Privacy Policy

Old Privacy Policy

Your privacy is critically important to us.  At Trala we have a few fundamental principles:

  • We don’t ask you for personal information unless we truly need it. (We can’t stand services that ask you for things like your gender or income level for no apparent reason.)

  • We don’t share your personal information with anyone except to comply with the law, develop our products, or protect our rights.

  • We don’t store personal information on our servers unless required for the on-going operation of one of our services.

If you have questions about deleting or correcting your personal data please contact us at or

Trala Inc. (“Trala”) operates Android and iOS applications that help you to practice your violin more effectively. It is Trala's policy to respect your privacy regarding any information we may collect while operating our applications.

Application Users

Like most applications developers, Trala collects non-personally-identifying information of the sort that Android and iOS devices typically make available, such as the device type, OS version, language preference, and the date, time, and type of each user request. Trala's purpose in collecting non-personally identifying information is to better understand how Trala's users use its applications. From time to time, Trala may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in the usage of its application.

Trala also collects potentially personally-identifying information like Internet Protocol (IP) addresses for logged in users. Trala only discloses logged in user IP addresses under the same circumstances that it uses and discloses personally-identifying information as described below.

Gathering of Personally-Identifying Information

Users of Trala are asked for their email, name and teacher's email.  These are used only to provide the services that constitute the Trala application.  For example, the student's practicing record is sent to teachers.  These details are used only for this purpose and are never disclosed in any other case.  In any case, Trala collects such information only insofar as is necessary or appropriate to fulfill the purpose of the user's interaction with Trala.  Trala does not disclose personally-identifying information other than as described below. 

Aggregated Statistics

Trala may collect non-personally-identifying statistics about the behavior of visitors to its websites and applications. Trala may display this information publicly or provide it to others. However, Trala does not disclose personally-identifying information other than as described below.

Protection of Certain Personally-Identifying Information

Trala discloses potentially personally-identifying and personally-identifying information only to those of its employees, contractors and affiliated organizations that (i) need to know that information in order to process it on Trala's behalf or to provide the services offered in Trala’s applications, and (ii) that have agreed not to disclose it to others. Some of those employees, contractors and affiliated organizations may be located outside of your home country; by using Trala websites, you consent to the transfer of such information to them. Trala will not rent or sell potentially personally-identifying and personally-identifying information to anyone. Other than to its employees, contractors and affiliated organizations, as described above, Trala discloses potentially personally-identifying and personally-identifying information only in response to a subpoena, court order or other governmental request, or when Trala believes in good faith that disclosure is reasonably necessary to protect the property or rights of Trala, third parties or the public at large. If you are a registered user of Trala and have supplied your email address, Trala may occasionally send you an email to tell you about new features, solicit your feedback, or just keep you up to date with what’s going on with Trala and our product. We expect to keep this type of email to a minimum. If you send us a request (for example via a support email or via one of our feedback mechanisms), we reserve the right to publish it in order to help us clarify or respond to your request or to help us support other users. Trala takes all measures reasonably necessary to protect against the unauthorized access, use, alteration or destruction of potentially personally-identifying and personally-identifying information.

Business Transfers

If Trala, or substantially all of its assets, were acquired, or in the unlikely event that Trala goes out of business or enters bankruptcy, user information would be one of the assets that is transferred or acquired by a third party. You acknowledge that such transfers may occur, and that any acquirer of Trala may continue to use your personal information as set forth in this policy.


Trala does not show advertisements in any of its applications.  There never has been and never will be anything in our applications that does not directly help you or your student better practice violin.  This, we promise.

Privacy Policy Changes

Although most changes are likely to be minor, Trala may change its Privacy Policy from time to time, and in Trala's sole discretion. Trala encourages users to frequently check this page for any changes to its Privacy Policy. If you have a Trala account, you may get an email notification when something significant in this respect happens.


Many thanks to for having such sensible values when it comes to privacy and creating a free and easily adaptable policy.
