What we collect
Quartermaster collects the minimum data needed to provide the service. This includes account and authentication data, plus the Recipes, classifications, Menus, Meals, Staples/Out state, Shopping, and archived Pantry recovery data your household creates.
How we use your data
Your data is used solely to provide and improve the Quartermaster service. We use PostHog for product analytics to understand how features are used and to fix bugs. We do not sell your data or use it for advertising.
Optional AI and voice tools
When you choose AI Recipe import, the text or images you provide are sent to Anthropic. Recipe enhancement sends that Recipe's title, description, ingredients, instructions, and existing times to Anthropic. Voice input sends your audio to Groq for transcription; the transcript may then be sent to Anthropic to parse Shopping items. These tools run only when you choose them.
Analytics and session replay
Quartermaster uses PostHog to capture anonymous pageviews, clicks, and session recordings (DOM snapshots — visible page text is recorded, but form input values are masked by default). This helps us understand usage patterns and diagnose issues. You can opt out at any time by running posthog.opt_out_capturing() in your browser console.
Data storage
Your data is stored in a SQLite database hosted on Fly.io infrastructure. Database backups and Recipe images are stored in S3-compatible object storage. Connections use HTTPS encryption in transit.
Cookies
We use a single httpOnly session cookie for authentication and a theme preference cookie. PostHog sets an analytics cookie for identified users (only created after you log in, per our person_profiles: 'identified_only' configuration). We do not use advertising cookies.
Data export and deletion
You can download a JSON export of your profile and household Recipes, classifications, Staples/Out state, archived Pantry recovery data, Menus, Plans, and Shopping. Recipe images are referenced rather than embedded. Go to Settings > Profile to export your data or delete your account. Data belonging to a shared household may remain available to its other members.
Changes
We may update this policy as the service evolves. Significant changes will be communicated through the app.
