It collects aggregated, anonymous usage metrics such as page views, referrers, and browser information. No personal information is stored or processed, and no tracking cookies are set.

Contact form

When you submit a message through the contact form, the information you provide (name, email address, and message) is transmitted securely and used solely to respond to your enquiry. It is not stored in a database, not used for marketing purposes, and not shared with any third party. The email is delivered via a Cloudflare Worker and is not retained after delivery.

Local storage

A single theme key is stored in your browser's localStorage to remember your light or dark mode preference. This value never leaves your browser and is not transmitted to any server. No tracking cookies are used anywhere on this site.

External links

This site may contain links to external websites such as GitHub, LinkedIn, and Telegram. Once you follow a link to another site, this privacy policy no longer applies. Please review the privacy policies of those external services for information about how they handle your data.

Your rights

Under the General Data Protection Regulation (GDPR), you have the right to access, correct, or delete any personal information that may be associated with you. Since this site does not store personal details in any database, there is typically nothing to delete. However, if you have submitted a contact form message and wish to have it removed, please reach out and the request will be honoured promptly.

Changes to this policy

This privacy policy may be updated from time to time to reflect changes in services or legal requirements. The date of the most recent update is noted below. Continued use of the site after changes constitutes acceptance of the updated policy.
