Bhai, jab consent mutual hai toh phone ke built-in Family Sharing ya Google backup/sync features hi kaafi hain, kisi extra app ki zaroorat nahi padti. Main teen age mein jab parents ne same kiya tha, shuru mein safe feel hua par baar-baar monitoring ne bas mujhe chup-chap better jhoothna sikha diya. Clear rules + beech-beech mein honest baat-cheet actually trust build karti hai, warna ye setup trust ke bajaye thoda weird power imbalance jaisa lagne lagta hai.
