Frequently asked

Support & FAQs

How do I cancel my Premium subscription? +
Subscriptions are managed entirely through Apple. Open Settings on your iPhone, tap your name, then Subscriptions, select LensTracker, and choose Cancel Subscription. Cancelling stops future renewals — you keep Premium access until the end of the current billing period.
What health data does LensTracker access, and where does it go? +
With your permission, LensTracker reads sleep and heart rate variability data from Apple Health to show context alongside your eye care routine. This data is never used to calculate your Eye Health Score, and it's never sold or shared with third parties. AI chat messages are sent securely to generate insights and are not used to train models.
Is LensTracker a substitute for professional eye care advice? +
No. LensTracker is a wellness and habit-tracking tool, not a medical device. It doesn't diagnose conditions or provide treatment guidance. If you're experiencing discomfort, redness, or any eye health concern, please consult an eye care professional.
How do I delete my account and data? +
Go to Settings inside the app and tap Delete Account. This permanently removes your data from your device and from iCloud sync. This action can't be undone.
My barcode scanner isn't detecting a product. What can I do? +
Make sure you've granted Camera access in Settings → LensTracker, hold the barcode flat and well-lit, and try moving slightly closer. If the product still isn't found, you can add it manually from the Products screen.
