In the menu bar above the document management, there is a gear icon that opens the app's settings. The settings are divided into different sections. All configuration options are described below.

General

This section configures the app's general functions.

Option

Description

Working Folders

This button opens the settings for configuring the working folders.

Disabled: Changes are not saved automatically. Saving must be explicitly confirmed or declined when closing.

Default: Disabled

Show Toolbar

Specifies whether the toolbar is displayed in the document view.

Enabled: The toolbar is displayed.

Disabled: The toolbar is completely hidden. The functions contained in the toolbar can no longer be used. Signing is then only possible by tapping the signature fields individually.

Default: Enabled

Capture Images

Specifies which options are available for capturing an image using the "Images" tool.

Use Camera: Images can only be captured using the camera.

Use Gallery: Images can only be selected from the gallery.

Insert on New Page: The selected image is always inserted on a new page.

Selection Dialog: A selection dialog appears in which you can choose between "Place Freely" and "Insert on New Page".

Default: Selection Dialog

Share











Specifies when it is possible to share the document or forward it to other apps.

Always Available: The "Share" function is always available.

Only When All Signatures Have Been Made: The "Share" function is only available if the document contains at least one completed signature and no empty signature fields.

Only When All Required Signatures Have Been Made: The "Share" function is only available if the document contains at least one completed signature and no empty required signature fields.

Default: Always Available

Append Timestamp to File When Saving

Specifies whether a timestamp is automatically appended to the file name when saving.

Disabled: The original file is overwritten. The file name remains unchanged.

Enabled: A new file is created with the original file name and a timestamp in the format _yyyy-MM-dd_HHmmss (e.g. [...]_2026-06-30_143052). If the file already has a timestamp in the same format, it is not appended again but updated to the current time; the existing file is overwritten in the process.

If the file cannot be saved to its original source directory, it is automatically saved instead in the app’s "Dokumente" working folder.

Default: Disabled

Signature

This section configures signature settings.

Option

Description

Signature Color

Sets the color of the pen used to capture signatures.

Default: Blue

Signature with Pen Only

Specifies whether signatures may only be captured using an electronic pen (e.g. Apple Pencil).

Enabled: Signatures can only be captured using a pen. Signing using touch is not possible.

Disabled: Signatures can be captured using a pen or touch.

Default: Disabled

Start Signing Immediately

Specifies whether the signing process should start immediately after the document is opened.

Enabled: The signing process starts immediately after opening if the document contains at least one empty signature field.

Disabled: The signing process does not start automatically.

Default: Disabled

Signature Additions

This button opens the settings for signature additions.

Default: Disabled

Options for Signature Additions:

  • Show Timestamp: Specifies whether a timestamp is displayed in the signature.
    Default: Disabled

  • Capture Signer for the Signature: Specifies whether the signer’s name must be captured when signing. When enabled, a dialog for entering the signer’s name is displayed before signing. The name is then added to the document in plain text together with the signature. The app remembers the most recently used name while editing the document.
    Default: Disabled

  • Color: Sets the color of the signature additions.
    Default: Gray (#AAA)

Lock Form Fields

Specifies which form fields are locked with the first signature in the document.

Lock All Fields: The signature locks all form fields in the document, regardless of the document’s settings.

Lock Fields Defined in the Document: The signature locks all form fields defined in the document or within the signature field.

Lock Filled-In and Defined Fields: The signature locks all form fields defined in the document or within the signature field. In addition, all filled-in form fields are locked.

Default: Lock Filled-In and Defined Fields

Capture Location

Specifies whether location data is stored in the signature.

Enabled: Location data is captured and stored in the signature.

Disabled: No location data is captured.

Default: Disabled

Capture Biometric Data

Specifies whether biometric data of the signature is captured.

Enabled: Biometric data of the signature is captured and stored encrypted in the document.

Disabled: No biometric data of the signature is captured.

Biometric data is an essential part of the security and authenticity of electronic signatures and is very important for later evidentiary purposes. For GDPR-compliant capture and storage of this data, a confirmation text can, for example, be configured in the software before the signature.

Default: Enabled

Automatic Signature Fields

This button opens the settings for automatically creating signature fields.

Create Signature Fields: Specifies whether the app should automatically create signature fields.

Search Term: Defines a search term for signature fields. A signature field is automatically created at every point in the document where this search term is found.

The search term is searched for in the PDF file’s source code. This means the term can also be inserted "white on white" and thus invisibly in the document.

Default: Disabled

Signature Certificate

This button opens the settings for the signature certificate used for digital signatures.

A new self-signed certificate can be created, or an existing (or purchased) certificate can be imported.

To obtain the "green checkmark" in Adobe Acrobat Reader, you need a certificate whose ROOT is part of the global trust lists "AATL" or "EUTL". Such certificates are generally subject to a fee. For more information, contact the signotec sales team.

Default: Empty

Biometric Certificate

This button opens the settings for the biometric certificate used to encrypt the biometric data.

A new self-signed certificate can be created, or an existing (or purchased) certificate can be imported.

By default, a public-key certificate for encrypting the biometric data is included, the private part of which is securely held by a notary. Not even signotec, as the manufacturer, has access to this private key, so only the notary is able to decrypt the signatures.

Changing the certificate can have a significant impact on the security and authenticity of the signatures. The default certificate should only be replaced if a certificate with equivalent security regarding safekeeping can be guaranteed.

Default: Notarial certificate from signotec

Archiving

This section configures archiving settings.

Option

Description

Archive Type

Specifies how documents are archived.

File Archiver: Documents are stored in the "Archiv" working folder.

Upload Archiver: Completed documents are uploaded to a configured URL via multipart upload.

The upload is performed as a multipart upload (HTTP/HTTPS). The file is passed in the field name "file" within the "Content-Disposition". At the time of archiving, the web server must be reachable and must explicitly accept this upload.

Default: File Archiver

Upload URL

Specifies which server should receive the multipart upload with the archived document.

This option is only available if the archive type "Upload Archiver" has been selected.

Default: Empty

Automatic Email

This button opens the settings for automatically sending an email when archiving a document.

The SMTP details of the email account must be entered for sending.

Send Email: This button enables or disables automatic email sending.

Username: Username for authenticating with the SMTP server.

Password: Password for authenticating with the SMTP server.

SMTP Server: Address of the SMTP server.

Use SSL: Explicitly enables an encrypted connection to the SMTP server.

Port: Port of the SMTP server. Usually "587".

Sender: Sets the sender address. This may differ from the username mentioned above.

Recipient: Sets the recipient of the automatic emails.

Automatically Read Email Addresses: This button determines whether email addresses are automatically read from the document. When this function is enabled, the form fields named "signotecMail1", "signotecMail2", and "signotecMail3" are read from the document and used as the email recipient ("SendTo"). If a static email address is already set for the recipient, the addresses read from the document are used as a copy ("Cc").

No syntax or plausibility check of the content is performed.

Subject: Sets the subject of the automatic emails.

Message: Sets the message of the automatic emails.

The "Test Connection" button sends a test email to the configured sender. If the email is not delivered, the settings must be checked.

Default: Disabled

Append Timestamp to File

Specifies whether a timestamp is appended to the file name when archiving.

Enabled: The file name is extended with a timestamp in the format "yyyy-MM-dd_HHmmss".

Disabled: The file name remains unchanged when archiving.

Default: Disabled

Archive

Specifies when the function for archiving a file is available.

Always Allow: A document can always be archived (without any additional condition).

When All Signature Fields Are Signed: Archiving the document is only possible if all signature fields are signed.

When All Required Fields Are Signed: Archiving the document is only possible if all required signature fields are signed.

Default: Always Allow
