Are you concerned about privacy leaks via a calendar app? Or trying to figure out how to protect your calendar? 

A secure calendar app makes this possible with password protections, encryptions, and permission management.

In this article, you will discover why calendars need security features and how to secure them, two prominent security features you should look for when investing in a calendar app, and a list of most secure calendars you can install and try out this year.

Why is Security Important for Calendars and Online Scheduling?

Calendars are designed for synchronizing data from different devices, auto upgradation of tasks and events, and scheduling your upcoming plans. These activities require sharing your data with the calendar you’re using.

Thus it’s essential to have an end-to-end encrypted calendar that prohibits third parties and the app itself from acquiring your personal information. 

When choosing the best digital calendar, privacy must first be considered apart from all the productivity-boosting features. 

It has been found that big data companies use the information fed by the users in the calendar for targeting ads. 

They try to know about their life goals and preferences by sneaking around the given data. This is why calendar security is becoming important day by day. 

But how do you secure your calendar? Let’s see!

How to Secure Your Calendars?

First and foremost, use secure online calendars for personal and business purposes. 

Enabling password-protected calendars links can also help secure your information while sharing.

A timely review of your calendar lets you know with whom you share your data. 

Being aware of the permission levels at the beginning might help in choosing the right calendar for your organization. 

Security Features Your Calendar Should Ideally Have

#1. Permission Management

If you use a calendar to bring your team on board and share it with them, permission management features can come in handy.

Sometimes, depending on your business, you might need some specific teammates to look at team meetings with particular clients. 

The calendar app you choose for your business should have the feature to assign specific client meetings to certain team members.

#2. 2-Factor Authentication

2-factor authentication is a protection layer you set above the normal password protection.

How it works is that whenever you log into your account via username and password, you either get an email on the registered mail id or an OTP on your submitted mobile number.

This helps you prevent getting hacked big time.

Now that you know about calendar security, let’s look at some secure calendars you can use.
