XContent stores the minimum data needed to operate the service: your account details, profile inputs, Telegram link, subscription state, generated packs, and operational logs.
We use that data to generate and deliver content packs, manage billing access, and debug failures. We do not require access to your X/Twitter account.
If you want your data removed, contact support and we can delete your account, linked Telegram record, and stored packs unless we are required to keep billing records for compliance.
