XtrikeW is a free, non-commercial bowling tracker, made as a personal project. This page says plainly what the app keeps and who can see it.
In short
- Your bowling data is saved on your own device, and on the XtrikeW server only if you sign in.
- Only what you share with a Bowling Group leaves your device.
- No ads, no tracking, and your data is never sold.
What the app keeps
The games, sessions, practice, goals, centres, balls, notes, profile and photos you enter, including scores you log for other bowlers. Only add other people who are happy for you to do that.
Where it is kept
On your device, in your browser's storage. If you clear it, remove the app or lose your device, your data can be lost. Save a copy now and then with More → Data & Backup → Export Backup.
Scorecard and oil sheet scans are read on your device and are not uploaded.
Signing in with Google
Signing in is optional. If you sign in with Google, XtrikeW receives only your Google name, email address and profile picture. XtrikeW never sees your Google password.
This information is used only to create your XtrikeW account, keep your bowling data in step across your devices, and show your name and picture to members of the Bowling Groups you join. A copy of your account, your bowling data and your ball and profile photos is then kept in the XtrikeW database on Amazon Web Services, so each of your devices can bring in what you add on the others. It is not sold, not used for ads, and not shared with anyone else.
XtrikeW's use of information received from Google follows the Google API Services User Data Policy, including its Limited Use requirements.
Bowling Groups
If you join a group, your name, photo, stats, goal progress, ball names and pictures, centre names, announcements and attendance are shared with its members. If you are signed in, this goes through the XtrikeW server, and only signed-in members of the group can read it. Groups that started on a Google Form and Google Sheet are copied to the server, and while some members still use the Sheet, anyone with the group's invite code can read what is on the Sheet, so only give the code to people you trust. Sessions logged for another member are encrypted so only that member can open them.
You choose which of your groups each session is shared with, or keep it to yourself; a group's rankings only count the sessions shared with it. A group's organiser can rename it, make a new invite code, remove a bowler, hand the group to someone else or end it. Anyone with a group's invite code can join it while it has room, so share the code only with people you bowl with.
Leaving a group removes you from its rankings. Deleting your account also removes what you posted to your groups on the server. The group organiser controls the group's Google Sheet, if it has one.
Removing your data
Use More → Data & Backup → Clear All Data to remove everything from a device, and leave your Bowling Group to stop sharing.
If you signed in, More → Data & Backup → Delete Account removes your account and all your data from the XtrikeW server. Clear All Data only clears this device; the copy on the server stays until you delete your account.
You can also email XtrikeW@gmail.com from the same Google address to have your account and its data deleted. You can remove XtrikeW's access at any time from your Google Account settings.
