Terms of Service

Last updated: 12 November 2026

Who we are and what these terms cover

Polywick Graphics, PH, Corp., Philippines, operating as Polywick Studio, provides these terms for margindiff.app and the MarginDiff products described on this website. Review our purchase details. Contact us with questions. Separately agreed custom-development services are governed by their written agreements.

Purchases and licences

Before paying, review the selected product, price, currency, taxes, payment frequency, licence scope and delivery arrangements in the offer and order. A one-time purchase and a subscription are different arrangements; these terms do not convert one into the other. Renewals, cancellation, included updates and support must be stated in the applicable offer.

Your software licence and written order define permitted use and installations. Purchasing one product does not grant access to every Polywick product. Ownership of the software is not transferred. Any open-source components remain subject to their own licences.

MarginDiff Documents purchases

The current MarginDiff Documents offer is US$99 as a one-time payment for the Windows product. It is not an automatically renewing subscription and does not include MarginDiff Sheets, MarginDiff Presentations or MarginDiff Scrub. Applicable taxes and the final total are shown before payment. Check the selected product and order before confirming.

Features and installers marked “coming soon” or “in development” are not immediately available. Confirm delivery arrangements before purchasing if they are unclear. A roadmap description is not an entitlement to an unreleased feature.

Payments through a reseller

Where a checkout identifies Paddle as the seller, Paddle acts as the authorised reseller and its Buyer Terms also govern the transaction. Other purchases follow the seller and payment arrangements identified in the order.

Responsible use

Keep your order confirmation and use accurate contact information so the seller can send receipts and purchase instructions. For missing delivery, activation problems or an incorrect order, use our Product Inquiry form and include the order reference. Never send payment card details or passwords.

Use the software lawfully and only with files, systems and content you are authorised to access. Protect credentials, keep suitable backups and configure access appropriately. You are responsible for your content, deployment and decisions made using software output. Do not use our services for malicious activity or unauthorised access.

Compatibility and support

Check the product's requirements before purchasing. Features, supported formats and integrations differ by product and release. Support and any response-time or availability commitments are those expressly included in your order; no universal service-level commitment is made here.

Your files and comparison results

You retain ownership of your documents and results. Using MarginDiff does not transfer those rights to Polywick Studio. You must have permission to process the files you use, including files containing another person's information.

MarginDiff is a review aid. Comparison results depend on the source files, selected options, supported features and any conversion or text-recognition tools involved. Review the results before relying on them and keep original copies. Software output does not replace professional review where your work requires it.

Third-party requirements and licence scope

Some workflows require separately licensed software or services, such as Microsoft Office or text-recognition tools. Their licences, charges and availability are separate unless the purchase offer expressly includes them. A product licence does not grant rights to third-party software.

Permitted users, devices, transfers and upgrade rights are determined by the licence supplied with your order. Contact us before purchasing if those terms do not address your deployment. We do not imply unlimited installations or lifetime access to future releases.

Refunds and statutory rights

Read our Refund Policy and the applicable product details. Nothing in these terms removes mandatory consumer rights or excludes liability that cannot legally be excluded.

Privacy and updates

Our Privacy Notice explains website and customer-data handling. We will date revisions to these policies. Updates do not retrospectively remove rights agreed for an existing purchase.
