Frequently asked
Questions people actually ask.
Yes. Cardper is local first. Everything you enter stays on your device unless you turn on Cloud Sync, which is off by default. We never ask for full card numbers, CVV codes or online banking credentials, and the app does not connect to your bank.
No. You can open the app and add a card straight away. An Apple or Google sign in is only needed if you want Cloud Sync across devices.
Yes. The free tier covers one personal card in one wallet, with in app due reminders, and it stays free with no time limit. Free is supported by ads.
Unlimited cards, multiple wallets including business ones, push reminders with quiet hours, all currencies, the snowball and avalanche payoff planner, cloud sync and an ad free app.
Turn it on in Settings and sign in with Apple or Google. Your records are encrypted in transit and stored on secured infrastructure, then restored on any device where you sign in with the same account. Turn it off and uploads stop immediately.
Yes, with Pro and Cloud Sync enabled. Sign in with the same Apple or Google account on each device and your cards, wallets and payment history follow you.
Cardper schedules local notifications ahead of each due date, plus one on the day. You choose how many days of warning you want, and quiet hours hold anything that would land during your night.
Troubleshooting
If something goes wrong.
Notifications are not arriving
- Allow notifications for Cardper in system settings.
- Check that reminders are enabled per card in the app.
- Confirm quiet hours are not covering the reminder time.
- Turn off battery saver or background restrictions for the app.
Cloud Sync is not updating
- Confirm you are signed in with the same Apple or Google account on both devices.
- Check your network connection, then pull to refresh the card list.
- Open the app on the source device once so pending changes upload.
- Sign out and back in if a device still shows old data.
Restoring a Pro purchase
- Use the same store account that made the purchase.
- Open Settings and tap Restore purchases.
- Check your store subscription page to confirm the plan is active.
- If it is active and Pro is still locked, email us the purchase receipt.
Changing language or currency
- Language follows your device language where a translation exists.
- Set a default currency in Settings, and per card if you hold cards in several currencies.
- Free accounts support one currency. Multiple currencies need Pro.
Deleting your data
- Delete a card to remove its records from the device.
- Uninstalling removes all local data permanently, so export or sync first.
- For synced data, email contact@cardper.com and we will delete it within 30 days.
Privacy and data, in short.
Local first
Your cards live on your phone. Nothing is uploaded unless you turn on Cloud Sync.
Encrypted sync
When sync is on, records are encrypted in transit and only your account can read them.
App lock
Face ID, Touch ID or a PIN keeps the app closed to anyone holding your unlocked phone.
