The free version of aCalendar is supported by advertisements to keep development going. If you prefer a clean layout without disruptions, you can easily remove them. Here is how the ad-free option works and how to distinguish app ads from calendar spam.

How to Remove Advertisements

To permanently enjoy a completely ad-free experience, you have two simple choices. Both are one-time purchases with no recurring subscriptions:

Option A: Buy the aCalendar+ Paid App

You can purchase and install the separate premium app aCalendar+ from your official app store. It has all features unlocked automatically and contains no ad libraries. For more details on this, please read our guide Google Play Store.

Option B: Get the Ad-Free In-App Purchase

If you prefer to keep using the free version you already installed, you can purchase the standalone Ad-Free upgrade inside the app's shop menu. This instantly stops the regular application from loading or showing any promotional banners.

Our Strict Advertisement Policy

We respect your privacy and user experience. Even in our free app version, we stick to a highly regulated and user-friendly setup:

✓

Strict Limits

The free version of aCalendar is carefully coded to never display more than one advertisement per single day to protect your focus and phone memory.

✓

No Hidden Ad Networks

We use verified networks (like the Facebook Audience Network) and never integrate sketchy background ad scripts that drain your battery or leak personal data.

Important: App Ads vs. Calendar Spam

Are you seeing weird, suspicious ads directly inside your calendar grid list (such as "Your phone is infected" or "Win a prize" event entries)?

This is not coming from aCalendar! Even if you purchase an ad-free license, these spam calendar entries will not disappear. They are rogue events injected directly into your cloud service database (like your Google or Microsoft account) by third-party websites. To learn how to safely clean your calendar database from these unwanted entries, please see our dedicated guide on Spam in your calendar.
