RECALL ENGINE SUPPORT
How to reach us
Use the contact form at kplr-ip.com/contact and put “Recall Engine” in the first line. We respond within two business days.
I paid and the cards are still locked
Open the Subjects tab and tap any locked subject, then tap Restore Purchases on the sheet that appears. Make sure the device is signed in to the same Apple ID you bought with. That resolves nearly every case.
If it does not, send us the date of purchase and the Apple ID email you used, and we will work through it with you.
How do I cancel my subscription
Through Apple, not through us. On your iPhone open Settings, tap your name at the top, tap Subscriptions, select Recall Engine, then Cancel.
Cancel at least 24 hours before your current period ends to avoid the next charge. You keep access until the end of the period you have already paid for.
Deleting the app does not cancel the subscription.
How do I get a refund
Apple collects the payment, so Apple issues refunds. Go to reportaproblem.apple.com, sign in with your Apple ID, find the charge, and request a refund.
We cannot refund a charge we never received, but if you think you were billed in error, contact us and we will help you pursue it.
I think a card is wrong
Please tell us. At the bottom of any answer screen there is a Report a problem with this card link. Tap it, pick what is wrong, add a note if you want, and send. The report includes the card ID so we can find it immediately.
Corrections go out to everyone in the next content update. This is the fastest way to improve the deck and we read every one.
I have a code
Open the Subjects tab, tap a locked subject, then tap Redeem a Code on the sheet. Enter the code exactly as you received it.
Codes are redeemed through the App Store, so you will need to be signed in to your Apple ID.
My progress disappeared
Your study progress is stored on your own device and is never sent to us, which means we have no copy of it and cannot restore it. It is lost if you delete the app, clear your device data, or move to a new phone.
It also does not sync between devices, or between the app and the web version. This is the tradeoff for an app that collects nothing about you.
Does it work without internet
Yes. All 3,450 questions are inside the app. It makes no network requests at all and works in airplane mode. The only thing that needs a connection is a purchase or a restore, because those go through the App Store.
What do you collect about me
Nothing. No account, no sign in, no analytics, no tracking, no advertising identifiers. Everything stays on your device. Full detail is in the Privacy Policy.
Which devices does it run on
iPhone. There is also a web version at kplr-ip.com, though progress does not carry between the two.
