Your family data is yours. Period.

Last updated: March 2026

Our commitment

fuel is built by a parent, for families. We take your privacy as seriously as we take our own family's. This policy explains what data we collect, why, and how we protect it.

What we collect

Account information

When you create an account, we collect:

  • Email address (for login and communication)
  • Password (encrypted, never stored in plain text)
  • Family member names and basic profiles (for meal suggestions)

Nutrition data

To provide meal suggestions, we collect:

  • Nutrition goals and preferences
  • Meal history and portion adjustments
  • Dietary restrictions (if provided)

Usage data

To improve our service, we collect:

  • Anonymous analytics (page views, feature usage)
  • Error reports (to fix bugs)

What we do

  • Store only what's needed to provide the service
  • Encrypt sensitive data at rest and in transit
  • Use industry-standard security practices
  • Help you delete your data on request
  • Notify you of any security incidents

What we don't do

  • Sell your data to anyone, ever
  • Run ads or share data with advertisers
  • Track you across other websites
  • Use your data for training AI models without consent
  • Share your information with third parties for marketing

Children's data

We take extra care with children's information:

  • Children's data is used only for meal planning and Questy rewards
  • Children never see macro numbers or calorie counts
  • We never market to children
  • Children's data is never shared with third parties
  • Parents have full control over their children's data

Third-party services

We use these trusted services to operate fuel:

  • Stripe — payment processing (they have their own privacy policy)
  • Vercel — hosting and infrastructure
  • OpenAI — AI meal suggestions (we send only anonymized data: age ranges, dietary restrictions, and nutrition targets — never names, emails, or device info)

We carefully vet all third parties and only share the minimum data necessary.

AI Features & Data Processing

Fuel uses AI to generate personalized meal suggestions. When this feature is enabled by a parent:

What is sent to our AI provider

  • Anonymized member tokens (e.g., 'Member 1'), never real names
  • Dietary restrictions and macro targets
  • Activity type for the day (e.g., 'rest day', 'training day')
  • Taste preferences (e.g., 'prefers spicy food')

What is never sent

  • Family member names or nicknames
  • Email addresses or account identifiers
  • Exact ages or birthdates
  • Location or device information
  • AI features require explicit parental consent
  • Consent can be revoked anytime in Family Settings
  • AI provider does not store prompts per our enterprise agreement
  • All data is anonymized before leaving Fuel servers

Your rights

You can always:

  • Access all data we have about you
  • Export your data in a standard format
  • Delete your account and all associated data
  • Update or correct any information
  • Opt out of non-essential communications
