Is EraPin blocked at your school?

Here's everything your IT team needs to get it approved.
What is EraPin?

EraPin is a free daily history and geography classroom activity used as a bell ringer and lesson starter by teachers across the US and UK.

Students see a historical photograph, drop a pin on a map to guess the location, then estimate the year. Five rounds, five minutes, live leaderboard.

No student accounts. No logins. No app to install. Works on Chromebooks, iPads, phones, and any browser.

Privacy & Safety
What IT admins scan first — this is our promise.
  • No student accounts or logins required
  • No personally identifiable information collected from students by default — real names appear only if a teacher opts in to upload a class roster, and the school is the data controller for that data
  • No advertising of any kind
  • No social features or student-to-student interaction
  • HTTPS encrypted on all pages
  • Student scores are anonymous — identified only by a name students type themselves
  • Teacher accounts require only an email address — never a student email
  • No student data is ever sold, and none is shared with third parties for advertising or marketing. The infrastructure services we rely on (hosting, database, maps, fonts, aggregate analytics) are all listed in our privacy policy
  • Hosted on Vercel, with data stored in Supabase (US) — enterprise-grade infrastructure

All historical images are served through erapin.com — student browsers never hotlink an outside image host. And every AI feature runs on our own servers: no student or teacher browser ever connects to an AI provider.
