Privacy Policy

Last updated: May 01, 2023

This policy explains what information we collect when you use selfplayingpiano (“OPA”) sites, services, mobile applications, products, and content (“Services”). It also has information about how we store, use, transfer, and delete that information. Our aim is not just to comply with privacy law. It’s to earn your trust.

Information We Collect & How We Use It

In order to give you the best possible experience using OPA, we collect information from your interactions with our network. Some of this information, you actively tell us (such as your email address, which we use to track your account or communicate with you). Other information, we collect based on actions you take while using OPA, such as what pages you access and your interactions with our product features. This information includes records of those interactions, your Internet Protocol address, information about your device (such as device or browser type), and referral information.

We use this information to:

• provide, test, improve, promote and personalize OPA Services

• fight spam and other forms of abuse

• generate aggregate, non-identifying information about how people use OPA Services


Information Disclosure

OPA won’t transfer information about you to third parties for the purpose of providing or facilitating third-party advertising to you. We won’t sell information about you.

We may share your account information with third parties in some circumstances, including: (1) with your consent; (2) to a service provider or partner who meets our data protection standards; (3) with academic or non-profit researchers, with aggregation, anonymization, or pseudonomization; (4) when we have a good faith belief it is required by law, such as pursuant to a subpoena or other legal process; (5) when we have a good faith belief that doing so will help prevent imminent harm to someone.

If we are going to share your information in response to legal process, we’ll give you notice so you can challenge it (for example by seeking court intervention), unless we’re prohibited by law or believe doing so may endanger others. We will object to requests for information about users of our services that we believe are improper.

Data Storage

OPA uses third-party vendors and hosting partners, such as Hetzner, for hardware, software, networking, storage, and related technology we need to run OPA. We maintain two types of logs: server logs and event logs. By using OPA Services, you authorize OPA to transfer, store, and use your information in the countries where we operate.

Third-Party Embeds

Some of the content that you see displayed on OPA is not hosted by OPA. These “embeds” are hosted by a third-party and embedded in OPA. For example: YouTube or Vimeo videos, Facebook, Google Analytics, ClickMagic, Twitter tweets, Apple store and Google Play store. These files send data to the hosted site just as if you were visiting that site directly (for example, when you load a OPA post page with a YouTube video embedded in it, YouTube receives data about your activity). OPA does not control what data third parties collect in cases like this, or what they will do with it. So, third-party embeds on OPA are not covered by this privacy policy. They are covered by the privacy policy of the third-party service.

Some embeds may ask you for personal information, such as your email address, through a form. We do our best to keep bad actors off of OPA. However, if you choose to submit your information to a third party this way, we don’t know what they may do with it. As explained above, their actions are not covered by this Privacy Policy. So, please be careful when you see embedded forms on OPA asking for your email address or any other personal information. Make sure you understand who you are submitting your information to and what they say they plan to do with it. We suggest that you do not submit personal information to any third-party through an embedded form.

If you embed a form that allows submission of personal information by users, you must provide near the embedded form a prominent link to an applicable Privacy Policy that clearly states how to you intend to use any information collected. Failure to do so may lead OPA to disable the post or take other action to limit or disable your account.

Tracking & Cookies


We use browser cookies and similar technologies to recognize you when you return to our Services. We use them in various ways, for example to log you in, remember your preferences (such as default language), evaluate email effectiveness, personalize content and other information.

OPA doesn’t track you across the Internet. We track only your interactions within the OPA network (which encompasses and custom domains hosted by OPA).

Some third-party services that we use to provide the OPA Service, such as Google Analytics, may place their own cookies in your browser. This Privacy Policy covers use of cookies by OPA only and not the use of cookies by third parties.

OPA complies with the “Do Not Track” (“DNT”) standard recommended by the World Wide Web Consortium. For logged-out users browsing with DNT enabled, OPA’s analytics will not receive data about you, but we will do some first-party tracking in order to customize content and provide data to third-party service providers that enable OPA Services to work. When you use OPA while logged-in to your account, we cannot comply with DNT. Here’s some more information about OPA’s Do Not Track policy.




How often will you update this Cookie Statement?

We may update this Cookie Statement from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal or regulatory reasons. Please therefore re-visit this Cookie Statement regularly to stay informed about our use of cookies and related technologies.

The date of this Privacy Policy indicates when it was last updated.

How can I control cookies?

You have the right to decide whether to accept or reject cookies.

You can set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our Websites though your access to some functionality and areas of our Websites may be restricted. As the means by which you can refuse cookies through your web browser controls vary from browser-to-browser, you should visit your browser’s help menu for more information.

Disabling Most Interest Based Advertising: Most advertising networks offer you a way to opt out of Interest Based Advertising. If you would like to find out more information, please visit or

Mobile Analytics: You can opt out of having your mobile advertising identifiers used for certain types of Interest Based Advertising, including those performed by us, by accessing the settings in your Apple or Android mobile device and following the most recent published instructions. If you opt out, we will remove all data about you and no further data collection or tracking will occur. The random ID we (or our third party partners) had previously assigned to you will also be removed. This means that if at a later stage, you decide to opt-in, we will not be able to continue and track you using the same ID as before, and you will for all practical purposes be a new user to our system.

Do Not Track: Some Internet browsers - like Internet Explorer, Firefox, and Safari - include the ability to transmit “Do Not Track” or “DNT” signals. Since uniform standards for “DNT” signals have not been adopted, our Websites do not currently process or respond to “DNT” signals. MailChimp takes privacy and meaningful choice seriously and will make efforts to continue to monitor developments around DNT browser technology and the implementation of a standard. To learn more about “DNT”, please visit All About Do Not Track.

But, if you delete your account, your information and content will be unrecoverable after that time. OPA may preserve and maintain copies of your information when required to do so by law.

Data Security

We use encryption to protect data transmitted to and from our site. However, no data transmission over the Internet is 100% secure, so we can’t guarantee security. You use the Service at your own risk, and you’re responsible for taking reasonable measures to secure your account.

Email from OPA

Sometimes we’ll send you emails about your account, service changes or new policies. You can’t opt out of this type of “transactional” email (unless you delete your account). But, you can opt out of non-administrative emails such as digests, newsletters, and activity notifications through your account’s Settings page.

When your interact with an email sent from OPA (such as opening an email or clicking on a particular link in an email), we may receive information about that interaction. We won’t email you to ask for your password or other account information. If you receive such an email, please send it to us so we can investigate.

Changes to this Policy

OPA may periodically update this Policy. We’ll notify you about significant changes to it. The most current version of the policy will always available on the site and we will archive former versions of the policy as well.

OPA also pursues its legitimate interests by collecting minimal data of logged out users to provide the services, as outlined above.

In such cases, users authoring such content containing personal data of third parties are responsible for that content. OPA will consider related complaints in compliance with the General Data Protection Regulation’s rights of the data subject, as well as rights of expression and access to information.

Public Nature of Personal Data

Logged-in users may choose to interact publicly with the OPA Services in the form of clapping for a post, highlighting parts of a post, following other user accounts, sharing links on connected social media accounts, or writing original posts. Where such personal data may reveal special category protected data, it is processed on the basis that it is manifestly made public by the user.
