Privacy Policy

This Privacy Policy explains how Chartline handles information when you visit chartlinehits.com. Chartline is an independent music-chart research platform.

Information you provide

Chartline does not currently require user accounts, purchases or payment information. Search terms that you enter are used to return relevant songs and artists. Search terms may appear in the page URL and may therefore be retained in your browser history or routine server logs.

If Chartline later activates features that collect contact information, such as a working newsletter signup or contact form, this policy will be updated before that collection begins.

Technical and usage information

When you visit Chartline, hosting and infrastructure providers may process ordinary technical information needed to deliver and protect the website. This may include an IP address, approximate location derived from an IP address, browser and device information, requested pages, referring page, timestamps, performance information and diagnostic logs.

Analytics

Chartline uses Vercel Web Analytics and Google Analytics 4 to understand website traffic, measure engagement, identify how visitors find the site and improve Chartline's content and performance.

Google Analytics may collect or derive information such as pages viewed, referring pages or campaigns, approximate geographic location, browser and device characteristics, timestamps and interactions with the website. Google Analytics may use cookies or similar technologies to distinguish browsers and measure visits. Chartline has enabled IP anonymization in its Google Analytics configuration and does not currently use Google Analytics to serve personalized advertising.

Analytics information is generally reviewed in aggregate. Google processes Analytics data according to its own terms and privacy practices. You can learn more about how Google uses information from sites that use its services on Google's partner sites information page and in the Google Privacy Policy.

Vercel describes Web Analytics as privacy-focused and designed without cookie-based visitor tracking. Vercel may still process technical request and usage information as part of hosting and providing its services. You can learn more in the Vercel Privacy Notice.

Spotify embeds

Some Chartline pages include embedded Spotify players. Loading or interacting with a Spotify player connects your browser directly to Spotify. Spotify may receive technical information and may use cookies or similar technologies according to its own policies. Chartline does not control Spotify's data practices.

You can review the Spotify Privacy Policy.

Database infrastructure

Chartline uses Supabase to provide database infrastructure for chart, song and artist information. Requests needed to retrieve site content may be processed through Supabase infrastructure.

You can review the Supabase Privacy Policy.

Cookies and browser controls

Chartline does not currently use cookies to serve personalized advertising. Google Analytics and third-party content such as Spotify embeds may use cookies or similar browser storage for measurement, security or functionality. You can limit or delete cookies through your browser settings, although doing so may affect analytics accuracy or embedded-player functionality.

How information is used

Technical and aggregate usage information may be used to operate, secure, troubleshoot and improve Chartline; measure general traffic patterns; prevent misuse; and comply with applicable legal obligations.

Sharing and disclosure

Chartline does not sell personal information. Information may be processed by service providers that support website hosting, analytics, databases and embedded media. Information may also be disclosed when reasonably necessary to comply with law, protect rights or security, or investigate misuse.

Data retention and security

Technical records are retained only as reasonably necessary for website operations, security, troubleshooting and legal obligations, subject to the practices of Chartline's service providers. No method of online transmission or storage is completely secure.

Children's privacy

Chartline is a general-audience music-history website and is not directed to children under 13. Chartline does not knowingly collect personal information from children.

Your choices

You may use browser settings or privacy tools to limit or delete cookies and block third-party content. Google also provides a Google Analytics opt-out browser add-on. You may also choose not to interact with embedded Spotify players.

Changes to this policy

This policy may be updated as Chartline adds or changes features and service providers. The effective date at the top of this page will be revised when material changes are published.

Contact

Chartline does not currently maintain a public privacy-contact inbox. Contact information will be added to this page when a dedicated address becomes available.
