Supabase Row Level Security keeps AI-built mobile data safe from day one
AI-built mobile apps ship fast because the backend feels solved. You add Supabase auth, create a few tables, paste the anon key into your Expo config, and rows start flowing. That speed hides one uncomfortable fact: the anon key ships inside your client, and anyone can pull it out of the bundle and call your database directly.
Row Level Security is the layer that makes that safe. It runs inside Postgres, on every query, no matter which client or script sent it. When it is set up well, a signed-in user only ever sees their own rows, anonymous visitors see only what is truly public, and everything else is denied before it leaves the database.
When it is missing, your app works perfectly in testing and leaks quietly in production. You will not get an error.
