Acastus Sidekick privacy policy
Draft for review — effective date to be set when the extension is published.
What Sidekick is
Acastus Sidekick is a browser extension that lets you chat with Iris, the Acastus AI model, from your browser's side panel. Iris runs on Acastus servers operated by Astrix. Nothing runs or is downloaded to your computer apart from the extension itself.
What is sent to Acastus, and when
| Data | When | Why |
|---|---|---|
| What you type | Every message | So Iris can answer. |
| The page's address, title and visible text (up to about 3,000 characters), the names of its buttons, links and fields, and text you selected | Only in Page or Guide mode, when you send a message | So Iris can answer about the page. |
| A screenshot of the visible tab, reduced in size | Only when you take one, or with each message while live vision is on | So Iris can see what you see. |
| A session token, and a device name such as "Acastus Sidekick · Chrome" | With every request | To keep your account, chats and usage limits. |
Sidekick never reads the contents of password, payment, card, one-time-code or hidden fields, never reads what you type into form fields or text editors, and never runs in the background without your action. It does not read your browsing history, other tabs, cookies or saved passwords.
Where it goes
Requests go over HTTPS to astrixz.com, which relays them to the Acastus server. The relay provider (Netlify) handles the encrypted connection to astrixz.com and can technically see the traffic it relays. No data is sold or shared with advertisers, and it isn't sent to any other AI company.
What is stored, and for how long
- Chats are stored on the Acastus server with your account, like chats on astrixz.com/ai, so you can see your history.
- Page text is used for one reply and is not stored with the chat.
- Screenshots are deleted from the server as soon as the reply is finished, unless you turn on "Keep screenshots with chats".
- Usage records (amounts, not content) are kept to apply the 3-hour and weekly limits.
- In your browser Sidekick keeps only its session token, your settings, and which chat is open.
Your choices
- Choose Chat mode to send only your words; take screenshots or turn on live vision only when you want to.
- Sign out (Settings) removes this browser's session from the server.
- Clear Sidekick data in this browser (Settings) signs out and deletes everything Sidekick stored locally.
- Uninstalling the extension removes its local data. To ask for your chats on the server to be deleted, contact Astrix support.
Permissions the extension asks for
- Side panel — to show Sidekick next to the page.
- Active tab — to see the tab you are on, only after you click Sidekick's toolbar button (or its shortcut) there.
- Scripting — to read the page you chose, when you ask.
- Storage — for your session and settings.
- Optional: all sites — only if you turn on "Allow on every tab"; you can turn it off at any time.
Children
Sidekick isn't directed at children under 13.
