Contrastly Support

Check that Contrastly has permission to write workouts, either from within the Health app or in Settings under Health, Data Access & Devices. Nothing is written without your permission, and you can grant or revoke it at any time.

These figures are read from Apple Health, so Contrastly needs read permission for them. Check the permissions in Settings under Health, Data Access & Devices, and confirm the data exists in Health for that session.

Private iCloud sync is part of “Pro”, so confirm your subscription or lifetime purchase is active. Also check that iCloud is signed in and enabled for Contrastly on each device.

Open Contrastly, go to the “Pro” screen, and use the restore purchases option there. Sign in with the same Apple account used for the original purchase.

Full CSV export of your whole journal is part of “Pro”. On the free plan, export covers only your last 30 days.

Home Screen and Lock Screen widgets are part of “Pro”. Make sure your subscription or lifetime purchase is active, then add the widget again from the widget gallery.

The latest version is 1.0, released on August 18, 2026. To update, open the App Store, tap your profile picture, pull down to refresh, then tap Update next to Contrastly. You can also turn on automatic updates in Settings › App Store.

Subscriptions are managed by Apple. Open Settings, tap your name, then Subscriptions, and choose Contrastly to change or cancel your plan. Cancel at least 24 hours before renewal to avoid the next charge; deleting the app does not cancel it. Refund requests go through reportaproblem.apple.com and are decided by Apple.

Open Settings › Privacy & Security › Camera (or Photos) and turn on Contrastly. The pictures you attach stay in the app and are never sent to us.

In Contrastly, use the option to delete your data in the app’s settings, where available. Deleting the app removes the data stored on that device. To remove the copy kept in iCloud, go to Settings › [your name] › iCloud › Manage Account Storage, select Contrastly and delete its data.

Please do. Use the form below or write to contact@develak.com. Updates to our apps are often shaped by messages from the people who use them.
