Privacy Policy
Last updated: July 10, 2026
This policy explains how Devs 3.0 processes the personal data of people using devs30.com, in particular newsletter subscribers.
Data controller
The data controller is IT-OPES Usługi Informatyczne, NIP PL5291686297. For matters concerning personal data, contact us at .
What data we collect
When you subscribe to the newsletter we collect your email address. We do not collect other personal data through the newsletter form.
Purpose and legal basis
We process your email solely to send the newsletter, based on your consent (Art. 6(1)(a) GDPR). You confirm consent via double opt-in and can withdraw it at any time.
Processors
We use the provider Resend (resend.com) to send messages. We use Google Analytics 4 (Google Ireland Limited) to measure site traffic. Data may be processed on these providers' infrastructure solely for the described purposes.
Cookies and analytics
The site uses Google Analytics 4 to measure traffic and visit statistics. We collect statistics only after you consent to cookies (art. 6(1)(a) GDPR). Until you consent, analytics runs without cookies. Data may be processed by Google outside the European Economic Area. You can withdraw consent at any time via the Manage cookies link in the footer.
Retention period
We keep your email address until you withdraw consent or unsubscribe, after which we remove it from the list.
Your rights
You have the right to access, rectify, erase, and restrict processing of your data, and to withdraw consent. To exercise these rights, write to .
User account
When you maintain an account we process your email address, display name, optionally your first and last name, timezone, and records of login sessions and terms acceptance. We process this data to provide the account and the user dashboard, based on contract performance (Art. 6(1)(b) GDPR). We keep the data until the account is deleted, which irreversibly anonymizes personal data.
Signing in with Google and GitHub
When you choose to sign in with Google or GitHub, the provider shares the account identifier, email address and name with us. Devs 3.0 stores only the link to that identifier, the email address and the name, without any passwords held by the provider. Login tokens are not retained beyond the login process itself.
