No, it is not safe or advisable to message or share files outside the Ostathi platform. Keeping all your communications and file exchanges within Ostathi is crucial for your protection and to ensure a secure and supported learning experience:

Security and Privacy: When you use Ostathi's integrated messaging and file-sharing tools, all your data is stored securely on our platform, which is built on a robust cloud infrastructure. This protects your personal information and communication content.
Official Record and Accountability: Communications and shared files on Ostathi create an official record. This is vital for accountability, quality control, and allows Ostathi to review interactions if any issues or disputes arise. Using external apps like WhatsApp or email means there is no official record, making it impossible for Ostathi to assist you if something goes wrong.

By staying on the platform for all messaging and file sharing, you ensure that you benefit from Ostathi's full suite of security, support, and dispute resolution mechanisms.
