Privacy Policy

Last updated 17 October 2026

This policy explains what data Glanzz ("we", operated by VALUE) collects when you use the app at this site, how we use it, and the choices you have. Glanzz predicts visual attention on images, web pages and videos; the heatmaps and scores it produces are AI estimates, not measured human eye-tracking.

What we collect

Account data. Your email address, an optional name, and a securely hashed password. We never store your password in plain text.

Content you analyze.The images you upload, the URLs you submit (and the screenshots we capture of them), and any videos you analyze. We store the resulting heatmaps, scores and area-of-interest data so you can revisit your reports. If you import your ads' results (a CSV from Meta Ads Manager or Google Ads), we keep each ad's name, impressions, clicks, spend and conversions with its report, to compare them with the scores.

Usage data. Basic technical logs needed to operate and secure the service.

People-test participants. When someone takes a People test from a link you share, we store only their click positions and timing (in the 5-second test: the brand they pick, the few words they type and how long they took), their screen size and their device type (mobile or desktop) — no names, e-mails or IP addresses. If they came through the panel link of a workspace (one link that offers the tests the team chose for it, one after another), we also note that the answer came that way.

Clients who review. When a client opens an approval link you share, we store the name and note they give with their decision, any notes they pin on the image, and the time the link was first and last opened in a browser. No e-mails or IP addresses are stored.

How we use it

To provide the analysis you request, to save your reports to your workspace, to authenticate you, and to maintain and improve the service. We do not sell your data, and we do not use your uploaded creatives to train third-party models.

AI processing

Attention prediction runs on our own engine, on VALUE's AI server in our office in Greece. AI design recommendations (the fix-list) and the names given to detected elements are generated on that same server, by AI models that run there. If it can't answer, that request (the image, its heatmap and the analysis data) is sent to Anthropic (Claude) instead, solely to generate the response; it is not used to train models.

For the Goal Score, a copy of the analysed screen with its elements outlined and numbered is sent to Anthropic (Claude), which labels what each element is (a button, a headline, a price and so on). If Anthropic can't answer, our own server labels them instead. The copy is used solely to label the elements and is not used to train models.

Who processes your data

  • Railway (EU region) hosts the app and its database: your account, workspaces and analyses, including the images.
  • VALUE's AI server (our office, Greece) runs the attention engine, the AI recommendations and the element names, and labels the Goal Score elements when Anthropic can't.
  • Anthropic labels the Goal Score elements, and answers AI recommendations and element names only when our server can't, as described above.
  • Resend delivers the app's emails (comment and mention notifications, client review decisions, monitor reports). It receives the recipient's address and the email's content.
  • Google, only if you choose to sign in with Google: it confirms who you are, and we keep the email address, name and Google account ID it shares.
  • Integrations you set up yourself (webhooks, or an AI assistant you connect, such as Claude) receive the analysis data you send them.

Cookies

We use a single essential cookie to keep you signed in. We don't use advertising or third-party tracking cookies. Some preferences (such as sidebar state) are stored locally in your browser.

Storage & retention

Data is stored on our infrastructure provider (Railway, EU region) and retained while your account is active. You can delete individual analyses at any time: a deleted analysis can be restored for 30 days and is then removed for good. You can request deletion of your account and associated data by contacting us.

Your rights

Subject to applicable law (including the GDPR), you may request access to, correction of, or deletion of your personal data, and you may object to or restrict certain processing. To exercise these rights, contact us at the address below.
