• User accounts: identity fields, role, password hash, language preference, status, and timestamps.
• Educational product data: enrollments, challenge submissions, course progress, section mistakes, badges, and profile content.
• Lab project posts: project titles, descriptions, links, tech stacks, uploaded images, visibility settings, and information about your membership in spaces.
• Public profile and signal data: only the profile, portfolio, and visibility fields that a user explicitly leaves in public mode.
• Authenticated feedback submissions: three product ratings, optional comment, device/browser context, locale, and account activity snapshot at submit time.
• Operational data: invite tokens, tenant audit logs, API telemetry, and limited security metadata.
• Billing data for Learner Pro: Stripe customer identifier, subscription state, trial and payment lifecycle events, invoices, and basic billing metadata.
• Optional public-site analytics after consent: first-party visit/conversion events and Google Analytics public-marketing page views, sessions, referrer origin, device/browser, and approximate-location measurement. Query parameters and sensitive authentication routes are excluded.

• Accounts, invites, authentication, and transactional emails: steps prior to a contract and legitimate interests in operating the service securely.
• Educational progress, challenge review, and platform operations: legitimate interests in delivering the product to learners, mentors, and any organizations that operate private spaces on Hackode.
• Authenticated product feedback: legitimate interests in improving product usability, reliability, and rollout decisions with account-linked context.
• Billing, trial, promo grants, and subscription management through Stripe: performance of a contract and legitimate interests in operating paid Learner Pro access.
• Security, audit trails, abuse prevention, and incident investigation: legitimate interests and, where applicable, legal obligation.
• Optional public-site analytics cookies and visitor-level telemetry: consent.

• The public site and product run on a self-managed Ubuntu VPS operated through VDSina in Amsterdam, Netherlands.
• The PostgreSQL database, backups, and application runtime are currently operated on the same VPS environment.
• Application/runtime logs live on the VPS host, while API telemetry and product telemetry are also stored in PostgreSQL tables.
• Profile avatars and banners use Vercel Blob when blob storage is configured in the environment.
• Learner Pro billing and subscription processing run through Stripe under the current Slovakia-linked merchant setup.
• Google AI processing is configured for Europe-region workloads in the current deployment.
• Google Analytics processes optional website measurement only after analytics consent is granted.

Hackode shares data only with infrastructure and delivery providers needed to run the product.

• VDSina: Infrastructure hosting for the public site, application runtime, database, backups, and host-level logs. Data shared: Account data, demo requests, educational progress data, audit logs, and operational metadata stored on the VPS. Region / transfer note: Amsterdam, Netherlands. The current deployment VPS is operated through VDSina. A specific hosting region is published only if explicitly confirmed in deployment configuration.
• Google Gemini: AI generation for course hints, mentor sessions, and challenge autofill routes. Data shared: Prompt content, challenge/course context, and limited request metadata needed to produce the response. Region / transfer note: Europe-region processing. The current deployment is configured to use Europe-region processing for Google AI workloads. Any later processor-region change must be reflected in the legal surface before rollout.
• Google Analytics: Optional website audience and page-view measurement after analytics consent. Data shared: Public marketing pathname and title without query parameters, referrer origin, device/browser metadata, approximate location derived by Google, and GA4 client/session identifiers. Region / transfer note: Google-managed analytics infrastructure. Google may process analytics data internationally under its Google Ads Data Processing Terms and applicable transfer safeguards. The tag is blocked until analytics consent is granted.
• Vercel Blob: Public object storage for profile avatars and banner uploads. Data shared: User-uploaded profile images and the public URLs generated for those assets. Region / transfer note: Vercel-managed object storage. Blob storage is active in the current environment for public asset uploads and delivery.
• Resend: Transactional email delivery for auth, demo, and privacy emails. Data shared: Recipient email address, sender address, message subject, and message body for invite/demo/privacy emails. Region / transfer note: Resend-managed infrastructure. Configured in the current environment for transactional email delivery.
• Stripe: Payment processing for Hackode billing flows. Data shared: Email, customer identifier, subscription metadata, billing status, and payment lifecycle events. Region / transfer note: Slovak merchant account region with Stripe-managed infrastructure. The current merchant setup is treated as Slovakia-linked for billing operations. Stripe may still process data through its managed infrastructure according to Stripe terms.

• Public visit analytics events: 90 days.
• Product telemetry events: 180 days.
• API request telemetry: 14 days in raw event form, with aggregated operational statistics retained separately.
• Tenant audit logs: 365 days, then retention review unless a security or legal-defense exception applies.
• Privacy requests and cookie consent records are retained while operationally or legally necessary and then reviewed under the retention schedule.
• Feedback submissions: retained while the product team still needs the signal for product operations, trust, and support review, then reviewed under the retention schedule.
• User account and educational records: kept while the account or any linked organization relationship is active. After that, the data is either deleted on request (via the privacy request flow), removed on our regular retention schedule, or kept longer only if the law requires it.

• Only the profile and portfolio fields that a user explicitly leaves in public mode should appear in the public learner profile.
• If a user switches the profile back to private mode, that profile should no longer be publicly discoverable as a public learner signal.
• Public leaderboards and other public signal surfaces should respect the current visibility state of the profile.
• If watcher-organization or company-specific visibility layers are added later, they must be explained both in-product and in this policy.

• Hackode self-serve signup is intended for users aged 13+.
• If a user is under 18 and joins through the direct self-serve flow, that user must have permission from a parent or legal guardian.
• The platform is moderated for a 13+ audience, but Hackode does not currently operate a fully polished direct-to-child parent-consent workflow.
• Where minors are involved through mentor-led or organization-led onboarding, that organization or another responsible adult context must provide the lawful-basis layer and supervision context.
• If a stronger direct child-consent flow is introduced later, this policy and the product flow must be updated before launch.

• You may request access, rectification, erasure, restriction, objection, or portability of data.
• Send privacy requests to [email protected].
• Hackode verifies identity before acting on sensitive requests.
