Bloxlabs Auto extension: privacy

Last updated October 28, 2026

What it does

The Bloxlabs Auto extension uploads thumbnails you choose on Bloxlabs to your Roblox experience and manages its Home Page thumbnail A/B test (Roblox calls it Personalized thumbnails). It only acts when you click a button on a Bloxlabs page. It never runs in the background on its own.

Your Roblox login

To talk to Roblox, the extension uses the Roblox login already in your browser, the same way Creator Hub does. It never reads, stores or sends your Roblox cookie or password anywhere. Requests go straight from your browser to Roblox (apis.roblox.com and users.roblox.com).

What it shares with Bloxlabs

After you upload or change your A/B test, it tells the Bloxlabs page you're on what's now on Roblox: your Roblox user name and id, and your experience's Home Page thumbnail ids, asset ids, moderation status and which are in the test. Bloxlabs stores this with your project so your dashboard and Auto's suggestions stay up to date.

It shares nothing else, works only on bloxlabs.io pages, and doesn't track your browsing.

What it doesn't do

No ads, no analytics, no selling or transferring data to anyone, and no use of data for anything other than this feature. Bloxlabs' use of this data follows the Chrome Web Store User Data Policy, including the Limited Use requirements.

Removing it

Remove the extension from chrome://extensions at any time. To delete what Bloxlabs stores for a project, delete the project in Auto, or email jonas@bloxlabs.io.
