Write to hi@pitterapps.com and a person answers. Below are the questions that come up most, with the answer you would otherwise have to wait for.
Contact
hi@pitterapps.com — please say which phone you are on and what happened just before the problem. That is usually enough to find it.
How do I cancel?
It depends on where you subscribed, and it is not the same place:
- On this website — the payment runs through Stripe. Use the management link in your purchase confirmation email, or write to us and we will send it again.
- In the app on iPhone — iOS Settings → your name → Subscriptions.
- In the app on Android — Google Play → Subscriptions.
Cancel at least 24 hours before the period ends. The period you already paid for runs to its end.
I paid on the website and the app is still locked
Open the activation link from your confirmation email on the phone that has Lufa installed. It hands the subscription over. The link is valid for 60 minutes; if yours has expired, write to us and we will send a fresh one.
If the app is already open, try Settings → Restore purchases first.
The distance looks wrong
GPS needs a clear view of the sky and about a minute to settle. Under trees, between tall buildings, or on a treadmill it will be off — on a treadmill it measures nothing at all, and the app shows “Location off — timing only” instead of inventing a number.
Check that Lufa has Location → Always or While Using, and that Precise Location is on. Without it the session still runs on time alone.
I cannot hear the voice cues
Check the mute switch and the volume during a session, not before one. Lufa ducks your music rather than stopping it, so a cue plays quietly over a loud track. If a cue is still too quiet, turn Announce interval changes up by raising the media volume mid-session — Lufa speaks at the system media level.
I missed a week
Nothing is lost. The plan notices and offers to step you back: after about a week away, one week back; after three, it restarts the week you were on. You can decline and carry on where you were.
How do I delete my data?
Delete the app. Everything Lufa knows about you is on the device — there is no account and no server copy. Settings → Start over clears the plan and history without uninstalling.
