Disable the 'Save to Device' Option Before Signing

Prevent your signature from being stored locally by toggling off the save feature directly in the signature panel before creating it.

When using Adobe Fill & Sign, you have the option to keep your signatures from being stored permanently. This is especially useful for users who share devices or prefer not to keep sensitive signatures stored in an app.

Open the Signature Panel

Launch the Adobe Fill & Sign app on your iOS device, open a document, and tap the pen icon to access the signature menu.

Turn Off 'Save to Device'

Before you draw or type your new signature, locate the 'Save to Device' switch at the bottom or top of the signature screen and toggle it to the OFF position.

Create Your Signature

Draw your signature as usual and apply it to the document. Because the switch was turned off, this signature will only be used for the current session and will not be stored locally.

Disable the 'Save to Device' Option Before Signing

Adobe ID Syncing: If you are signed in with an Adobe ID, your signature may still sync across devices. You should review your app's account and synchronization settings to fully prevent cloud storage.

Frequently Asked Questions

Why does my signature keep syncing across my devices?

If you are signed into the Adobe Fill & Sign app with an Adobe ID, the service automatically syncs your saved signatures across all devices using that same ID. To stop this, you must sign out or adjust your Adobe account synchronization settings.

Can I delete a signature that has already been saved in Adobe Fill & Sign?

Yes. Tap the pen icon to open the signature panel, tap the minus icon (-) or the delete button next to the previously saved signature, and it will be permanently removed from your device.

Does turning off 'Save to Device' delete my previous signatures?

No, toggling off the 'Save to Device' switch only prevents the current or newly created signature from being saved. You must manually delete any previously stored signatures from the signature panel.
