Banks, NASA, FBI have all been hacked in the past so I won't have the immaturity to say that your data is 100% safe here.
We have taken measures to protect it and so far (three years in) we haven't received any report of a data breach but it could be a result of the fact WeekPlan is too unknown to attract any villain.
