1. Who is responsible for your data

The data controller is Oleksandr Kazmirchuk, the operator of Devs Hive. For any privacy question or request, write to akazmirchik@gmail.com.

2. What we collect

• Account data. When you sign in with Google or GitHub, we receive your name, email address, profile photo and a unique account identifier from that provider. We never see your password.
• Profile and settings. Your display name, preferred content language, email notification preferences and whether you appear on public quiz leaderboards.
• Learning activity. Interview questions you mark as known or seen, question lists, course enrollments and lesson progress, quiz attempts and scores, article likes and comments.
• Content you submit. Articles and interview questions you write, and moderation decisions about them.
• Messages. When you use the contact form, we receive your name, email address and message.
• Account deletion feedback. If you delete your account, the reason you choose and any comment you add.
• Technical data. IP address, browser and device type, pages visited and error reports, collected through the analytics and monitoring tools described below.

3. How we use it

We process data to provide the service you asked for (performance of a contract), based on our legitimate interest in running and improving the site securely, and on your consent for analytics cookies. We do not sell your personal data and do not use it for advertising.

• To sign you in and keep your account secure.
• To save your learning progress, lists, quiz results and submitted content.
• To send service emails: a welcome email, updates about content you submitted, and notifications about new courses or features. You can turn off notification emails in your profile.

• To understand how the site is used and to find and fix errors.

4. Cookies and similar technologies

The cookie banner is provided by CookieYes. You can change your choice at any time through the banner or by clearing cookies in your browser.

• Essential cookies keep you signed in and remember your language. The site cannot work without them.
• Analytics cookies from Google Analytics for Firebase help us see which pages are useful. They are used only according to the choice you make in the cookie banner.
• Local storage in your browser remembers small things, such as banners you have dismissed.

5. Who we share data with

We use trusted service providers that process data on our behalf and only to run the site:

• Google Firebase - sign-in and analytics.
• Google and GitHub - when you choose them to sign in.
• Neon - database hosting.
• Vercel - website hosting.
• Mailgun - sending emails.
• Sentry - error monitoring. When an error occurs, Sentry may record a replay of the session with text and inputs masked.
• CookieYes - cookie consent management.

6. What other people can see

If you publish an article or interview question, your name is shown as its author. Your name and score may appear on public quiz leaderboards; you can opt out in your profile. Everything else, including your email address and learning progress, is private.

7. International transfers

Some of our providers store data outside your country, including in the United States. Where required, transfers are protected by Standard Contractual Clauses or equivalent safeguards offered by those providers.

8. How long we keep data

We keep your data while your account is active. When you delete your account in your profile, your sign-in account is removed immediately and your profile is deactivated. Remaining records are kept only as long as needed for security, legal obligations or published content you authored; you can ask us to erase them completely by email. Contact form messages are kept only as long as needed to handle your request.

9. Your rights

Depending on where you live, including under the EU GDPR, you have the right to access your data, correct it, delete it, restrict or object to its processing, receive a copy in a portable format, and withdraw consent at any time. To use any of these rights, write to akazmirchik@gmail.com. You also have the right to lodge a complaint with your local data protection authority.

10. Children

Devs Hive is not intended for children under 16. We do not knowingly collect data from them. If you believe a child has given us personal data, contact us and we will delete it.

11. Security

Data is transmitted over HTTPS, access to systems is restricted, and sign-in is handled by Firebase, so we never store passwords. No method of storage or transmission is completely secure, but we work to protect your data.

12. Changes to this policy

We may update this policy when the site changes. The date at the top shows the latest version. If changes are significant, we will let you know on the site or by email.
