Cempasuchil works fully offline: your altar, your loved ones' cards and your archive all live only on your phone. Below are answers to the most common questions, and a form if you need to reach us directly.
Frequently asked questions
I lost my loved ones or my altar after reinstalling the app.
Cempasuchil stores everything only on your device, with no account and no backup server, so removing the app removes its data too. Back up your device with iCloud or Finder/Finder backups to keep that data safe across reinstalls.
Why does the app ask for the camera or photo library?
Only to let you attach a photo to a loved one's card. The camera is used only when you tap to take a picture, and nothing leaves your device.
Why aren't my reminders arriving?
Check that notifications are allowed for Cempasuchil in Settings → Notifications, and that the reminder is switched on in the app's Nights tab.
How do I change which nights my family observes?
Open the Nights tab, tap any night to edit its date and who it honours, or add a new one.
Can I move my data to a new phone?
Yes — restore from an iCloud or Finder backup of your old device when you set up the new one, and Cempasuchil's local data comes with it.
