Privacy Policy
Last updated: May 13, 2026
AI Pregnancy Calorie Calculator is a personal SaaS tool operated by Tao Xu. This policy explains what information is needed to provide pregnancy calorie estimates, AI nutrition guidance, account access, and optional Premium subscriptions.
Information we collect
We collect only the information needed to operate this service:
- Account data: your email address and password-protected login session when you create an account.
- Pregnancy calculator data: age, height, pre-pregnancy weight, pregnancy week, pregnancy type, activity level, unit preference, optional diet preferences, allergies, budget, cooking difficulty, and weekly weight records that you choose to enter.
- AI request data: the calculator result and the pregnancy nutrition question or customization request you submit, so the AI guidance can be generated.
- Payment data: subscription status, plan type, Stripe customer ID, renewal or expiration information, and payment event identifiers needed to manage Premium access.
- Technical data: standard hosting logs such as IP address, browser type, requested URL, date, time, and diagnostic events used for security and reliability.
Stripe payment processing
Payments are processed by Stripe. We do not store, process, or have access to your full credit card number, CVC, or card authentication details. Stripe may collect billing details and payment method information according to Stripe's own privacy and security practices.
How we use information
- To calculate daily pregnancy calorie goals, macro targets, weight gain references, and nutrition summaries.
- To generate AI-powered educational pregnancy nutrition guidance based on the inputs you provide.
- To create and manage your account, login session, password reset, subscription status, and Premium access.
- To provide customer support when you contact us.
- To protect the website, prevent abuse, debug errors, and improve service reliability.
Local browser storage
The website may store your recent calculator inputs and weekly tracker records in your browser's local storage. This helps you return to the calculator without re-entering everything. You can clear this data by clearing site data in your browser.
Sharing with service providers
We use service providers only where needed to operate the product: Vercel for hosting and serverless functions, a database provider for accounts and subscription state, Stripe for payments, Resend for password reset emails, and AI API providers for nutrition guidance requests. We do not sell personal data.
Health and pregnancy information
The pregnancy information you enter is used to produce educational nutrition estimates and AI guidance. It is not used for medical diagnosis, treatment, insurance decisions, or advertising profiling.
Data retention
Account and subscription records are kept while your account is active and as needed for security, legal, accounting, or dispute purposes. Browser local storage remains on your device until you clear it. Password reset tokens expire and are invalidated after use.
Your choices and rights
You may use the free calculator without subscribing. You may clear browser storage, cancel your subscription through Stripe, or contact us to request access, correction, or deletion of account-related data where applicable law allows.
Medical disclaimer
This service provides nutrition education only. It does not provide medical advice and does not replace your obstetrician, physician, registered dietitian, midwife, or qualified healthcare provider.
