What we get from Google
You sign in with Google. With your permission, Google shares your name, email address and profile picture with us. We never see your Google password, and we can't read anything else in your Google account or post to it.
We use these to:
- create your Offseason Lab account and keep you signed in;
- show your name and picture to the people on your teams;
- match an invitation to the email address Google has verified, so you join the right team.
Offseason Lab's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
What you add
The ratings you give your own skills, the focus and plan you work on, and the sessions you log. Coaches add their ratings of your skills, feedback, and notes. Teams have a name, a roster with each person's role, and invitations, which hold the email address they were sent to.
Who can see it
- Your coaches and your team's managers see your plan, sessions and ratings, so they can coach you.
- On an open team, players see each other's focus, plans and sessions. On a closed team, players see only their own.
- Ratings are never shown to other players. A coach's notes about a player are seen only by coaches.
- A personal space is yours alone, and anyone you invite into it.
- The people who run Offseason Lab can see data when that is needed to support, fix or secure the app.
What we don't do
We don't sell your information, show ads, or share it with anyone for their own use. We don't use analytics or advertising trackers. We use your information only to run Offseason Lab.
Services we use
- Supabase stores the database and handles sign-in.
- Vercel hosts the app.
- Google provides sign-in.
They handle your information only to provide their service to us.
Cookies
We use only the cookies the app needs: one keeps you signed in, and a few small ones remember the space you last opened, your time zone, and hints you have already read. There are no advertising or analytics cookies. Google's sign-in button may set Google's own cookies, covered by Google's privacy policy.
Keeping it safe
Everything travels over HTTPS. The database checks every request against who you are and what your role allows, so the app can't show you anything you aren't allowed to see. Your sign-in cookie can't be read by scripts on the page.
Keeping and deleting your information
We keep your information while you use Offseason Lab. To delete your account and what you added, email jon1mast@gmail.com from the address you sign in with, and we will confirm within 30 days. Records that belong to a team as a whole, such as its name and the team's own plan, stay with the team.
You can also remove Offseason Lab's access to your Google account at any time in your Google account settings.
Children
Offseason Lab is not meant for children under 13, and we don't knowingly collect their information.
Changes and contact
If this policy changes, we will update this page and the date at the top. Questions or requests: jon1mast@gmail.com. Using Offseason Lab is also covered by our terms of service.
