Privacy Policy

Last updated: November 15, 2026

Our Core Privacy Principle: Client-Side Processing

Unlike traditional web tools websites that upload your files, passwords, and sensitive text to remote servers, Vesso runs the vast majority of utilities 100% locally inside your web browser using modern HTML5 Canvas, Web Cryptography, and WebAssembly APIs. Your private data never leaves your device.

1. Information We Do Not Collect

We do not store or transmit any text entered into our converters, formatters, or counters.
We do not upload or store your images or PDF documents on any server.
We do not log passwords, UUIDs, or hashes generated by our cryptographic utilities.
We do not require user accounts, emails, or phone numbers to use our free utilities.

2. Browser Local Storage

When you bookmark a tool as a favorite or access recent utilities, we save those preference identifiers strictly inside your browser's local storage (localStorage). This data is completely private to your device and is never synchronized to our servers.

3. First-Party Usage Analytics

We record limited, aggregate usage statistics in our own database to understand which pages and tools are useful. This includes page paths, tool opens, favorites, shares, broad device categories, and referring website hostnames. We do not use analytics cookies or store IP addresses, browser fingerprints, uploaded filenames, or the contents entered into tools. Browser Do Not Track preferences are respected.

4. Server-Assisted Network Utilities

For network diagnostic utilities (such as HTTP Status Checker, Redirect Chain Checker, and SSL Certificate Inspection), our server must execute a network request to the public domain you specify. These requests:

Are strictly validated against SSRF to prevent internal network abuse.
Do not retain or log the target URL beyond the immediate ephemeral response.
Do not collect personal information about you.
