Privacy Policy
Last updated: May 2025
Overview
MockupStack is designed with privacy as a core principle. This policy explains what data we collect (very little), how it is used, and what controls you have as a user.
Image and file data
All image processing in MockupStack runs entirely inside your browser using the Canvas API and Web Workers. Screenshots, images, and compositions you create are never transmitted to any external server. No image data is stored by MockupStack outside of your local browser storage (IndexedDB), and you can clear it at any time by clearing your browser site data for this domain.
Data we do not collect
MockupStack does not collect, store, or transmit:
- Your screenshots or app images
- The text or captions you type into scenes
- Your exported PNG or ZIP files
- Any personally identifiable information
- Device identifiers or persistent cookies tied to your identity
Analytics and cookies
MockupStack may use privacy-respecting, aggregate analytics (such as page view counts) to understand how the tool is used and where it can be improved. These analytics do not track individual users, are not linked to your identity, and do not involve sharing data with advertising networks. No third-party advertising cookies are set on this site.
Local browser storage
The editor automatically saves your current composition to your browser's IndexedDB so you can close the tab and resume later. This data never leaves your device. You can delete it at any time via your browser's site data settings (Settings › Privacy › Clear browsing data › Cookies and site data for mockups.imageandpdf.com).
Third-party services
MockupStack is hosted on Vercel. Vercel may collect standard server access logs (IP address, user agent, request path) as part of normal web hosting operations. Please refer to the Vercel Privacy Policy for details on how infrastructure-level data is handled.
Children
MockupStack is a general-purpose developer tool and is not directed at children under the age of 13. We do not knowingly collect any information from children.
Changes to this policy
We may update this Privacy Policy to reflect changes in the tool or legal requirements. The "last updated" date at the top of this page will be revised accordingly. Continued use of MockupStack after changes are posted constitutes acceptance of the updated policy.
