Best Google Calendar alternative: end-to-end encrypted Calendar with Tuta.

Google Calendar might be one of the most popular and used calendars globally, but that doesn't mean it wins for privacy.

Google Calendar vs Tuta Calendar

As people become more aware of Google's endless data breaches and lack of user privacy, many are opting for privacy-focused app alternatives. A quick way to ditch Google Calendar is to get a free end-to-end encrypted calendar with Tuta!


Google’s wide range of productivity tools have become the default go-to apps for many people. But how is it possible that big tech can offer so many productivity tools for free? The sad truth is that their apps and services aren’t actually free – you pay with your privacy.

As more of Big G’s shortcomings, lack of user privacy, and scandals come to light, people are looking for better apps - more importantly, ones that respect their privacy and data. Finding a privacy-respecting service is even more important when it comes to your calendar.

Your calendar, holds the data of your daily life: all your appointments, meetings, and possibly meeting locations. So it’s understandable that you wouldn’t want Google to have first- class access to your daily routine and meetings.

Luckily, there are better alternatives to Google Calendar, the best for privacy and security being Tuta Calendar.

Keep reading as we go more into detail about some concerning issues with Google Calendar, why you might want to opt for a privacy-focused alternative instead. Finally, we fill you in on the best calendar app that’s totally free: Tuta.

The problem with Google Calendar

Google is mining your data and profiling you

If you keep up to date with Tuta News, you’ll know we’ve done some in-depth coverage on Google, its scandals, and more recently, the best practices to De-Google your life.

But more than that, you’ll be aware of Google’s lack of user privacy and invasive data mining tactics when you use their apps - including the Google Calendar.

Google knows a lot about you, and if you use the Google calendar, then they know even more! From your appointments, events, schedule, and meeting locations – Google collects it all.

Like the other data they collect from the apps you use, your calendar is also used to create a detailed profile of you for advertising purposes.

Google knows and collects it all

You might notice that Google gives very vague information as to what data they collect, exactly why they collect it and how they use it.

We took the image above from a section of Google Calendar Help answers, you’ll see that the highlighted text shows every time they mention different types of information they collect which is a lot. In another section of this Help page, they go on to say, “When you use Google Calendar, we process some data to offer you better experiences in the product.” What data, how long Google keeps it for and what Google does with it remains unknown. This is again highlighted in the image above, they outright tell you they are collecting it, but they give very little to no detail further.

When you create an appointment in Google Calendar, you might be one of those organized people who likes to add the exact location. Through this location tracking, Google is able to collect extremely accurate location data. And like they’ve mentioned in their privacy policy, they use your location to suggest nearby places when you edit events.

Google makes it quite clear that they do not use your personal content from your calendar for advertising purposes, but why then, do you sometimes see location-targeted ads?

The privacy policy also states, “We don’t use information in apps where you primarily store personal content—including Google Calendar—for advertising purposes, period.” However, if they suggest a location to you, you would think that this location they’ve chosen to suggest to you is based off some kind of paid-for promoted content.

While it might seem strange that Google can access this location data that you’ve added to your calendar appointment, it’s worth noting that if you have Google Maps and have enabled location history then the tech giant is collecting almost every step you take.

If that’s new information, you might also want to swap out Google Maps too, and luckily there are also many Google Maps alternatives that better respect your privacy and help you navigate your way.

Can you really trust Google?

Free is not free online

Google makes the majority of its revenue from advertising which is no surprise because their products and services are the perfect way for them to mine user data, sell it to third parties, and target us with advertisements – unsurprisingly Facebook is no different. That’s why big-tech like Facebook and Google are free!

Endless scandals and privacy washing

We also know Google is not innocent when it comes to their business practices and are often hit with lawsuits and fines. But a bad look is not good for revenue, so Google had to do something about the constant bad publicity.

Like other big tech companies, they’ve adopted convincing privacy-washing campaigns as part of their marketing strategy. Through using clever wording in their privacy policies and convincing campaigns, these privacy-washing tactics are the perfect way to make the user feel like they are in control of their data. But this is not the whole truth.

A perfect example of this is their Incognito Mode Scandal where Chrome users believed they were not being tracked when they browsed the web in Incognito Mode, but as it turned out Google had been tracking and collecting their data the whole time.

No end-to-end encryption

Beyond knowing that the big tech mines user data, and uses it in ways we still don’t fully know, another reason we can’t trust Google and its products like Gmail and Calendar is because **they do not use end-to-end encryption. ** With Google’s productivity tool, your data is encrypted during transmission and at rest, but not secured with end-to-end encryption. What this means in simple terms is that **Google is able to access all your calendar data ** which begs the question of privacy – your calendar isn’t truly private if Big G has open access to it.
