Privacy Policy

Last updated: 25 June 2026

1. Data controller

The controller of personal data collected through devsentinel.pl is devsentinel Krzysztof Jaroński, ul. Wiosenna 22 lok. 1, 83-032 Skowarcz, Poland, tax ID (NIP): 9571051805 (the “Controller”).

For data protection matters, contact the Controller at kontakt@devsentinel.pl or via the contact form on the homepage.

2. Scope and purposes of processing

2.1. Contact form and email correspondence

When you submit the contact form or email us, we process the data you provide: name, email address, phone number (if provided — this field is optional) and message content.

Purpose: responding to your inquiry, preparing an offer or establishing cooperation.

Legal basis: your consent (Art. 6(1)(a) GDPR) — given via the form checkbox — and the Controller’s legitimate interest in handling correspondence (Art. 6(1)(f) GDPR) when you contact us directly by email.

2.2. Offer assistant (on-site chatbot)

The interactive assistant on the homepage collects answers only in your browser during the current session. After the conversation, answers may be inserted into the contact form message field — they are then processed like form data (section 2.1), after your consent to submit the form.

The assistant does not require registration or login and does not store conversations on the Controller’s server.

2.3. IT security quiz

The self-assessment quiz runs locally in your browser. Results are not automatically sent to the Controller — unless you choose to contact us (e.g. via the form) and describe your situation.

2.4. Technical data and logs

When using the site, technical data necessary for operation and security may be processed: IP address, date and time of request, browser type, operating system, visited URL.

Purpose: ensuring proper site operation, error diagnostics, abuse prevention.

Legal basis: legitimate interest of the Controller (Art. 6(1)(f) GDPR).

3. Retention period

Contact form and correspondence data are kept for as long as needed to respond and handle the inquiry, no longer than 24 months from the last contact, unless you withdraw consent or object earlier.

After that period, data is deleted or anonymised unless law requires longer retention.

Technical logs are kept as long as necessary for security purposes — typically up to 12 months.

4. Your rights

You have the right to: access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), data portability (Art. 20), object (Art. 21), and lodge a complaint with the Polish Data Protection Authority (UODO).

Where processing is based on consent, you may withdraw it at any time by contacting the Controller. Withdrawal does not affect the lawfulness of processing before withdrawal.

5. Recipients and subprocessors

6. Transfers outside the EEA

We use services of entities located outside the European Economic Area (e.g. EmailJS, Google). Transfers comply with GDPR requirements — in particular Standard Contractual Clauses (SCC) or other lawful mechanisms.

7. Cookies and local storage

DevSentinel uses cookies and local storage in the categories below. You choose optional categories in the cookie banner on first visit or anytime via “Cookie settings” in the footer.

Essential — required for the site, security, contact forms and remembering your cookie decision. Always active; no separate consent required.

Analytics — help understand traffic (e.g. Google Analytics, Ahrefs Analytics — if configured). Used only after your consent. Analytics is off by default (Google Consent Mode v2). Offer-assistant conversation content is not sent to analytics tools as analytics data.

Functional — remember interface preferences (e.g. language, light/dark mode). Active only after your consent.

Advertising — technically prepared for the future (campaign measurement, remarketing). Not active until we enable ad tools and this category in the cookie banner.

You can change your decision anytime via “Cookie settings” in the footer. After withdrawing analytics consent, known Google analytics cookies are cleared in the browser where possible.

8. Security

We apply technical and organisational measures appropriate to the risk (including HTTPS, access restrictions, contractor agreements). In case of a personal data breach, we act in accordance with Arts. 33–34 GDPR.

9. Policy changes

This policy may be updated due to legal or operational changes. Material updates will be announced on devsentinel.pl. The current version is always available at this address.
