1. User navigates to main page
2. User enters email and clicks 'send email'
3. Server generates an 'access token' and sends an email to the user
4. The user receives the email and clicks a link, that sends the server
   the 'access token' and the email.
5. The server verifies the 'access token' and the email, and then
   navigates the user to the next page that asks for more info to be entered
6. The user enters the info such as 'name', 'telephone' and an optional 'message',
   then selects the files to be send, and clicks 'Sent' button
7. The server receives all the info and the files, downloads and packs the files into a .zip
   It sends the 'administrator' an email to notify that a new file have been received,
   and it optinally sends a Telegram message to further notify the administrator.
8. The administrator receives an email that notifies him about the uploaded data,
   and a link is presented so he can download data to his computer

Checking requirements
1. The generated 'access token' in step 3, is stored in the database, along with
   datestamp it was generated and user email, this token has a limited expiration time,
   because the user has to upload the data in a reasonable time, can like 60 minutes.

2. After the user enters more info, these info are stored in the database also for future
   reference, these info have a more extended expiration time, since the administrator should
   have time to review them, it can be like 7 days or a few weeks.

3. OPTIONALLY the user can be informed that his/her data will be permanently deleted from the server
   in a specific amount of time, also he/she may be informed about file deletion after expiration date.
