Your storage, your choice
Thundershits is a novelty for entertainment, not a medical tracker. Use it without an account in browser-only mode, or choose ChatGPT sign-in for account storage.
Browser-only mode
Dates, times, selected types, optional colour and pain choices, and entry IDs stay in local storage in this browser profile. Entries and imported CSV contents are not uploaded in this mode. Up to 100 recent entries are retained; export a CSV to keep a longer history.
Account mode
After you choose account mode and sign in with ChatGPT, saved entries are sent to this site’s server-side database and associated with your site-specific account ID. The server checks ownership on reads, saves and deletions. Sign in to the same account on another device and choose account mode to see that history. This is site storage, not a ChatGPT conversation.
The site receives your signed-in identity to identify your account and display your name. Account entries contain an entry ID, date and time, selected type, and optional colour and pain choices. The interface displays up to 1,000 account entries.
Optional observations
Colour and pain default to “Not recorded” for every new entry. Opening either control shows a medical-device reminder. These choices are stored with the entry in your selected storage mode and included in CSV exports. Older entries and older CSVs have no colour or pain recorded.
Switching modes
Browser and account histories remain separate. Signing in does not automatically upload existing browser entries. The “Copy browser entries to account” action asks before uploading and leaves local copies intact. Switching back to browser-only mode or signing out does not delete server entries.
CSV import and export
Downloads contain the currently selected history. Browser-only imports remain local; account-mode imports ask for confirmation before sending valid entries to the server. Imports accept up to 100 new entries at a time. Downloaded files are outside the app.
Shared devices and loss of data
Anyone using the same browser profile may see local entries. Someone with your signed-in session may also see your account history. Sign out on shared devices. Clearing browser data can erase local history; it does not erase account history. Keep your own exports if you want a backup.
Hosting
The hosting service processes requests, authentication and operational information needed to run the site. Account mode sends entries to the hosted database. Browser-only mode does not send entry contents. The site has no public history feed or feature for sharing your account entries with other visitors.
Delete entries
Choose the relevant mode on the home page, then use an entry’s × button to delete it from that history. The button below deletes only this browser’s complete local history; it does not affect account entries or exported files.
