Overview

The Leak protection watermark is a security feature designed to help you protect confidential or restricted flipbooks shared privately.

When enabled, the feature displays the reader’s email address as a visible watermark inside the flipbook player. If someone takes a screenshot or records the screen, the email address of the person who accessed the flipbook will be clearly visible.

This feature acts as a deterrent against content leaks and helps you identify the source if sensitive information is shared without permission.

The watermark works across any private sharing option that identifies the reader individually, not just Readers only. Password-protected sharing is the single exception, because that flow does not identify who is behind the password. Every other private sharing setup keeps the extra traceability layer, so choosing a distribution method no longer means trading away security.

Key benefits

• Leak deterrence: Discourages unauthorized screenshots and recordings

• Reader traceability: Displays the exact email address of the viewer

• Increased accountability: Encourages responsible content usage

• Flexible distribution: Works across private sharing options that identify the reader

• Stronger content protection: Ideal for confidential or restricted materials

Step-by-step guide

1. Open the Share modal

From your flipbook’s Overview page click Visibility to open the Publish your flipbook modal.

2. Set visibility to Private

Under Select visibility, choose:

• Private

This ensures that only selected people can access the flipbook.

3. Choose how you want to share it privately

Under the Private visibility options, pick the sharing option that fits your distribution.

As long as the option identifies each reader by email address, the leak protection watermark is available.

4. Enable Leak Protection Watermark

Scroll within the modal and check the option:

• Add leak protection watermark

Once enabled, the reader’s email address will appear as a visible watermark inside the flipbook player.

5. Click Update

Click Update to apply the changes.

Your flipbook will now display the email watermark for each authorized reader.

Where the watermark applies

The watermark follows the reader, not the sharing method. Any private option that verifies who the reader is can carry it.

• Available: private sharing options that identify the reader individually by email

• Not available: password-protected sharing, because readers are not identified individually in that flow

• Not available: public and unlisted flipbooks, since there is no identified reader to stamp

How the watermark works

When a reader opens the flipbook:

• Their email address appears diagonally across the flipbook player

• The watermark is visible during navigation

• The watermark will also appear in screenshots or screen recordings

This makes it possible to trace the origin of leaked content back to the reader who accessed it.

Note: The watermark is visible inside the flipbook player. It does not modify your original PDF or design file.

Additional tips / FAQs

Does the watermark appear for public or unlisted flipbooks?
No. The feature only works for flipbooks shared privately, through an option that identifies each reader.

Does it work with password-protected flipbooks?
No. Password protection is the one private sharing option without a watermark, because readers are not identified individually.

Can readers remove the watermark?
No. The watermark is automatically generated based on the authenticated reader’s email address.

Does this replace download restrictions?
No. You should combine this feature with appropriate visibility and menu control settings (such as disabling Download PDF) for stronger protection.

Common use-cases

• Internal company reports: Share financial or strategic documents with leadership teams

• Sales proposals: Protect confidential offers sent to specific prospects

• HR documentation: Distribute sensitive employee materials securely

• Product roadmaps: Share future plans with stakeholders without risking leaks

• Investor decks: Maintain control over restricted business information

Troubleshooting

The watermark is not visible

Make sure:

• The flipbook is set to Private

• The sharing option you picked identifies readers by email, and is not password protection

• Add leak protection watermark is enabled

• The reader is accessing the flipbook through their assigned email

The option is not available in my account

The feature is available on Enterprise and selected Custom plans. Contact the Flipsnack team to enable access.

The checkbox is missing for this flipbook

Check which private sharing option is selected. Password-protected sharing does not support the watermark, so the option will not appear there.
