Lucky Numbers only collects what you give it to make the app work:
We do not collect location data, contacts, advertising identifiers, or analytics beyond basic server logs.
Your data is used for exactly one thing: running the app for you — building your plan, tracking your progress, grading your days, and answering your coach questions. We do not sell your data, share it with advertisers, or use it for marketing.
Data is stored with Supabase (our database and authentication provider) on infrastructure hosted in the United States. Access is protected by row-level security: your records are readable and writable only by your signed-in account. Progress photos are stored in a storage bucket tied to your account.
When you use AI features (food recognition, the coach), the relevant content — your message, photo, or description, plus the minimal context needed to answer, such as today's remaining macros and your goal — is sent to Anthropic's API for processing. It is used to generate your answer, not for advertising.
Weight, sleep, nutrition, and supplement logs are sensitive. We treat them that way: they are never shared with third parties except the processors named above (Supabase to store, Anthropic to answer your AI requests), never sold, and never used for anything other than showing you your own progress and powering your own plan.
The app uses browser storage on your own device to keep you signed in. There are no third-party cookies, trackers, or ad pixels.
Lucky Numbers is not intended for anyone under 18, and we do not knowingly collect data from minors.
If this policy changes materially, we will note the new effective date here. Continued use after a change means you accept it.
