Subscriptions

How do I cancel?

On your iPhone, open Settings › [your name] › Subscriptions › Hand Lens › Cancel Subscription. You can also get there from the app: Settings › Manage subscription. Cancel at least 24 hours before your trial or period ends to avoid the next charge. You keep Premium until the end of the period you've paid for.

How do I get a refund?

Apple handles payments and refunds. Request one at reportaproblem.apple.com.

I paid but Premium isn't showing

In the app, open Settings › Restore purchases, signed in with the same Apple ID you bought with. There's no account to log into: your subscription is tied to your Apple ID.

Identification

Why does it say "best guesses"?

Some rocks look nearly identical in photos. When the photo match isn't confident, the app shows its suggestions as best guesses with a low confidence level; they can be wrong. If a photo can't be used at all, it says so. Try a sharp close-up in daylight of a fresh, clean surface, or use the test guide: simple tests can help narrow it down, though some specimens stay uncertain without a specialist.

What uses an identification?

Every result with suggestions uses one identification, including low-confidence best guesses. Results saying the specimen isn't in our database don't. For Premium subscribers, up to 2 photos a day that can't be used (too blurry, or not a rock) don't either.

The answer was wrong

Tap "No" under "Was this right?" and, if you know, pick what it actually was. We only receive the rock type and whether it was right, not your photo. These totals show us where the app gets confused.

Do you keep my photos?

Our server doesn't: it discards them right after the identification, and location data is removed before upload. Our AI provider, Google, keeps them for a limited period only to detect abuse and doesn't use them to improve its products. See the privacy policy.

Can it tell me what my specimen is worth, or whether it's safe?

No. The app identifies likely rock and mineral types. Value, authenticity and safety need a specialist who can examine the specimen in person.
