Frequently Asked Questions (FAQ)

Q. Do I need to create an account to use the app?

No. Registration or account creation is completely unnecessary. You can start using the app immediately after downloading.

Q. Where is my data stored and synced?

All your created cards and settings are stored locally on your device. For multi-device synchronization, your data syncs securely via Apple's native iCloud infrastructure (CloudKit / Key-Value Store) tied directly to your personal Apple ID. Your data is never transmitted to or stored on any external third-party servers.

Q. What should I do if sync isn't working between my iPhone and Mac?

Please verify the following:

  1. Both devices are signed in with the same Apple ID (iCloud account).
  2. iCloud Drive and Stack sync are enabled under Settings > [Your Apple ID] > iCloud.
  3. An active internet connection is available on both devices.

Q. Are there any fees, ads, or in-app purchases?

Stack is 100% free to use. There are no advertisements, in-app purchases, or subscription fees.
