I’m looking for FOSS cloud storage that has an app not in the Play Store as I’m running Graphene OS and looking to stay away from the Play Store / Aurura store. Any ideas ?
You can use filen.io, which I like. It’s based in Germany and GDPR compliant.
Their app is on github, so you could use obtainium to manage it: https://github.com/FilenCloudDienste/filen-mobile/releases/tag/v3.0.25
+1 for Filen. I use it for its E2EE.
I also use infomaniak’s Kdrive (Swiss-made) with their ‘KSuite’ offer, for everyday cloud storage. It’s cheap for 1To (more available, if needed). I don’t think they’re open source. More info: https://www.infomaniak.com/en/ksuite
I like filen too. I don’t know if they still do it but you used to be able to buy lifetime plans and stack them, so I picked up 300Gb of storage without a recurring subscription by just buying a plan every time there was a sale/Black Friday thing.
Nextcloud
Syncthing
CopyParty https://github.com/9001/copyparty + PartyUp https://f-droid.org/packages/me.ocv.partyup/ (upload only, not sync)
Could try https://f-droid.org/packages/com.phpbg.easysync/ for sync proper.
More WebDAV Android client options https://github.com/fstanis/awesome-webdav#android but anyway my suggestion is to rely on a protocol, not an app.
Selfhost Nextcloud.
I selfhost NextCloud, and I haven’t had any problems at all… and it’s between windows, android and linux…
Self host filebrowser quantum! Small, light and easy to configure.
It is currently in beta, but it is on the cusp of a stable release.
Ipfs or possibly arweave
I’m using an anon Dropbox account service through Cryptomator. Cryotomator is a really strong encryption cloud storage app. It just uses your Dropbox account to upload it. Cryotomator might be open-source but dropbox definitely isn’t. So sorta?
Seems like Seafile has an app on FDroid: https://f-droid.org/en/packages/com.seafile.seadroid2/
Try koofr
