InkProof

Print preflight checker for Canva — catch issues before you print.

About InkProof

InkProof is a free Canva app that checks your design for common print production issues before you send it to the printer. With one click, it scans for safe zone violations, low-resolution images, CMYK-unsafe colors, and print dimension problems.

InkProof runs entirely inside Canva's editor. It does not collect, store, or transmit any user data. There is no backend server, no analytics, and no account required.

Privacy Policy

Effective date: March 5, 2026

Data Controller

InkProof is operated by Jeff Michael Johnson, located in the State of Michigan, United States. For all privacy-related inquiries, contact: [email protected].

Overview

InkProof is committed to protecting your privacy. This policy explains how the app handles information when you use it within Canva.

Data We Collect

None. InkProof does not collect, store, process, or transmit any personal data or user information.

How the App Works

Legal Basis for Processing (GDPR)

To the extent any processing occurs, it is based on legitimate interest in providing the requested preflight analysis service. All processing is performed entirely on your device within your browser and no data is transmitted to any external server.

Third-Party Services

InkProof does not integrate with or send data to any third-party services, APIs, or servers.

Image Access

InkProof temporarily accesses image URLs provided by Canva's asset API solely to measure image resolution for the print quality check. These URLs are loaded in your browser to read pixel dimensions and are not stored, logged, or transmitted anywhere.

Design Modifications

When you run a print check, InkProof may add temporary colored rectangles to your design to visualize the print safe zone. These overlay elements can be removed with a single click or by using Canva's undo feature. InkProof does not modify or delete any of your existing design content.

Data Retention

Not applicable. InkProof does not store any data. All analysis is performed in real time in your browser and discarded immediately upon completion. No information persists after you close or navigate away from the app.

International Data Transfers

Not applicable. InkProof does not transfer any data outside your device. All processing occurs locally in your browser.

Your Rights Under GDPR

If you are located in the European Economic Area (EEA) or the United Kingdom, you have the right under the General Data Protection Regulation to access, rectify, erase, restrict processing of, and port your personal data, as well as the right to object to processing and to lodge a complaint with your local supervisory authority. Because InkProof does not collect or store any personal data, these rights do not apply in practice. If you believe we hold any of your data in error, please contact [email protected] and we will promptly investigate.

Your Rights Under CCPA / CPRA (California)

If you are a California resident, you have the right under the California Consumer Privacy Act and the California Privacy Rights Act to know what personal information is collected, to delete it, to opt out of its sale or sharing, and to not be discriminated against for exercising your rights. InkProof does not collect, sell, or share any personal information. No personal information is used for cross-context behavioral advertising. For questions, contact [email protected].

Children's Privacy

InkProof does not knowingly collect any information from anyone, including children under 13. Because InkProof does not collect or store any information, this scenario is not technically possible. If we become aware that we have inadvertently received personal information from a child under 13, we will delete such information immediately.

Changes to This Policy

If this policy is updated, the revised version will be posted on this page with an updated effective date. For material changes, we will update the effective date and, where possible, provide notice through the Canva app listing or this website.
