Klender does not use your data for commercial purposes in any way!

​

Nearly all other calendar apps claim to protect your privacy but then go on to sell your data.

​

Klender's Privacy Promises at a Glance

​

Klender does not sell your data to any third party.​

​

• No Personal Profiles: Klender does not use your data, entered information, granted access, or app usage behaviour to create personal profiles.

• No Tracking Cookies: Klender does not use tracking cookies.

• Data Use: Your data is only collected for the app's functionality or to improve its performance.

• Data Storage: Information you input or import is stored to ensure you and other members of your shared calendar can access it from any device. Deleted data is retained for six months, allowing you to recover it if needed. You can always view and permanently delete this data yourself.

• Account Deletion: When you delete your account, your data is permanently removed immediately.

While personalised ads might seem convenient, this sensitive information can also be sold to banks, insurers, governments, or even criminals. Klender strongly opposes such practices!

5. What data does Klender collect and why?

​

Account

To use Klender, you need to create an account. When creating an account, you provide your email address, first and last name, and can optionally add other calendar members.

​​

Appointments, lists, todos, messages and contacts

In Klender, you can schedule appointments, create lists with to-dos or other lists and manage contacts. All this data is by default shared in the calendar where it is created.

​

If people from outside the calendar are added to an appointment or list, they can also view this appointment or list.

​

Appointments from other calendars

You can import or display appointments from other calendars in Klender. These appointments are shared in the calendar where they are imported. Klender does not use the data from these external calendars in any other way.

​

Importing contacts

You can import contacts into Klender from your device, Google Calendar, or Outlook. These contacts are shared in the calendar where they are imported. Klender does not use contact data in any other way.

 

​Deleted data

Data you delete in Klender is retained for six months, so you can recover it if needed. You can do this yourself. You can also view your deleted data and permanently delete it if desired.

 

After six months, deleted data is automatically and permanently removed. For lists where you want to quickly restore previously deleted tasks or items, you can disable the automatic permanent deletion.

​

When you delete your account, your data is immediately and permanently deleted.

​

Automatically generated information

To ensure Klender works properly, such as displaying and securing the website or application effectively, Klender requires certain information. It collects automatically generated data about the use of Klender, including your IP address (the unique number that allows your device to be recognised), your device and its operating system, the type of browser you are using, and the pages you visit in the app. This data is used solely to detect software errors and to process anonymous statistics, which help improve the quality of the software.

​

6. What are cookies and how does Klender use them?

 

Cookies are small pieces of information that a server sends to an application or browser, intending for the application or browser to send the information back to the server during a subsequent visit. Klender cookies cannot damage your computer or the files stored on it.

​

Cookies used by Klender

Klender places technical cookies that are essential for providing the service. These cookies are necessary to remember that you are logged in and to keep track of your information during your session. This prevents the need to communicate with the server with every click, making Klender faster to use.

​

After logging out, these cookies are deleted. If you remain logged in, the information stays on your computer, phone, or tablet, ensuring that when you return, data doesn’t need to be reloaded from the server. This allows you to access your information more quickly during your next visit.

​

Klender does not use tracking cookies (cookies that track your past usage and link it to your activity on other apps and websites).

​

Third-Party Cookies

To collect anonymous statistics about the use of Klender, Klender uses Google Analytics. Google uses cookies for this purpose. However, we have not granted Google permission to use this data for its own purposes. Klender uses these statistics solely to improve the quality of the app.

​

7. How does Klender protect your data?

 

Klender takes appropriate technical and organisational measures to secure the data in Klender against loss or any form of unlawful processing.

Therefore, avoid storing highly sensitive or valuable data in online systems, including Klender.
