1. Open the backup screen in Chalkmark and save a backup file to Files or iCloud Drive.
2. To restore, choose a backup file. Merge adds what is missing and changes nothing else. Replace swaps everything and first shows what the file contains, and keeps a safety copy of your current data.

The app also keeps automatic copies daily and before every restore, but those are deleted with the app, so save a file elsewhere too. Backups do not include progress photos or Apple Health values.

Chalkmark can read exports from Strong, Hevy and FitNotes, and notes you paste in. If a file has weights with no unit, you are asked kilograms or pounds. Lines it cannot read with confidence are shown for review, never guessed, and you get a report at the end. Timed and distance sets are not imported yet and are listed in the report.

By default, none. Your log, plans, photos and chat stay on your iPhone, and Apple Health values are read on demand and never stored by Chalkmark.

If you turn on cloud help, a question sends your chat messages and the results of the lookups Chalk runs on your log to answer it. That can include your body-weight trend (which can come from Apple Health body mass) and the injury and preference notes Chalk remembers. Importing sends the text you paste. Photos, location and raw Health samples (sleep, heart rate variability, heart rate, respiratory rate) are never sent. The messages go through our server, which stores nothing, to OpenRouter and on to a model provider. See the privacy policy for the full list.

Cloud help is off until you agree to it. To turn it off, switch it off in the app's Settings. That stops all sending at once, including a reply in progress. Logging and the on-device coach keep working.

Yes. Logging, history, plans and the training engine work on every supported iPhone with no model. Chat needs the on-device model or optional cloud help.

Not yet. Your data lives on one iPhone, so back up regularly.

If you are in the TestFlight beta, use TestFlight's “Send Beta Feedback” (you can attach a screenshot), or email us. Say what you typed, what you expected and what happened. Please do not send backup files unless asked.
