Purchases, refunds, and billing are managed entirely by Apple. We cannot process refunds on our end.
Switched devices or reinstalled the app? Open LatentLens, tap any locked lesson, then tap Restore purchases on the paywall screen.
Go to Settings → [your name] → Subscriptions → LatentLens Pro → Cancel. Access continues until the end of the paid period.
First, make sure you're using the same Apple ID you used to purchase. Then open any locked lesson, tap the paywall, and tap Restore purchases. If the issue persists, force-quit the app and reopen it. Still stuck? Email us with your Apple Order ID (found in your App Store purchase confirmation email) and we'll investigate.
All progress data is stored locally on your device and we have no access to it. If you uninstalled and reinstalled the app, the data was permanently deleted along with the app. Unfortunately we cannot restore progress from our end.
Try these steps in order: (1) Force-quit the app and reopen it. (2) Restart your iPhone. (3) Check for an app update in the App Store. (4) If the issue persists, email us at jtscientific2016@gmail.com and describe which lesson or screen is crashing and your iPhone model and iOS version.
LatentLens v1.0 is designed for iPhone. It will run on iPad via iOS compatibility mode, but the layout is optimised for iPhone. A native iPad version may be added in a future update.
We don't currently offer a separate student pricing tier — but the Lifetime plan at $9.99 is designed to be the most affordable long-term option. Contact us at jtscientific2016@gmail.com if you have a bulk or institutional use case in mind.
Refunds are issued by Apple, not by us. Visit reportaproblem.apple.com, sign in with your Apple ID, find the LatentLens purchase, and select Request a Refund. Apple typically processes refund requests within a few business days.
Thank you — we take accuracy seriously. Email us at jtscientific2016@gmail.com with the lesson name and a description of the error. We review all content feedback for upcoming app updates.
Yes — all lesson content is bundled with the app and works completely offline. An internet connection is only needed to make a purchase or restore purchases (because those go through Apple's servers).
All LatentLens data is stored on your device. To delete everything permanently, simply delete the app from your iPhone. This removes all progress, badges, streak data, and settings. We hold no copy of your data. See our Privacy Policy for details.
