Congrats on the launch! But, something that stops me from using a number of services is the sale of fixed size plans where I'll typically either under utilize them (e.g. do I have 100 GB of screenshots to upload) or I'll over utilize and might not have an upgrade path immediately available for more storage.
I tend to toss my photos in backblaze or S3 for this reason -- UX is severely lacking but I pay for what I use. I'm curious how you landed on the subscriptions you chose + whether you'd consider usage based plans?
