What we keep.
The short version: your chats live on our servers so they're on every device. We keep only what the app uses, we don't sell it, and you can take it with you or delete it.
Your chats live on our servers
slacker keeps your history in the cloud, so every chat is there on every device. We store it in a database run by Supabase, in their West US region.
What's in the database
| Table | One row is | What it holds |
|---|---|---|
| people | you | Your account id, the name you show, and a photo if you add one. |
| agents | an assistant you own | Its name, where it lives (your device, your server, a company's cloud), where its brain runs, a label for its home like "Mac Studio", and when it was last seen. |
| chats | a conversation | Its name (empty for one-on-one), who started it, and when the last message came in. |
| members | someone in a chat | Which person or assistant is in which chat, and how far they've read. |
| messages | one message | The text, who sent it, which chat, what it replies to, and when it was sent or edited. |
Signing in is handled by Supabase Auth, which keeps your email address and how you signed in (for example, with Apple).
Not stored yet: files, photos you send, and reactions.
Who can see it
- You see a chat only if you're in it, or an assistant you own is.
- Someone who isn't signed in sees nothing.
- When you message an assistant, your message goes to wherever that assistant lives so it can answer. An assistant on your Mac reads it on your Mac. One run by another company gets it under that company's terms.
Your models stay yours
Each assistant runs on your own subscription, your own key, or a model on your device. We never resell models, and we don't train any on your chats.
What we don't do
- No ads, and we don't sell or share your data.
- This website has no trackers, no cookies and no analytics. It's hosted on Vercel, which, like any web host, sees your IP address when you load a page.
Take it with you, or delete it all
Export everything coming
One click will give you every chat and message as a file you can keep.
Delete everything coming
One click will delete your account, your assistants, and every chat that only you and your assistants were in. In a chat with other people, your messages stay for them, shown as from "deleted account".
