With hashcloud – your new cloud storage - you can easily share files using #hashtags. Simply come up with a new #hashtag and share it with friends or colleagues. Anyone who knows this #hashtag can then upload files to it and download files from other users. This makes hashcloud perfect for exchanging files at university, at work, among friends, or within the family. Hashcloud is a cloud storage service designed specifically for easy file sharing. You no longer need to ask for contact information from people you want to collaborate with. Nor do you need to create complicated and confusing links to send to these individuals. With hashcloud, you simply come up with a suitable #hashtag that best describes your group work or file directory. The involved parties can easily remember this #hashtag and enter it into their app. The cloud storage is completely hosted in Germany. All files are stored on German servers and are thus subject to GDPR. So, you don't have to worry about your files falling into the wrong hands. Also, a #hashtag acts like a password. The more difficult and unique your #hashtag is, the less likely someone will access your files. Conversely, you can also create open #hashtags, for example, if you want to share files with as many users as possible. However, if you want to be completely secure, simply add a password to your #hashtag. You must be an admin or the creator of the #hashtag to do this. Other users can only join the #hashtag if they also know your chosen password. So, your files are always protected in hashcloud storage. Here's a list of all features: + File sharing via #hashtags – Avoid cumbersome links and share your files using easy-to-remember #hashtags + Access to all files (free and without registration/login) at www.hash.cloud + All files and user data are stored on German servers and are subject to GDPR + Password protection for extremely sensitive files + Available as an iOS and web app (www.hash.cloud) + Upload up to 10 files simultaneously Accessing files is completely free. Only for uploading new files, you need to purchase a quota. You can test the platform with up to 1GB of storage for uploading files. If you need more storage, please consider upgrading to hashcloud+ with 1,000GB of storage. For more information, visit www.hash.cloud. For questions and suggestions, we are available at help@hash.cloud at any time.

Verdict

The call

The clearest difference is rating: hashcloud at 4.5 against Rainbow's 3.6. hashcloud also leads on update cadence (every 8 days vs every 2 months) and review sentiment (41% vs 20%). Rainbow's advantage is ads (none vs shown) and iOS requirement (11.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.
