Student data privacy agreements

We’re a member of the A4L Student Data Privacy Consortium. We sign data privacy agreements with the districts we work with. You can read two of them below.

We’ve signed others too. Those are kept in districts’ own systems and aren’t public.

Two easy ways to sign a DPA with us

  1. Join our existing terms. Usually the fastest. We email you our General Offer (Exhibit E). Sign it and send it back, as Kent City did above.
  2. Or use your district’s own DPA. Send it to us, and we review and sign it.

Email privacy@alps.2sigma.us to start.

Who builds Alps

Alps is built by 2Sigma School, named for Bloom’s 2 Sigma Problem. We taught computer science ourselves, and wanted that mastery for every student in a full classroom. Our research and development has been supported by the Institute of Education Sciences (IES) at the U.S. Department of Education.
