برنامه‌های موبایل و خریدهای درون‌برنامه‌ای
برنامه‌های iOS و Android sum.video همان حساب‌ها و خلاصه‌ها را با وب‌سایت به اشتراک می‌گذارند، با این تفاوت‌ها:
- اشتراک‌های پرو خریداری شده در برنامه‌ها توسط اپ استور اپل یا گوگل پلی صورت‌حساب می‌شوند، نه توسط Stripe.
- ما از RevenueCat برای اعتبارسنجی رسیدهای فروشگاه و همگام‌سازی وضعیت اشتراک با حساب شما استفاده می‌کنیم.
- برنامه‌های موبایل شامل تجزیه و تحلیل PostHog یا SDKهای ردیابی تبلیغات نیستند.
- می‌توانید حساب خود را از بخش حساب در برنامه موبایل یا از داشبورد خود در وب‌سایت حذف کنید. این کار داده‌های حساب شخصی شما را در sum.video حذف می‌کند.
- حذف حساب شما یک اشتراک فعال اپ استور یا گوگل پلی را لغو نمی‌کند. آنها را در تنظیمات اشتراک Apple ID یا Google Play لغو کنید.
کانکتورهای Claude و ChatGPT
اگر Claude یا ChatGPT را به sum.video متصل کنید، این برنامه‌ها URLهای ویدیوی یوتیوب و سوالاتی را که از طریق کانکتور می‌پرسید، ارسال می‌کنند. ما آنها را تحت حساب موجود شما، سهمیه هفتگی خلاصه و سهمیه چت شما پردازش می‌کنیم. ما بقیه مکالمه Claude یا ChatGPT شما را دریافت نمی‌کنیم.
