Hi @Corner 
It’s not possible to set up row-level permissions in Airtable. You can use Airtable’s filter by formula to fetch only the data you need. This will make it harder for someone with bad intentions to access your user data but it won’t be fully secure because, without RLS, someone who knows what they’re doing can modify the API call to fetch information you intended to keep secure.
I would recommend using a state-of-the-art backend like Xano and Supabase if you are working with private data.
