Privacy Policy

Effective date: March 30, 2026 Developer: Steven Trotter

This page covers the privacy policies for both products in the Vesper accessibility suite. Neither product collects, transmits, or stores any personal data.

Vesper Inspect - Chrome Extension

Overview

Vesper Inspect does not collect, store, transmit, or share any user data.

Vesper Inspect is a Chrome Extension that inspects the accessibility attributes of elements on web pages you visit. All processing happens entirely within your browser.

Data Collection

Vesper Inspect collects none of the following:

No personally identifiable information
No browsing history
No page content transmitted to any server
No analytics or usage tracking of any kind
No data sent to the developer or any third party

What the Extension Accesses

Vesper Inspect reads the following locally within your browser, solely to display it in the on-screen tooltip overlay:

HTML element attributes on the page you are currently viewing, including ARIA labels, roles, alt text, title attributes, and tabindex values
Computed styles on elements, used to display font size, weight, and family information
The URL of images on the current page, used to look up file size from the browser's performance timeline or via a direct HEAD request to the same server serving the image

Nothing is stored beyond your current browser session.

Permissions

storage

Used solely to save your tooltip mode preference (Mouse or Tab) and inspector on/off state between browser sessions. This data is stored locally on your device and is never transmitted anywhere.

activeTab

Required to inject the accessibility inspection overlay into the page you are currently viewing. The extension reads element attributes on that page and displays them locally in a tooltip. No page content leaves your browser.

Third Parties

Vesper Inspect does not integrate with, report to, or share data with any third-party service, analytics platform, advertising network, or external server.

Vesper Audit - Desktop App

Overview

Vesper Audit does not collect, store, or transmit any personal data.

Vesper Audit is a desktop application for macOS that crawls websites and generates accessibility audit reports. All auditing activity runs on your local machine using your installed copy of Chrome.

What Vesper Audit Accesses

Vesper Audit accesses the following:

The pages of the website URL you choose to audit - to run accessibility checks and collect links
Your saved settings (output folder, exclusion rules, scan options) stored in a local config file on your computer, never transmitted
Notion's API - only if you choose to enable optional Notion export and provide your own integration token

Network Requests

Vesper Audit makes outbound network requests only to:

The website you are auditing, to load pages and run accessibility checks
External URLs found during the crawl - HTTP HEAD requests only, to verify whether links are reachable
Notion's API, only if you have enabled Notion export and provided an integration token

No other outbound network requests are made. Vesper Audit does not include analytics, telemetry, crash reporting, or usage tracking of any kind.

Notion integration (optional)

If you enable Notion export, audit report data (page URLs, violation descriptions, PDF links, broken links) is sent to Notion's API using an integration token you provide. No personal data is included. Notion's own privacy policy governs how that data is handled once it reaches their servers.

Local Data Storage

Vesper Audit stores the following on your local machine only:

A config file containing your saved settings - never leaves your device unless you explicitly export it
PDF reports and JSON results files in your chosen output folder

Both Products

Children

Neither Vesper Inspect nor Vesper Audit knowingly collects any information from anyone, including children under the age of 13.

Changes to This Policy

If this privacy policy changes, the updated version will be published at this URL with a revised effective date.
