Privacy Policy
Last updated: March 2026
1. Data We Collect
When you use ChainEvidence, we collect the information necessary to perform blockchain investigations and deliver reports. This includes Bitcoin (BTC) and Ethereum (ETH) addresses and transaction hashes you submit, your email address for account and notification purposes, domain names and IP addresses discovered during the investigation process, payment information processed securely through Stripe (we do not store your full card details on our servers), and your billing country (provided to Stripe at checkout) which we use solely to include jurisdiction-specific reporting guidance in your report.
2. How We Use Your Data
We use the data we collect to perform blockchain tracing and generate investigation reports, to send you notifications about your investigation status and report availability, and to improve the accuracy, reliability, and functionality of our service. We do not sell your personal data to third parties.
3. Third-Party Services
To deliver comprehensive investigation reports, we integrate with the following third-party services:
- Stripe — Stripe — Processes all payments securely. Stripe receives your payment details (card number, billing address) and is subject to its own privacy policy.
- TxShield API — TxShield API — Provides blockchain analysis data used to trace transactions, identify wallet clusters, and map the flow of funds across the Bitcoin network.
- Threat Intelligence — Threat Intelligence — Scans domains and URLs associated with investigated addresses against multiple security databases to detect known malicious activity, phishing campaigns, or scam infrastructure.
- WHOIS Lookup — WhoisXML — Retrieves domain registration records (WHOIS data) for websites linked to investigated entities, providing ownership and registration details.
- IP Geolocation — ipinfo — Provides geolocation and network information for IP addresses discovered during investigations, helping to establish geographic context.
Each third-party service receives only the data necessary to fulfil its specific function. We encourage you to review their respective privacy policies.
4. Data Retention
We retain your data only as long as necessary. Specific retention periods are:
- Investigation data (addresses, reports, metadata): 12 months from creation, then permanently deleted via automated cleanup
- Payment records and invoices: retained as required by German tax law (§ 147 AO), typically 10 years
- Email addresses: deleted together with the associated investigation data after 12 months
- Server access logs: 30 days, anonymized IP addresses
You can request early deletion of your investigation data at any time by contacting support@chainevidence.net. We will process deletion requests within 30 days, subject to legal retention requirements.
5. Automated Processing
ChainEvidence uses automated systems, including machine learning and algorithmic analysis, to process blockchain data, assess risk scores, and generate investigation reports. These automated processes analyze on-chain transaction patterns, wallet behaviors, and publicly available data to produce findings and risk assessments. No automated decision made by our service has legal or similarly significant effects on you — all reports are informational tools intended to support your own decision-making. You may contact us at any time to request information about the logic involved in our automated processing.
6. Legal Basis for Processing
If you are located in the European Economic Area (EEA), we process your personal data on the following legal bases under Article 6 of the GDPR:

- Legal obligation (Art. 6(1)(c)) — processing necessary to comply with tax, accounting, and other legal requirements.
- Consent (Art. 6(1)(a)) — where you have given explicit consent, such as for optional communications. You may withdraw consent at any time without affecting the lawfulness of processing carried out before withdrawal.
