Before you revert to the public version, you can check to make sure that your data is saved correctly on the server by signing in with your Kindara login here: https://app.kindara.com/
Click the menu button in the upper right corner, then click Charts. If you see all the data you expect in your charts on the website, your data is synced with the servers!
To revert to the public version, sign out of the beta version, and delete the app from your phone. Then open the Apple App Store or Google Play Store on your device, download Kindara, and sign back into your account.
