What Shift Picker collects, and what it never touches.

Last updated 9 September 2026. This covers the Shift Picker Chrome extension and the Shift Picker bookmark for phones and tablets.

What is sent to our server

Three things, and nothing else:

• Your activation code — the code you were given when you bought Shift Picker. It is how we know your access is valid and which version you bought.
• A random identifier created on your device the first time you use it. It is a freshly generated random value with no connection to your hardware, your name, or your Amazon account. We never store it as-is — our server keeps only a one-way cryptographic hash of it, so the stored value cannot be turned back into your identifier.
• A short technical diagnostic about how the extension itself performed: how many times it checked, which of your purchased shift times it was watching for, whether a shift was available, whether it attempted a claim, and whether that claim succeeded or was refused. This exists so that when someone says "it didn't work", there is something to look at. Numbers inside recorded request details are replaced with # before sending.
  Because a refusal is only useful if we can see the reason, this diagnostic can include a short excerpt of A to Z's own error text — the site's reply to us, not anything you typed, and never your password, session or multi-factor code.

That is the complete list. There is no analytics service, no advertising network, no tracking pixel, and no third party of any kind receiving your data.

What is never collected

• Passwords, login sessions, cookies, or multi-factor authentication codes.
• Your Amazon employee ID, alias, or name.
• Your browsing history, or anything at all from any website other than A to Z.
• Your location.
• Your schedule. We never learn which shifts you actually hold — claims happen directly between your own browser and Amazon.
• Payment or financial information. Shift Picker takes no payment; it is unlocked with a code.

What stays on your device

Your activation code, the random identifier, and a copy of the requests A to Z's own page makes are stored locally in your browser so the tool does not have to ask you again. You can erase all of it at any time by removing the extension, or by clearing your browser's data for the site.

Which sites it runs on

The extension runs only on atoz.amazon.work and atoz-apps.amazon.work. It cannot run on any other website — the browser enforces this, not just our code.

Why the permissions are what they are

• Storage — to remember your activation code so you only enter it once.
• Access to A to Z pages — the tool has to run inside the shift page to read what has been posted and press the button. Amazon rejects any attempt to do this from outside your signed-in browser, which is exactly why it works this way.
• Access to our own server — to check that your access code is still valid.

The extension deliberately does not request permission to read cookies, to see your tabs or browsing history, or to run on other sites.

How long it is kept

Your code, the hashed identifier and the most recent diagnostic are kept while your access is active, so support questions can be answered. Ask us to delete your record and we will remove it; that also ends your access, because the record is what grants it.

Sharing

Nothing is sold, rented, or shared. The only place data goes is our own server, which exists solely to check activation codes.
