we collect it, who we share it with and what rights you have. We keep it short and specific: it describes what this website actually does, not what a template says.

1. Who we are

We operate this website and decide how the personal data described below is processed. For any question about your data, write to the address above — that mailbox is read by a person.

2. What we collect

• Email address — you enter it to sign in. We sign you in with a one-time code sent to that address, so the address has to be real and it identifies your account and your purchases.
• Name and profile picture — only if you choose to sign in with Google. We receive them from Google together with your verified email address. We never receive your Google password.
• Phone number — only if you give it to us yourself.
• Purchase and access records — which vehicle a payment opened access to, order number, date and amount.
• Payment status — we receive from our payment provider the fact that a payment succeeded or failed, the amount and the last digits of the card. We never receive or store full card numbers. Card details are entered on the payment provider's form and never reach our servers.
• Technical data — IP address, browser and device type, pages opened, dates and times. Web servers record this automatically.
• Cookies — see section 9.

3. Why we use it

• to sign you in and keep you signed in;
• to give you access to the wiring diagrams you paid for, for as long as your account exists — access is sold once and is not time-limited;
• to take payment and to send you the receipt;
• to answer your questions in support;
• to detect and prevent fraud and abuse of paid access;
• to see which pages are used and where the site fails, so we can fix it.

4. On what legal basis

• Performance of a contract — signing you in, giving access to what you bought, taking payment, support.
• Legitimate interest — security of the service, fraud prevention, keeping server logs.
• Your consent — analytics and marketing cookies. You give it in the cookie banner and can withdraw it at any time.

5. Who we share it with

We do not sell personal data and do not pass it to anyone for their own marketing. We share it only with the services that make this website work:

• Stripe — payment processing. Receives the amount, order number and your email address for the receipt.
• PayPal — payment processing, where you choose it.
• Google — if you sign in with Google, and Google Analytics (G-CG6J69LDDL) for usage statistics.
• Yandex — Yandex Metrica (counter 57528007) for usage statistics, and Yandex Cloud as our hosting and email provider.

These companies process the data under their own privacy policies and only for the purpose we pass it to them for.

6. Where it is processed

The website runs on servers rented from Yandex Cloud, in data centres located in Russia. Payment data is processed by Stripe and PayPal on their own infrastructure, outside our servers.

7. How long we keep it

• Account and purchase records — while your account exists. Access to purchased material is lifetime, so we have to keep the record of what you bought in order to keep giving you that access.
• Payment records — as required by accounting and tax rules.
• Server logs — a short period, then they are deleted automatically.

If you ask us to delete your account, we delete your personal data, and with it the access you bought. That cannot be undone.

8. Your rights

• to know what data we hold about you and get a copy;
• to have it corrected;
• to have it deleted;
• to withdraw consent to analytics cookies at any time;
• to object to processing based on legitimate interest.

Write to support@portal-diagnostov.com from the address your account is registered to. We answer within 30 days.

9. Cookies

We use two kinds:

• Necessary — they keep you signed in and remember your cookie choice. Without them the site cannot work, so they are set without asking.
• Analytics — Google Analytics and Yandex Metrica. They are set only after you agree in the banner.

You can change your choice at any time in the cookie banner, or delete cookies in your browser settings.

10. How we protect it

• all traffic is encrypted (HTTPS/TLS);
• passwords are stored hashed, and sign-in normally works without a password at all — by a one-time code or through Google;
• administrative access is restricted by IP address and SSH keys;
• card details never reach our servers;
• regular backups and security logging.

11. Children

The site is intended for professional and adult users. We do not knowingly collect data from children under 16. If you believe a child has given us personal data, write to us and we will delete it.

12. Changes to this Policy

If we change how we handle personal data, we update this page and change the effective date at the top. Material changes will also be announced on the site.
