Your listings stay on your device
Everything you type into A9 Lister — your ads, listings, leads, comps and profile — is saved in this browser on this device. It is never sent to Atlas9 or anyone else. We can't see it, and we couldn't hand it over if we were asked.
Because it lives only in your browser, clearing your browser data erases it. Use Profile → Save backup file to keep a copy, and Restore from file to bring it back or move it to another device.
What Atlas9 does count
To improve the tool, we count two things, and neither includes anything you wrote:
- Anonymous button events. When you copy an ad, save a listing, mark one posted, log a lead and so on, the page sends the name of that action and the ad category (for example "copy_ad" and "apartment"). No ad text, names, phone numbers, emails or IP addresses are stored.
- Page views, through Cloudflare Web Analytics. It does not use cookies and does not track you across other sites.
What we don't do
- No accounts and no sign-in.
- No cookies.
- No selling, renting or sharing data. There is no personal data on our side to sell.
- No ads and no ad trackers.
Posting your ad
A9 Lister doesn't post for you and never logs in to any listing site. You copy your ad and post it yourself. The search and posting links open those sites in a new tab, and their own privacy policies apply there. A9 Lister is not affiliated with craigslist.
