Privacy Policy
Last updated 22 October 2026
CartKing helps Australian households plan dinners around a grocery budget. This policy explains what we collect, why, and the choices you have. We follow the Australian Privacy Principles.
What we collect
- Account details: your email address and a password (stored securely by our login provider, never in plain text).
- What you tell us to plan with: budget, number of adults and children, dinners per week, dietary needs, foods to avoid, supermarket choice and pantry items.
- What you create: meal plans, shopping lists, saved meals and any edits you make.
- Plan usage and subscription status, so we can apply plan limits and give you Pro features.
- Basic technical logs kept by our hosting provider for security and fixing faults.
We do not collect your location, contacts, photos or advertising identifiers, and CartKing has no ads and does not track you across other apps or websites.
How we use it
- To create your account and keep you signed in.
- To generate meal plans and shopping lists, and to estimate prices.
- To manage your plan, including billing for Pro on the website.
- To send reminders you have asked for. On iPhone, the Sunday reminder is a notification scheduled on your phone and sends nothing to us.
- To keep the service secure and working.
Who we share it with
We use service providers to run CartKing. We do not sell your information.
- Supabase: stores your account and data.
- Vercel: hosts the app and website.
- An AI service: your plan settings (budget, household size, dietary needs, foods to avoid and pantry items) are sent to a language model to write meal plans. We do not send your email address or name.
- Stripe: processes Pro payments made on the website. It handles your card details, and we never see or store them.
- Resend: sends reminder emails, using your email address, if you have asked for them.
- Photo and price data providers: meal names and ingredient names are sent to look up photos and prices.
Some of these providers store or process data outside Australia.
Keeping and deleting your data
We keep your data while you have an account. You can delete your account at any time in Settings, then Delete account. This removes your plans, saved meals and login and cancels any subscription we manage. Payment providers may keep billing records where the law requires it.
Your rights
You can ask to see or correct the personal information we hold about you, or raise a privacy concern, by contacting our support page. If you are not satisfied with our response, you can contact the Office of the Australian Information Commissioner.
Children
CartKing is not directed at children under 13, and we do not knowingly collect their information.
Changes
If we change this policy we will update the date above. For significant changes we will tell you in the app.
