Hi — I'm the developer (Zhang). The fastest way to reach me is email:
Settings → Apple ID → Subscriptions → Lift → Cancel. Apple handles all subscription billing — I cannot cancel for you.
Make sure you're signed into the same Apple ID that bought the subscription. Open Lift → Settings → Restore Purchases. If still not working, email me with your Apple ID's email address (so I can confirm) and a screenshot.
Trials auto-convert if not cancelled. If yours was cancelled and you'd like to subscribe, open Lift → Settings → Manage Subscription and pick a tier. Apple's "one trial per Apple ID" rule means you can't trial again.
Pro+ exports CSV. Open Lift → Settings → Export Data. The file is shared via the standard iOS share sheet (AirDrop, Files, Mail, Slack, etc.).
Yes, with Pro+ and iCloud enabled. Settings → Sync → toggle iCloud Sync on. Sync uses your iCloud quota; Lift's data is small (well under 1 MB per year of training).
If you have Pro+ + iCloud sync on, install Lift on another iCloud-signed device and your data will appear. If you don't have sync on and deleted the app — unfortunately the data was on-device only and is gone. We do not operate any servers from which to recover it.
Only if you opt in. Reading heart rate (Apple Watch) and writing one Workout sample per session to the Health app. You can turn it off any time in Settings → Privacy & Security → Health → Lift.
Send it to jasperabundant@gmail.com. I read every email.
