Privacy Policy

Anonymous Traffic Data

We use Vercel Analytics to understand how many people visit SheetShow, where they come from, and what devices they use. This uses no cookies, stores no personal data, and cannot identify individual visitors. It's GDPR-compliant by design.

Anonymous Usage Events

When you use SheetShow, we log anonymous events like “an analysis was run” or “a dashboard was classified as operational.” These events help us understand which features are useful and how to improve the product. We track:

• What type of artifact was analyzed (dashboard, slide, etc.)
• Which analysis mode was used
• Whether the redesign section was opened
• General performance metrics (response time, token usage)
• An anonymous browser identifier so we can count repeat usage without knowing who you are

We do NOT track: your name, email, IP address, or any content from your uploaded images. Your access code is stored as an irreversible hash — we couldn't recover it even if we wanted to.

Your Uploaded Images

When you upload a dashboard, slide, or report, it is sent to Google Vertex AI for analysis. SheetShow does NOT store your uploaded images. Once the analysis is complete, the image exists only in your browser session. We have no access to your files after processing.

We use Google Vertex AI with zero data retention, meaning Google does not store or use your data to train models. If your image contains sensitive business data, consider redacting confidential values before uploading.

Screenshots

When you click “SheetShow this Page,” the extension captures a screenshot of the visible browser tab. This screenshot is sent directly to our analysis API (sheetshow.ai) for processing. It is NOT stored on our servers — once the analysis is complete, the image exists only in your browser. The screenshot never leaves the analysis request pipeline.

Data Stored Locally

The extension stores the following in chrome.storage.local (your browser, never sent to any server):

• An anonymous install identifier used only for analytics deduplication
• Your access code (for automatic authentication)
• Analysis mode preference (Microwave or Slow Cook)
• Tone preference (Dutch or British)

You can clear all stored data by clicking “Sign out” in the extension popup or removing the extension.

Anonymous Usage Events

The extension sends the same anonymous usage events as the website (analysis started, analysis complete, etc.) tagged with source “chrome_extension” and the domain of the page you analyzed (e.g., lookerstudio.google.com). These events also include an anonymous install identifier so we can measure repeat use without identifying you. No personal data, IP address, or page content is included in these events.

Permissions Explained

• activeTab — Capture a screenshot of the current tab when you click the analyze button. Only activates on your explicit action.
• scripting — Inject the analysis overlay UI onto supported pages so results appear inline on the page.
• storage — Save your access code and preferences locally in your browser.
• Host permissions — Limited to specific supported domains (Looker Studio, Power BI, Tableau, Google Slides, PowerPoint Online) so the content script only runs where it's needed.
