The short version
Nothing you put into this site is private. Treat everything you enter as public info that other students can see. I'm not responsible for anything that happens with that info. Use the site at your own risk.
Who runs this
Max Mendelson. This site is a personal side project — it's not affiliated with, endorsed by, or operated by any school or institution.
What goes in
- Your name and student ID (S#).
- Your phone number, if you choose to give one. It's optional.
- A PIN you pick. The PIN itself isn't stored — your browser hashes it (PBKDF2 / SHA‑256) before sending anything to the database.
- Any blocks you post and any notes you attach to them.
Where it goes
- Everything above is stored in a Google Firebase database I control.
- Your name, S#, any phone number you provide, and every block you post are visible to everyone else using the site. That's how the exchange works.
- Your current profile is cached in your browser so you stay signed in. Your PIN and its hash are not cached locally.
- Anti-bot protection uses Google reCAPTCHA v3, which collects standard device/browser signals to tell humans from scripts. See Google's privacy policy.
What I don't do
I don't sell your data. I don't run analytics or advertising tracking on you. The PerioMaxer link is a plain link to the App Store.
No guarantees
- No warranty of any kind. The site may go down, lose data, get scraped, or otherwise misbehave without warning.
- I'm not responsible for any harm, loss, or consequence from using this site — including but not limited to missed blocks, miscommunications, or anything involving the info you or anyone else posts here.
- Don't put anything sensitive in here. If you wouldn't write it on a whiteboard in the hallway, don't put it on this site.
- By using the site you agree to the above.
Removing your stuff
Remove any block you posted from the My Blocks tab. Sign out from the Account tab to clear the cache on a device. To delete your profile entirely, reach out to Max directly.
