Version history

Do not supply account information or email. Do not send personal or sensitive information. Your support message is sent to Atmostropic only when you click “Send message”. Atmostropic checks for replies at application startup when this browser has a case secret and is online, and when you click “Check for replies”.

Atmostropic is hosted by a third-party hosting service, which logs connection information, including IP addresses.

Your conversations expire from the active support service 90 days after the last message. A randomly generated case secret identifies your conversation, and a copy stays in this browser. Clearing site data loses access, with no recovery. You can delete your conversation below.

Deleting a conversation removes it from the active support service. Copies may remain in DreamHost’s backups. DreamHost does not provide a guaranteed maximum retention period for those copies. No account or identity details are required, but your message contents and hosting connection information can identify you.

When enabled, the server emails the owner a new-message notice and a public case ID after your message is saved. The email contains no message text, access secret or identifying details supplied by you. Email delivery metadata and the notice may be retained by mail providers independently of chat deletion or expiry. Replies remain in this app; email is not a contact or recovery route.

Delete this conversation from the active support store? This cannot be undone.

Message to Atmostropic

Only your message and a case secret are sent to Atmostropic. No calculator data or diagnostic data are attached.
