Privacy Policy

To provide our services and improve your experience, we may collect the following categories of information when you submit it voluntarily or use the services:

If you contact us via forms, email, or social channels, we also store the content you provide so we can respond and follow up.

• Usage information: aggregated statistics such as visit times, pages viewed, referrers, browser and device types;
• Technical information: such as IP address, cookie identifiers, and local storage values used for security and preferences;
• Log information: server logs generated automatically to keep the service stable and to troubleshoot issues.

We use collected information only for the purposes below and only to the minimum extent necessary:

We do not sell your personal information to third parties and do not use it for automated decision-making unrelated to these purposes.

This site uses cookies and browser localStorage for essential functions, such as remembering your language preference (NEXT_LOCALE) and storing admin theme color and light/dark mode choices.

You can delete or block cookies in your browser settings. Please note that disabling essential cookies may break features such as language switching and theme memory.

We share personal information only in the following cases and require recipients to honor equivalent confidentiality and security obligations:

If personal information must be transferred due to a merger, acquisition, or asset sale, we will require the new holder to remain bound by this policy or notify you in advance.

• With your explicit consent or authorization;
• With trusted service providers needed to deliver the service (e.g., hosting, log analytics), under data-protection terms;
• When required by law, regulation, or judicial or administrative proceedings;
• When necessary to protect the lawful rights and interests of us, users, or the public.

We apply technical and organizational measures appropriate to the business (such as encryption in transit, access control, and least-privilege access) to protect personal information against unauthorized access, alteration, disclosure, or destruction.

Personal information is retained only as long as needed for the processing purposes. Where law provides otherwise, the law prevails. When the period ends, we delete or anonymize the data.

To the extent permitted by applicable law, you have the following rights regarding your personal information:

To exercise these rights, contact us using the details at the end of this policy. We may need to verify your identity for security.

This site may contain links to third-party websites or services (such as GitHub or social networks). Those third parties have their own privacy policies; we are not responsible for their practices. Please read their policies before leaving this site.

If third-party components are embedded (e.g., analytics scripts), we assess necessity before enabling them and prefer privacy-friendly options where possible.

Our services are intended for adults with full civil capacity. If we learn that we have collected a child's information inadvertently, we will delete it promptly.

If you are a guardian and believe a child has provided information to us, please contact us below so we can take action.

We may revise this Privacy Policy from time to time. Updated versions are published on this page with a new “Last updated” date.

If changes materially affect your rights or obligations, we will notify you through prominent means such as an on-site notice or email within a reasonable period.
