Who else touches your data.
Every outside service that receives or stores customer data for B/side, found by reading every outbound call in our code. If it is not on this list, we do not send your data to it.
| Service | What for | What it receives | Region |
|---|---|---|---|
| Fly.io | Runs the app and keeps your projects | Your cuts and project names, plus the account you sign in with | Los Angeles, US |
| Cloudflare | Stores the editing copies of your footage | Editing copies and exports, and your camera originals only if you choose to put them in the cloud | On request |
| ElevenLabs | Transcription and voice-over | The audio of the clips you choose to transcribe, and the text you ask it to speak for a voice-over. When you ask to change the voice of a voice-over you recorded, that recording. Only when you ask. Since October 19, 2026, our account is set so ElevenLabs does not train its models on what we send it. | On request |
| Anthropic | The in-app assistant, switched off today | Nothing while it is off. When we turn it on: your question and a short summary of your project status (counts, plus a drive name when one is offline). Never footage, clip names or transcripts. | On request |
| Postmark | Email from the app | The recipient address and the message | On request |
| Sign in with Google | Your name and email address, nothing else | On request | |
| YouTube (Google) | Posting to your channel, switched off today | Nothing while it is off. When we turn it on, only if you connect a channel and post: the finished video, its title and description, who can watch it, and whether it is made for children. | On request |
| Instagram (Meta) | Posting to your account, switched off today | Nothing while it is off. When we turn it on, only if you connect an account and post: the finished video (which Instagram fetches from a temporary private link), its caption, and whether it also shows on your profile grid. | On request |
| TikTok | Posting to your account, switched off today | Nothing while it is off. When we turn it on, only if you connect an account and post: the finished video, its caption, who can watch it, whether comments, duets and stitches are allowed, and whether it is marked as commercial content. | On request |
| Stripe | Billing | Your email, card and billing address at checkout, the plan you chose, your payments and the renewal terms you agreed to. Card numbers stay with Stripe; we keep only its reference to you. If you set up referral payouts, Stripe holds your payout details. | On request |
Nothing tracks you in the app
There is no third-party analytics or script inside the B/side editor, and nothing records what you do while you cut. We only note a few firsts for each account, such as the first project and the first export, to learn what helps people get started.
Editing never depends on them
Transcription, the assistant, email and billing are all optional. If one of them is unavailable, you can still cut.
