Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more users, faster growth over 30 days, a higher rating, more ratings, a fresher update, more new versions, more languages, a store badge, a privacy policy), the better one is also marked green with ▲ and the worse one red with ▼. Permissions, site access, declared data, size and time in the store are marked only as different: fewer or more is not better in itself.

What data each declares

Tab Out: The developer declares that it does not collect or use your data.
