E.g. how long you stopped by, what links you clicked on. We collect this via Google Analytics. We use it to improve our website.
E.g. # of downloads, how often the app is opened. This data collection is anonymous or requires opt-in. We use this data to track sales and improve the stickers app.
We make money of stickers, not your data.
We don't share any data, except in the sense that it is already shared with the collecting company (e.g. Google, Apple)
