Privacy policy

Last updated: 22 August 2026

1. Who we are

The controller of your personal data is [юридическо лице — попълни преди launch], company ID (ЕИК) [ЕИК — попълни], with its registered office and address of management at [седалище и адрес — попълни] (platform under the “Selurio” trademark). Contact for privacy questions: [имейл за контакт — попълни].

2. What data we collect and why

Newsletter: email address and sign-up date — used to send an educational newsletter. Legal basis: your consent. Retention: until you unsubscribe.

Traffic analytics: anonymous, aggregated data (visits, browser type, country, referrer) — used to improve our content. Legal basis: legitimate interest (no cookies). Umami Cloud retains this data for up to 6 months.

Calculator usage logging: the calculator’s slug and a timestamp, with no personal data — used for popularity statistics. Legal basis: legitimate interest.

3. Who we share data with

We use processors (subprocessors) for hosting (Vercel), the database (Neon) and transactional emails (Resend). All of them have signed data processing agreements (DPAs) and comply with the GDPR requirements for data transfers.

We use Umami Cloud for traffic analytics. Financial values entered into calculators and email addresses are not sent to this service.

4. Your rights (GDPR)

You have the right to:

  • access — a copy of the personal data we hold about you;
  • rectification of inaccurate data;
  • erasure (the right to be forgotten);
  • portability — your data in a machine-readable format;
  • objection to processing based on legitimate interest;
  • withdrawal of consent to the newsletter at any time;
  • complaint — to lodge a complaint with the competent data protection authority (in Bulgaria, the Commission for Personal Data Protection (CPDP), kzld.bg).

To exercise these rights: [имейл за контакт — попълни]. We respond within 30 days.

5. Cookies

The core version of the site does not use cookies for tracking or analytics — Umami and Vercel Analytics work without cookies. The only exception is opt-in: if you choose to load the live market charts (TradingView) on the home page, the provider sets its own third-party cookies — this never happens without your explicit consent. If this changes in the future, we will ask for your consent through a cookie banner.

6. Security

We apply appropriate technical and organizational measures — encryption in transit (HTTPS) and encrypted storage of the database.

7. Changes

We may update this policy. Material changes are announced with 30 days’ notice on the site.
