To fully delete your PlantIn/Plantln account and data, you can’t just uninstall the app — that only removes the app from your phone, not your data or subscription.
First cancel your subscription in the app or website Settings → Membership/Subscription so it stops auto-renewing, and also cancel any purchase in Google Play or the App Store if you bought it there.
Once the subscription is cancelled, look in the app Settings → Privacy (or your online account’s Subscription/Billing section) for a “Delete Account”/“Unsubscribe” option to remove your profile and stored data permanently.
Many users report this path is required to stop both billing and data retention. If you’ve faced a similar issue, don’t hesitate to share your story here. You can also file a complaint on Xolvie to seek a resolution.
