What StumpVision is
StumpVision is a cricket scoring app that runs primarily in your browser. Most data never leaves your device.
Data stored on your device
The app uses localStorage to keep match data, backups, and preferences on your device. This data stays in your browser and is not shared with us automatically.
Data sent to the server
Data is sent to the server only when you use these features:
- Save a match — the match scorecard is sent to the server so it can be loaded on other devices or shared as a summary link.
- Live sharing — while live sharing is active, the current match state is sent to the server every few seconds so spectators can follow along. It stops when you end live sharing.
- Push notifications — if you subscribe to follow a live match, your browser's push endpoint is stored on the server to deliver score updates.
- Player accounts — if a player account is created for you by an administrator, the server stores your name, a player code, an optional email address (as a lowercase hash for deduplication), and a hashed password. Plain-text passwords are never stored.
Cookies
The app only sets a session cookie (svp_ followed by a code that is unique to this site) when you log in to a player account. It is HttpOnly, SameSite=Strict, and expires after 30 days or when you log out. No tracking or advertising cookies are used.
Third parties
StumpVision loads no external scripts, fonts, images, or analytics at runtime. There are no advertisements and no third-party tracking.
Error reports
If the site owner turns error reports on, your browser may send a short note when something goes wrong in the app: the error message, the name of the script file, the page address without anything after the question mark, and the app build. It never includes match scores, player or team details, or anything stored on your device. These notes are kept for 14 days so the owner can fix problems. Reports are off unless the owner switches them on.
If the site owner turns email on, StumpVision can send account and league messages (such as an invitation or a password reset) to the address you gave. Message text is deleted once a message is sent or fails, and a short log (time, type and a partly hidden address) is kept for 90 days.
Data retention
Match data on the server is retained until an administrator deletes it or you delete the match from the app. Player accounts are retained until an administrator removes them. Push subscriptions are removed when you unsubscribe or when your browser rejects deliveries.
Your rights
You can delete match data you saved by using the Delete option in the app. Contact the administrator of this installation to request deletion of a player account or any other server-side data about you.
