Privacy Policy

Effective date: May 28, 2026 · Last updated: October 18, 2026

1. What we collect

Account information — your email address and name, collected through Clerk when you sign up.

Usage data — counts of questions asked, checklists generated, and files uploaded each month. Used solely to enforce your plan limits.

Chat messages and photos — sent to our AI backend to generate responses. We do not store chat history beyond your active session.

Billing information — payments are handled by the store you buy through: Stripe on the web, Apple (App Store) on iPhone, or Google Play on Android. We never see or store card details. We store only your plan, its renewal date, and the customer or subscription identifier the store gives us (relayed to us by RevenueCat for App Store and Google Play purchases).

WhatsApp phone number — if you choose to link your WhatsApp account, we store your phone number to connect your WhatsApp messages to your app account. WhatsApp messages you send are processed by our AI backend to generate responses and are not stored after the response is delivered.

2. How we use it

  • ›Authenticate you and maintain your account
  • ›Enforce monthly usage limits by plan tier
  • ›Generate AI responses to your safety questions
  • ›Process subscription payments and renewals

Each provider has its own privacy policy. AI providers receive only the content of your messages — no account identifiers.

4. Data retention

Account and usage data is retained while your account is active and deleted within 30 days of account deletion. Chat messages and uploaded photos are not stored after your session ends. Stripe, Apple, and Google retain their own billing records as required by financial regulations; deleting your account does not cancel a store subscription, which you manage in your App Store or Google Play account settings.

5. Your rights

You may request deletion of your account and associated data at any time by contacting us. To delete your account, email us and we will remove all personal data within 30 days.

6. Children

This app is not directed at children under 13. We do not knowingly collect personal information from children.

7. Changes

We may update this policy. Material changes will be communicated via in-app notice or email. Continued use after changes constitutes acceptance.
