Our Commitment
STAMPEDSAFE (“we,” “us,” or “our”) is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.
The short version: We don't collect your proof content. All cryptographic operations happen in your browser. We collect minimal analytics to improve the product.
1. Information We Do NOT Collect
StampedSafe is built on a local-first architecture. We never collect:
- Your proof content (messages, text, or ideas)
- Files you attach to proofs
- File contents or metadata
- Cryptographic keys generated for your proofs
- The proofs you create or verify
All proof creation and verification happens entirely in your browser. Your content is hashed and signed locally—it never leaves your device.
2. Information We Collect
2.1 Usage Analytics
We collect anonymous, aggregated usage data to improve StampedSafe:
- Page views and navigation patterns
- Feature usage (e.g., how many proofs are created, verification method used)
- Device type, browser, and operating system
- Geographic region (country-level only)
- Referrer URL
This data is collected without personal identifiers and cannot be used to identify you individually. We do not use cookies for tracking.
2.2 Payment Information
If you purchase a paid plan, payment processing is handled entirely by Stripe. We never see or store your full credit card number. We receive only:
- Email address (for receipts and account management)
- Last four digits of your card (for your reference)
- Transaction history
2.3 Support Communications
If you contact us via email, we retain your message and our response to provide support and improve our service.
2.4 Local Storage
StampedSafe stores data in your browser's local storage to maintain your proof history and usage limits. This data never leaves your device unless you explicitly share or export it.
3. How We Use Information
We use the information we collect to:
- Improve and optimize StampedSafe
- Understand how features are used
- Diagnose technical issues
- Prevent abuse and enforce usage limits
- Process payments for paid plans
- Respond to support requests
4. Data Sharing
We do not sell your personal information. We may share data only with:
- Service providers — Such as Stripe for payment processing and Vercel for hosting. These providers are bound by contract to protect your data.
- Legal requirements — If required by law, subpoena, or court order.
5. Data Retention
- Analytics data — Retained for 12 months, then aggregated or deleted.
- Payment records — Retained as required by tax and financial regulations.
- Support emails — Retained for 3 years.
- Local storage — Controlled entirely by you. Clear your browser data to delete.
6. Your Rights
Depending on your jurisdiction, you may have the right to:
- Access the personal information we hold about you
- Request correction of inaccurate information
- Request deletion of your personal information
- Object to or restrict processing
- Data portability
To exercise these rights, contact us at support@stampedsafe.com.
7. Security
We implement industry-standard security measures to protect the limited data we collect. However, no internet transmission is completely secure. See our Security page for details on our technical approach.
8. Children's Privacy
StampedSafe is not intended for children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of significant changes by posting a notice on our website. Your continued use of StampedSafe after changes constitutes acceptance of the updated policy.
