Tab Amp browser extension · Toybox Labs · Last updated November 3, 2026

The short version

Tab Amp processes your tab's audio entirely on your device. Your audio is never recorded, stored or transmitted anywhere. The only data the extension sends is anonymous feature-usage counts ("an install used the equalizer") and your operating system type, which cannot identify you.

Audio

To boost volume past 100% and apply the equalizer and effects, Tab Amp captures the audio of tabs you activate it on and re-plays it through your browser's audio engine, on your machine. This audio is processed in memory and immediately played back. It is never recorded, saved, analyzed or sent over the network. Tab Amp cannot see or process audio in tabs you haven't activated it on.

What we collect

• A random install identifier, generated on your device (a random UUID). It is not derived from your identity, device, accounts or browsing, and resets if you reinstall the extension.
• Feature-usage events, which feature was used (volume, equalizer, limiter or an effect) and when, at most once per feature each time the popup is opened.
• Operating system type (for example macOS, Windows or ChromeOS), sent with those events. It does not include your OS version or any device details.
• Uninstalls. If you remove Tab Amp, Chrome opens our goodbye page with that random install identifier attached, and we record that the install was removed. This tells us how many people stop using it.
• Uninstall survey answers, only if you choose to fill in the optional survey on that page: the reasons you pick and any note you write, stored with that random install identifier. Please don't include personal information in the note.

That's the complete list. Tab Amp does not collect browsing history, page content, URLs, audio, personal information or anything else, and it does not use cookies or third-party analytics SDKs.

How it's used and stored

Usage events are sent to our own endpoint (toybox-labs.vercel.app) and stored in a database hosted in the United States (Vercel / Neon). Survey answers are stored with our database provider Supabase. We use them solely to understand which features are used and which systems to support so we can improve the extension. We do not sell or share this data, use it for advertising or use it to determine creditworthiness or for any purpose unrelated to improving Tab Amp.

Your settings

Your volume, EQ and effect settings are stored locally in your browser's extension storage and never leave your device.

Donations

The optional "buy me a coffee" link opens a checkout page operated by Stripe. Any information you enter there is handled by Stripe under Stripe's privacy policy; the extension itself never sees it. These charges appear as TOYBOXLABS on your card statement.
