Privacy policy

Patchhall keeps as little about you as it can. This page lists everything the forum itself stores and every outside service involved.

What we store

• Your account: username, display name, an optional bio, and your password as a one-way (Argon2) hash. The password itself is never stored.
• Your e-mail address, used only to confirm your account, reset your password and send the few account mails you have not opted out of. It is never shown publicly or shared.
• What you post: topics, replies, edits (with their history), likes, bookmarks, follows and reports.
• Your IP address is used only for rate limits on sign-in, sign-up and password reset. It is stored as a salted, irreversible hash that is deleted after one day; the raw address is never stored or logged.
• Visit statistics, kept on our own server: which page was opened, the referring site, browser, operating system and device type (derived from the user agent, which is then discarded), language, time zone, screen width, and how long the page was looked at. Visitors are counted with a hash of IP address and browser that changes every day, so a visit cannot be linked to you or to your visits on other days. Signed-in staff are not counted. Kept for up to 400 days.
• No device fingerprints, location, full user agents, mouse movements or keystrokes are recorded.

Cookies

• A session cookie keeps you signed in (HttpOnly, up to 30 days, removed when you sign out).
• A theme cookie remembers light or dark mode if you choose one.
• No advertising, tracking or analytics cookies are used. A random id for the current browser tab is kept in session storage to group the pages of one visit; it is gone when the tab is closed.

Outside services

• E-mail is delivered through a mail provider (such as Resend or Brevo), which receives your address and the message in order to deliver it.
• Sign-in, sign-up and password reset may show Cloudflare Turnstile, an "are you human" check. Cloudflare processes your IP address and browser signals for that check under its own privacy policy.
• Analytics: our own, on our own server (see above). There is no third-party analytics, tracking pixel or advertising.

How long we keep it

• Account data and posts: while your account exists.
• Rate-limit records: one day. Sessions: until you sign out or after 30 days.
• Database backups: rolling copies kept for about two weeks, after which deleted data is gone from them too.

Deletion and other requests

To have your account deleted, get a copy of your data or correct it, write to the address on the contact page from the e-mail address of your account. We answer within 30 days.
