Privacy
wowfah works without an account. This page explains what is stored if you choose to sign in or create alerts.
If you just browse
Two things are kept in your own browser: the auction house you last looked at (a cookie called house) and your starred items. Neither is linked to you. The web server keeps standard access logs.
If you sign in with Discord
Discord tells wowfah three things: your Discord ID, your username and display name, and your avatar. wowfah does not see your email address, your servers, your messages or your friends. A sign-in cookie called wf_session keeps you signed in for 90 days.
Your watchlist is then saved to your account so it follows you between devices.
If Discord's sign-in screen says wowfah can "join servers for you", signing in also adds you to the wowfah Discord server. You can leave it at any time and stay signed in here.
If you create Discord alerts
wowfah stores the webhook address you paste and the alerts you set on it, and uses the address only to post those alerts. Deleting the webhook in Discord stops all of them.
What is never done
Your data is not sold or shared, and it is not used for advertising.
Deleting your data
Open your account and choose "Delete my account and data". That removes your account, sign-in sessions and watchlist straight away. Remove alerts on the alerts page, or delete the webhook in Discord.

Questions about your data can be sent through the wowfah Discord server.
