Privacy Policy
Last updated: July 17, 2026
1. Who We Are
Gummble ("we", "us") operates gummble.com, a curated library of UI screenshots and design patterns, and the Gummble MCP server, which lets AI assistants search that library. This policy explains what data we collect, why, and the choices you have. Questions go to support@gummble.com.
2. Information We Collect
Account information
When you sign in with an OAuth provider (such as Google), we receive your email address, name, and profile picture. We use this to create and secure your account, associate your subscription with you, and contact you about your account. We never receive or store your password for that provider.
Product analytics
We use PostHog to understand how the product is used: page views, searches, feature usage, and subscription events, along with device and browser information. Approximate location (country and city level) is derived from your IP address for aggregate analytics; we do not track precise location. Analytics data is associated with your account when you are signed in and is used to improve the product, not sold to anyone.
Payment information
Subscriptions are processed by Polar, our payment provider. Your card details go directly to Polar and never touch our servers. We store only what we need to manage your subscription: plan, status, and billing history.
Gummble MCP server
When you connect an AI assistant to the Gummble MCP server, we record which tools are called (for example, a search or a screen lookup), when, and by which account. We do not receive or store the content of your conversations with your AI assistant. The MCP server is read-only: it can search and return content from our library, and it does not store any files or documents of yours.
Cookies
We use cookies to keep you signed in, remember preferences, and power the analytics described above. You can block cookies in your browser; signing in will not work without them.
3. How We Use Your Information
We use the data above to provide and improve the service, authenticate you, process payments, prevent abuse, and communicate with you about your account. We do not sell your personal information, and we do not use it for third-party advertising.
4. Sharing
We share data only with the service providers needed to run Gummble — PostHog (analytics), Polar (payments), and our hosting and infrastructure providers — each bound to use it solely to provide their service to us. We may also disclose information if required by law.
5. Data Retention
We keep account data for as long as your account exists. Analytics and MCP usage data is retained for up to 24 months and then deleted or aggregated. If you delete your account, we delete your personal data within 30 days, except records we must keep for legal or billing reasons.
6. Your Rights
You can request a copy of your data, correct it, or ask us to delete it at any time by emailing support@gummble.com. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA; we honor those requests regardless of location.
7. Security
All traffic to Gummble is encrypted in transit. Access to personal data is limited to the people and systems that need it to operate the service. No system is perfectly secure, so if we learn of a breach affecting your data we will notify you promptly.
8. Changes
We will post any changes to this policy on this page and update the date above. Material changes will be announced by email or an in-product notice.
9. Contact
Email support@gummble.com with any privacy question or request. See also our Terms of Service.
