Privacy Notice

Last updated: 12 November 2026

Scope and contact

Polywick Graphics, PH, Corp., Philippines, operating as Polywick Studio, is responsible for the personal information it handles for margindiff.app and customer communications about MarginDiff products. Contact us for privacy questions or requests.

Information we handle

• Website visits: hosting and network services process connection information such as IP addresses, requested pages and browser details to deliver and secure the websites.
• Enquiries: our MarginDiff contact form and email communications contain the contact details, project information and messages you choose to provide. The contact form uses Netlify Forms.
• Purchases: transaction details can include your name, email, billing information, product, order reference and payment status. Where Paddle provides checkout, it processes payment and tax information and shares relevant order details with us.
• Licensing: products that use online activation may exchange licence and device identifiers with the licensing service to verify entitlements. Refer to the information supplied with that product; local file processing does not necessarily mean activation is offline.
• Support: we receive messages and any logs, screenshots or files you send. Remove passwords, private keys, payment card details and unnecessary confidential or personal information before sending attachments.

Local files and comparison results

MarginDiff documents and comparison files

MarginDiff document comparisons run locally in the Windows application. The MarginDiff marketing website does not provide a document-upload feature. Your source documents and comparison results are not uploaded to Polywick Studio as part of that local comparison workflow.

If you choose to send a sample document, screenshot or diagnostic log for support, we receive that copy and use it to investigate your request. Prefer a small, redacted example and remove unrelated personal or confidential information. Local files and backups on your own computer remain under your control.

MarginDiff activation and checkout

Licence activation sends licence and device-related identifiers to the licensing service to verify activation and manage entitlements. This is separate from the contents of the documents being compared. Paddle handles the checkout details required for payment, tax and fraud prevention; relevant order and payment-status information is shared with us to administer the purchase and support it. Payment card details are entered with the payment provider.

The MarginDiff site loads Google Fonts and loads Paddle checkout when the purchase button is selected. These services receive connection information needed to deliver their content. Checkout may use cookies or similar storage for payment and security functions.

The MarginDiff marketing website and hosted documentation load Google Analytics 4 only after you accept analytics. Google receives page-visit, browser, device and connection information and uses analytics cookies such as _ga. Our website tag disables Google signals and advertising personalization and excludes query strings, fragments and referrer URLs from its initial page-view configuration. This website tracking does not add analytics to MarginDiff desktop applications or send documents or comparison results to Analytics.

Use Analytics preferences at the bottom of the website or documentation to change your choice. It is remembered under diffy-analytics-v1. Rejecting disables further collection and removes accessible analytics cookies on the MarginDiff website hostname; it does not delete data already collected. Google may process information outside your country; see Google's Privacy Policy.

Browser storage and external services

The website remembers your analytics choice in your browser under diffy-analytics-v1 and your light or dark theme under diffy-theme. These preferences are separate from the contents of your local documents.

Read Paddle's Privacy Policy and, for Google-hosted services, Google's Privacy Policy.

Purposes, sharing and retention

We use relevant information to answer enquiries, fulfil purchases, administer licences, provide support, protect services and meet legal and accounting obligations. Depending on applicable law and the activity, processing relies on contractual necessity, legal obligations, legitimate interests in operating and securing our services, or consent where required.

Hosting, email, payment and administrative providers may process information for those purposes, including in other countries. We may disclose information when required by law. We retain it for as long as needed for the relevant request, customer relationship, security or mandatory records, then delete it or remove identifying details.

How long information is needed

Support messages and any supplied samples are kept for handling the issue and relevant follow-up. Purchase and licence records may need to remain available to support an active entitlement, resolve disputes or meet mandatory accounting requirements. Security records are retained for investigation and protection needs. These purposes differ, so there is no single retention period for every record.

You can ask about the records associated with your enquiry or order and request deletion of support attachments. We will explain any applicable retention requirement. Removing information from our systems does not remove a copy independently held by a payment provider or files on your own devices.

Your rights and privacy requests

Depending on applicable law, you may request access, correction, deletion or a copy of your information, or object to or restrict processing. Where we rely on consent, you may withdraw it. Contact us to make a request; we may verify your identity. Record-keeping obligations may limit deletion. You may also contact your local privacy authority, including the Philippine National Privacy Commission.

For information independently held by a payment provider or your organisation, contact that party. We will update the date above when this notice changes.

Use the contact form, state that your message is a privacy request, and identify the product or interaction concerned. We may ask for proportionate information to verify your identity and protect another person's records. Do not send identity documents or sensitive information unless we explain why they are needed.
