Privacy Policy

Rested Teacher is a service of Keypair Software LLC, a Florida single-member limited liability company. Contact: domains@keypairsoftware.com.

We collect the following categories of data:

• Account data: email address, display name, password (stored only as a salted hash by our auth provider), and your school or district name if you choose to provide it.
• Course and schedule data: the courses you teach, your meeting schedule, calendar holidays, your tenant configuration.
• Lesson and pacing data: the lesson plans the AI generates for you, your edits, your mark-taught history, your sub-plans, and any written feedback you submit through the regenerate flow.
• Billing data: billing email, subscription status, and payment-method tokens via Stripe. We do not store full credit card numbers — Stripe handles that.
• Operational data: server logs, IP address, browser user-agent, approximate location derived from IP, and timing of requests, for security and service reliability.

We do not collect student PII as a routine part of the Service. The lesson generator operates at the course and standard level — it does not need student names, identifiers, grades, or contact information to function. Please do not paste student PII into regenerate-feedback fields, inline edits, or notes. If you do, we treat it as inadvertently disclosed and will purge it on request. See Terms § 5 for the FERPA / district-policy implications.

We use your data to:

• Authenticate you and operate your account.
• Generate and serve your lesson plans and pacing.
• Process subscription billing.
• Send transactional email (verification, billing, security alerts).
• Improve the Service — debug issues, measure feature use in aggregate, refine prompts.
• Comply with legal obligations and enforce our Terms.

We do not sell or rent your personal data. We do not use your data to train external AI models — see § 5 on vendors.

We rely on the following vendors to run the Service. Each is contractually bound not to use your data for their own purposes:

• Supabase — database hosting, authentication, file storage.
• Anthropic — the underlying large-language model that powers lesson generation. Per Anthropic's commercial API terms, prompts and outputs are not used to train Anthropic's models.
• Vercel — application hosting and edge compute.
• Cloudflare — DNS, domain registrar, and email routing.
• Stripe — payment processing.

If you opt your tenant into the community lesson library, lessons that meet quality criteria may be served to other Rested Teacher users teaching the same standard. Only the lesson content is shared — your name, school, class titles, and personal notes are not. You can opt out at any time from your settings; doing so stops new lessons from entering the pool but does not retract previously-shared lessons.

We use strictly necessary cookies to keep you signed in (Supabase auth session) and to keep CSRF protections honest. We do not use third-party advertising cookies or cross-site tracking. We may use a first-party analytics tool to measure aggregate feature usage; if we do, we will name it here.

We retain account, course, and lesson data for as long as your account is active. If you delete your account, we delete or anonymize your personal data within 30 days, except where retention is required by law (e.g., financial records under U.S. tax law) or by our legitimate interest in fraud prevention. Server logs are retained for up to 90 days.

You can:

• Access your account data from within the Service or by request.
• Correct inaccurate data via your account settings or by request.
• Export your lessons in a portable format (planned; available on request in the meantime).
• Delete your account at any time.
• Object to processing or restrict it where applicable law (e.g., GDPR for EU residents) gives you those rights. Email domains@keypairsoftware.com to exercise any of the above.

The Service is for adult educators. We do not knowingly collect personal data from anyone under 13. If you believe we have inadvertently collected such data, contact us and we will delete it. We expect teachers using the Service to follow FERPA and their district's data policies, and not to enter student data into the Service.

We use industry-standard practices: TLS in transit, encryption at rest (via Supabase), row-level security so a teacher can only access their own tenant's data, password hashing (handled by our auth provider), and routine dependency vulnerability scanning. No system is perfectly secure; we will notify affected users in the event of a breach as required by applicable law.

We operate the Service from the United States. If you access it from outside the U.S., you consent to the transfer of your data to and processing in the U.S., where data protection laws may differ from those in your country.

We may update this policy from time to time. We will post the revised policy with an updated "Last updated" date and, for material changes, notify active subscribers by email.
