MyTower is a SaaS platform from the French company MyTower for transport management and international trade, aimed at shippers. The TMS solutions include road and overseas transport, import supply chains, freight invoice control, appointment booking and carbon-footprint calculation. The GTM solutions cover customs (tariff classification, origin calculation, customs declarations and management of customs brokers), export control and trade compliance, plus analytics. The modules are configurable.
MyTower is a French SAS with its registered seat in Paris; the site names no owner in another country. It does not state where customer data is hosted in the SaaS environment; the website itself runs with a French host. The privacy policy says the vendor complies with the European data protection regulation and that personal data may be transferred to service providers in third countries, with safeguards. For your situation, ask about the hosting location and the list of sub-processors.
