Privacy Policy

Effective Date: July 29, 2026 · Last Updated: October 26, 2026

1. Who We Are

PipePrep AI is an exam-prep app for people applying to union pipe-trades apprenticeships — plumbers, pipefitters/steamfitters, sprinkler fitters, and HVAC technicians. The app is operated by Michael Briglio / Imperium Power Systems.

PipePrep AI is an independent study tool. It is not affiliated with, endorsed by, or sponsored by the United Association (UA), GAN Human Resources, or any union, training committee, or testing organization.

2. What We Collect

Information you provide

Questions and messages you send to the AI tutor and mock-interview features
Your email address, only if you choose to enter it — during onboarding, or to get an alert when your local opens applications. We use it to send those alerts and study emails, and to attach to your subscription record so a purchase can be restored on a new device. Every email has an unsubscribe link.
Feedback you choose to send from the in-app rating prompt

Information collected automatically

Anonymous usage analytics — which features and practice modes are used, identified by a random per-install ID (not your name or email)
Website page views and app-store link clicks on pipeprepai.com — the page, a random per-browser ID, whether the device is a phone, and the referring site (domain only). No IP address, cookies or advertising IDs.
Subscription status and transaction data (managed by Apple/Google and RevenueCat)
Device type, OS version, and app version for crash reporting
A push notification token, only if you turn on alerts for a local, so we can notify you when its application window opens

What we do NOT collect

Accounts — PipePrep AI does not require an account or login, and giving an email address is optional
Location data — we do not request or store your location
Contacts — we do not access your contact list
Camera or microphone content — nothing is recorded or uploaded by us
Financial data — payment processing is handled entirely by Apple or Google

3. How We Use Your Data

To generate AI tutor responses and mock-interview feedback to your questions
To manage your subscription status
To understand which features are used so we can improve the app
To detect and fix bugs and crashes

We do not sell your data. We do not use your data for advertising. We do not share your data with third parties except as described in Section 4.

4. Third-Party Services

Anthropic

Powers the AI tutor and mock-interview scoring. Your chat messages and interview answers are sent to Anthropic's API to generate responses. Anthropic's privacy policy applies to data processed by their models.

RevenueCat

Manages subscription state across iOS and Android. Receives subscription event data from Apple and Google, and your email address if you provided one, so your subscription can be restored. RevenueCat does not receive your AI questions or practice history.

Vercel

Hosts the API proxy the app talks to. Server-side request logs are subject to Vercel's data retention policies.

Supabase

Stores anonymous usage analytics events (feature usage keyed to a random install ID — never your chat content), plus the email addresses and push tokens you choose to give us for alerts and study emails.

Resend

Delivers our emails (window alerts and study emails) to the address you provided.

Apple App Store / Google Play

Manage app distribution and in-app purchases. Purchases are subject to Apple's and Google's privacy policies respectively.

5. Data Storage & Security

Your practice data — test results, drill history, saved progress, and chat history — is stored locally on your device. It never leaves your phone except for the individual chat messages sent to our AI provider for processing.

Server-side, we store anonymous usage analytics, what is necessary for subscription management, and — only if you gave them to us — your email address and alert push token. We use HTTPS for all data in transit. We do not operate a database of user accounts — there are no accounts.

6. Data Retention

On-device data (practice results, chat history) — retained until you delete the app or clear app data
Subscription data — retained by RevenueCat per their policies
Anonymous analytics events — retained for up to 24 months
Email address and alert push token — kept until you unsubscribe, turn off the alert, or ask us to delete them
Server logs — retained for up to 90 days for debugging purposes

7. Your Rights

You have the right to:

Access — request a copy of data we hold about you
Deletion — request deletion of data associated with your device (deleting the app removes all on-device data)
Portability — request an export of your data in a machine-readable format

To exercise any of these rights, email pipeprepai@gmail.com. We will respond within 30 days.

8. California Residents (CCPA)

If you are a California resident, you have the right to know what personal information we collect, the right to delete it, and the right to opt out of its sale. We do not sell personal information. For CCPA requests, contact pipeprepai@gmail.com.

9. Children

PipePrep AI is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided personal information, we will delete it immediately.

10. Changes to This Policy

We may update this policy from time to time. When we do, we will update the "Last Updated" date at the top of this page. Continued use of PipePrep AI after changes constitutes acceptance of the updated policy. For material changes, we will notify you via the app.
