Scope and contact

This notice describes zumola.com, a free drawing and printable-resource workshop. For privacy questions or resource corrections, email admin@yishengting.com. Do not email sensitive personal information or images you cannot share.

Your drawing files

Our square-grid generator calculates its preview and export in your browser. Where an image-grid tool is available, the image is processed in your browser; Zumola does not upload that image or send its name, pixels or contents to Google Analytics. Downloads are saved by your browser. We do not require a visitor account or payment information.

Essential browser preferences

The paper selector stores Letter or A4 under gf-paper. Your analytics choice is stored under zumola-analytics-v1 for up to 180 days. These are browser preferences, not a user account. Clear this site's storage to remove them. WordPress login and editor cookies apply to site administrators.

Optional Google Analytics

Analytics is off until you choose Allow analytics. Rejecting does not restrict any resource. When allowed, Google Analytics 4 receives page views and resource interactions such as download-link activation, paper selection and a completed generator export. A download event indicates that a download was started, not that a file was printed. We omit URL query strings, image contents, user filenames and personal identifiers from our custom events. Google also processes technical data under its own policies. Google Signals and advertising personalization signals are disabled in our GA4 configuration.

You can reopen Analytics choices in the footer and withdraw consent. We honor Global Privacy Control and the browser's Do Not Track setting by keeping our analytics disabled. Revocation stops our future analytics events and removes accessible first-party Google Analytics cookies; it cannot retract events already processed by Google. Learn how Google uses data from partner sites.

Advertising and consent

Zumola's planned advertising provider is Google AdSense. Advertising is enabled only after site approval and the required consent setup. Google and its partners may use cookies or similar technologies to serve, measure and personalize ads according to your choices. Where applicable, a Google-certified consent message provides advertising choices, including rejection and later withdrawal. Advertising consent is distinct from our analytics choice. Free files and answer keys remain available without clicking an ad.

See Google advertising technologies and Google ad preferences. Our analytics preference control does not replace Google's advertising consent message.

Hosting and security

Our hosting and network providers process technical requests, including IP addresses, to deliver and protect the site. Zumola's application access-log format omits query strings, cookies, uploaded images and visitor IP addresses; logs rotate by size. Administrative records and encrypted backups support site operation and recovery. We do not sell a visitor mailing list or run visitor registration.

Teaching and younger users

These resources are intended for self-directed learners, teachers and parents, rather than accounts or social profiles for children. No age, school, student identity or completed worksheet needs to be submitted. Adults can download materials for offline use.
