Privacy Policy
Effective Date: October 30, 2026 · mengmengtools.com
1. Privacy First Architecture (Local-First Design)
At mengmengtools.com, we believe your commercial data, product feature roadmaps, and competitive intelligence should remain strictly private. The "Us vs. Them — Product Comparison Table Builder" Figma plugin is engineered from the ground up as a local-first tool.
All data parsing (Excel, CSV, TSV, Markdown), layout calculations, color theming, and Figma Auto Layout node generation are executed 100% locally inside your Figma client sandbox.
Summary of What We DO NOT Collect:
- We do NOT transmit or upload your table content, headers, prices, or feature text.
- We do NOT operate external database servers to store user documents.
- We do NOT track your Figma document names, file URLs, or canvas selections.
- We do NOT use tracking analytics, telemetry SDKs, or session replay tools.
2. License Verification & Gumroad Communication
The only external network communication initiated by the plugin occurs when you explicitly enter and verify a Pro License Key:
-
Endpoint: The plugin makes a secure HTTPS request directly to Gumroad's official API (
https://api.gumroad.com/v2/licenses/verify). - Payload: Transmits strictly the license key entered by the user and the product identifier to verify purchase validity and active status (e.g., ensuring the key is not refunded or chargebacked).
-
Local Caching: Once verified, your authorized Pro status is stored locally in your personal Figma client storage (
figma.clientStorage) so you do not need to re-verify during routine offline design sessions.
3. Payment Information
Payment transactions for Pro licenses are processed entirely by Gumroad. We never receive, process, or store your credit card numbers, billing addresses, or banking credentials. Gumroad handles all payment security in compliance with industry PCI-DSS standards. For more details, refer to Gumroad's Privacy Policy.
4. Cookies and Website Tracking
The promotional website at mengmengtools.com does not use advertising tracking cookies, cross-site trackers, or third-party marketing pixels. We respect your browsing privacy.
5. Children's Privacy
