ieKarte Support
ieKarte helps you manage your home's maintenance schedule, appliance warranty expirations, and repair history — all in one place. "When did I last clean the AC filter?" "Is this still under warranty?" ieKarte answers those everyday questions about your home.
Frequently Asked Questions (FAQ)
I'm not receiving maintenance reminder notifications. What should I do?
Please make sure notifications are enabled in iOS Settings > Notifications > ieKarte. Also confirm that the "Maintenance Reminders" toggle is on under the Settings tab inside the app. If you declined the notification permission during onboarding, you'll need to enable it from iOS Settings.
Where is my data stored? Is it uploaded to the cloud?
All data you enter (property info, appliances, repair history, etc.) is stored only on your device. It is never sent to our servers. When we ship the family sharing feature in a future update, data will be shared via Apple's iCloud (CloudKit) only.
What's the difference between the Free and Premium plans?
Core features (maintenance reminders, appliance warranty tracking, repair history) are fully available on the Free plan. With Premium (¥300/month or ¥2,800/year), ads are removed. Future updates will add Premium-exclusive features such as multi-property support, family sharing, and detailed reports.
How do I cancel my Premium subscription?
Go to iOS Settings > your Apple ID > Subscriptions, and cancel ieKarte Premium from there. Cancellation cannot be done inside the app, but you can cancel at any time from the standard iOS screen.
Can I migrate my data to a new device?
In the current version (v1.0.0), data is stored locally, so please use iCloud Backup when switching devices. Future updates will add manual export (CSV/PDF) and automatic sync via CloudKit.
I purchased Premium but it hasn't been applied.
Please tap "Restore Purchases" at the bottom of the Settings > "Upgrade to Premium" screen in the app. Also verify that you are signed in with the same Apple ID used for the purchase. If it still doesn't apply, please contact us at the email address below.
Which iOS versions are supported?
ieKarte supports iPhone running iOS 17 or later. iPad is not currently supported.
