Data We Collect
We collect the following types of information:
- Payment Information: Processed securely through Stripe. We do not store credit card details.
- Message Content: The text you submit for blockchain anchoring (maximum 80 bytes).
- Email Address: Used for sending confirmation emails and certificates.

Data Storage & Security
Your data is stored in EU-based servers with encryption at rest. We implement industry-standard security measures to protect your information. However, no method of transmission over the internet is 100% secure.
Public Blockchain Data
Once anchored, your message becomes part of the Bitcoin blockchain and is permanently public. This is by design—permanence is the core feature of our service. Do not include personal data, secrets, or sensitive information in your messages.
Third-Party Services
- Stripe: Payment processing (subject to Stripe’s privacy policy)
- Brevo: Email service for sending certificates and notifications (subject to Brevo’s privacy policy)
Your Rights (GDPR)
If you are in the EU, you have the right to:
- Access your personal data
- Request correction of inaccurate data
- Request deletion of your data (except blockchain-anchored content)
- Object to processing of your data
- Request data portability
Important: Once a message is anchored to the blockchain, it cannot be deleted or modified. This is a fundamental characteristic of blockchain technology. Therefore personal data must not be included in the message.
