Terms of Service

Acceptance of Terms

By accessing or using this service (the "Service"), you agree to be bound by these Terms of Service. If you do not agree, please do not use the Service.

Description of Service

The Service consists of three browser-based tools that remove watermarks from files you created or are otherwise authorized to edit. Processing runs entirely in your browser: your files are never uploaded to or stored on our servers, and the only data we receive is a lightweight download record (file name, file size, a non-reversible fingerprint, and a timestamp) used to deduct credits.

• PDF slide-deck watermark removal — pdf-watermark-remover: removes the "Made with NotebookLM" marking from slide-deck PDFs that you exported yourself from NotebookLM.
• PPTX slide-deck watermark removal — pptx-watermark-remover: removes the "Made with NotebookLM" marking from .pptx decks that you exported yourself from NotebookLM. Slide images are repaired in place, so the deck stays editable and its speaker notes and animations are preserved.
• Video watermark removal — video-watermark-remover: removes the on-video watermark from MP4 files you provide. The tool also detects and trims the generic NotebookLM outro card at the end of the video (usually the final 2–3 seconds), and the trimmed result is the file you download.

Scope. The Service does not convert documents, notes, or notebooks into presentation slides, does not convert files from one format to another, and does not generate text, images, audio, or video with AI. It only removes watermarks, and trims the closing NotebookLM outro card (usually the final 2–3 seconds), as described above. We are not affiliated with, endorsed by, or sponsored by Google LLC; NotebookLM is a trademark of Google LLC.

User Accounts

You are responsible for maintaining the confidentiality of your account credentials and for all activities under your account. Notify us immediately of any unauthorized use or security breach.

Acceptable Use

You agree not to:

• Violate any applicable laws or regulations.
• Infringe on the intellectual property or other rights of any party.
• Attempt to gain unauthorized access to our systems or data.
• Interfere with or disrupt the integrity or performance of the service.
• Use the service to send spam, malware, or other harmful content.

Payment and Billing

The Service is prepaid. We sell one-time credit packs only: there is no recurring subscription, and credits never renew automatically. Prices, credit amounts, and any validity period are shown before checkout. You are responsible for providing accurate billing information.

Processing requires no credits. Credits are deducted only when you download a processed file, in the amount displayed on the tool page at the time of use: currently 10 credits per slide deck download (PDF or PPTX) and 20 credits per video download. If processing fails, or if you do not download the result, no credits are deducted. If your balance is insufficient, the download does not proceed and no credits are deducted.

Each processed result is charged at most once: downloading the same processed file again does not deduct further credits. Processing the same file again creates a new result, which is charged again.

Prices may change with prior notice; changes never affect orders already completed.

Refund Policy

All sales are final. Purchases are non-refundable once the order is completed and credits have been delivered to your account, except as expressly stated below:

1. Duplicate charge. If you were charged more than once for the same order, we will refund the duplicate charge in full.
2. Non-delivery or system failure. If credits were never added to your account, or a confirmed system failure prevented the Service from working at the time of purchase, we will re-credit your account or refund the affected amount.
3. Required by law. Where applicable consumer-protection law grants you a statutory right of withdrawal, we will honor it.

To request an exception, contact us at the support email listed in the Contact section below within 7 calendar days of the charge, and include the order number from your payment receipt. We review requests within 3 business days. Approved refunds are returned via the original payment method, typically within 5–10 business days depending on your payment provider.

We do not currently offer recurring subscriptions. If we introduce subscription plans in the future, they may be canceled at any time from your account settings; cancellation stops all future renewals, and the current billing period remains active until it ends. The current period is non-refundable except under the exceptions above.

If you have consumed part of your credits, the unconsumed portion may be refunded pro rata solely at our discretion under the exceptions above; consumed credits are non-refundable.

Intellectual Property

The Service and its original content, features, and functionality are owned by us and are protected by international copyright, trademark, and other intellectual property laws. You retain full ownership of the files you process. Because processing happens locally in your browser, we never receive, store, or claim any licence over your files.

You are responsible for ensuring you have the right to edit any file you process. The Service is intended for files you created or are otherwise authorized to modify; do not use it to remove attribution from content you do not own or have permission to alter.

Termination

We may suspend or terminate your access to the Service at any time if you violate these terms. You may close your account at any time through your account settings. If we terminate your account for reasons other than your breach, unused credits will be refunded pro rata.

Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of your use of or inability to use the Service.

Changes to These Terms

We may modify these Terms at any time. We will notify users of any material changes by updating the date at the top of this page and, where appropriate, sending a notice through the Service.
