Privacy
Last updated 21 August 2026.
Flitterby moves files between cloud storage providers on your instruction. This page describes exactly what that involves, in plain terms.
Flitterby is a service operated by Serious Business Software LLC, which is the data controller for everything described below. “We” and “us” mean that company.
What we store
- Your account: the email address and name your sign-in provider gives us.
- Access to your providers: authorization tokens for the accounts you connect, encrypted before they are written down. We never see or store your provider passwords.
- A list of what to move: for each transfer we record file names, paths, sizes, timestamps and checksums, so a transfer can resume and be verified.
- Waitlist emails, if you asked for an invite.
What we do not store
The contents of your files. File data streams from the source provider to the destination provider through memory and is never written to our storage. When a transfer finishes, no copy of your file exists on our systems, because none ever did.
We do not store your IP address against waitlist signups, and we do not use advertising or analytics trackers.
What we access
We request the narrowest access each provider offers for the job: permission to read from a source and to create files at a destination. We do not request permission to delete your files. You can revoke access at any time from the provider's own security settings, and doing so immediately stops Flitterby reaching your account.
Who we share it with
Nobody. Your data is not sold, rented, or shared with third parties. The only places your file data travels are the two providers you chose.
Where it runs
Flitterby runs on Cloudflare Workers. Account records, transfer manifests and encrypted tokens are stored in Cloudflare's databases.
Deleting your data
Email support@flitterby.com and we will delete your account, your connections and your transfer history. Disconnecting a provider removes its stored token immediately.
