Your data stays on your device
3DCDesign has no account and no server copy of your records, so you are in charge of them.
- Your records live in the app on your phone or tablet.
- To delete a record, open it in the app and delete it. Before you uninstall, delete your printer connections so their saved passwords are removed too. Uninstalling removes the app's records and files. On iPhone and iPad a few small settings, such as your profile name, can stay in the device keychain.
- Backup files you saved stay where you saved them. Delete them there too.
- Apple or Google may keep app data in your device backup, depending on your settings.
- There is no account to close and nothing to ask us to delete.
