{% endhint %}
## Save changes
Tap 
**Save** to save the changes you have made. Tap 
**Back** to return the **Map** view.

In Mapeo Mobile, you can only delete observations that have been created on your device.
{% endhint %}
{% hint style="danger" %}
**Deleting observations cannot be undone, so exercise caution when using delete.**
As Mapeo uses a peer-to-peer database, all data is stored directly on your device and there is no backup on a centralized server. By deleting observations, you will permanently remove them from your device and all devices you synchronize data with in the future.\
