Aplikasi seluler dan pembelian dalam aplikasi
Aplikasi sum.video iOS dan Android menggunakan akun dan ringkasan yang sama dengan situs web, dengan perbedaan berikut:
- Langganan Pro yang dibeli di aplikasi ditagih oleh Apple App Store atau Google Play, bukan oleh Stripe.
- Kami menggunakan RevenueCat untuk memvalidasi tanda terima toko dan menyinkronkan status langganan ke akunmu.
- Aplikasi seluler tidak menyertakan analitik PostHog atau SDK pelacakan iklan.
- Kamu bisa menghapus akunmu dari Akun di aplikasi seluler atau dari dasbor di situs web. Itu akan menghapus data akun pribadimu di sum.video.
- Menghapus akunmu tidak membatalkan langganan App Store atau Google Play yang aktif. Batalkan itu di pengaturan Apple ID atau langganan Google Play.
Claude and ChatGPT connectors
If you connect Claude or ChatGPT to sum.video, those apps send the YouTube video URLs and questions you ask through the connector. We process them under your existing account, weekly summary quota, and chat quota. We do not receive the rest of your Claude or ChatGPT conversation.
