Privacy policy

Last updated 2 November 2026

Alias Autofill is a browser extension that makes a new email alias for the website you're on and fills it in, along with made-up names and locations if you want them. The aliases come from a service you pick and sign in to yourself: addy.io, SimpleLogin, or your own mail server.

The developer receives nothing. The extension has no analytics, no tracking, no ads and no server of its own. Nothing is sent to the developer.

What the extension reads on web pages

Form boxes on the pages you visit (email, name, address and code boxes), only to know where to place its button.
With your own mail server only: page text like "check your email", so it knows to wait for a sign-in code.

What it reads on a page stays in your browser and is never sent anywhere.

What it sends, and to whom

Only to the service you connected, and only when you use it:

The website's name, taken from the address bar (for example netflix.com), when you make or reuse an alias, so the alias can be labelled with the site it is for.
The note on a new alias (by default the site and the date; you can change or turn off the note).
With your own mail server: a made-up name and location kept with an alias, if you turn that on, and requests for sign-in codes or confirmation links sent to that site's aliases in the last hour.
When you connect, and every few days after: a plain request for the service's home page, web app manifest and icon, to show its name, icon and colour. Nothing about you or your browsing is in that request.

Your use of addy.io, SimpleLogin or your own server is covered by that service's own privacy policy.

What it keeps in your browser

Your connection key or API key for the service you picked.
Your settings, and your own location if you choose to enter one.
Which alias you used on which site, and the made-up name and location kept with it (for addy.io and SimpleLogin).

"Disconnect" in the settings deletes the key and the site list. Removing the extension deletes everything it stored.

What websites see

Only what you choose to fill into their forms: the alias, and a name or location if you fill those in.

Permissions

Permission	Why
Storage	Keeps your settings, your key, and which alias was used on which site.
Context menus	"New address for this site" and "Fill a made-up name" when you right-click a box.
Scripting	On your own mail server only: puts the connect script into the one connect tab the extension opened.
Access to websites	The button has to appear in email boxes on whatever site you sign up on. It only reads form boxes.
Access to your service (asked when you connect)	To call your alias service's API and read its name, icon and colour.

This website

aliasautofill.com has no cookies, no scripts, no analytics and no outside resources. Like any web server, it briefly handles your IP address to send you the page; it doesn't keep access logs.

Changes

If this policy changes, the new version will be on this page with a new date.
