Who we are
Retrievals is a semantic search engine for the National Gallery of Art's open-access collection. This policy explains what information we collect when you use the site and what we do with it. If you have questions, email us at legal@retrievals.app.
The short version
- We have no accounts. We never ask for your name, email, or payment details.
- We use optional analytics to understand how the site is used and to catch errors.
- We do not sell your data and we do not run advertising.
What we collect
If you accept analytics, we collect automatic usage data while you use the site:
- pages you visit and how you got here (referrer)
- search queries you enter
- device and browser type, and operating system
- an IP address, used to estimate general location and to protect the service
This data is collected through PostHog, Google Analytics, Vercel Analytics, and Vercel Speed Insights only if you accept analytics.
Search queries
When you search, your query text is sent to our backend on Modal, where an AI model embeds it and matches it against the artwork index. We do not store your queries in any database. Modal keeps only transient operational logs. Query text also appears in analytics events we use to measure how search performs if you accept analytics. We do not collect these analytics events if you reject them.
Cookies and tracking technologies
We ask for your choice before loading optional analytics. If you accept, the providers below may store information on your device or receive usage data. If you reject, PostHog stays opted out and Google Analytics, Vercel Analytics, and Speed Insights do not send usage data. A first-party cookie remembers your choice.
- PostHog — product analytics and error tracking
- Google Analytics — website usage measurement
- Vercel Analytics and Speed Insights — page performance measurement
We do not use advertising cookies, marketing pixels, or cross-site tracking. You can change your analytics choice using the button above, or email us at legal@retrievals.app.
Sharing with third parties
We share data only with the services that run the site, each under its own privacy policy:
- Vercel — hosting, analytics, speed insights
- Google — Google Analytics usage data
- PostHog — product analytics and error tracking
- Modal — serverless compute that embeds queries and searches the index
- Cloudflare — object storage that serves artwork thumbnails
We do not sell your information.
Data retention
We retain analytics data according to each provider's default retention settings. Because we have no accounts, there is no personal account data to keep. Search queries are not stored by us.
International transfers
The site is hosted on Vercel's infrastructure, and our analytics providers process data in the United States and other regions. If you are in the European Union, the UK, or elsewhere outside the US, your data may be transferred to and processed in the US.
Your rights
Depending on where you live, you may have rights under the GDPR, the CCPA/CPRA, or similar laws, including the right to access, correct, delete, restrict, or export your data, and to object to its use. To exercise any of these, email legal@retrievals.app. We respond within the time the law requires.
Children
Retrievals is not directed to children under 13, and we do not knowingly collect information from them.
Changes
We may update this policy. When we do, we'll revise the “Last updated” date above. Significant changes will be highlighted on the page.
