Frequently asked questions
Is the app free?
Yes. All features are free, with no subscription.
Why are owner details hidden for some domains?
Many registrars hide personal details for privacy. The app shows what the WHOIS record contains.
How do expiry reminders work?
Add the domain to your lists, turn on reminders and choose the intervals. Notifications are scheduled on your iPhone.
Can I back up my domain lists?
There is no backup or iCloud sync. Your lists move with an iPhone backup or device transfer.
Is a domain available to register?
If no WHOIS record is found, the domain is likely available. Confirm with a registrar before you buy.
How do I contact support?
Email [email protected], or use the contact option in the app's Settings. We usually reply within a few working days.
