Partners working for MUSOPIA

MUSOPIA has partners to perform services for us. These partners process your data only at and according to MUSOPIA´s instructions to provide the Service, such as hosting, user support, advertising, analytics and fraud prevention.

Other companies and public authorities

In order to combat fraud and illegal activity, we may exchange data with other companies and organizations and provide it to public authorities in response to lawful requests.

We may also disclose your data based on your consent, to comply with the law or to protect the rights, property or safety of us, our users or others.

Our Service is global by nature and your data can therefore be transferred to anywhere in the world.

Cookies and similar technologies

Like most online services, we and our partners use cookies and similar technologies to provide and personalize the Service, analyse use, and prevent fraud. You can disable cookies in your browser settings, but some parts of the Service may then not function properly.

Description of cookies

When signing up for JustinGuitar app with sign up, we don’t by default set cookies or track you without your consent.

If you don’t consent to cookies, we only set the following strictly necessary cookies:

  • cookie_consent: allows the site to remember your choice of whether you allow cookie
  • visits: stores the query parameters of your url when you landed to our site, to enable custom pricing to be automatically applied to your when you sign up. The query parameters pass this data to the pricing functionality of the site, and are thus necessary for the flow to function.

  • _ga: google analytics tracking identifier, used for tracking website activity for site improvement and marketing measurement
  • ga***: google session identifier, used for tracking website activity for site improvement and marketing measurement
  • (Possibly the cookies set by the signup or authentication option you choose - for example gmail account signup and authentication - to enable your sign up and authentication to your justinguitar app account)
  • (Possibly the cookies set by our payment Provider Stripe to enable secure handling of your payment)

How do we protect your data

Security Safeguards

In order to help ensure a secure and safe user experience, we are continuously developing and implementing administrative, technical and physical security measures to protect your data from unauthorized access or against loss, misuse or alteration.

For technical measures to protect your data in-transit, we utilise industry standard TLS encryption for your communication with our services.

In order to minimise the identifiable data we collect about you, we only use your account identifiers, for example your email address to enable your account sign up and login.

In order to process your payments for your paid subscription, we defer the handling of your account transactions and payments to third parties (Stripe and Revenuecat, depending on your payment method) that are using industry standard and compliant security measures for handling your payment information, such as credit or debit card details. We don’t process or store information related to your payment method.

Data retention

We retain your data for as long as your account is active or as needed to provide you the Service. We will for example periodically de-identify unused service accounts and we regularly review and de-identify unnecessary data. When you wish to stop using your account, you may delete your account, which results in us anonymising your account details.

Note that if you ask us to remove your personal data, we will retain your data as necessary for our legitimate business interests, such as to comply with our legal obligations, resolve disputes, and enforce our agreements. For example accounting regulations and dispute use require us to keep records of customer payment transactions up to 10 years.

Opt out of digital advertising and marketing messages

You can opt-out of interest-based advertising on mobile applications by checking the privacy settings of your Android or iOS device and turning off “Allow Apps to Request to Track” or selecting “Limit Ad Tracking” (Apple iOS) or “Opt-out of Interest Based Ads” (Android).

You may opt out of receiving promotional communications, such as marketing emails from us by following the instructions in such communications, or by changing your in-app settings. The updated settings may not be effective immediately.

We do not knowingly collect or solicit personal data about or direct or target interest based advertising to anyone under the age of 13 or knowingly allow such persons to use our Services. If you are under 13, please do not send any data about yourself to us, including your name, address, telephone number, or email address. No one under the age of 13 may provide any personal data.

If we learn that we have collected personal data about a child under age 13, we will delete that data as quickly as possible. If you believe that we might have any data from or about a child under the age of 13, please contact us.
