MyExpatTaxes was designed with security in mind from day one. The architects and lead developers have 20+ years experience in creating secure web applications.
On all infrastructure levels, the software uses state-of-the-art security best practices. Data is encrypted at transport and wherever possible on rest. Passwords or security question answers are stored as hashes only, so that not even MyExpatTaxes can read these data. MyExpatTaxes does not store any credit card information.
