Terms & Conditions

1. Who we are

SixStringer ("we", "us") provides this service. When you use SixStringer you are entering into an agreement with us.

2. Acceptance

By creating an account or continuing to use SixStringer, you agree to these terms. If you do not agree, please stop using the service. You must be of legal age in your country, or have a parent or guardian's permission.

3. The service

SixStringer is an online guitar learning app with step-by-step lessons, progress tracking, and Riffmaster, an AI guitar teacher. You are responsible for keeping your login details safe and for activity under your account.

4. Acceptable use

You must not misuse SixStringer, including:

• using it for anything unlawful, fraudulent, or for spam;
• infringing anyone's intellectual property;
• interfering with security — uploading malware, probing, scraping, or attacking the service;
• reselling, redistributing, or reverse engineering the service or its content.

5. AI teacher (Riffmaster)

• Do not use Riffmaster to create illegal, hateful, or harmful content, deepfakes, or malware, and do not try to bypass its safety rules ("jailbreaking").
• You are responsible for what you send to Riffmaster and for how you use its answers. You must have the right to any content you share.
• Riffmaster's answers are generated by AI and may be inaccurate. Use your own judgement.
• Riffmaster teaches techniques and styles with original examples and does not reproduce copyrighted songs. Rights-holders can report concerns to us and we will remove infringing content; repeated infringement leads to account suspension.
• We may moderate, filter, or remove content and restrict accounts that break these rules.

6. Intellectual property

You retain rights to your input. You grant us permission to host and process it solely to provide SixStringer. AI outputs may not be unique or protectable; no rights to third-party works are granted. Rights-holders can report concerns through our contact page.

SixStringer owns all its software, lessons, branding, and documentation. We give you a limited, personal, non-transferable licence to use the lessons you have access to.

7. Payments

Payments are one-time and processed securely by our payment provider, Stripe. Prices are charged in Swedish kronor (SEK); applicable taxes are calculated at checkout. Your bank statement may show "LINK.COM*" with our name. Refunds follow our Refund Policy; see also Pricing.

Your first lesson and 5 Riffmaster questions are free. A single-lesson purchase includes only that lesson. The all-lessons purchase includes 100 additional Riffmaster questions once, not unlimited or monthly chat. Questions are counted when submitted; requests that receive no AI answer do not use a question. Full refunds and chargebacks revoke purchased access.

8. Service level

We work hard to keep SixStringer running, but we do not guarantee it will be uninterrupted or error-free. The service is provided "as is" to the fullest extent permitted by law.

9. Suspension and termination

We may suspend or end your access if you materially breach these terms, fail to pay, create a security or fraud risk, or repeatedly or seriously break our rules. You can delete your account at any time by contacting us.

10. Liability

To the extent permitted by law, we are not liable for indirect or consequential losses, and our total liability is limited to the amount you paid us in the past 12 months. Nothing limits liability for fraud, death, or personal injury where the law does not allow it.

11. Governing law

For service and privacy requests, use our contact page. Account deletion is available in your profile; required purchase records are retained for accounting.

These terms are governed by the laws of Sweden.
