Privacy Policy
Effective Date: April 16, 2026
Bobbin Operating LLC ("Bobbin", "we", "us", or "our") operates the Bobbin mobile application and website. This Privacy Policy describes how we collect, use, and protect your personal information.
1. Information We Collect
We collect the following types of information:
- Account Information: Name, email address, and authentication credentials when you create an account via Apple Sign-In, Google Sign-In, or email registration.
- Design Data: Embroidery designs, projects, and related files you create or import within the app. These are stored locally on your device and optionally synced via iCloud or Bobbin Cloud.
- Device Information: Device model, operating system version, and app version for support and compatibility purposes.
- Usage Data: Anonymous analytics about feature usage to improve the app experience (only when you opt in).
- Thread Inventory: Thread colors and brands you add to your collection, stored locally and optionally synced.
- Waitlist Signups: If you join our pre-launch waitlist on bobbinapp.com, we collect your email address, the timestamp of your signup, the section of the page you signed up from, and a salted hash of your IP address used solely for abuse prevention. See Section 11 for details.
2. How We Use Your Information
- To provide and maintain the Bobbin app and services
- To authenticate your identity and manage your account
- To sync your designs and preferences across devices
- To enable real-time collaboration features
- To process support tickets and respond to inquiries
- To improve the app based on aggregated, anonymized usage patterns
- To send a single launch notification to waitlist subscribers when Bobbin becomes available on the App Store
3. Data Storage and Security
Your designs and projects are stored locally on your device using Apple's SwiftData framework. If you enable cloud sync, data is stored in your personal iCloud container (managed by Apple) or Bobbin Cloud (hosted on AWS with encryption at rest and in transit).
Authentication tokens are stored securely in the iOS Keychain. We never store passwords in plaintext.
4. Phone Number Privacy
When you use phone number-based friend discovery, your phone number is hashed (SHA-256) on your device before being sent to our servers. We never receive, store, or process your plaintext phone number.
5. Third-Party Services
Bobbin integrates with the following third-party services:
- Apple Sign-In: Authentication via Apple's identity service
- Google Sign-In: Authentication via Google's identity service
- Amazon Web Services (AWS): Backend infrastructure including API hosting, database, and file storage
- Apple iCloud: Optional cloud sync for designs (controlled by your iCloud settings)
Our marketing website (bobbinapp.com) does not use third-party analytics, advertising trackers, or social-media pixels. All fonts and assets are served from our own origin — no requests are made to Google Fonts or any other third party from this site.
6. Data Sharing
We do not sell, trade, or rent your personal information to third parties. We may share data only:
- With your explicit consent (e.g., sharing a design with a collaborator)
- To comply with legal obligations or law enforcement requests
- To protect the rights, property, or safety of Bobbin and its users
7. Your Rights
You have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your account and associated data
- Export your designs in standard embroidery formats
- Opt out of analytics tracking
- Unsubscribe from the waitlist at any time by emailing us at the address below
8. Children's Privacy
Bobbin is not intended for children under the age of 13. We do not knowingly collect personal information from children.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy in the app and on our website.

11. Pre-Launch Waitlist
If you join our pre-launch waitlist on bobbinapp.com, we collect:
- Your email address
- The timestamp of your signup
- An identifier for which section of the page you signed up from (used to understand which CTAs are most effective)
- Your browser's User-Agent string (truncated)
- A SHA-256 salted hash of your IP address — we do not store the IP itself; the hash is used solely to detect and prevent abusive signup behavior
We use this information for one purpose only: to send you a single email when Bobbin launches on the App Store. You will not receive marketing emails, newsletters, or any other communications. You may unsubscribe at any time by emailing privacy@bobbinapp.com and we will delete your record from our systems.
