By using FactomRobot.com & it's bot @FactomRobot you have to agree with the following:
We don’t store your files: once you send the file to the bot, it’s uploaded on the Telegram servers and stored there.
We store your Telegram name, author name, the list of uploaded files and detailed information about them to show it in your account.
Your personal information is never made publicly visible on the blockchain. Instead, we store a digital fingerprint known as a "hash". The process cannot be reversed, so your documents are safe from prying eyes.
We DO NOT use your files & personal information for any malicious activity and we DO NOT share it with other parties.
Your account and files are publicly available by specific URLs. Account URL may be received only via your Telegram account. Other parties don’t know your account URL and files URLs until you share it with them.
Once you agree with terms in the Telegram chat with our bot, the agreement record will be saved on the public blockchain as a hash.
