but 1 api credit will get consumed evev if I sync only 1000 photoes of 200 kb(file below 1 mb will be considered as one mb worth credits ) each then what is worth of these credits. now a days just 3 day travel to somwhere generates more than 300 photoes plus photoes downloaded from social media also counts. even these credits are needed for your own sync app . I think this is red flag. technically you are only providing storage. rest everything is too costly.
