For a bug, include your iPhone model, your iOS version and your Basalt version — it saves a round trip.

My subscription is not recognised

Open Basalt+ in the app and tap “Restore purchases”. Basalt has no account: restoring goes through the Apple account the purchase was made with. If you changed Apple ID since, the subscription stays with the old one.

How do I cancel Basalt+?

In your iPhone settings: your name, then Subscriptions. Cancellation happens at Apple, not with us — we have no way to touch it. Deleting the app cancels nothing. See the terms of use.

I smoked. Do I lose everything?

No. The counter never restarts from zero. The Stone dims and relights on its own over twenty-four hours, and the cigarettes you declared are subtracted from your figures. If you declared a slip by mistake, open the counter sheet: “Undo the last slip” removes it.

My figures look wrong

Tap any number on the Today screen: Basalt shows its arithmetic, with your own figures, the source used and its margin. The same sheet offers “Correct my declaration” if your consumption or your pack price has changed.

How do I delete my data?

Delete the app. Everything you declared lives in its private storage, on your device, and goes with it. We hold no copy — see the privacy policy.

What languages does the app speak?

English and French. Basalt follows your iPhone’s language.

An emergency, a craving that will not pass

Basalt is not a medical service. In France, Tabac info service — 39 89 connects you with a cessation specialist, free of charge. Elsewhere, ask your doctor or your national quit line.
