Cookies deleted.

Hi Brave Support,

I’m experiencing a serious issue where Brave doesn’t reliably store cookies or login data across sessions, and the Cookies file is either missing entirely or gets deleted/reset periodically.

:magnifying_glass_tilted_left: Symptoms:

  • The Cookies file under User Data\Default\ is often missing, or appears temporarily and disappears again.
  • Login sessions/logged-in accounts are randomly wiped, even without clearing cookies manually.
  • Sometimes logins persist for a while, but:
    • After restarting my PC using the power button (forced shutdown),
    • Or after Windows performs automatic repairs,
    • Brave loses all stored cookies, logins, and site data.
  • I have never enabled “Clear cookies on exit” or used Guest/Incognito modes.

:test_tube: What I’ve tried:

  • Verified all settings allow cookies.
  • No such issue on Chrome or Firefox — only Brave is affected.

:desktop_computer: System:

  • Windows 11 Pro 64-bit
  • Brave version: [insert your version from brave://settings/help]
  • System SSD is healthy (no file system errors reported by Windows).

:red_question_mark:My Questions:

  • Why does Brave sometimes fail to write or preserve the Cookies file?
  • Is there any way to prevent data loss after system crashes or shutdowns?
  • Is this a known issue?

Thank you in advance,
Adrian

@Juhnz,
Are cookies being cleared for specific sites, or is it for all stored site data? You state that this happens periodically – do you know roughly how often this occurs? Additionally, you asked:

Does cookie data get deleted every time you shut down your PC?

Additionally, do you have any extensions installed? Also, can you confirm that you do not have Forget me when I close this site toggled “on” in your Shields settings?
