Cookies and device storage
The information PoundPost stores on your browser or phone, why it is there and how to remove it.
Updated 7 September 2026
Sign-in cookies
The website uses Supabase sign-in cookies, with names beginning sb-, to keep your session and complete sign-in. The current library sets a maximum cookie lifetime of 400 days, refreshed as the session changes. Your session can end earlier. Signing out removes the current browser’s sign-in cookies. Blocking them prevents sign-in from working.
Remembering your choices
Browser storage remembers your theme in pp-theme and up to five recent places in pp.places. These stay until replaced or you clear site data. They let the site reopen with your chosen appearance and location.
Drafts and payment retries
pp:composer-draft stores an unfinished post in your browser and discards it when next read after 14 days. Temporary payment references help retries avoid duplicate charges and are cleared when the action settles. pp:message-attempt stores messages awaiting delivery confirmation, including their text, offer amounts, account and conversation identifiers, reply references and photo metadata. These records are cleared after confirmed delivery, sign-out or accepted account closure. If automatic cleanup fails, clear this browser’s site data. pp:message-epoch stores an account identifier and an opaque version to retire older tabs; it remains until site data is cleared. Message recovery records contain no passwords or authentication tokens. Clearing site data can remove unfinished work.
Offline files and phone storage
The website can cache its offline page, fonts and icons. It does not cache private conversation or account pages for offline use. The phone app stores sign-in credentials in device secure storage. Notification permission and delivery subscriptions are also stored by your browser or phone.
Payment, maps and security services
Payment fields, map requests and any enabled anti-abuse checks connect to their providers when you use those features. Those providers can receive device and connection information and may use their own storage. Their privacy information is linked below.
Your controls
Use your browser’s site settings to inspect or clear cookies, storage and notification permission for PoundPost. On a phone, use the app’s Settings and your device settings. Clearing local storage does not delete information held in your PoundPost account. Use Account deletion for the account closure options.
