License and Purchase Verification

All licenses, billing processes, and purchase histories are managed entirely by Google. Our team does not have access to your personal financial records or Google Account details.

Sharing Purchases: Purchases made via Google Play can seamlessly be shared across multiple personal Android devices, provided they are logged into the exact same Google account. For aCalendar+ bought as a paid app after July 2, 2016, your purchase is eligible for the Google Play Family Library, allowing you to share the app with up to 5 family members. Unfortunately, it is not possible to activate the Family Library for earlier purchases. Please note that transferring your license from one Google account to another is completely impossible. For more information about different purchase models, please read our guide About Upgrades.

Troubleshooting Play Store Issues

If the Play Store app fails to download updates or refuses to recognize your previous premium purchase, the issue is usually caused by temporary data mismatch within the local Google Play Store service on your phone.

1

Verify Your Active Google Account

Open the Google Play Store app, tap your profile icon in the top right corner, and ensure that the account currently active matches the exact email address you used to originally buy the app or the in-app purchase.

2

Clear Google Play Services Cache

Go to your Android device Settings → Apps → select Google Play Store → choose Storage → tap Clear Cache and Clear Data. Restart your device afterwards. This forces the Play Store to safely refresh your license list directly from Google's servers.
