Frequently Asked Questions
Do I need a credit card to start the trial?
No. Callro's 7-day free trial requires absolutely no payment information upfront. Just download the app, activate the 26-layer Gauntlet Engine, and see the results for yourself.
What happens after the 7-day trial?
After 7 days, you can choose to subscribe for $9.99/month to keep the active call screening features enabled. If you do not subscribe, the premium features will simply pause. You will not be automatically charged because we never collected your card.
Are there any hidden fees or upsells?
No. The $9.99/month subscription unlocks 100% of Callro's features. We do not sell your data, we do not show ads, and we do not have a tiered premium structure. One price, complete protection.
How do I cancel my subscription?
You can cancel anytime directly through the Google Play Store subscription manager with a single tap. There are no cancellation fees and no phone calls required.
Why isn't Callro free like some other blockers?
Free call blockers monetize your data by uploading your contact list and selling call metadata to advertisers. Callro charges a transparent monthly fee so we can keep your data on your device without uploading your contacts or call audio.
