Controller

Understand This Page is provided by Finnzon Oy, Business ID 2849466-3, c/o Jussi Hyvärinen, Ankkurinvarsi 17, 02320 Espoo, Finland.

Finnzon Oy is the data controller for the service data it receives, including anonymous install IDs, usage counters, plan status, Pro subscription entitlement metadata, customer email addresses used for billing, and support requests.

Privacy contact: info@finnzon.com.

Overview

Understand This Page is a Chrome extension by Finnzon Oy that analyzes the current page after you explicitly ask it to.

The extension is designed without user accounts, analytics, browser history sync, hidden page reading, or automatic page uploads. The built-in AI service uses a Finnzon-operated proxy to forward user-requested analysis to OpenAI.

Information processed

When you run an analysis, the extension may process the current page URL, title, canonical URL, metadata, selected text, surrounding text, headings, readable page text, tables, links, image metadata, code blocks, transcripts, and page-type-specific signals such as product, job, restaurant, news, documentation, research, GitHub, search, or email context.

For Gmail pages, the extension can analyze visible message content, visible labels, links, attachment signals, sender information, recipients, timestamps, and collapsed-message signals that are present in the visible page context.

Local storage

Your answer language, default task, context depth, privacy acknowledgment, cache preference, optional personal profile fields, local usage estimates, and cached answers are stored in Chrome extension storage on your device.

The extension also stores an anonymous per-install identifier locally. Finnzon uses it only to meter built-in service quotas and subscription entitlements.

Answer caching is local and optional. Email analysis is excluded from persistent answer caching.

AI processing

Page content is not analyzed automatically. When you click analyze and have acknowledged the privacy notice, only the prompt and captured context needed for the requested analysis are sent for AI processing. If you have filled in the optional profile fields, their content is included in the request to personalize the answer.

The request is sent to Finnzon's proxy, which forwards it to OpenAI with Finnzon's server-side API key. OpenAI receives the submitted prompt and captured page context for AI processing and may process that data outside the EU under its applicable data processing terms.

Finnzon records quota counters, plan status, request kind, model, token counts, upstream status, and estimated cost data, but does not store captured page content or generated answers on its server.

Payments and subscriptions

Paid Understand This Page plans are processed by Stripe. Stripe may process checkout, subscription, invoice, payment method, tax, billing, and customer portal information according to Stripe's terms and privacy policy.

Finnzon stores subscription entitlement metadata such as product, plan, status, Stripe customer or subscription identifiers, billing period, customer email, and anonymous install ID so the extension can receive the correct quota.

Service providers

Finnzon uses hosting and database providers to run the website, license server, proxy, quota counters, and admin tools. These providers process service data as infrastructure processors.

Stripe processes payment and subscription data. Stripe may also act as an independent controller for fraud prevention, legal compliance, and payment network obligations.

OpenAI processes the page context and prompts sent when you explicitly request an analysis.

Retention

Local settings, cached answers, and the anonymous install ID remain in Chrome storage until you remove the extension or clear extension data.

Finnzon retains quota, entitlement, request-log, billing, and support data for as long as needed to provide the service, prevent abuse, troubleshoot issues, meet accounting or legal obligations, and maintain subscription records.

Captured page content and generated answers are not stored by Finnzon on its server.

What Finnzon does not collect

The extension does not create Finnzon user accounts, does not add analytics, does not sync browser history, and does not send page content before a user action.

Finnzon does not store captured page content, selected text, cached answers, or follow-up conversations on its server.

The extension does not perform mailbox actions. It does not send, draft, archive, label, delete, or otherwise modify your email.

Chrome permissions

The extension uses Manifest V3 permissions for active-tab access, script injection after user action, clipboard writes, local storage, context menus, the offscreen document used for clipboard support, and the Chrome side panel.

Network access is used to send the analysis request to Finnzon's proxy.

Your controls

You can avoid analyzing sensitive pages, disable local answer caching, remove the extension, or clear Chrome extension storage to delete locally stored settings and cached data.

You may contact Finnzon to request access, correction, deletion, restriction, objection, or portability where applicable under data protection law.
