# Privacy policy
Last updated · 3 September 2026 · v1.1
This policy describes what data Siere Soft LTD collects about visitors to sieresoft.com and how we use it. It is drafted in plain English on purpose. Where we say "we", we mean **Siere Soft LTD**, a company registered in Bulgaria (EIK 206672583).

## 1 · What we collect

We collect three categories of information, and nothing else.

### a · Analytics

If you accept analytics cookies, we use Firebase Analytics, powered by Google Analytics, to understand how the site is used. It may process pages visited, interactions, referrer, approximate location, device and browser information, and online identifiers. We do not load Analytics if you reject it.

### b · The AI advisor

If you choose to open the chat widget, we store the messages you send for up to **30 days**, after which they are deleted. We use them to improve the advisor and to investigate abuse. Conversations are stored against an opaque session id, not a personal identifier — but please don't share data you wouldn't share over email.

### c · Contact forms & email

If you submit the contact form or write to us, we receive your name, email, and message. We use it to reply to you. We don't add you to any list and we don't have a marketing automation tool.

## 2 · Cookies

We set the necessary `ss-cookie-consent` cookie after you accept or reject analytics, so we can remember your choice. If you accept, Firebase and Google Analytics may set analytics cookies and similar identifiers. If you reject, Analytics is not loaded. The AI advisor uses a short-lived session token bound to the browser tab and not persisted.

## 3 · Legal basis

Where the EU GDPR requires a basis, we rely on your consent for Firebase Analytics. For the small amount of operational data described above, our basis is legitimate interest. For the AI advisor and contact form, the basis is your consent and the performance of pre-contractual steps at your request.

## 4 · Sharing

We share data only with the processors we need to run the site: Vercel (hosting), Cloudflare (edge security and Turnstile), Google (Firebase and Analytics, with your consent), Anthropic (the chat advisor's model provider), Resend (email delivery), Upstash (rate-limit data), and Sentry (error tracking). We do not sell data and we do not share it with third-party advertisers, because we don't run ads.

## 5 · International transfers

Some of our processors are based outside the EEA. Where so, transfers are made under the EU Standard Contractual Clauses.

## 6 · Your rights

Under EU data protection law you can request access to, correction of, or deletion of, the personal data we hold about you. Email [privacy@sieresoft.com](mailto:privacy@sieresoft.com) and we'll respond within a calendar month, usually within a working week.

## 7 · Retention

- Chat advisor conversations: **30 days**
- Contact form submissions: retained while a working relationship is plausible, otherwise deleted after 12 months
- Analytics: according to the retention period configured in Firebase and Google Analytics
- Sent invoices and contracts: 10 years (Bulgarian accounting law)

## 8 · Complaints

If we've not resolved a privacy issue to your satisfaction, you can complain to your local EU data protection authority.
