By default Reports.Python runs in trial mode with a watermark; applying your license key removes it.

Register the license key.
from stimulsoft_reports import StiLicense

# From a key file...
StiLicense.setFile(url_for('static', filename='private/stimulsoft.key'))

# ...or from a key string
StiLicense.setKey('6vJhGtLLLz2GNviWmUTrhSqnO...')

How it works. The license is registered once at startup, so every report and component in the app renders without the trial banner.
