For the A13 QPR Beta program, you will have to wipe only if you opt out before receiving the stable QPR build that you are beta testing. See the FAQ I linked to you for more details.
Yeah, I read the facts its still unclear to me can you please explain? is it saying and are you saying if I don't opt out I'll be able to just continue within the beta program and it won't force me to take the stable version that will wipe me?
Will I then forever lose my opportunity to ever revert back without wiping?
How can I opt-out and return to a public Android release?
First, make sure you are running a
beta version of Android.
View devices to find the device you want to remove and click
Opt out. Your device will receive an update within 24 hours that will wipe all user data and install the latest stable public version of Android.
You will not be able to unenroll and revert back to a stable public release version of Android without first wiping all locally saved data on your device. You may also encounter issues restoring a backup.
Note: During the beta program’s release cycle, there will be stable releases to the public (the official platform release followed by Quarterly Platform Releases (QPRs)). When you apply the stable release update for the version you’re beta testing, you can opt out
without a data wipe for a limited time until you apply the next beta update.
