Privacy policy

Last updated November 11, 2026

Bonk is a website blocker for Chrome. It's built to know as little about you as possible. There's no account to sign up for, and your lists and browsing never leave your browser.

What stays in your browser

Everything you set up in Bonk is stored by Chrome on your own computer. That includes your blocked sites, schedules, limits, settings, stats and focus streaks. We never receive any of it.

To block sites, Bonk looks at the address of each page you open and compares it with your lists. That happens inside your browser, and the addresses are never sent anywhere.

If you remove Bonk, Chrome deletes this data. A backup file you saved stays wherever you saved it.

What Bonk sends to our server

Once a day, Bonk contacts our small server for two things:

• Feature updates. Bonk downloads a short settings file that can make Pro features free for everyone. Nothing about you is sent.
• Your Pro key, if you bought Pro. Bonk sends the key so the server can confirm your plan is still active. With it, Bonk sends a random ID it made for this copy of Bonk, and the kind of system it's on (Windows, Mac, ChromeOS or Linux). That's how a key is limited to 5 devices. The ID is made up when Bonk first needs it and isn't linked to your computer, your name or anything you browse.

Like any website, our server and its host, Vercel, see the internet address a request comes from, and may keep it in short-lived logs. We don't use it to track you.

Site icons

To show the icon next to each site on your lists, Bonk asks Google's icon service for it. That sends the site's domain to Google, but nothing else about you. Bonk only does this for sites you've added yourself.

Buying Pro

Payments are handled by Stripe. Stripe collects your payment details, email address and billing address, and works out any sales tax. We never see your card number.

Your Pro key is linked to your Stripe customer record, which is how the server checks your plan. We don't keep a separate database of customers.

The devices using your key are stored on that same Stripe record: each device's random ID, its kind of system, the date it was added and the date it last checked in. You can see them, and remove any of them, in the Bonk Pro section of Bonk's settings. A device that hasn't checked in for 60 days is removed automatically.

If you ask us to send your key to your email, we look up your purchase in Stripe by that address and send the key to it.

Stripe's own privacy policy covers what it does with your details: stripe.com/privacy.
