We use a variety of security measures to maintain the safety of your Personal Data. We take great care to ensure that your Personal Data is stored securely on our servers, and we follow the standards generally accepted in the industry to protect Personal Data submitted to us. In particular, we:

we encrypt many of our services using SSL (Secure Sockets Layer) when transmitting data. When a browser attempts to access a website that is secured by SSL, the browser and the web server establish a SSL connection, using keys. SSL creates a secure connection by establishing an encrypted connection.

hashing is used when storing passwords. Hashing is a one-way function in which a hashed value cannot be reversed to obtain the password. Only an encryption key can decrypt the password. Only the hashed password is stored by BestSub.

we review our information collection, storage and processing practices, including physical security measures, to guard against unauthorized access to systems.

We aim to maintain our services in a manner that protects Personal Data from accidental or malicious destruction. As a consequence, we may not immediately delete residual copies from our active servers and may not remove information from our backup systems. BestSub uses the Cloud server services of providers such as Amazon and Microsoft. These providers also store the information in the United States. Upon deletion of an account, this Personal Data is inaccessible to BestSub unless otherwise required by law.

We provide you with the opportunity to “opt-out” of having your Personal Data used for certain purposes.
