WhatsApp will now allow you to securely add and manage contacts across all devices.
Previously, this feature was only available on smartphones, where contacts were added by phone number or via QR code. It will soon appear in the WhatsApp Web version.
Also in Russia there is the Federal Law "On Personal Data" from July 27, 2006 No. 152-FZ, which regulates the collection, storage and processing of personal data, including contact data collected for mailing via WhatsApp. When collecting and using personal data, it is necessary to comply with the requirements of the law, including obtaining consent for the processing of personal data and protecting it from unauthorized access.
Ignoring these rules when sending messages on WhatsApp or any other messenger may be considered a violation of advertising and personal data protection laws in Russia.
