Privacy Policy
Last updated November 12, 2026
This is how Human Repair Workshop LLC (Human Repair Workshop) handles your information in Spare Brain, which includes the Spare Brain app, the Spare Brain texting number, and this website. Spare Brain is in testing. We will update this page before Spare Brain opens to the public, and we will tell account holders whenever it changes.
What we collect
- When you ask to join the test: your name, email address, mobile number, and whether you agreed to texts.
- When you use Spare Brain: your name, email address, and mobile number, and what you send to Spare Brain (texts, photos, screenshots, forwarded emails, and lists). We also keep the items, notes, and plans you create.
- Only if you connect them: your calendar, your phone's contacts, and work accounts such as Slack, Zoom, or email. You can disconnect any of them at any time.
We don't ask for health information, and we don't use advertising trackers.
How we use it
- To turn what you send into items, plan your day, and prepare drafts of your next steps.
- To reply to your texts and send the texts you agreed to.
- To run your organization's Work side for its members, if you belong to one.
- To keep Spare Brain secure and to fix problems.
We don't sell your information, and we don't use it for advertising.
How Spare Brain uses AI
Spare Brain uses Claude, an AI model made by Anthropic, to read what you send and to draft your next steps. Anthropic processes that content only to provide the service to us, and it does not use it to train its models. Spare Brain doesn't send, pay, or call anything without your approval. The one exception is reminders on a schedule that the person running a group set up in advance, such as reminders for a circle you joined.
Text messages
If you agree to texts, Spare Brain texts you to confirm what it saved, with your plan for the day, and with reminders you set. How often depends on how much you send. Message and data rates may apply. Reply STOP to any text to stop them, or HELP for help. We use your number only for Spare Brain.
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent will not be shared with any third parties. Our SMS Terms have the details.
Who can see your information
Only you can see your Home side. On a Work side, the members of that organization can see its work. Human Repair Workshop staff look at account information only when they need to help you or to keep Spare Brain secure.
The services we use
Spare Brain runs on Cloudflare and stores its data with Supabase. Texts go through Twilio, and the AI is Anthropic's. When you connect Google, Microsoft, Slack, or Zoom, Spare Brain reads from that service with your permission. These companies handle your information only to provide their service to us.
Keeping and deleting your information
We keep your information while you have an account. To get a copy of everything, correct something, or delete your account and everything in it, email hello@humanrepair.org. We will finish a deletion within 30 days.
Children
Spare Brain accounts are for adults. We don't knowingly collect information from children under 13.
