Frequently Asked Questions
Are there any additional installations needed for S3 Sidekick?
Install the package for your operating system from the current release. The packaged app includes its runtime dependencies.
Which S3-compatible services work?
S3 Sidekick is intended for services with an S3-compatible API, including AWS S3, MinIO, Cloudflare R2, and Backblaze B2. You must enter the endpoint, region, bucket, and credential details expected by your provider.
How are credentials stored?
When credential encryption is enabled, the local vault encrypts credentials with AES-256-GCM and derives its key with PBKDF2-HMAC-SHA256. The app also allows unencrypted local storage, so check the security status before saving a connection. Object traffic goes to the endpoint you configure, and the app does not send credentials to Rosie.run.
Does S3 Sidekick check for updates automatically?
The app can check GitHub releases on startup and download an update after you confirm. You can disable update checks in Settings and install releases manually.
What is S3 Sidekick’s Privacy Policy?
Read the S3 Sidekick Privacy Policy for vault storage, object traffic, updater requests, and telemetry behavior.
S3 Sidekick is open source, what license does it use?
S3 Sidekick is published under the Mozilla Public License 2.0. Read the repository license for its complete terms.
