Privacy Policy

Last updated: 17 August 2026

This Privacy Policy explains how personal data is handled when you use Lyras Guitar Tools, available at lyras.app.

For the purposes of the General Data Protection Regulation (GDPR), Constantinos Lyras is the data controller where personal data is processed through this website.

1. About Lyras Guitar Tools

Lyras Guitar Tools provides free educational tools and resources for guitar students and musicians, including music theory exercises, chord practice, note-recognition exercises, rhythm tools, fretboard exercises and student resources.

Most of the educational tools can be used without creating an account or providing your name, email address, telephone number or other personal details.

2. Information Automatically Processed

Like most websites, the web server and security infrastructure used to provide Lyras Guitar Tools may automatically process limited technical information when you visit the website.

This may include:

• IP address
• Browser and device information
• Date and time of access
• Pages or resources requested
• Referring page
• Server, security and error-log information

This information may be processed to operate the website, maintain security, prevent abuse, diagnose technical problems and protect the website and its users.

The legal basis for this processing is our legitimate interest in operating and securing the website in accordance with Article 6(1)(f) GDPR.

3. Tool Data, Settings and Progress

Some interactive tools may temporarily process information that you enter or generate while using them, such as answers, scores, practice settings, preferences or progress.

Where a tool stores settings or progress locally in your browser or device, this information is used to provide the functionality of that tool.

Lyras Guitar Tools does not use practice results or tool activity for advertising or user profiling.

4. Student Resources

Some student resources may be protected by a password or other access-control mechanism.

Authentication and related technical information may be processed where necessary to:

• restrict access to authorised users;
• protect educational materials;
• maintain website security; and
• prevent unauthorised access or abuse.

Access credentials should not be shared with other people.

5. Cookies and Similar Technologies

Lyras Guitar Tools may use cookies or similar browser technologies where they are technically necessary for website functionality, security or access-controlled areas.

We do not use cookies for behavioural advertising.

If non-essential analytics, advertising or other tracking technologies are introduced in the future, this Privacy Policy and, where legally required, the website's consent mechanism will be updated accordingly.

6. Third-Party Websites and Services

Some pages on Lyras Guitar Tools contain links to external websites or services.

When you follow a link to another website, that website operates under its own privacy policy and data-processing practices. Lyras Guitar Tools is not responsible for the privacy practices of independent third-party websites.

You should review the privacy information provided by those services where appropriate.

7. Hosting and Technical Service Providers

The website may rely on hosting, network, security, font-delivery or other technical service providers in order to operate.

The website currently uses Google Fonts to provide its typography. When external resources are loaded, the relevant service provider may receive technical connection information such as an IP address, browser information and the resource requested.

Other hosting, network or security providers may also process limited technical information such as IP addresses and server requests where necessary to provide their services, maintain security and deliver website content.

Where service providers process personal data on our behalf, they are expected to process it only as necessary for the relevant service and in accordance with applicable data-protection requirements.

8. How Long Information Is Kept

Personal data and technical logs are retained only for as long as reasonably necessary for the purpose for which they were collected, including website operation, security, troubleshooting, prevention of abuse and compliance with legal obligations.

Retention periods may vary depending on the type of information and the service provider involved.

9. Children's Privacy

Lyras Guitar Tools is an educational website and may be used by children and younger music students.

The ordinary educational tools are designed so that students can generally use them without submitting personal information.

Children should not send personal information through the website unless necessary and, where appropriate, should do so with the involvement of a parent, guardian or teacher.

We do not knowingly use children's personal data for behavioural advertising or profiling.

10. Your Rights Under the GDPR

If personal data relating to you is processed by Lyras Guitar Tools, you may have rights under the GDPR, including the right to:

• request access to your personal data;
• request correction of inaccurate personal data;
• request deletion of personal data where applicable;
• request restriction of processing;
• object to certain processing based on legitimate interests;
• receive certain personal data in a portable format where applicable; and
• withdraw consent where processing is based on consent.

These rights are subject to the conditions and exceptions provided by applicable data-protection law.

11. Complaints

If you believe that your personal data has been processed unlawfully, you have the right to lodge a complaint with a competent data-protection supervisory authority.

In Cyprus, the relevant supervisory authority is the Office of the Commissioner for Personal Data Protection of the Republic of Cyprus.

You may also contact us first and we will try to address your concern.

12. Security

Reasonable technical and organisational measures are used to protect the website, its restricted resources and any personal data processed through it.

However, no internet-based system can guarantee absolute security.

13. Changes to This Privacy Policy

This Privacy Policy may be updated if Lyras Guitar Tools changes its functionality, introduces new services or third-party technologies, or if applicable legal requirements change.
