Regarding the newsletter and agreements

The following text informs you about the content of our newsletter. It further specifies the process of logging in, sending mails and provides information about data analysis and your rights to cancel the newsletter. In subscribing to our newsletter you agree to all those processes.

We exclusively send newsletter, emails and further electronic notifications with promotional information (following called „newsletter“) with consent of the receiver or a legal permission. As long as the newsletters content is correctly paraphrased in the process of subscribing to it those contents are relevant for the users approval. We will inform you about software products made by us especially our TeacherStudio Teacher App.

Doule-Opt-In and logging

The subscription to our newsletter uses a so called Double-Opt-In-Procedure. This means you’ll receive an email after initially subscribing to the newsletter which will ask you for a second approval. This approval is necessary to prevent people to subscribe email addresses which they don’t own.

The newsletter subscribtions are logged to verify the legally correctness of the subscription process. The logged information contains the time of the subcription and confirmation as well as the used IP address. Further changes of your data saved by MailChimp are logged.

Statistical evaluation and analysis

The newsletters contain a so called „web-beacon“. This is a pixel sized file which is fetched from MailChimps servers when a newsletter is opened. This happens to collect technical information of the used browser and system as well as the IP address and the time of the opening. This information is used to technically improve the service by analyzing the technical data, target audience and reading behavior specific to the country of origin ( this can be determined by the IP address ) and time of opening.

Additionally it is determined statistically if and when the newsletter has been opened and which links have been clicked. This information can for technical reasons be assigned to the newsletters receivers. It is neither ours nor MailChimps aspiration to monitor invidual users. This statistics are used to understand our users reading habits to better tailor out content for their interests.

Personal information

All entered data if personal or not is saved locally on the device and never transmitted without explicit permission.

TeacherStudio does not collect data automatically. The data has to be entered manually or by using the import functions like the import of students via CSV files. Data can be overwritten by restoring an TeacherStudio backup file.

The user decides which data is entered in TeacherStudio. All data can be entered anonymous if so desired. All data is saved for the duration of its usage. The user can delete the data at any time.

Local security features

Personal data (name, birthday, contact information, remarks, pictures) can be locally encrypted when the user activates the local encryption in the apps options. The local encryption is optional because it can affect performance and many devices are already encrypted nowadays.

Further the user can limit access to the app by setting a password which is checked on every app startup.

Technical information

The data is saved in a storage space provided by the used operating system. This data and the provided storage path can change with a operating system update. To ensure that a newer app version can import data for backup purposes all backups should be created in TeacherStudio by the functions provided.

On Windows TeacherStudio can (like every Store App) access a subfolder with the name „TeacherStudio“ in the users Downloads folder. TeacherStudio saves encrypted backups to this folder automatically if a password for backups is set in the apps settings.

Limited, non-identifiabel technical information (such as OS version, language settings, crash information) is sent to HockeyApp in the form of crash reports to detect and correct technical problems.

Exporting data

TeacherStudio provides a function to export most of its saved data to a Microsoft Excel file. That way data can be exported and printed. Further TeacherStudio can create encrypted backup file to enable the user to restore this data. Further TeacherStudio can synchronize data between multiple devices by using a cloud provider (ff).

Usage of cloud providers

TeacherStudio can synchronize data with online storage provided by cloud services like Microsoft OneDrive and Google Drive. The requires the user to authorize with her/his username and password, which are not stored or read by TeacherStudio. TeacherStudio only stores a so called access token which the cloud service provides and allows logins without entering username and password again for a specific time. This token is stored encrypted and deleted when the user logs out of the cloud service in TeacherStudio. The token is refreshed from time to time. If it should expire the user has to authorize again.

The synchronized data itself is always encrypted and only transferred encrypted via SSL. The encryption requires a password chosen by the user which is used for encryption and decryption. Neither the cloud service provider nor we or the user can decrypt this data without knowing the password.

Sending of mails

TeacherStudio can prepare mails on demand. These mails are not sent by TeacherStudio. TeacherStudio only tells the operating systems, that a mail should be sent and which contents it should contain. This starts the mail app which is configured for sending mails on the used device.

Usage of Microsoft OneNote

TeacherStudio can link the planning of lessons to OneNote pages on demand. This requires a login with a Microsoft account TeacherStudio can then read OneNote notebooks available on Microsoft OneDrive or Microsoft Offices 365. Unique identification numbers of the OneNote pages are saved in the TeacherStudio 3database. A preview of the pages using the formats Html and Inkml is saved in the storage space of TeacherStudio. This data is not synchronized.


TeacherStudio requires some permissions to perform its functions. Dependent on the used operating system these permissions have to be granted when installing the app or during the usage.

  • Read and write access to the storage space provided by the operating system for TeacherStudio
  • Read access to the pictures folder to choose student pictures
  • Access to the camera to capture student pictures
  • Access to the interface for handling in app purchases to purchase the app
  • Internet access to send error reports and use the cloud synchronization


The used encryption is state of the art. The data is encrypted with AES with a key length of 256bit. The key is generated by using PBKDF2. The key is „salted“ to render so called „rainbow tables“ useless. At this time there are no successful attacks on AES known.

Third Party

TeacherStudio makes (optional) use of third party services, whose usage of information is excluded from this privacy policy. The usage of a third party service is always voluntary and clearly stated. Any data shared with those services is when technically viable encrypted before being sent or stored outside of TeacherStudio.


All information refers to the most current app version and is compiled to the best of our knowledge. Changes can be necessary due to improvements and changes of the app. We are not responsible for improper use of function (e.g. entering personal data in fields which are not designated for it).
