Frequently asked
Does Nefsera provide medical treatment?
No. Nefsera is a general wellness and habit-support app. It is not a medical device and does not provide diagnosis, treatment, cure or prevention of any disease.
Where is my data stored?
In the current version, your quit plan, journal, cravings and other in-app records are stored locally on your device. See our Privacy Policy for the full list.
How do I delete my data?
You can review or delete local data in the app's Settings, or by uninstalling Nefsera. Any operating-system backups you have enabled are outside the app and follow your device settings.
How do subscriptions work?
Subscriptions and one-time purchases are handled by Google Play Billing. You can manage or cancel your subscription any time in the Google Play Store, under Subscriptions.
I changed my phone or reinstalled the app. Where is my data?
Local data lives on the device it was created on. If you did not have a system-level backup enabled, reinstalling or switching devices may mean starting fresh. There is currently no account-based cloud sync.
What if I have a medical emergency?
Nefsera is not an emergency service. If you or someone else is in danger or having a medical emergency, contact your local emergency services immediately.
