Koderka Website Privacy Policy

This policy covers the website koderka.com: reading it, the contact form, emails to support@koderka.com and the newsletter. Each app has its own privacy policy, linked from the app’s page.

The controller of your personal data is Koderka Łukasz Nawrocki, Adama Logi 17/1, 60-134 Poznań, Poland, NIP 7792359653. Koderka is the name I publish my apps under. You can reach me at support@koderka.com.

When you send a message through the contact form, I receive your email address, your name if you give it, the topic you chose, your message, the page you sent it from and the time. When you write to support@koderka.com directly, I receive your email: your email address, your name as your email shows it, your message, anything you attach and the time.

• Purpose: to answer you.
• Legal basis: my legitimate interest in answering messages, and steps you ask me to take (Article 6(1)(f) and 6(1)(b) GDPR).
• How long: in my mailbox until the matter is closed, and for up to 2 years after that.

When you subscribe, I keep your email address, the time you confirmed and the page you signed up on.

• Purpose: to send you an email when I publish a new post.
• Legal basis: your consent (Article 6(1)(a) GDPR). You confirm it with the link in the confirmation email.
• How long: until you unsubscribe. I then delete your address within 30 days. If you never confirm, your address isn’t added to the list; it stays only in the email service’s record of the confirmation email it sent.

The newsletter is for people aged 16 or over.

The site uses Cloudflare Web Analytics. It counts page views in aggregate, without cookies and without identifying you. I can see how many people read a page, not who they are.

• Legal basis: my legitimate interest in knowing which pages people read (Article 6(1)(f) GDPR).
• How long: Cloudflare keeps the aggregated counts under its own retention rules; I keep no copies.

The forms use Cloudflare Turnstile to tell people from bots. Cloudflare processes technical data about your browser and connection for this check. Turnstile loads only when you start filling in a form.

• Legal basis: my legitimate interest in keeping the forms free of spam (Article 6(1)(f) GDPR).
• How long: only for the check; I receive a pass or fail result, not the data.

To stop floods of messages, the site counts form submissions per IP address for one minute. When a form is used, the site’s log records which form, the outcome, any error code, the email service’s message ID and a short code derived from your email address (the first 8 characters of its SHA-256 hash), never your message or full address.

• Legal basis: my legitimate interest in running and protecting the forms (Article 6(1)(f) GDPR).
• How long: the counters reset after a minute; the logs are kept by Cloudflare for a few days.

Cloudflare, which hosts the site, keeps technical logs of requests (such as IP address, time and the page requested) to run and protect the service.

• Legal basis: my legitimate interest in running a secure website (Article 6(1)(f) GDPR).
• How long: for the short time Cloudflare keeps them; I don’t keep copies.

• Cloudflare, Inc. hosts the site and provides DNS, email forwarding, Web Analytics and Turnstile.
• Resend, Inc. sends the site’s emails (contact form notices and newsletter emails), keeps a record of the emails it sends, and keeps the newsletter list. It sends koderka.com’s emails from servers in the EU (Ireland).
• Google stores the mailbox where contact form messages, and emails you send to support@koderka.com, arrive and where I answer them.

I don’t sell your data or share it for advertising.

Cloudflare, Resend and Google may process data outside the European Economic Area, including in the United States. Where they do, the transfer relies on the EU–US Data Privacy Framework or on the European Commission’s Standard Contractual Clauses.

Koderka’s pages set no cookies and store nothing in your browser.

You have the right to:

• access the data I hold about you,
• have it corrected,
• have it deleted,
• restrict how I use it,
• object to how I use it,
• receive it in a portable format,
• withdraw your consent at any time, without affecting what happened before.

To use any of these rights, write to support@koderka.com or use the contact form and choose “Privacy request”. I answer within one month.

You can complain to the Polish supervisory authority, the President of the Personal Data Protection Office (Prezes UODO), at uodo.gov.pl, or to the authority in the EU country where you live or work.

The newsletter is for people aged 16 or over. The site isn’t aimed at children.

When this policy changes, I publish a new version with a new effective date. Earlier versions stay online, linked from this page.

To ask about your data or this policy, write to support@koderka.com.
