Privacy Policy
Effective date: July 9, 2026
SIMMemo is an iOS app for tracking SIM and eSIM numbers, related service accounts, balances, and keep-alive reminders. This policy explains how the app handles your information.
Information You Enter
SIMMemo lets you save records such as:
- Phone number labels, country or region, dial codes, carriers, SIM card type, balances, and keep-alive dates.
- Service account names, websites, notes, linked phone numbers, and optional passwords.
- Notification and display preferences, such as whether full phone numbers are shown in the app.
Where Your Data Is Stored
By default, SIMMemo stores app data locally on your device. Passwords are stored in the iOS Keychain rather than in plain app database fields.
If you enable iCloud sync in SIMMemo settings, your phone-number and account records sync through your private iCloud account using Apple's CloudKit service. Passwords may sync through Apple's synchronizable Keychain. The developer does not operate a SIMMemo server that receives these records.
Notifications
SIMMemo can schedule local keep-alive reminders if you grant notification permission. Notification settings can be changed in iOS Settings at any time.
Clipboard
When you tap the copy button for a saved password, SIMMemo writes that password to the system clipboard so you can paste it where needed.
Data Collection and Tracking
SIMMemo does not include advertising SDKs, analytics SDKs, or third-party tracking. The developer does not sell your data and does not use your data to track you across apps or websites owned by other companies.
Third-Party Services
SIMMemo uses Apple system services including iCloud, CloudKit, Keychain, UserNotifications, and SwiftData. Your use of Apple services is also subject to Apple's privacy policy and iCloud terms.
Data Deletion
You can delete saved phone numbers and service account records inside the app. Deleting the app from your device removes local app data. If iCloud sync is enabled, iCloud data can also be managed through Apple ID and iCloud settings.
