Privacy Policy
Analytics & Usage Data
This website uses Vercel Web Analytics to collect aggregated, anonymous data on how visitors use the site. This data is used solely to understand which documentation pages are visited most frequently and to improve the quality and accessibility of the documentation over time.
What Data is Collected
When you visit this site, Vercel Web Analytics automatically records the following information for each page view: the timestamp of the visit, the URL and path of the page visited, the referring URL (the page you came from), filtered query parameters, an approximate geographic location derived from your IP address (country, region, and city), your device operating system and version, your browser name and version, and your device type (desktop, mobile, or tablet). This information is stored in aggregated, anonymized form. No personal identifiers — such as your name, email address, or IP address in full — are stored or associated with any recorded data point.
Cookies and Tracking Identifiers
Vercel Web Analytics does not use cookies or any persistent tracking identifiers. Visitors are identified using a temporary, anonymized hash derived from the incoming request, which is automatically discarded after 24 hours. This means that your visit cannot be tracked across sessions or across other websites.
Legal Basis for Processing (GDPR)
For visitors located in the European Economic Area (EEA), the United Kingdom, or Switzerland, the legal basis for this data processing is Legitimate Interests under Article 6(1)(f) of the General Data Protection Regulation (GDPR). The legitimate interest pursued is understanding how the documentation is used in order to improve it — a purpose proportionate to the minimal, anonymized data collected, and one that does not override the fundamental rights and freedoms of visitors.
Third-Party Data Processor
This website is hosted on and analytics are provided by Vercel, Inc., located at 340 Pine Street, 5th Floor, San Francisco, CA 94104, USA. Vercel acts as a data processor on behalf of this site. Vercel is certified under the EU-U.S. Data Privacy Framework, which provides an adequate level of data protection for personal data transferred from the EU, UK, and Switzerland to the United States. For more information, see Vercel's Privacy Policy and Vercel's Analytics Privacy & Compliance documentation.
Data Retention
Vercel Web Analytics retains aggregated analytics data in accordance with Vercel's data retention policies. Because data is collected and stored only in anonymized, aggregated form, it cannot be linked back to any individual and is not subject to individual deletion requests. Visitor session hashes are automatically discarded after 24 hours.
Your Rights
Depending on your location, you may have rights regarding personal data under applicable law, including the right to access, correct, or request deletion of personal data held about you. Because this site collects only anonymized, aggregated analytics data that cannot be linked to any individual, these rights cannot be practically exercised against this data. For any privacy-related questions or concerns, you may contact the Poiyomi Shaders team via the project's official community channels.
Changes to this Policy
This Privacy Policy may be updated from time to time to reflect changes in the tools used on this site or to comply with updated legal requirements.
