The app unexpectedly stopped working in the offline mode (I had been using it in this mode for a couple of years) and suggested that I download some huge amount of data. It took a lot of time and couldn't be comlleted anyway. I tried to reinstall the app and it demanded access to my personal data including photo and video. Good bye, "Oxford Dictionary of English"

Sorry to hear you are unsatisfied. We have a newer, a tad larger and considerably better Offline and Audio database. Please note that the app needs certain access - i.e. internal storage in order to save your favorites or access to you camera to translate captured words. Contact us at support@mobisystems.com and we'll assist further.

I have cancelled subscription after 3 years. It used to be a good app. After this last update it turned into uncomfortable and very slow pathetic dictionary with animations over usability. Update after some time: I found out you made a ridiculously high subscription price. Are you serious? This is a dictionary you can use for free online on the official web. Uninstalling.

Not sure why you would need the financial data info,along with app activity which basically covers most of it. Even if I were to think it was for ads, it would be wishful thinking. The data will reach the depths where no light shall ever reach or have reached. Also, if you are forcing in app purchases for so many things then why would a user share their data with you? because you want the best of both worlds.
