We implement appropriate technical and organizational measures to protect your data, including encryption and restricted access. However, no system can be 100% secure, and we cannot guarantee absolute security.
The App is not directed at individuals under 16 years of age (or the minimum age required by local law). We do not knowingly collect personal data from children. If we become aware that we have collected such data, we will delete it immediately.
