Privacy Policy

Last updated: October 28, 2026

In short: We keep only what we need to run your account. Most apps don't save your questions at all. StudyXplainr saves students' questions and answers so a linked parent can see them. Nothing you submit is used to train any AI, and we never sell or give away your information. We share it only with the services that run XplainrHub, as listed in section 4.

1. What we collect

2. What each app saves

3. How AI processing works

To create answers, we send what you submit to Anthropic's Claude API. Under Anthropic's commercial terms, content sent through the API is not used to train their models. Some answers (for example in SEOXplainr) also use web search to check current information. Your account details are not sent with web searches.

4. Who we share information with

We never sell your information or use it for advertising. We share it only with the service providers that run XplainrHub, and only as needed:

We may also disclose information if the law requires it.

5. Students and parents (StudyXplainr)

6. Keeping and deleting information

We keep account information while your account is open. You can delete PlanListGo checklists and StudyXplainr history in the apps. To delete your whole account and everything saved with it, contact us at xplainrhub@pm.me.

7. Security

Connections to XplainrHub are encrypted, saved data is protected so that only your account (and, for StudyXplainr, a linked parent) can see it, and AI prompts and keys stay on our servers. No system is perfectly secure, so please don't submit passwords, account numbers or Social Security numbers.

8. Changes

If we change this policy, we'll update the date at the top. If a change is significant, we'll let you know in the apps where reasonable.
