The three domains

TeachSmartHQ™ runs on three hostnames. Allowlisting all three, over HTTPS on port 443, is sufficient for full functionality.

What happens on the student endpoint

play.teachsmarthq.com serves practice activities a teacher has already created and assigned.

There are no student accounts and no student sign-in. A student opens a link their teacher gives them. There is no registration, no email field, and no name field. A student who visits play.teachsmarthq.com without a class link sees a single line telling them to ask their teacher for one.

Students do not interact with an AI system on this endpoint. They open material a licensed educator generated, reviewed, and assigned.

Student data

The four statements below are the ones a district reviewer usually needs. Each was checked against the running code, not against our own marketing.

• The student surface is identity-free by design. A student is represented by a chosen icon and an opaque token, not by a name. There is no field anywhere on the student endpoint that asks a student who they are.
• What we store: teacher-created instructional content, and a limited record of practice activity used to generate progress information for the teacher — kept against an anonymous activity token, never against a student's name. We do not store grades, demographic records, or student information pulled from a district system. A teacher may upload a student's own paperwork herself; personal details are stripped on the way in, and she chooses what is kept.
• Personally identifying text is scrubbed server-side before it reaches an AI provider, and the scrubber is fail-closed: if it cannot complete, the request is dropped rather than forwarded unscrubbed.
• Our AI provider is contractually prohibited from training on our customers' inputs or outputs. The provider is Anthropic; the restriction is in their commercial terms.

Is this an AI tool?

Yes, on the teacher side, and we'd rather say so plainly than have you find out from a filter.

Educators use TeachSmartHQ™ to generate worksheets, lesson plans, and documentation drafts. That generation is AI-assisted and it happens on app.teachsmarthq.com, behind an authenticated staff login.

Some filters categorize us under a general "Artificial Intelligence" bucket on that basis. If your district blocks that category on student devices, we'd note that play.teachsmarthq.com — the only hostname students use — has no accounts, no sign-in, and no student-facing AI interaction. It serves material a teacher already made.

Current categorizations

Lightspeed Systems — reachable on student devices, all three hostnames, verified September 22, 2026.

Lightspeed initially classified TeachSmartHQ™ under Artificial Intelligence. We asked them to look again. Their content quality team reviewed the actual product — where the AI generation happens, and what a student’s device actually touches — and moved us to a category their end users are permitted to reach. In their words, the AI category was “too strict in this case.”

We verified it the only way that counts: all three hostnames were opened on a filtered student Chromebook in a Lightspeed district and all three loaded. Any district can repeat that check.

We’re leading with this one because it’s the review we’re proudest of. We did not ask them to overlook that we’re an AI-assisted tool. We asked them to look at where the AI sits. It sits behind a staff login.

If your filter reads us differently, we’d like to know — email us and we’ll submit a correction. It works: the row at the top of this table used to say something else.

This list covers the vendors we have verified directly. It is not every filter in use. If yours isn't here, contact us and we'll submit.

Listed but not reportable — we name this rather than leave it out, so a reader can tell “there is nothing to report” apart from “we didn’t look”:

• Norton — Norton's consumer products do categorize websites, but Norton publishes no owner-facing way to look up or confirm a site's category. A site owner can see and dispute a safety rating; there is no equivalent for a category. We have nothing to report here that you could independently check, so we do not list one.

Questions

Email hello@teachsmarthq.com and a human will answer. If you need a Data Privacy Agreement, an NDPA, or a security review for vendor approval, say so and we'll start that conversation.
