To deliver and support the features of Melo-D Guitar, we may request access to certain device permissions. All permissions are requested only when necessary and only upon your active use of related features. We do not request or access permissions in the background without your knowledge and consent. You may enable or disable these permissions at any time through your device settings. Disabling a permission will only affect the corresponding feature and will not impact other services of the app.
We request Bluetooth permission to connect with musical instruments. This permission is used to pair with instruments, adjust preset parameters, and transmit sheet music information when you turn on Bluetooth and attempt to connect to a device. We will prompt for your consent only when you actively tap to connect or search for a device. You may disable this permission at any time.
Bluetooth permission is used only for discovering, pairing, connecting, and controlling supported guitar devices. We do not use Bluetooth permission to identify, track, or infer your physical location.

The retention periods are different depending on different criteria, such as the type of information and the purposes for which we use the information. For example, when we process your information such as your account information to provide you with the Platform, we keep this information for as long as you have an account. If you violate our Terms of Service, Community Guidelines, or other conditions or policies, we may remove your account from the Platform or User Content from public view immediately, but may keep other information about you to process the violation.

Where we rely on your consent to process your Personal Information, you may withdraw your consent at any time by sending us a notice specifying which consent you wish to withdraw.

If you are a resident of California, the CCPA/CPRA requires us to provide you with the following additional notice. For the purposes of this notice, "Personal Information" means information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked, directly or indirectly, with a particular consumer or household, or as otherwise defined in the California Consumer Privacy Act of 2018 (California Civil Code Sections 1798.100 through 1798.199) and its implementing regulations, in each case as amended or replaced from time to time (the "CCPA").
The categories of Personal Information that we collect, use and disclose, and that we have collected, used and disclosed in the preceding twelve (12) months, are described in the "The Types of Information We Collect" section above.
Under California's "Shine the Light" law, California residents may request that we provide a list of third parties to whom we have disclosed certain personal data for their direct marketing purposes. You may submit such a request once per calendar year. Please include in your request sufficient information to verify that you are a California resident and provide your current California mailing address so that we can respond. You may request this information by contacting us using the contact details set out in the "Contact Us" section below. We will respond to your request within thirty (30) days. We are not able to respond to requests submitted through means other than the designated email address.
We will respond to your verifiable consumer request free of charge within forty-five (45) days by providing the requested information, correcting any inaccurate personal information, or deleting your personal information, as applicable. Where reasonably necessary, if we are unable to process your request within forty-five (45) days, we will notify you in writing of the extension within that period, and the extension will not exceed an additional forty-five (45) days.
If you are a California resident and the processing of your personal information is subject to the California Consumer Privacy Act (CCPA) and its amending statute, the California Privacy Rights Act (CPRA), you have certain rights with respect to that information:
a. Right to Receive Notice at Collection.
At or before the time we collect your information, you have the right to receive notice of our practices, including the categories of personal information and sensitive personal information to be collected, the purposes for which such information will be collected or used, whether such information will be "sold" or "shared", and the length of time we intend to retain such information. You can find these details in this section of, and the sections referenced above in, this Privacy Policy.
b. Right to Know / Access.
You have the right to request a copy of the personal information that we have collected about you during the preceding twelve (12) months.

e. Right to Opt Out / "Do Not Sell or Share My Personal Information".
You have the right to opt out of any future "sale" or "sharing" of your personal information, as those terms are defined under the CCPA and CPRA.
Please note that the CCPA defines "sell", "share" and "personal information" very broadly, and as a result, some of the data disclosures described in this Privacy Policy could be considered a "sale" or "sharing" under those definitions. However, we do not "sell" or "share" your personal information as those terms are defined under the CCPA/CPRA. We only share information with third-party service providers that provide services to us, such as hosting, analytics and customer support. These third parties are contractually restricted to using the information solely on our behalf, in accordance with our instructions, and not for their own purposes. If, in the future, we were to engage in any "sale" or "sharing" of personal information, we would update this Privacy Policy and provide you with an appropriate Opt-Out mechanism.
f. Right to Limit the Use of Sensitive Personal Information.
For data that is classified as "Sensitive Personal Information" under the CPRA, you have the right to request that we limit its use to: providing you with the services or goods that you can reasonably expect, and other specific circumstances permitted by law.
At present, we do not use sensitive personal information for any purposes beyond those described above.
g. Authorized Agent.
You may designate an authorized agent, in writing or through a valid power of attorney, to submit requests to access, correct or delete your personal information on your behalf. We will require the authorized agent to provide proof of authorization before accepting the request, and we may also require you to complete identity verification directly with us.
h. Verification Requirements.
In order to fulfill your requests described above, we are required by law to verify your identity. We typically do so by asking you to submit your request using the email address associated with your account, or by asking you to provide information that matches the information associated with your account.
i. Right to Non-Discrimination.
We will not discriminate against you for exercising any of your rights under the CCPA. This includes not denying you services, not charging you different prices or rates, and not providing you with a different level or quality of services, except where differential treatment is permitted by law (for example, lawful differential pricing).
j. Direct Marketing Disclosures.
We will not disclose your personal information to any third parties for their own direct marketing purposes, as defined under California law.
For users located in the Commonwealth of Virginia, we comply with the Virginia Consumer Data Protection Act (VCDPA). You may exercise the following rights under the VCDPA:
You may submit a request to exercise your VCDPA rights by contacting our Data Protection Officer using the contact information listed above. We will not discriminate against you for exercising your privacy rights under applicable law.
If you are located in the European Economic Area (EEA), the United Kingdom, or Switzerland, you may have additional rights under applicable data protection laws.
To exercise any of the rights described above, you may contact us via our webform. Before responding to your request, we may require you to verify your identity or provide additional information to ensure that we can properly understand and process your request.

You also have the right to lodge a complaint with the Irish Data Protection Commission (as our lead supervisory authority) or with the supervisory authority in your country of residence, place of work, or place of the alleged infringement.
Where we transfer your personal data outside of the EEA, the UK, or Switzerland, we ensure that such transfers are subject to appropriate safeguards in accordance with applicable data protection laws, including, where applicable, the use of standard contractual clauses or other legally recognized transfer mechanisms to ensure an adequate level of protection.

You have rights and choices when it comes to your information. You may be afforded certain rights under applicable laws, which may include the right to access, delete, update, or rectify your data, to be informed of the processing of your data, to file complaints with authorities, and potentially other rights.

The security of your information
We take steps to ensure that your information is treated securely and in accordance with this policy. Unfortunately, the transmission of information via the internet is not completely secure. Although we will use reasonable measures to protect your personal data, for example, by encryption, we cannot guarantee the security of your information transmitted via the Platform; any transmission is at your own risk.
We have appropriate technical and organizational measures to ensure a level of security appropriate to the risk of varying likelihood and severity for the rights and freedoms of you and other users. We maintain these technical and organizational measures and will amend them from time to time to improve the overall security of our systems.
Our service is not directed to individuals under 13 years old. We do not knowingly collect personal information from anyone under 13. If we become aware that a person under 13 has provided personal information to us, we will delete such information and terminate the account. If you believe we have collected information from a minor under 13, please contact us at info@tempolorguitar.com.
In order to continuously improve our Services, we may need to amend this Privacy Policy from time to time. If we make any such changes, we will generally notify all users of any material changes to this Policy, by posting an announcement on the Melo-D Guitar Platform, by sending you an email and/or by using other means. However, you should look at this Policy regularly to check for any changes. We will also update the "Last Updated" date at the top of this Policy, which reflects the effective date of the Policy.
