Terms of Service

1. Acceptance of Terms

By accessing or using dankcharts.fm (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, please do not use the Service.

These Terms constitute the entire agreement between you and Erwin Solorzano ("I", "me", "the operator"), an individual operating from Guatemala, regarding your use of the Service.

2. About the Service

dankcharts.fm is a personal music chart visualization tool. Core features are free. Some features may be designated as premium (paid) at any time, and the availability or pricing of any feature is subject to change without notice. It lets you explore your listening history by connecting to:

• Last.fm — your scrobble history is fetched directly from Last.fm's public API using your username.
• Google Sheets — you provide a publicly shared spreadsheet URL; the Service reads it on your behalf.
• File upload — you upload a local CSV, ZIP, or XLSX file directly in your browser.

Optional Google Sign-In allows the Service to remember your setup preferences (e.g., sheet URL, theme, language) across sessions using Firebase.

3. Eligibility

You must be at least 13 years old to use the Service. If you are under 16 (or the applicable age of digital consent in your country), you must have parental or guardian consent. By using the Service, you confirm you meet these requirements.

4. Privacy

Your privacy is important to us. How we collect, use, store, and protect your personal data — including your rights under GDPR, CCPA, and other applicable laws — is covered in full in our dedicated Privacy Policy.

By using the Service, you acknowledge that you have read and understood the Privacy Policy. It forms part of these Terms by reference.

5. Intellectual Property

The dankcharts.fm name, logo, and original code are owned by Erwin Solorzano. All rights reserved.

Your music listening data remains entirely yours. We claim no rights over data you import into the Service. Chart images and exports you generate are yours to use freely.

Last.fm, Spotify, Apple Music, Google, and other third-party names and logos are trademarks of their respective owners. Their use on this site is for identification purposes only and does not imply endorsement.

6. Disclaimers & Limitations

The Service is provided "as is" without warranties of any kind, express or implied. To the fullest extent permitted by law:

• We do not warrant that the Service will be uninterrupted, error-free, or secure.
• We are not responsible for the accuracy or availability of data provided by Last.fm or Google Sheets.
• We are not responsible for changes to third-party APIs (Last.fm, Google) that may affect the Service.
• We shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service.

Nothing in these Terms limits liability that cannot be excluded under applicable law (including consumer protection laws in your jurisdiction).

7. Acceptable Use

You agree not to:

• Attempt to reverse-engineer, scrape, or abuse the Service in ways that harm its availability for other users.
• Use the Service to infringe the rights of Last.fm, Google, or any other third party.
• Misrepresent your identity or provide false information during sign-in.
• Use the Service for any unlawful purpose.

8. Changes to These Terms

We may update these Terms from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

For material changes, we will make reasonable efforts to notify signed-in users (e.g., via a notice on the landing screen).

9. Governing Law

These Terms are governed by and construed in accordance with the laws of Guatemala. Any disputes arising from these Terms or your use of the Service shall be subject to the exclusive jurisdiction of the competent courts in Guatemala.

If you are a consumer located in the European Union or United Kingdom, you retain the right to bring proceedings before the courts of your country of residence under applicable consumer protection laws.
